Immortals

Fushi

Voiced by: Reiji Kawashima (JP), Jacob Hopkins (EN)

An immortal being who takes on the forms of various people and creatures it comes across. With each interaction, Fushi becomes more like a human.

Achievements in Ignorance: Fushi, faced with a nobleman begging him to bring back his daughter who has just died, says he doesn't have that kind of power, and the most he can do is create a lifeless copy of her body, and demonstrates to prove it before he leaves. Unbeknownst to him, the daughter is revived in the copy he created, proving that Fushi does indeed have the power to revive the dead.
Affectionate Nickname: The translations in the manga have others referring to Fushi as "Immo".
The Ageless: Subverted. If Fushi stays in a certain form for a long time, he can age like a normal person. However, when he dies, he reverts back to the forms original age, and if he shifts into another one, it will reset as well.
Ambiguous Innocence: Despite seeing many deaths and horrors throughout his life, Fushi still doesn't understand a whole lot, especially romance. Such as one of Mizuha's classmates telling him to stay away from Mizuha because she was a slut. Not understanding this, Fushi asks what that was and when the student says "promiscuous", he still has no idea what she's talking about.
Armor-Piercing Question: The Beholder throws him one pointing out how unrealistic Fushi's plan to destroy the Nokkers is, and that the immortal was neglecting his friends because of his fixation on the Nokkers, despite having revived them to live together as a family in first place:
Beholder: Well, do want fight them for, say, a hundred years? They'll simply double their number in that period. And now that you mention it, didn't you say wouldn't return to home until you eliminated every last Nokker? So when are you going to return? In two hundred years? Four hundred?
- Right after that, Fushi still tries to insist that he can't accept that the Nokkers live people's lives for them, the Beholder points out that he's doing the same thing by using the Nameless Boy body:
  Fushi: No matter what the reason, I can't let Nokkers get away with the arrogance like living out a person's life for them! It makes me sick!
  Beholder: Do you have room to talk?
  Fushi: S-sure I do! I not like the Nokkers! I didn't steal anyone's body! Using someone's body without... without asking... that's just like stealing!
  Beholder: Oh? Then you talked to the boy whose body you're using now?
- When Fushi expresses his desire for his friends to live with him forever, Messar question if he was asking them to live in a cycle of life and death forever just like him, causing him to run away in fear of being hated by them:
  Messar:I get it.You want us keep living, dying, living again like you? Forever?
Bad Powers, Good People: Downplayed. In order for Fushi to transform into other people, the person needs to be dead for him to use their body as a vessel. If Fushi wanted to he could get vessels much faster if he just killed the people he meets but he abhors the idea of taking lives and refusing to use his abilities in that way.
Berserk Button:
- Causing harm to one of Fushi's loved ones and friends ensures a violent response from the immortal. Ask the Nokkers and Hayase if you doubt that.
- Fushi doesn't take to Nokkers stealing the forms (and thus his memories) of the people he once lived beside very well and will stop at nothing to defeat the culprit to get them back. Especially the form of the Nameless Boy.
Big Eater: Fushi tends to eat a lot despite how thin and frail his usual form appears to be.
Break the Cutie: As Fushi grows and becomes more human, he repeatedly experiences the death of loved ones around him through various circumstances, all of which shake him greatly, but when he has to deal with Pioran's natural death and realizes that he is destined to see everyone he cares about eventually die, he decides to live like The Hermit for decades so he doesn't have to go through that pain again. Fortunately, after Kahaku and Bon pulled him out of his isolated lifestyle and helped him with the Nokkers, and mainly after Fushi discovered his power to bring his friends back to life, he finally recovers and start having a dream for himself.
Brutal Honesty: Given how innocent he is and the fact that he doesn't like spending time with people. Fushi does not like to mince words.
- Inverted when Mizuha asks about her ancestor, Hayase. Instead of telling the truth about Hayase and the atrocities she committed, Fushi decides to say qualities that don't apply to Hayase but would be appropriate if he was referring to Kahaku, without saying that he actually hated her.
- Played for laughs where Fushi blatantly insults the Beholder (as Satoru) in front of Sumika, who thinks he's bullying Satoru. Fushi was quite frustrated with the Beholder, but just doesn't realize that in the eyes of the public, he's throwing angry words at a little kid.
Celibate Hero: Although Fushi understands that love is something important, because he is immortal, he believes that even if he experienced it, over time it would become something that does not matter, so he does not intend to have a romance with anyone.
Character Development: One of the most praised aspects of the story by critics and fans alike is Fushi's growth, praising the execution of his development from a divinity to a human as a result of connections forged with the individuals he meets.
Chick Magnet: Once he starts his school life, Fushi is quite popular with the girls.
Complete Immortality: Theoretically, he can be put into a state in which he is utterly helpless either through the Nokkers absorbing every single form and memory he has or something else like being dissolved in molten metal until he cannot form any coherent thought. However nothing so far has been shown to be capable of putting him down for good. It's very strongly implied that he is the same kind of being as the Beholder, and Fushi was explicitly created to eventually replace the Beholder, who in turn confesses will eventually die. By this logic, Fushi is not eternal and will have to make a replacement at some point as well.
Death of Personality: Downplayed. Partially happens to Fushi whenever the Nokkers steal the vessel form he is in by killing him in that form. He forgets who the vessel once was and can only regain his memories of them by defeating the Nokker that stole the vessel.
Didn't Think This Through: Although Fushi is well-intentioned and seeks the happiness of everyone around him, he often does not think about the consequences of his actions, especially in the "New Age", which proves that he is still immature despite his many years of life. Some examples:
- Fushi finally manages to apparently exterminate all the Nokkers on the planet so that he and his friends can live in peace. However, he decides to revive each of them in their homelands as he explores the world to find a place where they can live together as a family, without considering how unprepared they were to adapt to the modern world and also how it would make it difficult to bring them all together again.
- Uninterested in the test in front of him, Fushi decides to make a copy of his body and go looking for Nokkers somewhere else. Surprisingly Realistic Outcome, the teachers notice that "Fushi" suddenly passed out in the middle of the test, prompting them to call an ambulance to save the husk that Fushi left.
- When Fushi temporarily transforms into Tonari's friends to hide with Mizuha from an angry Sumika, he decided that he wanted to make Tonari's friends dreams come true by doing the things that they wanted to do, now being fulfilled in the Modern Era. He had good intentions of appeasing their spirits and honoring them, but Tonari accused him of toying with their spirits for a date with Mizuha. Tonari late apologized for lashing out at him and realized that as much as her friends were a huge part of her life, they were also part of Fushi's life too. But by this moment, Fushi's already faced some problems with the new Nokkers beforehand and was too jaded to pay attention towards Tonari.
- Overall, Fushi's plan to revive his friends in a peaceful world so they can live Happily Ever After ends up suffering a Deconstruction. First, Fushi failed to take into account that all of his friends are Fish out of Temporal Water and they would have taken some time to adapt to the new environment, having believed everyone would automatically be happy in a peaceful world. Second, Fushi thought he would revive them whenever they died forever, not having thought about the possibility that they would decide to move to afterlife until Tonari pointed it out to him. And finally, Fushi believed that his friends would stay with him for their entire lifespan and is genuinely shocked when some express the desire to leave and go their own way one day.
Edible Theme Naming: Fushi gives the name of asian dishes to the turtles that hatch from the eggs he laid like Shumai, Gyoza, Ramen, Twice-Cooked Pork and Shop Suey.
The Empath: Fushi is able to feel people's feelings, especially pain and love. In the manga, when a black bubble appears it means that someone close to Fushi is suffering; on the other hand Fushi will literally see Love Bubbles around the person who is in love with someone.
Eyes Are Mental: Whenever Fushi transforms into someone else, he retain the same Supernatural Gold Eyes.
Hates Being Alone: While he'll endure being alone to protect those he loves, it's clear he always craves companionship in one way or another and still ends up forging bonds with those he gets close to.
Healing Factor: One of the main reasons why it's hard for Fushi to die. However, even if his wounds do heal quickly, he can still feel the pain.
The Hermit: Tried to live like this for a while in hopes that it would save more lives than if he actively sought out the Nokkers. It doesn't work and he's forced back into the world to find a new way to annihilate the Nokkers.
The Hero Dies: Not permanently, but the chapter "The Death of an Immortal" features the one and only time the Nokkers manage to steal every form he has, leaving him as a helpless orb that can't even think. Fittingly, this moment causes the Darkest Hour of the series, and Bon has to kill himself in a desperate gambit to give him a usable shape.
Heroes Prefer Swords: When fighting, he mainly uses swords, even in the modern age.
Heroic BSoD: In the Modern Era, Fushi starts to develop conflicted feelings when he finds out that the Nokkers have not gone extinct and in fact got even stronger through using microscopic forms. He's hesitant when he first encounters the Mimori Nokker, where he struggles to convince himself that it's just a Nokker. And it hits him worse when the Nokker impersonating Izumi shows very human-like emotions and does not even fight back, thus leading him to spare the Nokker with Mizuha. And the fact that Mizuha chose the Nokker over her real mother hurts Fushi even more.
Hopeless with Tech: In the Modern Era, Fushi's very awkward with the new technologies of modern society while everyone he revived adapted to the technologies much faster. Although, he does show interest in some things like the smartphone and a circular saw used by the Mimori Nokker. And when he was told to delete photos on Izumi's computer by Bon, Fushi literally believes there are pictures in the computer's monitor and mistakenly tries to open it, ending with him just tossing the whole thing into the ocean.
Humanity Ensues: How Fushi feels as he slowly learns about the world, and he fully settles into it after spending 4 years with Gugu. Deconstructed as the series goes on as Fushi is not human, and his humanity and feelings become a very heartbreaking source of pain for him. As he develops as a more and more powerful shapeshifter immortal, he starts to grow godlike and his human attachments grow thin.
I Want My Beloved to Be Happy: A platonic version. When Fushi realizes that he will outlive all of his friends and that one day they will die a final death and leave him behind, Fushi begs them not to leave him alone. After witnessing the turtles hatch from the eggs he laid (read Surprise Pregnancy below if you want to understand), he is at first happy but tries to prevent the hatchlings from going to the ocean, saying they would live better with him. Seeing that the hatchlings were still trying to go to the ocean, Fushi realizes that he was being selfish and that everyone were kind to him from beginning to end. So he releases the turtles into the ocean, cuts his hair and decides to prioritize his friends' happiness over the his from then on.
Immortal Immaturity: Although Fushi is centuries old, he is definitely not wise and mature, which ends up being a problem in the "New Age" where Fushi is ignorant of social norms, to the point that does a terrible job of not drawing attention and causing him to have a bad reputation at school.
Immortality Through Memory: Fushi is physical manifestation of this trope. When someone important to him dies, he earns a vessel that allows him to assume their shape and abilities at the time he last saw them.
Important Haircut: In the modern era, after an epiphany Fushi cuts and dyes his hair, indicating his commitment to living like a normal human.
In Touch with His Feminine Side: In the Modern Age, as Fushi goes clothes shopping with the other girls, Tonari points him to the men's section and Fushi vehemently says, "Sometimes I wanna become a cute girl and wear cute clothes, okay?!" While he was getting these clothes for Mizuha, he also has no qualms turning into one of his many female forms when he feels like it.
Laughing Mad: After killing a Nokker, we see an adult Fushi laughing crazily.
Literal-Minded: He sometimes takes things at face value and doesn't always get the jokes people make or their sarcasm.
Logical Weakness: Besides his Healing Factor, he is still bound to the rules of whatever form he takes. As such, all of his human forms are very vulnerable to getting knocked out through poison and sleeping substances, which is a major problem for him on several occasions, as that can truly render him helpless for extended periods of time (for comparison, killing him won't slow him down for more than a few seconds, a minute tops. When knocked out he can be out of it for hours on end) He eventually gets around this when he gets Tonari's form, as she trained her body to be resilient to all sorts of poisons specifically so that, once she died, Fushi could use her form to overcome this weakness.
Lust Object: He is this to Hayase, who has an overwhelming desire to keep him for herself and do whatever she wants with him, using trickery and physical violence to do so.
Meaningful Name: His name can mean "immortal".
Money Dumb: As he can literally create money out of himself if he wants, he doesn't understand why doing it in the New Age is a bad idea, especially when explained about inflation. He also got into a bit of trouble because of it in the past, where he made money whether or not the people wanted it without thinking of the consequences of his actions.
Mystical White Hair: Fits his supernatural nature, although his default appearance is that of an ordinary boy.
"Not So Different" Remark: As the Beholder points out, for all of Fushi's indignation about the Nokkers stealing people's bodies and living their lives for them without asking, Fushi doesn't have room to talk because he's mostly using the Nameless Boy form and hasn't asked to use his body before his death.
No Social Skills: Downplayed and Justified. Fushi has a decent grasp on most overt social nuances, but he ends up being that in Modern Era, since he is still naive about much of the modern world and, because Fushi decided to give priority to investigating the Nokker that still exist in the modern era, he ends up missing several classes at school. Although the teachers allow part of Fushi's behavior because they think he is a Funny Foreigner who has not yet adapted to Yanome's rules and customs, Fushi has consequently acquired a bad reputation.
Not So Above It All: While he rarely tries to act like he knows how to solve everyone's problems, there are still moments were he gets amusingly flustered. Such as when Mizuha finds him as a turtle laying eggs and, after he shifts back to normal, tries to hide the eggs while embarrassed. She laughs at Fushi's antics while the immortal can only blush and try to act like him laying eggs was a normal thing.
Playing with Fire: Of a sort. After being captured by the Benett Church, Fushi was trapped inside an iron cube, and melted iron was thrown inside to ensure that he would die. However, thanks to his regenerative power he managed to stay alive, and because of the method that was used, Fushi obtained the power to emit heat from his hands strong enough to melt the iron that imprisoned him.
Please, Don't Leave Me: Once he becomes aware of the possibility of his friends decide to go into the afterlife and preventing him from reviving them again, he asks them not to leave him.
Fushi:...Don't die...and leave me behind...
The Power of Creation: Fushi is able to recreate any object, ranging from coins, food and clothes to an entire castle, without a definite limit on the amount and size of what he is capable of creating. That said, Fushi gets tired of using this ability if he doesn't have a chance to rest and he can't create pure flame, pure water and things he has never seen.
Physical God: After the modern timeskip, he is basically one step away from it. He is extended through all of Earth and can teleport at will to any location as well as feeling any movement or sensation out there. However, he also confirms with the Beholder that he is not omnipotent or omniscient yet.
Really 700 Years Old: The series takes place over a very long period of time with several timeskips. By the time of part 1's finale, he is 233 years old. In the modern era, Yuki says that Fushi is approximately 800 years old.
Resurrective Immortality: His body can be killed, but he will always revive after a period of time. He also resurrects more quickly as his body adapts to whatever kills him.
Sapping the Shapeshifter: The only way the Nokkers could defeat him is by 'killing' him multiple times, literally absorbing each shapeshifting form he has, which if done enough times would turn him into a non-sentient form like a stone, or his original form as a marble-like sphere.
Shapeshifter Default Form: Fushi takes to using the Nameless Boy's form by default in order to honor his memory and final words to remember him forever. Even after attaining a myriad of useful forms, Fushi admits that he feels he identifies with the boy's form the most.
Shapeshifter Weapon: Fushi learns he can create things he's interacted with before from his body.
Supernatural Gold Eyes: He has golden eyes that indicate his supernatural powers. No matter who Fushi becomes, his eyes stay the same.
Surprise Pregnancy: A very bizarre case. When exploring the sea in the form of a sea turtle, Fushi did not know that the turtle he had transformed into was about to lay her eggs. As a result, shortly after transforming, Fushi instinctively went to the beach where he laid his eggs.
Survivor Guilt: Seems to suffer from this the longer he lives, and when isolating himself on an island, he ruminates about how guilty he feels that he is still alive while everyone he came to love is gone.
Took a Level in Badass: Over the course of the series, he obtains more and more varied and useful forms, as well as sharpening his overall skills as a shapeshifter. After the modern timeskip, he is almost a god, having extended himself all over the planet.
Thou Shalt Not Kill: Due to his The Empath -tic powers that force him to feel others' feelings and emotions, Fushi is adamant in his idea of not killing or letting humans or animals die, without caring how evil they would be. Unfortunately for Knockers, they are not on Fushi's mercy list... at least for now.. As expected, in the modern era, Fushi, after facing Izumi's knockers and discovering they are capable of feeling pain and love, accepted that no every Knockers are no longer the monsters they use to be and he swears to exterminate. In the final battle he refused to fight to kill.
Unable to Cry: Although Fushi has gone through many sorrows and tragedies, he never cried in any of these events despite his suffering. This ends up being even pointed out by the Nokker inside Mizuha, who calls him a liar for saying that he would cry if Mizuha died.
What Is This Thing You Call "Love"?: Despite his centuries of existence, he has never experienced any romantic relationship in his long life. When Mizuha asks if he likes (loves) someone, Fushi innocently declares that he loves everyone around him, proving that he understands friendship and familial love, but when it comes to romantic love, he's dense. He endeavors to learn more about it after finding that it may be the key to defeating the Nokkers of the Modern Era.
Who Wants to Live Forever?: Fushi starts asking this when he sees all of his friends die around him and wishes for permanent death.

The Beholder

Voiced by: Kenjiro Tsuda (JP), Cory Yee (EN)

A mysterious figure who follows Fushi around, and can only be seen by him. He claims to be the one who created Fushi, tasking him to know everything about the world and getting rid of the Nokkers. Only until he achieves that will he give Fushi "freedom".

All-Powerful Bystander: He's an incorporeal entity who can't be killed by any of the other cast and admits that he could easily defeat all the Nokkers if he wanted to but he only cares about Fushi's growth, not bothering with the tragedies and deaths that happen around him as long as they are useful to Fushi's progress.
Aloof Ally: As his creator and mentor, he's on Fushi's side. That said, he is indifferent to Fushi's suffering and is only interested in his growth so that one day he can replace him.
Armor-Piercing Question: When Messar then asks if he created Fushi to replace him because he will vanish or because he wants to vanish, he has no answer.
Become a Real Boy: In essence, his ultimate goal. After giving Fushi the power to reconnect, he decides to live in the form of a boy who is taken into an orphanage and named Satoru. After a series of coincidences and Fushi reuniting with him, he reveals to Fushi that his powers and memories will eventually disappear in four years and from then on he will be an ordinary human. Fushi is baffled to discover that the Beholder, an omnipotent and apathetic being, has decided to transform into a mere human.
Big Good: Deliberately played with. Albeit helpful in dealing with Nokkers, the Beholder is otherwise very cold and indifferent to everything he doesn't find useful for Fushi's growth. For example, when Fushi decided to isolate himself so that nobody would be killed by the Nokkers, the Beholder reported the "good news" that the Nokkers decided to attack other people anyway and that now Fushi has no reason to isolate himself anymore. Fushi, in turn, does not like him one bit.
Do Not Taunt Cthulhu: After explaining why he will not interfere in the future battle that will take place at Renril, Messar tries to kill him by stabbing him in the back with his sword. Not only does this not work, but Messar is thrown away, the Beholder removes the sword, folds it like paper and disappears. Without touching Messar or the sword. Even in his human body as Satoru, he reveals that he still has remains of his defensive powers left within him and easily defeats the Funa Knocker trying to assassinate him by turning Funa's body into a flower before extracting the Nokker and burning it in his hands.
In-Series Nickname: Bon nicknames him as "Mr. Black", and uses it to summon him on the spot.
In the Hood: He's always draped in a black cloak, with his face barely visible.
Invisible to Normals: Only Fushi and Bon can see the man. To normal people, Fushi is talking to himself.
Jerkass Has a Point: Often what he says is insensitive and even cruel to Fushi's feelings, but the points he raises are usually accurate:
- When Fushi separates from Gugu and Rean to distract her nanny, the Beholder narrates that he will hardly be able to get back to them as he notes that since the last battle Fushi has not been able to get anything useful to use against the Nokkers and the enemy has the element of surprise. Turns out he's right and it ends up being Gugu who defeats the Nokker.
- After Fushi was saved by Gugu from the Nokkers, the Beholder warns him that the Nokkers would learn from their defeat and advises him to abandon his new family so that he becomes stronger for the next attack, but Fushi says that Gugu is strong and he will defeat the enemy. Unfortunately the Nokkers prepare for Gugu's Booze Flamethrower, and although they managed to repel the attack, Gugu ended up perishing in the battle.
- Traumatized by Gugu's death, Fushi decides to turn himself into an unconscious stone for the Nokkers to stop chasing him, but the Beholder makes him return to his human form and warns him that the Nokkers would not give up easily, and if they attacked him while he was in the form of a stone, he would have no chance of defending himself.
- When Fushi says he didn't want kill anyone in Jeananda's tournament, the Beholder says that he had already caused the deaths of several people, including Gugu. Fushi is outraged by the accusation, but the Beholder explains that just as Gugu chose to hasten his death to save Fushi, the other contestants also chose to hasten their deaths to achieve their goal and that Fushi should not feel guilty about the fate of those who chose to die. Harsh words, but true.
- Seeing that Fushi was wishing to be with Pioran but afraid of her being involved in his battles against Nokkers, the Beholder warns that regardless of Fushi's choice she will die anyway as that is the fate of all living beings. And indeed, much to Fushi's sadness, Pioran eventually suffer a peaceful death.
- In the Modern era, the Beholder, now called Satoru, points out to Fushi that coexisting with the Nokkers is not necessarily a bad thing, plus he was neglecting his friends because of his fixation on creatures and in the end he also makes a remark that Fushi is not that different from the Nokkers.
Lack of Empathy: Doesn’t seem to care at all about the people around Fushi beyond how they affect his growth, which is just one reason Fushi doesn’t like or trust him. For example, when Bon asks if he could defeat the Nokkers alone, the Beholder believes he could but refuses to try because even though several people will die in the conflict these deaths will serve to Fushi's growth.
Time Stands Still: In addition to the various other powers he has been shown to have, the Beholder is also able to stop time.
The Maker: He claims to Fushi that he created the immortal being. He tells Fushi that, once he sees everything that there is in the world, he would grant him "freedom".
Not So Omniscient After All: Even he could no longer feel the Nokkers once they decreased in size, and like Fushi, he believed that the creatures had been exterminated. Double Subverted after declaring that he in fact could have erased every Nokker if he wanted.
The Omniscient: He knows a lot more than Fushi, such as how far he can push his abilities, offer confusing advice and sense where the Nokkers will appear.
Pet the Dog:
- When Pioran asks on her deathbed for the Beholder to make her be reborn in a way that helps Fushi, he fulfills her wish and is implied that he made her reborn in the form of the white horse that Fushi would find centuries later. Although it is possible that he only did this because he believed it would help Fushi's growth, he still had no duty to grant Pioran's request, but he did it anyway.
- After Fushi wakes up in the Modern Age, he then grants him the power to reconnect, ensuring that Fushi does not lose the fruit of centuries of his efforts, and before leaving, the Beholder sincerely congratulates Fushi and says that it's time for him to celebrate.
The Stoic: He never changes his neutral expression compared to Fushi who gets more emotive the more he experiences the world. Even in the modern age as a child, he still wears the same unchanging expression.

Fushi's Companions

In General

Back from the Dead: Once Fushi becomes aware of his ability to revive the dead, they are all revived to fight the Nokkers in Renril. After they won the battle, Fushi promises to bring all them back when he exterminates all the Nokkers in the world, fulfilling that promise and reviving them in a new era.
Death Is Cheap: Thanks to Fushi more or less giving them Resurrective Immortality because of their close-knit bonds, these guys gradually get so used to dying and being revived that as of the Distant Future Era, they treat the whole process as more like casual events than anything else. They've even started keeping notes and comparing them with each other every twenty years just to see who got the "coolest" and "lamest" deaths among them, with Tonari and Messar taking the bottom spots for lamest due to racking up a high number of Undignified Deaths over the eons (the former for constantly taste testing her own experimental poisons, and the latter for always getting drunk and wasted in the worst places.
Family of Choice: For Fushi, they are the closest to a family he had during his long immortal life. Simply put, all the major relationships in Fushi's life have been analogues to major relationships for a human being.
- March: Mother
- Gugu: Brother
- Pioran: Grandmother
- Tonari: Sister
- Bon, Kahaku and Eko: Friends
- Kai, Hairo and Messar: Battle companions
- Oniguma and Ilgard: Team Pet
- Mizuha: Possible Love Interest
Dysfunction Junction: All of Fushi's companions have sad or complicated pasts but all united in making Fushi happy.
- March is a cheerful and innocent girl whose dream is to grow up but unfortunately she was chosen to be Targeted Human Sacrifice for her village.
- Gugu was abandoned by his brother and suffers an accident that disfigures his face, forcing him to wear a mask to avoid being mistreated.
- Tonari's father was exiled to Jeananda after being accused of murdering her mother, and believing in his innocence she chose to accompany him in his exile. On the island, watching her father commit murders so they could survive, Tonari becomes disillusioned and comes to think that he probably killed her mother. After her father is killed by the inhabitants, she is forced to survive alone.
- Pioran backstory is largely unknown, but it is rumored that she poisoned ten Yanome soldiers. When Fushi first meets her, she is a prisoner of Yanome who is forcibly enlisted as a shaman to perform the Spirit Bear ritual.
- Bonchien's backstory appears to be the least dysfunctional. As a prince and heir to the throne of the kingdom of Uralis, he had a good childhood and grew up with a caring family who loved him but all the pampering made him a Manchild, which led his father to decide that his younger brother would be a better heir to the throne. This decision motivated him to find Fushi to prove to his father that he is not an Inadequate Inheritor.
- Eko's backstory is one of the saddest of the group. Her village was attacked by Nokkers, forcing her and her brother to flee to survive. Unfortunately both are captured as slaves and kept in inhumane conditions and after Fushi rescues them her brother ends up passing away soon after.
Fish out of Temporal Water: Because Fushi took nearly six hundred years to exterminate the Nokkers from the planet and make the world peaceful for him and his friends, when he finally decided to revive his comrades, they found themselves in a strange new environment, forced to adapt to the new conditions and how to live thereafter. Surprisingly Realistic Outcome, everyone encounters some problems in the process, with Messar and Bon faring better at adapting, while others like Gugu and Hairo have been bullied in the Modern Era. They at least adapt to the changes faster than Fushi, probably thanks to the fact that they were able to see the world as Faie while Fushi was inactive. However, some of his companions supposedly preferred to stay close to Fushi, as Tonari notes her boredom from spending centuries next to his side.
Immortal Immaturity: Even after living for more than a millennium as of the Distant Future Era, none of their "younger" or more irresponsible members show any signs of having matured over the ages, especially Messar.
Resurrective Immortality: As of the Distant Future Era, they have essentially become this as Fushi's eternal companions. Technically, they're still mortal and do eventually die from old age, sickness, accidents, fatal encounters, or just plain stupidity, but are always happy to be revived again and again in their peak forms so they can keep accompanying Fushi as he continues to travel around the world.
Resurrection Teleportation: Fushi can revive his friends wherever his roots are, but once Fushi revives them he cannot teleport them until they die again. This caused problems in the Modern Era when Fushi revived them in their homeland, spread out and away from each other.
True Companions: Even death is unable to separate them from Fushi, to the point where they gladly allow him to resurrect and restore them back to their peak physical forms again and again so they can accompany him forever even beyond their natural human lifespans.
Undying Loyalty: They are all loyal and seek to make Fushi happy during his immortal life. The bonds they form with Fushi are so strong that they forego going to Paradise and stay with him instead as spirits, and later as resurrected humans.

March

Voiced by: Rie Hikisaka (JP), Sarah Anne Williams (EN)

A young girl from a village who Fushi meets. She dreams of growing older so she can become a mother. She's the one who gives Fushi his name.

All-Loving Hero: March is full of kindness and it is nearly impossible to make her hate someone (Hayase is an exception for obvious reasons). She readily accepts Fushi despite the fact that he is clearly not a human and is willing to become his mother, although many adults fear he is a demon. For the same reason, she accepts to take care of Oniguma's injuries, even though the beast almost managed to kill her and Parona before.
Arc Hero: She's the focus of the Yanome arc.
Back from the Dead: Twice. Fushi creates a shell of her on the wall in case of a Nokker attack, and she'd remain as such as long as the rope was attached to the wall. However, the rope is severed and March awakens, not remembering her previous death. This resurrection doesn't last long, however, because March opts to die again rather than grow old without Fushi, and lets herself get poisoned by Tonari. Much later, she's resurrected again in the Modern Arc, this time under much happier circumstances with Fushi by her side, and lives to a ripe old age.
Big Sister Worship: March loves and respects Parona very much because Parona was a loving sister-figure to her. March never forgot about her, as shown in the Modern Era, where she still misses Parona.
Cassandra Truth: On March's first day at the school, a girl starts teasing her headband, prompting her to impulsively say that the accessory is 500 years old. None of the children believe her, calling her a liar and leading her to had a rough start at school.
Childish Tooth Gap: And quite a big one.
Death of a Child: March dies from an arrow wound she received to protect Parona. Also, when Fushi refuses to wake up to try and eradicate all the Nokkers while he's "asleep", March refuses to leave his side and also refuses to look after herself. Tonari and the others decide it would be kinder to kill March with one of Tonari's poisons, and she dies next to Fushi. Happily averted in her second resurrection when the story reaches the modern day era. March quickly adapts to a relatively peaceful modern life, and a Time Skip later reveals that she lived to a ripe old age, still with Fushi and their other closest companions by her side.
Fluffy Tamer: Taming the Oniguma certainly qualifies March as one.
Goal in Life: She wishes to become a mother, more than anything else.
Humble Goal: All she wanted was to grow up into an adult and become a mother to raise a lot of children. She technically gets to live this dream through Fushi when she first meets him and happily declared herself his mother. This dream gets partially fulfilled at the conclusion of the Modern Day arc, where a Time Skip reveals a now elderly March living a happy and content life with Fushi and her other companions despite never having found a partner in the modern world to raise her own children with.
Outdoorsy Gal: Since she grew up near the forest, she has the ability to climb up trees.
Mercy Kill: Tonari and Hairo, seeing how devastated March was because she couldn't grow up with Fushi until he wiped out the Nokkers, which would take centuries and far beyond her lifespan, decide to give March a poison to euthanize her so she doesn't go through the pain of having to move forward without Fushi.
Never Learned to Read: Justified. The Ninanna does not have a written script, and as a result, March has no way of writing a letter that her parents can read. So when she tries to write to her parents, she simply puts her hand-print on the letter to mean she is doing well.
Nice Girl: She’s cheerful and friendly and helps Fushi come closer to humanity.
Parental Substitute: Acts like this towards Fushi when she first meets him. In the modern age, he even bows down to March and, while she's physically and mentally younger than him, still treats her like his parental figure if he upsets her.
Playing House: How she came to bond with Parona with her as the mother and Parona as the father.
Prone to Tears: March tends to cry a lot, especially when she's frustrated or hurt.
Targeted Human Sacrifice: March ends up being selected to become the sacrifice of her village like the other young girls before her to appease the bear spirit.

Oniguma

A huge white bear that lives in the Ninanna forests. Because of his extraordinary size and appearance, many believe that he is the Oniguma of the legends of the region.

Androcles' Lion: After being captured by Hayase and her soldiers, March took care of him and his injuries for months. Although she was unable to save his life, the bear died grateful for all the love and care she had for him. Once they were revived, the bear proceeded to follow and obey her to the point that Kai called March a bear whisperer.
Annoying Arrows: He is covered with arrows and sticks, all stuck in his body. As March noted, this only gave the bear an even more intimidating appearance, which is why people started calling him the Oniguma despite being just a normal bear who likes to eat human meat. In the Modern Era, Fushi and his friends help remove the arrows off his back so that the arrows don't hinder him anymore.
Bears Are Bad News: Definitely, at least in the beginning of the story. His absurd size, ferocity and strength made many believe he is the legendary Oniguma. He killed Fushi twice and would have devoured March and Parona if Fushi had not saved them. Fortunately, he lost that status once he died and became attached to March.
Died in Your Arms Tonight: He dies in March's arms while she takes care of his injuries. Through Fushi, the bear thanks March for taking care of his injuries and comforting him in his last moments.
Mighty Glacier: By far he is the strongest among all of Fushi's companions/vessels, but on the other hand he is slow and Fushi has difficulty dodging attacks in this form, being one of the most stolen vessels by Nokkers.
Shrouded in Myth: Many people who see this bear for the first time think that it is the legendary Oniguma. However, basically it’s just a normal, overgrown bear angered by the constant pain of the arrows and with a taste for human meat.

Gugu

Voiced by: Ryōko Shiraishi (child), Taku Yashiro (teen) (JP), Erica Mendez (child), Bryce Papenbrook (teen) (EN)

A commoner boy who saves a noble girl from a rolling log and now has to wear a mask over his head. He believes he's become ugly after the accident and calls himself a monster, which allows him to easily bond with Fushi who he calls his brother.

All of the Other Reindeer: After Gugu gets an injury that severely disfigures his face, to the point where he has to wear a helmet to hide it, when people see his face, they recoil in fear and call him a monster. At one point, Gugu is kicked out of a job not days after getting hired because his boss's son ordered him to leave, calling him an inconvenience and a monster.
Animal Motif: Lizards or dragons, best noticeable with the designs of his helmets, and fitting for his fire-breathing ability.
Arc Hero: For the Takunaha arc.
Bash Brothers: With Fushi, especially while taking on a large stone-clad Nokker. He also considers Fushi his monster brother. In the modern age, he's also very protective of Fushi, especially when Mizuha seems attracted to him.
Berserk Button: Don't damage his mask. It was a gift from Booze Man and has immense sentimental value for Gugu. When a delinquent assaulted him, he only decided to fight back when he realized that his mask had been cracked.
Big Brother Instinct: Considers Fushi to be like a younger brother, and treats him accordingly. He gets really pissed off when Pioran and Beer Grandpa jokingly suggest ways they could exploit Fushi for money, and when it’s pointed out that people would be after Fushi for his powers, Gugu declares that he’d protect him before that could happen. He fights like all hell to save Fushi from attacking Nokkers, both the one in the woods and the one at Rean’s house (during the latter, he even outright ignores her attempts to get him to stay with her). One of the reasons he rejects his brother’s offer to start anew is because he doesn’t want to abandon Fushi. In the Modern World, he’s initially skeptical towards Mizuha, having mixed feelings about her advances towards Fushi (although he states that he’d support Fushi anyways if he really wants to go for it).
Big Brother Mentor: Along with Pioran, he was one of Fushi's most important mentors, teaching him how to clean, cook and work. Four years later, Fushi became able to live as a human thanks to Gugu and the rest of the family. In the Modern era, he even does what he can to look after Fushi who's still not used to the social customs or how to properly act.
Big Little Brother: As he gets older, he ends up towering over Fushi, whose physical body is older than Gugu's and is shown that he even towers over his own biological brother.
Booze Flamethrower: Gugu, after being healed, had a "special organ" implanted in him to distill alcohol that is removed through his mouth. He learns to eject alcohol from this organ into a flame as a form of attack.
Butter Face: Gender Inverted. Gugu has a very muscular and attractive body, but because of the accident that disfigured his face he needs to wear the mask to avoid being mistreated.
Cannot Spit It Out: His family wonders why he doesn't just tell Rean he likes her.
Cool Mask: Especially the one he gets in his teens that looks like a dragon. Everyone in the Modern Era really likes his mask and often ask for pictures with him.
Death of a Child: Gugu dies protecting Rean from the rubble of her fallen home. He was likely only a teen when he died.
Dogged Nice Guy: He has a crush on Rean and really likes her, but he’s not sure how to convey it.
Dramatic Irony: He dies protecting Rean; the first time he protected her (from the fallen log) led to his deformity, and the second time (from the fallen rubble of her house) led to his death.
Expressive Mask: In the modern age, his mask actually emotes with him sometimes, as if he's expressing shock. In the anime, it's given a lot more expressions than his manga counterpart with the eyes in particular moving a lot.
The Faceless: His full face is never shown after the accident, and at most, the viewers get a peek of his eyes. The anime subverts this by showing his full face in the opening credits of the show and before his accident.
Family of Choice: The old man, Pioran and Fushi. He even explicitly calls Fushi his "monster brother" as they bond with one another.
Fire-Breathing Weapon: Gugu finds out that the alcohol he distills in his body is extremely flammable and uses his mask to breath fire on his enemies. His second mask fittingly looks like a dragon.
Foolish Sibling, Responsible Sibling: His brother kept spending all of the money he was trying to save, and Gugu still gives him Rean's ring instead of spending it on himself. While he doesn't forgive his brother for abandoning him, he seems to make up with him in his vision of the afterlife. His older brother also attempts to reconcile their relationship and is heartbroken at finding Gugu's dead body amongst the rubble.
Friend-or-Idol Decision: In the Modern Era, Gugu has to choose between staying with Fushi in Yanome, where he is being bullied, or returning to Takuhana where he knows he will be happier but will have to abandon his brother. Subverted in that Gugu ends up deciding to stay, but Fushi decides to buy a ticket so Gugu can happy in Takuhana, which he accepts.
He Cleans Up Nicely: Gender-inverted example, Gugu would normally go shirtless, but in the Modern Era, he wears a jacket with slacks for casual wear and a boy's school uniform in high school.
Hopeless with Tech: Subverted in the Modern Era, where Gugu easily learns how a smartphone works. Compared to Fushi, who's still getting used to modern technology and terminology, Gugu adapted very well in the modern society.
I Got Bigger: After a few years, he matures into a tall young adult who can easily tower over Fushi's human form and is quite muscular due to his extensive training in order to impress Rean.
I Have No Son!: In this case, brother. When he finds his brother, Shin, beaten and withered in an alley, Gugu decides to give him Rean's ring, but when recognized by him, Gugu says he has no brother before he leaves.
In Vino Veritas: On the rare occasion he gets drunk in order to help Fushi, he confesses to Rean that he was the one who saved her.
The Promise: Promises Rean that they'd go out to pick flowers later. He dies protecting Rean from falling rubble before he can fulfill that promise.
Innocently Insensitive: Curious to see the limits of Fushi's creation power, he makes a small cut on the immortal's hand with a knife to see if he could create it, and then burns him with a torch to see if he can reproduce the fire, without care that he was hurting Fushi. Gugu then says that, since Fushi is immortal and heals his wounds quickly, he has no reason to complain. Gugu would end up receiving a treatment quite similar from Beer Gramps. See Laser-Guided Karma below.
Kids Are Cruel: He experiments with Fushi by placing a burning torch to his hand to see if he could replicate flames, and even pranks him by having him drink alcohol which the immortal promptly spits back up. When Fushi mutters how uncomfortable this makes him feel, Gugu just tells him to suck it up. It's only after Gugu experiences something similar with the Beer Gramps showing how he's using Gugu's body to distill alcohol does he empathize with Fushi more and start treating him better.
Laser-Guided Karma: Shortly after experimenting on Fushi without regard to the immortal's feelings, Gugu discovers that Beer Gramps placed a "special organ" for distilling alcohol inside him. Feeling betrayed and violated, Gugu decides to flee the house, making it necessary Fushi, after being convinced by Pyrona, and Rean to go after him and convince him to return.
Real Men Cook: He's usually the one who prepares the food for his surrogate family, and they note that it's extremely delicious.
Shrouded in Myth: Gugu was pleasantly surprised to discover that he became a legendary figure in Takunaha centuries after his death, whose legend tells that he was a heroic monster who protected the people from evil creatures, with the people holding a festival every year in his honor. Gugu considers this a gift left by his brother, Rean and the Booze Man for him.
The Lost Lenore: After his death, Rean decides she won't marry anyone else, knowing Gugu is with Fushi now.
Took a Level in Kindness: Gugu was a little brash in his youth, but thanks to his character development, he acts a lot more kinder as a grown up. He remains so after his first resurrection and in the Modern Era, where Gugu's a lot friendlier with people and even allows people to take pictures with him.
What You Are in the Dark: After being abandoned by Shin, Gugu finds his brother passed out in an alley, weak and thin. Although he could abandon Shin to his fate, Gugu places in his hand the valuable ring that Rean gave him, despite the immense sentimental value he has for the jewel, rationalizing that even if he sold he would still remain a monster while Shin it might change to be a good for nothing loser to a decent human being.

Tonari Dalton

Voiced by: Eri Inagawa (JP), Anne Yatco (EN)

https://static.tvtropes.org/pmwiki/pub/images/tonari_anime.png

A young girl who dreams of being a writer and cataloguing her journey and findings of the world. At first, she treats Fushi as a means of her escaping the island, but does come to genuinely care for him.

Acquired Poison Immunity: She reveals that she made herself immune to poisons after Hasame tried to knock them out. Due to Fushi feeding her and her friends the poisoned noodles years ago, she started to build an immunity. As she got older, she started experimenting until she had a vast array of poisons under her palette. But this does not mean she's immune to the Nokker's roots, and she ends up dying by these whilst trying to cut out the Nokker in Hasame's arm. And she lost most of the resistance she built after Fushi revives her in her younger body in the New Era.
Arc Hero: For the Jeananda arc.
Back for the Dead: She returns after a 40-year-long Time Skip, now as a middle-aged woman. Only to die soon after. She then gets resurrected in the Modern era... unfortunately back into her teen form.
Backup from Otherworld: Tonari is notably the first of Fushi's companions to proactively help him after dying, which she does by locating Prince Bon as a child, teaching him to take an interest in Fushi, and guiding him to Fushi's location with the help of the spirit of Ricard.
Broken Pedestal: Tonari's mother was murdered and her father was accused and convicted of killing her despite swearing that he did not commit the crime. Believing in her father's innocence, Tonari decided to accompany him on his exile to the island of Jeananda. After that, her father decided to participate in the island tournament in the hope that they would leave the island if he won, and witnessing the violence with which his father killed the other contestants and laughing at being victorious, she realize that her father has turned into a bloodthirsty killer and is probably guilty for killing her mother. Although Fushi points out that the fact that her father has to kill people in the tournament does not necessarily mean that he murdered her mother, Tonari admits that she no longer feels confident in her father's innocence.
Children Are Innocent: Tonari fully believes this. In her view, Jeananda's children either accompanied their parents in their exile or were born there, and that is why they do not deserve to stay in Wretched Hive when they have done nothing to deserve that fate. So when having to pick 700 people to take off the island, she decides to save children under the age of seven, saying they owe them the chance to choose their own destiny.
Hated Hometown: Though not born in Jeananda, Tonari detests the island and its inhabitants, and not without reason: the place is a Wretched Hive with More Criminals Than Targets because other countries exile their scum there, resulting in a land without law and order, full of murder and robbery, having been her dream of escaping the island along with her friends and even tries to convince Fushi that with the exception of the children, the rest of the population was not worthy of being saved. After the tragedy and destruction unleashed by the Nokkers there, Tonari changes her mindset and decides to stay on the island and use her position as leader to make Jeananda a better place, subverting this trope.
Hypocrite: At one point, Tonari tries to convince Fushi to abandon Jeanada and its inhabitants to the Nokkers, saying that half the population is criminal and the other half is tainted by being related to them and therefore they are not worthy of being saved, even though it would mean that she and her friends don't deserve to leave the island by that logic. Similarly, in the Modern Era Tonari treats Mizuha suspiciously for being a descendant of Hayase, despite her own father having been a murderer, which she recognizes is hypocrisy on her part.
Hypocrisy Nod: She recognizes that it is hypocrisy on her part to judge Mizuha because Hayase was her ancestor, since Tonari's own father was a murderer and she knows how painful it is to be judged by the circumstances of your birth. That said, given Hayase's history of descendants, she has reason to be careful and openly asks Fushi not to become close to Mizuha.
Impossibly Tacky Clothes: When Tonari and March go shopping for clothing, Tonari decides to go for a fancy summer dress to wear in town. Fushi thinks that she looks funny in her new clothes and Tonari gets embarrassed over it. Later, after finding a new school to attend, she currently wears a school uniform.
I Was Just Joking: As she dies, she jokingly tells Fushi she'd like to be revived in her youth next time. After bringing all of his friends back to the modern age, Fushi does just that to her annoyance, as she points out she created her old body so Fushi could withstand just about any poison. When he points out she requested to be brought back in her youth, she yells that she was joking.
Jerk with a Heart of Gold: To say that Tonari made a bad first impression on Fushi is an understatement. First, she tricks the immortal and Pioran into being arrested and taken as slaves to Jeananda, separating Pioran from Fushi, and leading him to go fight in Gladiator Games, and once she discovers his immortality, she then proceeds to try to manipulate him for her own purposes. Despite this, Tonari ends up proving to be loyal to her friends and those she cares about, and eventually she grows fond of Fushi and seeks to help him, genuinely apologizing for causing him trouble.
Last Request: She asks Fushi (who doesn't recognize her) to show her the forms of all the people he has met. It's only after she dies does he realize who he had been talking to.
Luminescent Blush: She starts to seemingly grow feelings towards Fushi in the Modern Age as she was reborn in her teen body. This even confuses and freaks her out.
Older and Wiser: When Fushi meets up with her and her friend again, but he doesn't recognize them.
Older Than They Look: Because she jokingly said that she would like to revive her youth, Fushi decided to revive her with the body of when she was 14 years old. As a result, she is a woman over fifty in the body of a teen.
One-Book Author: She became famous because of her diary, her travels coming only in second.
Properly Paranoid: She doesn't trust Mizuhua, mainly as she points out that all of her ancestors have killed everyone in Fushi's group in one way or another, and can't bring herself to commit to trusting her the way Fushi has. As the Nokker in Mizuha awakens, killing her own mother, Tonari is right to be suspicious.
Sins of Our Fathers: Unfortunately, Tonari believes that. When trying to convince Fushi to abandon Jeananda to the Nokkers, she says that half the population is criminal and the other half is tainted for being related to them. Even after centuries she still retains part of that mindset, which she uses to treat Mizuha with suspicion because she is a descendant of Hayase ,although in this case it can be considered Properly Paranoid, but as Fushi points out it is still unfair to Mizuha and Tonari herself acknowledges that she is being hypocritical here.
Thanatos Gambit: For over 40 years, she trained her body to become immune to all sorts of poisons and ailments specifically so that, once she died, Fushi could have an extremely tough human form that specifically bypasses his weakness to poisons and other chemical substances. As heartbreaking it is for Fushi to watch her die, this is completely successful and his usage of her form proves to be extremely useful.
What the Hell, Hero?: In the Modern Era, she gets angry at Fushi when she finds out Fushi used her friends' forms while going out with Mizuha. She accuses him of toying with their spirits for a date with Mizuha. It doesn't help that she had trust issues with Mizuha, who descends from the Hayase lineage. She later apologizes to Fushi because she realized that he only wanted to make her friends' dreams come true and to honor them. Although her friends were dearly treasured to her personally, she accepts that they were treasured by Fushi as well.

Pioran

Voiced by: Rikako Aikawa (JP), Dorothy Elias-Fahn (EN)

An old woman who was kept as a criminal under Hasame's control. She spends the rest of her days following Fushi, teaching him and beating him over the head if the situation calls for it. She may be old, but she's incredibly stubborn.

Dark and Troubled Past: Although details are not clarified, Pioran seems to have had a difficult past. Tonari mentions that she has poisoned ten Yanome soldiers and when Fushi tries to rescue her from prison she says she was "...put back where she belongs".
I Was Quite a Looker: She tells Fushi that she used to be as pretty as Rean in her younger days. When she asks the Beholder to allow her to be useful to Fushi in another life, he grants her the chance to appear how she wants before passing away. The image she chooses reveals, that in her youth, she was very pretty.
Mentor Archetype: Of the several loved ones that Fushi had, she is the one that most fits this trope. She is the one who is primarily responsible for teaching the immortal words, letters and how to live as a human being.
Mentor Occupational Hazard: As the Beholder warned, Pioran eventually dies due to her age, being the first death from natural causes of a loved one that Fushi experiences. Before her death, Pioran tells Fushi that she was happy to have met him and leaves a letter to the immortal in which she asks for him to seek a dream and do what he wishes, like she did.
Parental Substitute: She is this to Fushi. Specifically, she compares Fushi to a grandkid she never had.
Passed in Their Sleep: How she eventually goes, to Fushi's despair.
The Promise: In order to tag along, Fushi tells her that she can't die, which she promises. However, like any old mortal being, she can't keep that promise.
Reincarnation: Implied to be reincarnated as Fushi's new horse, if the mole on its face and general attitude towards the immortal is any hint. It's spelled out clearly on the volume 9 cover which depicts a young Pioran carrying Fushi on her back.
Reincarnation-Identifying Trait: Many years ago, Pioran bit Fushi's left leg when she was hungry and also showed the ability to catch fish without using tools. When Fushi meets the horse, the animal's first instinct is to bite the same leg and also shows that it is able to catch fish on its own, indicating that Pioran has reincarnated as the horse.
Scatterbrained Senior: Played seriously. As she travels with Fushi and gets older, she slowly starts forgetting things to Fushi's confusion and worry, as he doesn't want to lose someone close to him ever again. This leads to him having to carry a struggling Pioran around who tries to fight him as she doesn't understand why Fushi's carrying him or sometimes even who he is. Moments before she passes in her sleep, she regains some lucidity as she gently consoles Fushi and asks the Beholder to grant her wish before she goes.
Screw Politeness, I'm a Senior!: How she justifies having Fushi and younger people do work or fetch food for her.

Bonchien Nicoli La Tastypeach Uralius

Voiced by: Takehito Koyasu (JP), Mick Lauer (EN)

A prince who captures Fushi and wants to help them on their journey of defeating the Nokkers.

A Father to His Men: Despite his eccentric behavior, Bon is loved by everyone in his kingdom, especially those who serve him. As Iris points out, this is because Bon loves and cares about everyone else.
Affectionate Nickname/Only Known by Their Nickname: He prefers that others call him Bon, even his soldiers and servants.
Almighty Janitor: He becomes a literal school janitor so that he can find work and watch over Fushi in the Modern Era. And he still has his fighting skills with him.
Arc Hero: For the Uralis arc.
Badass in a Nice Suit: He wears a fancy business suit in the Modern Era.
For Your Own Good: This is Bon's excuse for hiding from Fushi his power to revive the dead.
Heroic Sacrifice: After Kahaku's Nokker absorbs all of Fushi's vessels, leaving only his original sphere shape, Bon decides to stab himself, hoping that his death will give Fushi a vessel so he can return and save everyone from the Nokkers. Fortunately, it worked and, thanks to Bon's ability to see spirits, Fushi was able to see his companions and remember them without having to recover their forms from the Nokkers, allowing him to revive all if them and leading Fushi to have a Heroic Second Wind, giving him the strength to force the Nokkers out of Renril.
I Did What I Had to Do: He invokes this trope when Kahaku called out Bon for hiding from Fushi his power to revive the dead, and still using his ability to constantly revive Kai, Messar and Hairo, which in addition to deceiving Fushi that the three are immortal warriors, imposes on them the burden of constantly being revived and killed while the war on Renril lasted, which in Kahaku's words is a Fate Worse than Death. Although Bon defends his actions, the decision to hide it from Fushi would lead the immortal to lose trust in Bon at a critical time in the war against the Nokkers. See Nice Job Breaking It, Hero below.
Impaled with Extreme Prejudice: He purposefully kills himself to give Fushi another form to use in order to fight off the Nokkers.
Inadequate Inheritor: He's the eldest son, but his younger brother Prince Torta was made heir apparent by their father. This primarily motivates Bon to prove to his father that he's the worthier king between them for most of his story.
I See Dead People: He apparently has the ability to see ghosts or spirits, which led his mother to fear that he was being possessed and, to this day, she has him take exorcising medicine. This was how he was able to know how to spot Fushi, as Tonari visited Bon, she told him to look for an owl followed by the large shape of a bear, then he will know that it's Fushi. When Fushi enters the city, Bon can see the ghosts of the people that Fushi carries. He even converses with two ghosts who are loyal to him even in the Modern era and briefly talked to March's ghost in the past as he places the doll near her.
Manchild: He acts like this a lot, given his royal upbringing and sometimes lashes out in a childish manner. As the Nokkers slowly start to become a bigger threat, he drops most of this attitude and becomes a surprisingly capable leader.
Nice Job Breaking It, Hero: While Bon's intentions are good, hiding from Fushi his power to revive the dead is still a betrayal of his trust, and keep using his power to constantly revive Kai, Hairo and Messar and hoping he wouldn't question anything until the end of the war backfired as eventually Fushi began to suspect that he was being deceived by Bon, aggravating the immortal's physical and mental fatigue. Ironically, when Fushi realized that he could bring March, Gugu and the others back to life, he have a Heroic Second Wind and managed to win the battle against the Nokkers. This means that Bon accidentally almost caused the heroes' defeat because of his secrecy.
No Good Deed Goes Unpunished: In a sense. When Bon discovered his father's will and how it bequeathed the throne to his younger brother, he demanded the reason for him being passed over and his father responded by asking him what he used his allowance on. Bon responded that he spent it on birthday gifts for his sister and mother, with his father retorting that his brother donated his allowance to an orphanage and spent it on hospital repairs. In other words, he did a good deed by being a good son who bought his family luxurious gifts, but he, at least in his father's eyes, was performing the wrong good by not extending this level of generosity to the commonfolk.
Overly Long Name: Bonchien Nicoli La Tastypeach Uralius. Befitting, since he's a royal prince.
Sheltered Aristocrat: He's a prince who's still very much a brat and can be selfish, but he's loved and cherished by everyone in his kingdom. Even the ghosts who became his friends do genuinely care for Bon.
Spoiled Sweet: Although Bon is eccentric, and may even be shallow and selfish at times, he is benevolent and compassionate, with soldiers and servants genuinely liking him and obeying him out of love for the prince.
Thanatos Gambit: After all of Fushi's other forms have been taken by the Nokkers, Bon decides to kill himself to hopefully give Fushi a chance to revive in his body and counter-attack. It worked
What the Hell, Hero?: Kahaku called out Bon for hiding from Fushi his ability to revive the dead. Although Bon justified that it was to protect Fushi, part of that was also his self-interest not to be abandoned by him, something Bon himself admit.

Eko

Voiced by: Ryō Hirohashi (JP)

Eko is a young girl that Fushi rescues. She also has the strange ability to share her thoughts and memories with Fushi when he touches the pot she carries.

Cute Mute: Eko never says a word, but she communicates with Fushi through her clay pot.
Bungled Suicide: During the war with the Nokkers, she attempts to kill herself by falling off a roof since her arm was infected by Kahaku's Nokker, but it prevents her from going through with it. A revived Kai manages to save her.
Little Miss Badass: During the Nokker attack on Renril, she gives herself a haircut and wields a sword in preparation for battle. We don’t see much of her fighting, but its implied that she kept up pretty well with the others (who are trained warriors, mind you), judging by how long she survived.
She Cleans Up Nicely: When Fushi first meets her, she's covered from head to toe in dirt and filth, with only her eyes visible. After he takes her into his care, he cleans her up and gives her clothes to wear, revealing a thin girl with big cat-like eyes and long wavy hair.

Kai Renald Roulle

Voiced by: Yasuyuki Kase (JP)

One of the three allies Bon chose for Fushi as insurance in the event that he no longer had vessels. He is a Uralis soldier, loyal to Bon and his family.

AbusiveParents: As his grandmother's health deteriorated, his father took his frustration out on Kai, beating him to the point that he genuinely wanted to die.
The Blacksmith: His father was a blacksmith, and he learned how to forge swords during his childhood.
Born in the Wrong Century: More like revived in the wrong century. His talent as a blacksmith and skill at forging swords would certainly be appreciated in the period he was born, but in the modern world such weapons are not so necessary, and as a result Kai was arrested for forging blades without permission.
Life Will Kill You: Kai admits in the Distant Future arc that he has a hereditary disease that is often the cause of his deaths. Feeling that it's a dull and anti-climactic way to go, he just watches from the sidelines and doesn't participate in the discussion whenever the others compete with each other over who met their ends in the "coolest" or most dramatic ways.
Nice Guy: Is genuinely kind and helpful towards Fushi when they first meet and continues to be a helpful ally in the modern age.
Not What It Looks Like: His resurrection in the Modern Era has him brought back with his sword, which caused him to get accidentally arrested before getting bailed out by Bon's royal family.
True Companions: Agrees with Hairo that he and Messar live up to this.

Hairo Ruch

Voiced by: Kaito Ishikawa (JP)

One of the three allies Bon chose for Fushi as insurance in the event that he no longer had vessels. He is a former soldier of the Benett Church's army.

Blessed with Suck: Downplayed, but definitely present. Not being able to feel pain has advantages, but it definitely caused problems for Hairo in the medieval era he lived in. Because of his immunity to pain, Hairo repeatedly caused injuries to himself during his childhood without realizing it and he was subjected to what would be torture on anyone else by the Benett Church, who believed he was possessed by a demon.
Bad Guys Do the Dirty Work: Invoked by Hairo to give March a Mercy Kill with poison. If Fushi ever questioned him, Hairo says he could claim that he didn't understand the pain of people's hearts.
False Teeth Tomfoolery: Despite being young, Hairo reveals that he actually uses prosthetic teeth. That is because the Bennett Church extracted all his teeth during his childhood to test the limits of his resistance to pain.
Feel No Pain: Fushi notices and Hairo confirms this, implying that he was born without the ability to feel any pain.
Heel–Face Turn: Technically, for being part of the Benett Church, Hairo is one of Fushi's enemies. That said, he does not share the church's fanaticism, and due to his traumatic childhood, he was waiting for the opportunity to escape the Church, which came when Bon made him an offer to be one of Fushi's vessels.
Pretty Boy: Certainly passes as attractive. When Doll meets him, she immediately tries to flirt with him.
True Companions: Sees himself, Kai and Messar as this. Messar tries to scoff at them and claim they weren't, but he does seem to be glad they're by his side.

Messar Robin Bastar

Voiced by: Eiji Miyashita (JP)

One of the three allies Bon chose for Fushi as insurance in the event that he no longer had vessels.

Drowning My Sorrows: It is revealed that Messar met his end due to the neglect of his own health, mainly drinking too much. It is implied that this was his way of dealing with the death of Alme. When revived in the new era, this bad habit remained, making Hairo warn Messar that he is on the same path of self-destruction.
The Gambling Addict: Wasted his life away by drinking and gambling. Even in the modern age, he wasted most of his money on buying alcohol and betting on horses.
Heroic Bastard: Messar is the illegitimate son of the king of Renril, and therefore he has no right to the throne. That said, although he is aggressive and rude, he is a good person who genuinely loves and seeks to protect Alme, his half sister.
Incest Subtext: He and the Princess Alme are rather close. He is determined to stay close to her to protect her, but does not reveal that they are siblings, which led her to believe that he wanted to marry her. Fushi, through his ability to feel the feelings of others, confirms that they both love each other.
Jerk with a Heart of Gold: Although Messar is callous and rude, his heart is in the right place and his main goal is to protect Alme, his half sister.
Kavorka Man: Messar has messy hair, piercings, and is often drunk, as well as being rude and offensive. However, it is undeniable that he is the biggest Chick Magnet in the series.
Star-Crossed Lovers: With Princess Alme, who is his half sister. The fact that Fushi saw Love Bubbles around them strongly indicates that they both loved each other romantically, but because Messar knew their parentage, he decided to keep their relationship platonic because of it.

The Doll

https://static.tvtropes.org/pmwiki/pub/images/doll_manga.jpg

The Doll is a Renril Doll in the Future era and has no memories of its past. It wants to become human but requires stars, and is trying to gain stars by hunting the immortals.

Ambiguously Human: Due to current technology allowing humans to freely shape-shift, many people who encounter her assume that she is a human who is trapped in doll form for some reason, but the fact that she has no ID chip, which is mandatory for humans to shapeshift in the Future era, would mean she is a doll after all. However, the technology Eko uses to communicate confirms that she has brainwaves, implying that she is not a robot but a living being.
Become a Real Boy: She has no memories of her past and the only thing she remembers is that she wanted to become human.
If You're So Evil, Eat This Kitten!: After being captured by independent hunters along with Kai and Eko, the soldiers order her to torture Fushi's friends so that they reveal the location of the other immortals, under the condition that after that they would take her to Kaibara and she could fulfill her dream to become human. After some internal struggle, she decides to try to save them and shoots the hunters.
Super-Strength: She managed to lift a wagon by herself to free Kani. She is also able to pack a powerful punch despite her small size.

Friends and Allies

Nameless Boy

Voiced by: Reiji Kawashima (JP), Jacob Hopkins (EN)

The first human Fushi meets, who mistakes the immortal being as his wolf Joaan who he believed got lost in the snowstorm. He is extremely optimistic despite his circumstances, and has a perpetual smile on his face.

Break the Cutie: As the Nameless Boy continues on towards the mountains, the stones with arrow markings keep his hopes up. However, once he reaches the last stone with an "X" crossing it out he looks up to see wagons covered in snow and multiple graves. He tries to think optimistically, saying that this must mean the people made it over the mountain, but slowly begins to cry when he knows that they may not be able to make it across. Once he and Fushi return back to his hut he begins to weep throughout the night.
The Determinator: The boy notes that this trait is what makes him cool.
Go Mad from the Isolation: Subverted. He doesn't go full crazy, but clearly being alone with only himself and pet wolf Joaan for company is doing a lot on his psyche as a whole.
I Will Wait for You: The reason why he never travels too far from his hut and has bells around his hut to alert him if his family had returned. This ends up being in vain because he later finds out they're all dead but still decides to wait back in his cottage. Although it was likely because he was slowly succumbing to his fever.
Last Words: He asks Fushi, "Don't forget me" as he slowly succumbs to his fever and dies.
Major Injury Underreaction: After the boy falls into a river under the snow, he laughs it off, only to notice that his leg has a severe wound on it. His reaction is only mildly surprised, but later he laughs it off, even as he notices his wound getting worse.
Minor Living Alone: The Nameless Boy lives all by himself in the middle of nowhere surrounded by broken-down houses his relatives used to live in. He says he actually wanted to travel with his tribe, but they insisted he take care of his elders, which he did until they all died and he was left alone with Joaan to fend for himself.
No Name Given: Fushi never hears the boy's name, and before he says his name to the people in his afterlife, it's cut off.
Passed in Their Sleep: How the boy eventually goes.
Perpetual Smiler: He's never seen without a smile on his face when Fushi is around him. He probably does this to cope with his loneliness.
Plot-Triggering Death: Although Fushi may not have understood the boy's wishes clearly, his death is what gives Fushi his current form and desire to meet new people and experience new things.
The Pollyanna: Is determined to remain near his hut to wait for his family to return. He continues to wait even after his grandparents die and his family hasn't come back in five years.
The Promise: He tells Fushi to never forget about him as he slowly succumbs to his fever and dies in his sleep.
Small Role, Big Impact: The boy dies in the first chapter, but he is notably the first human form that Fushi takes and often defaults to. He also defined Fushi's life with his desire to experience new things and meet new people.
Thinking Out Loud: The boy does this a lot, probably to make up for the loneliness he feels and carries a conversation with Fushi.

Joaan

The Nameless Boy's pet Arctic wolf. He was the first animal whose form Fushi took.

Lightning Bruiser: Downplayed. As a wolf, he's fast, agile, and armed with fangs and claws, making him well-suited for battle and Fushi often uses his form for combat but he remains a mere wolf, being relatively fragile compared to Fushi's other vessels and if it weren't for the immortal's regenerative power it would qualify more as a Fragile Speedster.
Plot-Triggering Death: He essentially starts Fushi's journey by dying near him, giving Fushi his first animal form and with it, the ability to move on his own.
Small Role, Big Impact: He technically only appears at the beginning of the series, where he quickly dies near Fushi. In doing so, he gives Fushi his first animal form, giving Fushi the ability to move for the first time.

Parona

Voiced by: Aya Uchida (JP), Valeria Rodriguez (EN)

A girl who lives in March's village of Ninanna, and loves the girl like a little sister. She's happy to indulge March in their game of house. While she carries a bow, she's not a real good shot.

Action Girl: Despite her poor aiming skills with a bow, she has plenty of other talents that she uses to protect March and get out of bad situations.
Aloof Archer: Her main weapon is a bow, even though she's not the best shot. She's also fairly independent and prefers to do things on her own.
Big Brother Instinct: Or in this case, sister. She's very protective of March, possibly due to the fact that, when Parona was forced out of her village not, knowing where her big sister was, she comes upon her corpse. She realizes the game of hide-and-seek they were playing was in order to keep her safe.
Children Are Innocent: Played a game of hide and seek with her sister when she was around March's age not knowing the reason why. When she doesn't show up, she wanders around to find her, and comes upon her sister's corpse when the villagers who were chasing after them run by.
Combat Pragmatist: When tricking one of Hayase's men, she uses a mop that she used for cleaning and stabs him in the chest, revealing she had sharpened one end when they weren't paying attention.
Conveniently an Orphan: She lives near March's village but has no family there. She was chased out of her original village with her elder sister sacrificing herself to keep her alive.
Cool Big Sis: March sees Parona as this, and Parona thinks this of her big sister who died to protect her.
Cruel and Unusual Death: Hayase initially tortures her, but then decides to take off her face as payment for ruining hers. Hayase then tells Fushi how hard of time she was having taking off Parona's face and how she decided to just kill her.
Dark and Troubled Past: Parona's sister tricked her into hiding for a week, leaving food and supplies for her to survive during that time. Upon returning to the village, Parona found that her sister had been sacrificed to Oniguma, and she was banished from the village for her "cowardice", finding what was left of her sister's corpse shortly thereafter. After all this trauma, it's no surprise that Parona abhors the ritual of sacrifice, which she considers an evil tradition that should disappear.
Desperately Looking for a Purpose in Life: She doesn't have much going for her and finds solace and purpose in life in looking after March. When she ends up dying trying to protect her, Parona nearly goes insane with grief and attempts to take her life to join March in death.
Escape Artist: Apparently keeps a small serrated knife hidden in her shoe so she can use to saw out of ropes if needed.
Interrupted Suicide: She tries to commit suicide after March is killed, but is stopped by Fushi.
Killed Offscreen: Fushi takes on her form during his gladiator match and quickly realizes that Parona either died some time ago or just now. It's later revealed that Hayase took her face and killed her in the process. Averted in the anime where we see how Hayase killed her in a brief flashback.
The Lost Lenore: Fushi still takes on her form on occasions, but has not brought her back to Modern day. Even March has taken notice of this and cries in Fushi's arms while he's in Parona's form that she misses Parona. It could be implied that one of Mizuha's close friends is actually Parona's reincarnation since they do share some similarities.
Motherly Side Plait: She wears her hair like this and acts almost like a big sister to March. She also ends up dying by Hayase's hand, who killed her by tearing her face off.
Off with Her Head!: How Hayase killed her in the anime, which is much, much more merciful than what Hayase originally did to her in the manga.
Playing House: She does this with March playing the role of the "husband". She even creates little dolls for March as their "children" and seems content with being around the little girl.
The Pollyanna: Acts this way around March in order to keep the girl innocent of the dangers they're actually facing.
Pyrrhic Victory: She manages to stall Hayase from going after Fushi, but doesn't manage to kill her as she frustratingly laments she actually missed when she hit her hand instead of her head. This leads to Hayase killing her later on and even wearing bits of her face.
- This is downplayed, as she also wanted to ensure that the sacrifice ritual would never happen again. Bonus of volume 2 says that the people of Ninanna, upon seeing Fushi in the form of Oniguma and then transforming into a human and a wolf before departing, believed that he was the legendary bear and Parona used the opportunity to tell everyone that there was no longer any reason for the ritual to be carried out, achieving one of her goals.
Raven Hair, Ivory Skin: Played with. It was after her death, and Fushi taking her form that people commented on her looks. Tonari almost hasa crushgirl on Parona when Fushi turns into her and comments about what a beautiful pale skin and luscious hair she has.
Screw the Rules, I'm Doing What's Right!: Despite the beliefs and traditions of the village, Parona refuses to let March be sacrificed and tells her it's okay if she wants to grow up and become an adult.
Shapeshifter Default Form: When needing to present as a girl, Fushi usually choses Parona's form.
She Cleans Up Nicely: When Fushi takes on her form and Bon has her dressed and cleaned up. Kahaku's face flushes even deeper when he sees Fushi all dolled up.
Stepford Smiler: She does this to cope with the cruel world she lives in, and especially so around March, to protect the little girl's innocence.
Unkempt Beauty: While she's not entirely unkept, she mainly lives out in the wilderness but still draws the attention of some of the male villagers, and even gets Kahaku's attention when Fushi uses her form.

Rean Cropp

Voiced by: Manaka Iwami (JP), Cherami Leigh (EN)

https://static.tvtropes.org/pmwiki/pub/images/rean_9.png

A noble girl who Gugu has a crush on, and she frequently goes to the shop to see Fushi and teach him. Rean wishes for nothing more than to be free of her parents' strict control of her life and be allowed to make her own decisions.

Arranged Marriage: Rean has a schedule to take place when she turns sixteen, but she admits to Fushi that she hates the idea of marrying someone she doesn't love, declaring that she intends to get a boyfriend to introduce to her parents on her birthday and call off the engagement.
Hair of Gold, Heart of Gold: She's shown to be blonde in the colored illustrations, and she's very nice and kind.
Good Scars, Evil Scars: She has a small scar on her arm that she exaggerates to be embarrassing compared to Gugu's face. He hotly points out that her scar is minute compared to his facial disfigurement, especially since no one can really see it.
I Will Wait for You: Tells Gugu, who she knows is Fushi, that she'll wait for his return so they can pick flowers together like he promised. Because of that, she never married.
Killed Offscreen: She likely died during Fushi's travels as he is able to take on her form later on.
Last Kiss: Rean gives this to Gugu as he protects her from the falling rubble of her house.
Lonely Rich Kid: Her parents don't allow her to go outside alone, and shelter her at home. Whenever she does something, her parents immediately divulge the activity to the extreme. She wishes to be allowed to make mistakes and get hurt like normal people.
Love Confession: She tells this to Gugu, who's actually Fushi in Gugu's form, after she wakes up after the monsters attack.
Maintain the Lie: Rean knows that Fushi took on Gugu's form, which meant that Gugu was dead, but she said nothing.
The Mourning After: She never married because she was waiting for her boyfriend to return, and since she knew Gugu had died, it is clear that she was mourning Gugu all her life.
Nice Girl: Despite being a Sheltered Aristocrat, Rena is nothing but a very polite and friendly young girl.
Runaway Hideaway: Rean considers the old medicine man's place her second home.
Uptown Girl: Rean is a rich and noble girl while Gugu is a disfigured lower-class boy.In the end, what stopped their relationship from working out was not the class difference between the but the tragic death of Gugu.

Booze Man

Booze Man is an old man who saved Gugu's life and is also Pioran's lover.

For Science!: The reason why he put alcohol in Gugu's stomach. When Gugu confronts him, the Booze Man says he was curious to see how alcohol brewed inside a human belly would turn out, and tells Gugu not to worry, he wouldn't die from it. Feeling betrayed and violated, Gugu runs away from home and both Pioran and Rean criticize him for it.
Gadgeteer Genius: Definitely. The Booze Man is the one who built Gugu's new mask with an igniter, which combined with the alcohol inside his stomach makes him a powerful Booze Flamethrower.
Good Samaritan: Downplayed. If not for him, Gugu would certainly have died with his head crushed under the log. That said, the Booze Man took the chance to experiment on him out of sheer curiosity, with no respect or consideration for how Gugu would feel about it, which led Gugu to run away when he found out and took a while to forgive him for it.
No Name Given: His name is never said, which is why he is simply called "Booze Man".
Parental Substitute: He is this to Gugu. Similar to the way Pioran considers Fushi her grandson, the Booze Man tells Gugu that he thinks of him as his own grandson.

Shin

Voiced by: Atsushi Abe (JP)

Shin is a young man from Takunaha and Gugu's older brother.

The Atoner: Years after abandoning Gugu, Shin, now a successful trader, meets with his brother trying to fix the relationship and return to live together as a family, but Gugu refuses, preferring to stay with his Family of Choice. Resigned, Shin then promises to be there to help him the day he needs because that is the only way for him to prove that he is his brother.
Broken Tears: He's absolutely heartbroken and weeping heavily when he finds Gugu's corpse amongst the ruins of Rean's house.
Broken Pedestal: Shin abandoned Gugu and took all the money they had collected, leaving his younger brother to survive on his own. Of course, Gugu respects him a lot less after that.
Disappointing Older Sibling: To Gugu. After losing their jobs, Shin abandoned him and took all the money they had, leaving Gugu to survive alone. Years later, Shin tries to make up with Gugu and asks he to return to live together, he refuses preferring to be together with Fushi and the others.
Promotion to Parent: Deconstructed. Having no parents, it was up to Shin to take care of Gugu alone, which he did for years but he was not emotionally mature to handle that amount of responsibility, and even though he cared a lot for Gugu, he couldn't take it anymore and abandoned his younger brother, stealing all the money they had earned together.
Rejected Apology: When Shin reappears years after abandoning him trying to make up for having abandoned him and proposing that they live together again, Gugu makes it clear that he does not forgive him. However, in Gugu's vision of Paradise, he and Shin made peace, indicating that Gugu wished to have forgiven his brother.

Todo Iris

Voiced by: Akeno Watanabe (JP)

Prince Bon's servant and human seat, they do just about everything for the prince.

Forgotten First Meeting: Slightly subverted. Bon's first crush was a girl who made a handkerchief that he cherishes, but due to Todo's increased weight, he doesn't realize she's the same girl and thinks she's a male.
Happily Married: Gets married to Bon later and watches over him at his bedside as he starts to pass away from old age.
Undying Loyalty: Todo will do just about anything for Bon, whether that be serving as a human seat, or sifting through piles of shit to retrieve Bon's precious handkerchief. Fushi wonders what they see in Bon, and Todo can only meekly reply. Then it's revealed that Todo is Iris, the girl who Bon had met in the past.
You Are Fat: Because their father is a baker, they were given a lot of food to eat, causing them to gain a lot of weight. So much that Bon didn't recognize her as the girl who he met as a child and was convinced was a ghost.

Princess Alme

The princess and heir to the throne of Renril.

Mysterious Veil: She was educated that the princess needs to always put a veil over her face, meaning that she must put a veil over her heart. That is why she only reveals her face to people who have earned her trust.
Star-Crossed Lovers: Although she and Messar are half-siblings and she doesn't know that, it is strongly implied that Alme loved Messar romantically. After discovering that she and Messar are siblings, Alme is killed by the Nokkers, and not even Fushi can revive her. Bon says that she has already left for Paradise and she probably chose the Nostalgia Heaven because she and Messar could be a couple there despite being siblings.
Youngest Child Wins: Due to Renril's law, the king's youngest heir is the one who inherits the throne which is why Alme is expected to become queen despite having older brothers.

Yuki Aoki

A character of the Modern Era. He is the vice president of the Occult Club and one of new Fushi's friends.

All-Loving Hero: Genuinely believes that it is possible to reach an understanding with the Nokkers so that Mizuha comes back and everyone is happy.
Cannot Keep a Secret: He sucks at keeping secrets, often swearing not to tell anyone on one panel, but happily telling everyone in the very next one. He almost immediately revealed to Fushi's companions that the Nokkers still existed despite vowing to keep secrecy, and the only reason he didn't spill the beans was because the immortal was right behind him.
Dogged Nice Guy: He's in love with Mizuha. Unfortunately for him, she only has eyes for Fushi.
I Want My Beloved to Be Happy: Despite being in love with Mizuha, when she asks him for advice on how to deal with her feelings for Fushi, who says he's not interested in her and doesn't want to fall in love with anyone, Yuki sincerely replies that he would pretend he didn't hear if it were him, motivating Mizuha to keep trying to make Fushi fall in love with her.
Parental Abandonment: Downplayed. His parents are alive and well, but because they are archaeologists, they work overseas, which is why his grandfather takes care of him and his sister. Despite that, a video call showed that they are kind and maintain regular contact with their family.
Nice Guy: Although he was pushy to convince Fushi to come to his home, even pretending to be ill so that he would stay to help him, he is genuinely a good person who helped Fushi adapt to the new world.

Izumi

Izumi is the mother of one of the main characters of the Peaceful World Arc, Mizuha.

Abusive Parents: At first glance, Izumi seems like a vain person and a bad mother towards Mizuha. She seems to only be interested in her daughter's successes and pushes her to master one thing after another, without regard to her feelings. Despite this, she loves Mizuha and her treatment stems from trying to keep Mizuha away from the Defense Corps and part of that was because of the Nokker inside her was making her forgetful, but Izumi herself came to admit that she was a toxic mother to Mizuha. It hurts even more when the story revealed that Izumi's father was also quite abusive to her as well because he wanted her to become a "perfect mother" to the future 18th successor of Hayase.
Armor-Piercing Question: Years ago, her husband points out that she was pushing their daugther too much and that she needs less lessons and more time to make friends. Izumi tries to defend her actions, saying that she won't be raising the 18th successor and that she wasn't doing anything weird with Mizuha, but her husband then asks if she ever cared about Mizuha's well being, shocking her and causing the Nokker inside her to take control of her body:
Mizuha's Father: Have you ever done something for Mizuha's own sake?!
Determinator: She is determined to raise Mizuha well to ensure she doesn't become the 18th successor.
Doting Parent: She dotes on Mizuha, whom she considers her reason for living. Ironically, she is also a rather strict Education Mama who ended up pushing her daughter too hard, becoming an Abusive Parents in the process.
Dramatic Irony: To prevent Mizuha from becoming the 18th successor, Izumi severed relations with her father and withdrew from his cult. However, by pressuring Mizuha to be the best at everything she did, Izumi ended up chiseling Mizuha away from her own life and subjecting her daugther to another type of abusive treatment, which ended up pushing Mizuha to her grandfather and the Nokkers.
Education Mama: Justified and deconstructed. Because she didn't want Mizuha to become the 18th successor, Izumi made her daugther excel in every sport, activity and subject so that she can prove to her father and the Guardians that she can raise Mizuha on her own and be a perfect mother, but the constant pressure eventually led Mizuha to believe that she is nothing but a trophy to her.
Fatal Flaw: Her determination to raise Mizuha well and prevent her from being Hayase's 18th successor is ironically her flaw as mother. To achieve this Izumi pressured Mizuha to try everything and become the best at them, which despite having made her daughter The Ace, also made her arrogant, with problems empathizing with others, depriving her of social life and friends and causing Mizuha to resent her.
Freudian Excuse: The reasons behind her abusive treatment of Mizuha are later revealed. Izumi really loved her daugther but the unfortunate circumstances of her life led her to be a toxic mother to Mizuha: to ensure that her daughter wouldn't go through the same abusive treatment she had, Izumi tried to put as much distance as possible from her father and his cult to prevent Mizuha from becoming Hayase's 18th successor. However, upon discovering that the husband she chose was actualy a member of the said cult and was deceived her all along and not having the courage to divorce for Mizuha's sake, Izumi decided to push Mizuha more and more, trying to raise her well and away from the cult's influence, but also preventing her from socializing and making friends to the point that Izumi was raising Mizuha more to prevent her from becoming the 18th successor than for Mizuha's own sake.
Hidden Depths: At first, Izumi comes across as a combination of Control Freak and Education Mama towards Mizuha. However, with the revelation that she is aware of Fushi's existence and his companions, it is implied that part of her treatment of Mizuha was to keep her away and safe from the Defense Corps.
Parents as People: She dearly loved her daughter but put a lot of pressure on Mizuha to prevent her from becoming Hayase’s 18th successor, to the point that Mizuha began to feel that she was a Trophy Child. Izumi admits that she was wrong for doing so because she was unintentionally abusive to her.
My God, What Have I Done?: When Fushi tries to destroy the Nokker inside Izumi's body in order to revive her, Mizuha begs him not to do so. Fushi asks why she is protecting the false mother and Mizuha says that her new mother doesn’t treat her like a trophy, doesn’t pressure her and makes her happy, and that she’s more fit to be her mother, begging him not to hurt those who important to her. Unbeknownst to Mizuha, Izumi's fye watches her daughter's statement and can only cry when faced with the consequences of her abuse.
You're Not My Father: In relation to her father. Because her father led a cult that worshiped Hayase's Nokker and sought to try to control her entire life, including trying to force her into an Arranged Marriage, and even deceiving her about the husband she chose, who was a covert member of said religion, besides seeking to make her daughter the 18th successor to Hayase, Izumi cut all ties to her father and forbid him from interacting with Mizuha in any way, even going as far as to destroy the letters he sends her.

Hirotoshi

Hirotoshi is a jobless Otaku who stays with his father in the Modern Era. After meeting his father's new fiancee, he becomes an older step-brother for the fiancee's daughter, Mimori. However, the sudden erratic behavior of Mimori after an incident at the daycare caused him to get involved in the new problems Fushi and his allies face.

Big Brother Instinct: Becoming the older step-sibling to Mimori made him become a little more responsible. After seeing the changes in her behavior, he's determined to bring back the "Real Mimori".
Determinator: He's very determined to save Mimori from the Nokker that possessed her body. Even when the Mimori Nokker is beating him to a pulp, he still continues on trying to fight off the Nokker.
Fan Disservice: The Mimori Nokker subjugates Hirotoshi to bondage play. He eventually escapes to a park, but his state of panic makes him flash his half-naked body to Fushi, causing Fushi to faint out of fear. Thankfully, Aoki and Bon arrived just in time to help both of them out, with Aoki lending Hirotoshi some clothes.
Foil: To Mimori's "normal" parents. Hirotoshi is an otaku with lolita complex, jobless and would be judged as a scum in any society. Yet, when push comes to shove, it is Hirotoshi who proves to be a caring brother to Mimori while her "normal" parents are too negligent to notice the clear signs that she was depressed to the point of considering suicide (which ended up happening), or to think her sudden personality change strange.
I Know Mortal Kombat: When fighinting the Mimori Nokker, he refers to himself as a Hero from the videogames he plays. He even tries to use Fushi's sword to fight off the Nokker, with little success due to his inexperience, unfortuntately.
Otaku: He's an accurate example of this trope, though he has redeeming features, such as being a Determinator, that prevent him from being a complete shut-in.

Mimori

A young child who stays with her mother in the Modern Era. After her mother decides to stay with her new husband, she becomes a step-sister to her step-father's son, Hirotoshi. While she's mostly shy, she does have a kind heart. But an incident at the daycare had caused Mimori's personality to change drastically and called the attention of Fushi and his allies to investigate.

Abusive Parents: She reveals to Bon that her mother was actually very negligent towards her and only cared about finding a new lover. This abuse is what caused her to be Driven to Suicide and allowed the Nokker to possess her body. After meeting Fushi again post-resurrection, Mimori has come to terms with her mother and is able to get along with her like she used to.
Back from the Dead: While Fushi and Hirotoshi weren't able to retrieve Mimori's original body after her Nokker was destroyed, Fushi creates a new body for her and Bon's communication with her spirit allowed her to finally come back to life.
Nice Girl: Although a little shy, she's actually a good kid at heart. Her overall personality is what differentiates her from the Nokker that possessed her body.
Worth Living For: Mimori's spirit cannot return to her body if she doesn't have the will to live again. With words of encouragement from Bon, she realizes that she didn't want to commit suicide after all and only wished for a loving and caring family to be with. After defeating the Nokker, Fushi creates a new body and Mimori is successfully resurrected and happy to be with her older step-brother Hirotoshi.

Sumika

A girl who watches over a boy named Satoru (who is actually The Beholder in human form). She acts as a Cool Big Sis to Satoru and other children she watches over.

Bully Hunter: Not only is she a Cool Big Sis, but she's serious about defending the children she watches over. A misunderstanding between her and Fushi causes her to think Fushi is a bully, ensuing hilarious results.
Cool Big Sis: She acts as a big sister figure to the children she watches over. She even tells Fushi and his friends that she refers to herself as "Aneki", meaning "older sister".
Entertainingly Wrong: After interacting with Satoru and seeing how he reacted to basic things, such as eating and bathing as if he had never had one before, she concludes that he is a poor boy who grew up without love, hence why she decided to be Cool Big Sis for him and fill his life with love. Fushi, knowing that Satoru is actually the Beholder and that he has always been an introverted Jerkass who is trying to Become a Real Boy, laughs at how mistaken Sumika is about Satoru.
Ms. Fanservice: Her overall outfit consists of shorts and a tank top underneath her jacket that exposes her breasts.
Unskilled, but Strong: Finesse isn't necessary for her. All she needs to do is hit someone really hard. Fushi unfortunately finds out the hard way.

Funa

A highschool student and classmate in Fushi and Mizuha's class. After helping in defeating the Mimori's Nokker, she becomes a person of interest to Fushi and his investigation into the Modern Era problems.

The Bully: She is part of the group that subjects Mizuha to bullying and badmouthing her a lot, something herself recognizes and admits that maybe she wasn't worth keeping alive. That said, she's not wrong to point out that she didn't deserve to be killed for it and it is implied that she decided to leave the group after being revived.
Brutal Honesty: Her classmates point out that she doesn't hide her thoughts and opinions that cross her head, which she confirms when she is revived by Fushi.
Disproportionate Retribution: The reason why Funa gets a naginata through her abdomen is because the Nokker in Mizuha felt her distress after seeing Fushi and Funa together (although he was only interrogating Funa's Nokker). So Mizuha's Nokker possessed her to attack Funa and satisfy Mizuha from her brief jealously.
Dead All Along: The real Funa had already committed suicide due to a fallout between her friends. The current Funa that is shown is actually a Nokker possessing her body. But in a later twist of events, Funa's spirit was revealed to have been wandering along with Izumi and the other spirits. This allowed Fushi, with the help of Bon, to ressurect the real Funa since he needed her help in interrogating the Nokker within Mizuha.
Fan Disservice: When Fushi transforms into a mosquito to spy on Funa, the angle of the perspective is shown from down up, giving viewers a glimpse of Funa's underwear in her loose gym shorts. After this, a Nokker-possessed Mizuha appears, only to greet Funa with a naginata to her abdomen with another shot of her panties shown.
Jerkass Has a Point: Funa acknowledges that she bullied Mizuha at school but also point outs she didn't deserve to be killed for it, which in fact was a Disproportionate Retribution motivated by Mizuha's jealousy over Fushi and not getting revenge for the bullying.
Good All Along: Not the Nokker, but the real Funa is. And thanks to Fushi resurrecting her, she's now considered an ally in helping Fushi stop the Nokkers.
Sophisticated as Hell: Once the real Funa arrives after her resurrection, Funa gives the Mizuha's Nokker a piece of her mind and let's the Nokker know that she was not happy about the events that transpired.

The Guardians

The Defense Corps (守護団), also known as The Guardians, is a group dedicated to not only protecting Fushi from Nokkers' attacks but protecting citizens as well.

In General

Bodyguarding a Badass: The Guardians are this to Fushi.
Body Horror: The Nokker in each of Hayase's descendant's arm can warp, stretch and change shape, utilizing itself as a weapon.
Cult: What they have become in the modern era. Formerly a military force that had the objective of protecting Fushi, nowadays they are a cult that await the return of Hayase's Nokker to return to their mission as Guardians.
Family Theme Naming: The members of the Hayase's bloodline have water-themed names like Hayase (waterfall), her grandaugther Hisame (freezing rain), and her descendants Kahaku (ocean), Izumi (fountain) and Mizuha (water).
Reincarnation: All of the Guardians are this of Hayase.
Reincarnation Romance: The Guardians' secret mission is to carry out Hayase's will and get one of Hayase's reincarnations to have children with Fushi. So far they have failed.
Sins Of Our Mothers: The source of much of the bitterness between Fushi and Hayase's successors. Because of the atrocities Hayase committed against him, for centuries Fushi is unable to feel comfortable around her descendants even though he knows that none of them are responsible for her crimes (the fact that they have a Nokker inside them definitely doesn't help), and although he tolerates their visits Fushi refuses to become close with any of them. However, after Fushi accepts Kohaku's company to deal with the Church of Bennet and the Nokkers' attacks, over time they become close enough that Fushi considers him a comrade. This ends up creating a complex situation for Fushi when it comes to Mizuha, Hayase's latest successor: despite feeling uncomfortable in returning the love Mizuha feels for him, Fushi seeks to be close to her because of the affection he felt for Kahaku.
Stalker with a Crush: All of Hayase's descendants certainly do come off like this, with Kahaku being a slight exception.
Strong Family Resemblance: All of Hayase's reincarnations have her face, which stunned Fushi the first time he met her descendant.
The Symbiote: Due to Hayase's strong will, she's able to pass down the Nokker to each of her reincarnations. In the Modern Age, the Nokker is small enough that Fushi and the Beholder weren't able to tell it was there and assumed the Nokkers had gone extinct.

Hayase

Voiced by: Mitsuki Saiga (JP), Kira Buckland (EN)

A woman who is the leader of the Guardians, and serves as the antagonist towards Parona and March. After taking a hit in his bear form, her face becomes horribly disfigured and she later kills Parona for her face. She then looks for Fushi around the world, claiming that she is in love with him and wants to bear his children.

Anguished Declaration of Love: When Fushi ask why she killed March and Parona, Hayase says they were trying to steal him from her, declaring that she fell in love when she saw him face the Oniguma. She then tries to offer to teach him love (read: sex) and proposes that he kill her to be together with him, saying that she is stronger than all of Fushi's vessels. All of this only makes Fushi more disgusted and he leaves, telling Hayase to leave him alone, that he hates her and that he wouldn't mind her dying.
Attempted Rape: She tries to rape Fushi while he was unconscious due to poison.
Ax-Crazy: She’s able to put on a Mask of Sanity, but it doesn’t take long for anyone to find out how balls-to-the-wall batshit insane she is.
Dark Action Girl: She is a skilled warrior, managing to defeat Fushi and powerful vessels like Oniguma, Gugu and Parona.
Facial Horror: Her entire face gets scarred due to the bear attacking her and it doesn't get better when she kills Parona by slowly peeling off her face in revenge.
Faux Affably Evil: She comes off as a stern, but well-meaning woman, but when no one’s looking, she’s a vile woman who couldn’t care less for the people she hurts.
Good Scars, Evil Scars: Definitely evil scars. After Fushi retaliated in the form of a bear for killing March, the immortal caused a huge wound in Hayase, with the scar extending from her belly, passing through her chest and reaching much of her face.
Historical Hero Upgrade: After stealing Tonari's diary, Hayase's clan changed the original version so that the Guardians were painted in a very favorable light, narrating that Hayase was Fushi's first guardian and not the Yandere that she really was, conveniently omitting important details such as the fact that Fushi hated her.
Lecherous Licking: She licks Fushi's face whenever she can, and the audience even gets a first-person perspective of her grabbing Fushi and coming at him with an open mouth.
Over-the-Shoulder Carry: After defeating Fushi, she loades him onto her shoulder and carries him over her shoulder to a room for the subsequent Attempted Rape.
Rape Is a Special Kind of Evil: Implied. After the fisherman who saved her life comes to bring her food, she violently pulls him into the hut. It can be inferred that she raped him as she was able to have an offspring who looked for Fushi later on. She also attempted to rape Fushi when the immortal was unconscious.
Shadow Archetype: Hayase serves as this for to all her successors. She has an obsessive love for Fushi that drives her to seek an intimate relationship with him, but Hayase takes it to the extreme to the point that she kills people Fushi loves because she believes they were taking him away from her, which only makes Fushi hate her and try to be as far away from her as possible, while her successors, although they are all romantically attracted to Fushi, they are not as psychotic and bloodthirsty as Hayase was and over time Fushi comes to tolerate them. After accepting the company of Kahaku, Fushi comes to regard him as a friend to the point that in the Modern Era it is Fushi who is approaching Hayase's latest successor, proving that if Hayase hadn't been so bloodthirsty in forcing her feelings on Fushi, maybe she would have been successful in getting close to him.
Stalker with a Crush: She tells Fushi that the reason why she's following him is because she loves him after the day he nearly killed by the Oniguma.
The Symbiote: When Fushi pushes her out at sea to get away from her, a Nokker takes her as its host. However, because of her strong will, she's able to essentially live on in each of her reincarnations.
Unsexy Sadist: Hayase is a beautiful young woman who is extremely domineering towards and possessive of Fushi, who is absolutely horrified and scared of her.
Villainesses Want Heroes: Hayase feels lust for Fushi, to the point that she almost rapes him, and she tries to justify March and Parona's deaths were necessary because they tried to take him away from her.
Would Hurt a Child: Murdered March, Parona, and Gugu, all of whom were not adults. This understandably does not bode well for Fushi.
Yandere: For Fushi. Her "love" is so strong that her descendants pursue Fushi in the hope that he will accept her one day.

Hisame

https://static.tvtropes.org/pmwiki/pub/images/3be37622_9fbf_49a5_84a4_3d296fd3bfc1.jpeg

Voiced by: Tomori Kusunoki (JP), Dawn M. Bennett (EN)

Hayase's grandaughter, a nine-year-old girl who searches for Fushi in order to protect him.

Creepy Child: Mainly due to the Strong Family Resemblance she has to her grandmother.
Fille Fatale: Her goal in finding Fushi was to have children with him. At the age of 9. Luckily, she was naive enough to believe that a couple just needs to sleep together and wish they would have children that she would become pregnant (and Fushi was just as naive about it).
Troubling Unchildlike Behavior: Downplayed. She reveals quite innocently that the Guardians' secret mission is for Hayase's descendants to have a child with Fushi. What makes it worrying is that she is 9 years old, but otherwise seems like a well-adjusted minor.

Kahaku

Voiced by: Mitsuki Saiga (JP), Chris Hackney (EN)

The sixth successor to Hayase's legacy, this time a male. He explains that his mother couldn't give birth to a girl before she died, so they had to make do.

Act of True Love: At the cost of his own life and for Fushi's sake, Kahaku performs one to destroy the Nokker in his left arm and the main town of the Bennett Church with a massive explosion. By this time, Kahaku no longer expected to be loved or even considered a friend by Fushi after everything that happened, but he still decides to sacrifice himself to help the immortal because he loves Fushi.
The Atoner: When the Nokker in his left arm kills Fushi's allies and almost "kills" the immortal himself, Kahaku convinces it to leave Eko's body and return to his body. After that, instead of going back to try being accepted again as an ally of Fushi, Kahaku leaves a letter apologizing for not being able to help him, saying that the Guardians would be at his disposal if needed, then leaving to make a Heroic Sacrifice.
Dramatic Irony: When he and Fushi meet, Kahaku promises that he won't try to seduce him like his ancestors did and that he likes women. However, seeing Fushi in the form of Parona for the first time, he ends up falling in love anyway and after his feelings mature Kahaku decides that he will love Fushi regardless of who he is.
Driven to Suicide: In a combination of this trope and Heroic Sacrifice, Kahaku kills himself in order to destroy the Nokker in his arm and return to Fushi all the vessels it stole.
Dying Declaration of Love: "I love you... Fushi."
Go Out with a Smile: Even in an immense amount of pain, Kahaku still smiles as he thinks of Fushi and falls to the molten metal below.
Heroic Sacrifice: Kahaku, carrying several explosives and pretending to have abandoned his devotion to Fushi, went to the city of Entas and convinced the High Cleric Cyrila of Bennett's Church that he also wanted Fushi dead. Knowing then that he would be killed if he said he was still affiliated with Defense Corps, Kahaku confirms it and is promptly pushed to his death in a blast furnace. Despite the Nokker in his left arm trying to save itself and its host, Kahaku cuts off his left arm, ensuring their deaths, returning several vessels to Fushi and causing a tremendous explosion in Entas, killing High Cleric Cyrila and several members of Bennett Church and declared enemies of Fushi.
Historical Villain Upgrade: Bonus of volume 13 confirms that Kahaku was a victim of this. In the version of the events according to a follower of the Bennet Church, Kahaku maliciously deceived High Cleric Cyrila and pushed him to die in a blast furnace and then exploded himself, causing the destruction of the city of Entas which would be called a cursed city. However, the truth is that Kahaku was pushed by Cyrila to die in the blast furnance (which was Kahaku's plan to make a Heroic Sacrifice from the beginning). Considering that followers of the Bennett Church believe that Cyrila, a Tautological Templar who would Would Hurt a Child, defeated Fushi and saved the world, it is no surprise.
If It's You, It's Okay: Played with a bit. When Kahaku first meets Fushi, he says that he likes women and has no interest in men. Yet later on, he asks Fushi for their hand in marriage (in Parona's form), Parona's body freaks out and is incredibly disgusted at this proposition. Even when Fushi uses his male form, Kahaku claims that he would love him even as a male. However, after a few other forms, Fushi explains to Kahaku that Parona's form was brutally murdered by his predecessor, Hayase, all for wanting to protect March. Kahaku, realizing why Parona's form acted the way she did, gives him a new perspective and he is genuinely apologetic to Fushi for forcing a hug on them.
- He still seems to be very attached to Fushi in his normal form, but chooses to treat them more like a human being and friend. Even in the end when he sacrifices himself to wipe out the church and hopefully the Nokker still in his arm, he declares his love for Fushi as he dies.
Life-or-Limb Decision: Unlike most versions, Kahaku is forced to cut off his left arm in a desperate attempt to prevent the Nokker in his left arm from stealing all of Fushi's vessels. Unfortunately the creature escapes after reducing the immortal to its original sphere shape.
Love at First Sight: He tells Fushi that he likes women and won't try to seduce him like his female ancestors, preferring to be friends. But after getting egged by townsfolk, he suggests Fushi take on a different form. After shuffling through all the female bodies he has, Fushi takes on Parona's form, causing Kahaku to have a Crush Filter around her and a Crush Blush. He even tries to get close to Fushi in Parona's form, constantly finding excuses to touch her.
My Friends... and Zoidberg: A downplayed and justified version. Because Kahaku is Hayase's reincarnation, Fushi is unable to allow himself to be intimate with him because of the atrocities his ancestor committed (at least in the form of Parona). And also, because of the Nokker in his left arm, Fushi and his companions are wary and suspicious of him. That said, Fushi definitely considered Kahaku a friend, and thanks to him, Fushi has gone from despising Hayase’s descendants to wishing the best for them.
My God, What Have I Done?: When he tries to force his love onto Fushi (especially in Parona's form), Fushi is understandably revolted and confused at these actions. When they have to explain to Kahaku how much they disliked him forcing himself onto them, he immediately tries to apologize and keeps his distance when asked. When he's comforting Fushi in the middle of the war, he tries to console him the best he can until his Nokker starts to "kill" all of Fushi's forms and he attempts to cut his arm off to stop it. When the others find him afterwards, he's clearly in shock and profusely apologizing to Fushi.
Single-Target Sexuality: After his feelings for the immortal grew, Kahaku stated that he would like Fushi no matter his gender. He's not homosexual, he's Fushi-sexual.
The Lost Lenore: A downplayed version. Of all Fushi's companions in the battle at Renril, Kahaku was the only one he failed to bring with him into the current era. Although Fushi said it was better that way, Tonari points out that Fushi wants to be close to Mizuha to make up for it.
The One Guy: From such a long line of female successors, he's the first male from it.
Tragic Hero: Since his birth he was considered unfit to carry Hayase's legacy but he was chosen anyway when his mother die in childbirth. Still, Kahaku decided that he would do his best to be useful to Fushi but a combination of his twisted bloodline and the Nokker on his left arm would prevent him from fulfilling that wish, making him the closest person to "kill" Fushi, even thought against his will. In the end, it was only through his Heroic Sacrifice Kahaku managed to kill the Nokker on his arm and restore all the vessels that it stole from Fushi.
Undying Loyalty: To Fushi. So much so that he not only attempts to cut off his left arm to free himself of the Nokker in it who tried to "kill" Fushi, but he also ends up sacrificing his life to wipe out the church and the Nokker in his arm as well. Even his dying breath is used to declare he loved Fushi as he falls into the molten metal below.

Mizuha

The eighteenth successor to Hayase's legacy. and one of main characters of Modern Era.

Abusive Parents: Her mother is a combination of Control Freak, Education Mama who sees her as a Trophy Child, being very demanding and always pushing Mizuha to be the best at something while forgetting about her successes. As a result, Mizuha has close to no free time at all, and that pressure and lack of freedom has made her believe that her mother only saw her as a trophy to brag about. She doesn't realize that her mother does really love her and was only trying to protect her from the Guardians.
Academic Athlete: Mizuha is one of the top students in the school and very skilled at sports, music and dance.
The Ace: Mizuha is outstanding in everything she does, besides being beautiful and popular. However, that made her the target of envy for several girls at school and she had trouble empathizing with others. See Broken Ace below.
Ambiguously Bi: Mizuha is clearly interested in Fushi and tries to make him fall in love with her, but it is implied that she is also attracted to her friend Hanna, even impulsively kissing her after being rejected by Fushi.
Bitch in Sheep's Clothing: Downplayed, but still present. Mizuha superficially looks like a kind and reserved girl, who doesn't socialize with others because she doesn't have time due to her mother being too strict. Although this is true, Mizuha also does not socialize with others because she is arrogant and a perfectionist, seeing no value in hanging around with people whom she considers inferior to her, which borders on practically everyone. Despite this bad personality, Mizuha sincerely appreciates the company of Hanna and the rest of the Occult Club, even though, by her own logic, they would be below her.
Broken Ace: Despite being The Ace in studies and sports, in reality, Mizuha has been raised to see herself as perfect and everyone else as imperfect. She doesn't understand why the people around her have trouble with the things she finds to be easy and looks down on them. Her desire to be perfect is strong enough to make her want to end her life before she becomes an adult, thus preventing her body from becoming imperfect with age.
Clingy Jealous Girl: According to the Nokker in her body, the reason why it attacked Funa is because it felt jealously from Mizuha's emotions after she saw Fushi and Funa together. So her Nokker possessed her to appease her feelings. This implies that Mizuha does feel jealous if any girl gets too close to Fushi, the one she really likes.
Desperately Looking for a Purpose in Life: Mizuha had many "hobbies" in her life, from playing the piano to dancing ballet and being in the naginata club, but as soon as she wins an important tournament she promptly leaves the club because she feels satisfied and then bored, not attaching herself to any of clubs. This habit is not helped by the fact that her mother immediately presses her to join another club instead of allowing Mizuha to find herself. However, her meeting with Fushi changed that, making she determined to "obtain" him and become "truly perfect". This sudden, newfound goal ostensibly provides Mizuha a more positive outlook on her life, causing her to become more accepting with her "imperfect" family and friends.
Dude Magnet: She is quite popular, receiving several confessions from boys at her school but rejecting everyone who confessed to her. This had the downside of getting her to be ostracized by the other girls at school who, out of jealousy, spread malicious rumors about her.
It's All About Me: A big flaw of hers. Mizuha seeks so much to be perfect that she also wants those around her to be perfect for her too. This led to her having trouble socializing, as it was virtually impossible for her to accept someone who wasn't up to her standards and part of her interest in Fushi is because she believed he would make her perfect. This is downplayed because she enjoys the company of Hanna and other "imperfect" friends and despite her motivation to fall in love with Fushi her love for him is genuine.
Love Bubbles: It appears quite often when she interacts with Fushi due to his power to feel the feelings of people around him, indicating that Mizuha's love for Fushi is genuine.
Matricide: Because of the Nokker inside of her wanting her to feel peaceful, Mizuha murdered her own mother, with herself having no memories or even understanding why she did it.
Modesty Shorts: She wears her gym shorts underneath her school uniform.
Mood Whiplash: A rather disturbing case where she sometimes acts unfazed after what happened to her mother and acts as if everything is still fine even though it's not. This does scare Fushi quite a bit when helping her out. This foreshadowed that the Nokker inside of her is slowly affecting her mindset.
Narcissist: Mizuha has a strong need to be seen as perfect and at the same time she sees no reason to associate with people she feels are below her. This is downplayed because Mizuha is aware that her personality is awful, and despite what she think about associating with people "below" her, she genuinely appreciates the Occult Club members' friendship, especially her friend Hanna.
Please, Don't Leave Me: Mizuha freaks out when Fushi suggests reviving her mom. She can't bring up a logical reason as to why Fushi shouldn't bring her mom back, but still she begs him not to. This implies that she realizes that, if her life goes back to normal, she can't be close to Fushi.
Sins of Our Fathers: Downplayed. Although Fushi and his friends do not hold her accountable for the actions of Hayase's lineage, Tonari still remains suspicious and makes it clear that she does not like Mizuha, warning Fushi not to be close to her, because as far as Tonari is concerned, Mizuha is no different from their ancestors, innocent or otherwise.
Stepford Smiler: She constantly smiles to maintain the image that she is a perfect girl for others and for herself, but in reality she is a lonely, depressed and suicidal girl.
Trophy Child: Mizuha feels that her mother, Izumi, tries to satisfy her sense of worth through her achievements, even if she deprives of her own life in the process. This would culminate in the Nokker that inhabits Mizuha's body taking control and murdering Izumi, replacing her with another Nokker that, ironically, would be the perfect mother that Mizuha has always wanted.
Used to Be a Sweet Kid: Mizuha was really just an innocent child in the past who loved her mother very much. But the pressure of her mother avoiding the Hayase family cult and the Nokker hibernating in her body greatly changed her personality in the present.
Violently Protective Girlfriend: Although she is not really Fushi's girlfriend, she is quite protective of the immortal and does not tolerate violence against him. Considering what happened to the boy who punched Fushi, the fact that a mere slap of hers caused the poor boy Body Horror similar to Parasyte, it is scary what she can do if she is really angry.
"Well Done, Son" Guy: Years ago, seeing her mother depressed and wishing to die (not knowing that Izumi had just found out that Mizuha's father was a member of the cult she sought to escape), Mizuha asked how to make her want to live and Izumi made her daughter promise that she would be The Ace in everything she did. Although Mizuha managed to keep her promise and become an outstading girl, over time she came to resent her mother for being deprived of friends and social life. The Nokker inside Mizuha, judging that Izumi was a source of suffering for her daugther, decides to kill her and replace her with a Nokker to eliminate the source of stress from her life.

Enemies

Nokkers

General

https://static.tvtropes.org/pmwiki/pub/images/nokker.png

Nokkers are unknown creatures that were created to impede Fushi's progress in preserving the world.

Arch-Enemy: The Nokkers consider the Beholder theirs, and by extension, Fushi is also one for being his successor. Partially subverted in the Modern Era, as although the Nokkers still want revenge on the Beholder, they are willing to try to coexist with Fushi.
Anti-Villain: Although they appear at first glance to be creatures that spread death and destruction wherever they go to try to kill Fushi, the Nokkers have altruistic goals: In the universe of To Your Eternity all who die go to Nostalgia Heaven, where they can be at peace and safe from experiencing any kind of pain, and from their perspective the Beholder, and therefore Fushi as his successor, are forcing people to experience needless suffering, which is why they "save" as many people as possible.
Blue-and-Orange Morality: From their perspective, the Beholder has trapped people's souls within bodies, and they are determined to save and take them to the other side, where they will be free of their heavy, painful and suffering bodies. Thus, Nokkers kill people so that they can go to Paradise, not understanding why humans would prefer to live.
Determinator: Regardless of whether you agree with the Nokkers' goals or not, it must be admitted that they are quite persistent, not caring how many times they are defeated or how many centuries the conflict with the Beholder and Fushi lasts, Nokkers will keep trying to "save" people.
Meaningful Name: The Beholder named them "Nokkers" because they "Knock on the doors of paradise, seeking its destruction."
Mercy Kill: Justified and subverted. In the world of To Your Eternity all those who die will go to Paradise, where they experienced a Nostalgia Heaven in which all their dreams are fulfilled and they cannot experience any pain. Therefore, from the Nokkers' perspective, all the deaths they caused were justified because their victims went to Paradise. What subverts this trope is that the Nokkers will "save" people whether they want to or not, not understanding why people would want to go on living.
Not Quite the Right Thing: This is part of the reason it has become quite difficult for Fushi to face them in the Modern Era. As Beholder points out, although the Nokkers are controlling the bodies of corpses and also the bodies of living people, taking over people’s lives in the process, this is not necessarily a bad thing. The case of Michi, Sumika's sister, is an example: Michi was suffering from a serious illness, and she wanted to die and be put out her misery. When she died, a Nokker took over her body and pretended to be her and Sumika glady accepted this as a miracle. Because Michi's soul went to Paradise and not intending to take away their happiness, the Beholder decides to allow the Nokker to continue pretending to be Michi. He explains to Fushi that some people don't want to live and that not every Nokker should be killed depending on the circumstances.
Resurrective Immortality: Unlike Fushi, Nokkers don't regenerate after being killed. However, as they were souls who resided in paradise in the first place, once they are destroyed on the physical plane they return to paradise until they can reincarnate again. Thus, because Nokkers are spiritual lifeforms they cannot be permanently killed.
The Symbiote: How they currently adapted to live in the Modern Era. This process is divided into three categories:
- Carrier: Nokker is inside the person, but hibernating;
- Half-merged: Nokker has awakened. Take control of consciousness and body sometimes. The host cannot remember what happened during the period when the Nokker used the body;
- Fully-merged: The host's soul is gone, leaving only the Nokker inside the body, which has completely taken over, living the life of its host.
Taught by Experience: What makes Nokkers dangerous is that they learn from their losses and adapt their tactics to have a better chance of winning against Fushi. For example, when Gugu managed to kill a Nokker using his Booze Flamethrower, the next attack was a rock-covered Nokker to protect himself from fire. Another example was when Fushi spread his roots for all Renril to kill all Nokkers in the area, they started using catapults to attack from a safe distance and out of Fushi's reach.
- In the "Modern Era". As Fushi proved too strong for the Nokkers to be able to defeat him, the Nokkers adapted to decrease their size at a microscopic level, making it impossible for Fushi and the Beholder feel their presence. As if that were not enough, they adapted to become symbiotes with humans, and now they can have temporary control of the host or even take over the body in the event of death of the host.
Well-Intentioned Extremist: The primary objective of the Nokkers is to rescue people's souls and take them to Paradise, where all dreams and desires are realized and no one can suffer any pain. And when they refer to rescuing souls, they refer to getting them out of their bodies, even if it means killing them, not understanding why people chose to live instead of going to Paradise.

Hayase's Nokker

The Nokker that has been with Hayase since she left Jananda. This Nokker first appeared trying to take control of Hayase's body, but she managed to get rid of the creature and then followed her on the boat Fushi left her on the middle of the ocean. Somehow, this Nokker attached itself to Hayase's arm and has been passed down her bloodline ever since.

Category Traitor: This Nokker is considered this by its peers for living in symbiosis with the Hayase clan instead of saving them (read:kill them). However, in the Modern Era this Nokker seems to have become a respected figure among its kind.
Even Evil Has Loved Ones: As erratic and strange as its relationship with the Hayase clan is, there is evidence that this Nokker developed affection for Hayase's descendants:
- When it stole all of Fushi's vessels and started using Eko's body to escape, Kahaku, who was chasing it to return the vessels to Fushi, said the creature was quite cold to abandon him after all the years they were together. After a brief fight, for a moment the Nokker uses a tentacle to caress Kahaku's face, then returns back to his body, even though there is no longer any need for the Nokker to maintain this symbiosis, indicating affection for his host.
- When the Nokker reveals itself to Fushi in Modern Age, it declares that it reincarnated specifically to help Mizuha after picking up her SOS, and that the murders it carried out using Mizuha's body, such as killing her mother, who was too rigid and was chiseling away Mizuha at her own life, replacing her with a Nokker that would allow her to live more freely, and Funa, whom Mizuha feared was a possible romantic rival for Fushi's feelings, were aimed at helping her and reducing the stress in her life.
Humanity Is Infectious: It is strongly implied that because of the symbiotic relationship it had with Hayase's descendants for centuries, this Nokker came to understand why humans want to live, to the point that when Pocoa asked why it didn't leave Kahaku and go back where it came from, the creature expressed to be afraid of dying and losing everything it's acquired, which would be a betrayal of the Nokkers' logic.
Villain Has a Point: Once it becomes communicative in the Modern Era, this Nokker raises points and makes accurate assessments that are hard to deny.
- After it reveals itself to Fushi, the Nokker defends the deaths of Izumi and Funa on the grounds that it was necessary to make Mizuha's life better. Although Funa's death was Murder the Hypotenuse and is hardly justified, the argument that Izumi was an Abusive Parents for Mizuha is correct and Izumi herself admits that she was a toxic parent to her daughter.
- When Fushi is asked if he would cry if Mizuha died and says yes, the Nokker immediately calls him a liar and points out he never cried, already arranged a rope to escape anytime he wants to and nothing he says rings true. Fushi implicitly admits that Nokker is right and decides to remove the rope to show good faith.

Izumi's Nokker

The Nokker who took control of Izumi's body after Mizuha was controlled to kill her mother.

Alas, Poor Villain: After her husband commits suicide, she falls into a pit and from there sees Mizuha fall and die beside her, the Nokker loses the will to live, decides not to heal her injuries and die there. Fushi, sympathizing with the creature, leaves a hair tie in her hand and says the next time it's reborn they'll be friends.
Becoming the Mask: This Nokker's mission is to replace Izumi and be a good mother to Mizuha in her place. Over time, it eventually came to feel genuine affection for the family, as she asked Mizuha to go home so she wouldn't witness her being killed by Fushi and also despaired when her husband committed suicide, admitting that she loved him.
Good Parents: For Mizuha, which contrasts with the real Izumi who was an Abusive Parents to her daugther, albeit with a Freudian Excuse. The Nokker who pretends to be her mother is kind, doesn't pressure Mizuha and allows her to socialize with her friends, and because of this Mizuha ends up begging Fushi to spare this Nokker even if it means not having her real mother back.

Mimori's Nokker

The Nokker who took control of Mimori's body after her suicide. It is the first Nokker-infested person Fushi faces.

Ax-Crazy: A psychotic, murderous sadist Nokker, it enjoys fighting Fushi, not hesitating to try kill people in the battle and torturing others for fun.
Face of an Angel, Mind of a Demon: At first glance may look sweet and nice, but this Nokker is quite malicious and violent. This is subverted because Mimori, the true owner of the body, is a genuinely sweet and nice child
Kill It with Fire: How it met its end. After Funa's Nokker decapitates it, it starts to regenerate from the head, but is then left inside a bucket of firecrackers, dying incinerated and showing the way to kill Nokkers in the Modern Era.
The Millstone: The reason why it is destroyed. The Nokkers' current goal in the Modern Era is to coexist with Fushi and since Mimori's Nokker proved to be too bloodthirsty and out of control, to the point of nearly killing Hirotoshi, Funa's Nokker was forced to destroy it to prevent the chances of coexistence between the Nokkers and Fushi become even smaller.
Troubling Unchildlike Behavior: After Hirotoshi confronts if it's the real Mimori, the Nokker drops the pretense of being her, asks if he's going to kill her, shows her panties and says it's his dear sister. If that wasn't enough, the Nokker would start torturing Hirotoshi with BDSM practices since then.
Villain Has a Point: While definitely sadistic and bloodthirsty, some of the points it raises turn out to be valid:
- When Fushi accuses that the Nokkers are stealing people's bodies, the Nokker points out that the most accurate would be to say that they are "dwelling inside living humans", and it also bring up that Mimori couldn't stand her mother's neglect and abuse anymore, which is why she was Driven to Suicide and the Nokkers were not responsible for her death. Mimori herself later came to admit that it was she who chose to take her own life, and if not for the Nokker taking her body, she would have died that day.
- After Fushi demands that the Nokker return the body to Mimori, the Nokker say that it was Mimori herself who took her own life. If Mimori doesn't want to live, by what right can Fushi force her to come back to life?
- When Hirotoshi says he's going to help Mimori live peacefully and happily, the Nokker laughs and points out that Hirotoshi doesn't have a job, spends his time jerkin' it to little sister stuff and isn't able to make friends for her. Although Hirotoshi decides to force the Nokker out of her body, he is unable to counterargument these facts.

Funa's Nokker

The Nokker who took control of Mimori's body after being murdered by the Nokker who dwells in Mizuha.

Anti-Villain: Funa's Nokker itself only wants coexistence with Fushi and humanity, explaining that she destroyed the Mimori Nokker because it went out of control. However, it doesn't justify the Nokker removing Funa's spirit from her body or attack the Beholder.
Forced Transformation: After the failed attempt to assasinate The Beholder, he subjugates the Nokker to this by morphing Funa's body into a flower. This allowed him to easily extract the real Nokker before burning the Nokker up in his hands. Thankfully, Fushi recreates her body to resurrect the real Funa.
Major Injury Underreaction: Besides struggling to breathe from a naginata wound, she immediately gets back up in a pool of her own blood and acts as if nothing happened. It's later revealed that this is a Nokker Funa and Nokkers are known to have regeneration powers after all.
Mood Whiplash: After getting impaled by Mizhua's naginata, she suddenly stands back up and congratulates Fushi and Mizuha as if they just became a couple. This freaks out Fushi very much as the entire scene is already very disturbing as it is.
Oh, Crap!: The Funa Nokker gets caught off guard when she realizes that The Beholder still has some of his powers in his human body.
Villain Has a Point: Regardless of the morality about this Nokker taking control of Funa's body, it is absolutely right to call out Funa's friends by saying they were going too far with bullying Mizuha right after they purposely hurt her.
Villainous Rescue: She first appears with Hayase's naginata in her hand and helps defeat the Mimori Nokker with firecrackers. This leads to Fushi pursuing his investigation involving her and why she helped him and his friends.
Would Hurt a Child: Despite her claims of coexistence, the Funa Nokker isn't above using human hostages to save her own skin. This included using one of Sumika's kids as a human shield. Then she even tried to assasinate The Beholder, who's in the form of a young boy.
- Downplayed. In the case of Sumika's sister, she was a Nokker and so wasn't really in danger but only was used to delay Fushi. As for the Beholder, despite his childlike appearance he remains a old entity with god-like powers so it is difficult to consider him a child.

Others

Church of Bennett

The Church of Bennett (ベネット教) is the name of a group that follows an unnamed religion. They see Fushi and his followers as heretics, believing Fushi to be a being that attracts danger rather than someone who fights to protect them.

Burn the Witch!: When the Church succeed in capturing Fushi, they trap Fushi inside an iron cube and pour molten iron inside, hoping it would be enough to kill him or at least seal him. However, after weeks in prison, Fushi's Healing Factor adapted and he gained the ability to emit heat from his hands strong enough to melt the iron that imprisoned him and escape.
Dropped a Bridge on Him: After being Put on a Bus for the rest of Season 2, the season finale reveals that they, along with Cyrila, were blown up by Kahaku in a Suicide Attack.
Hate Sink: In contrast to Hayase's clan, which despite its members' tendency to be Stalker with a Crush about Fushi, proved to have redeeming qualities with characters like Kahaku and Mizuha becoming close enough to be considered friends by the immortal, and the Nokkers, who have selfless goals despite the death and destruction they cause, the Church of Bennett doesn't have the slightest sympathetic qualities and only seems to exist to be hated.
Historical Hero Upgrade: According to the records of the Bennett Church, High Cleric Cylira defeated Fushi and is therefore the savior of the whole world, but was treacherously killed by Kahaku, one of Fushi's associates. The problem with this version is that it conveniently omits that Fushi stayed alive and saved Renril's city, Cyrila was a Tautological Templar Jerkass, and that he was the one who tried to kill Kahaku in a treacherous way, only for it to backfire and for him to end up being killed by Kahaku's Heroic Sacrifice.
Kangaroo Court: Their trials are quite similar to those from the Witchcraft Trials. When Bon is tried for helping the demon Fushi, he is taken to a suspended cell, poorly fed and the whole trial was to wait for Bon to no longer endure the horrible conditions he was kept in and confesses his "sins".
Karma Houdini Warranty: After their arc ended with them seemingly killing Bon and then getting away unscathed, the Season 2 finale later reveals that they were ultimately killed, along with Cylira, when Kahaku blows himself up in his Suicide Attack.
Tautological Templar: In particular the High Cleric Cylira, but the Church of Bennett in general has that stance. Fushi give money and food to people in need? This is the work of a demon and they must be punished for accepting his help. Prisoners subjected to a sham trial and without food are about to die? If they are innocent God will save them in some way. If not, they deserved to die anyway.
