Characters / The Executioner and Her Way of Life

Character list for The Executioner and Her Way of Life. Page is under construction and beware unmarked spoilers. All major spoilers from Volume 5 will be marked.

The Main Quartet:

Menou

Voiced by: Iori Saeki (Japanese), Annie Wild (English)

The protagonist of the story. She has the undesirable duty to eliminate any and all Lost Ones that enter her world or they may face more calamities.

---

• Action Girl: A trained executioner who is among the best in the business. Her first fight scene has her taking several armed combatants by herself.
• Ambiguous Situation: The factor that changed Menou's Guiding Force in her Dark and Troubled Past is referred to as having been "bleached". This same phrasing is used for how "Ivory" is able to overcome even other Major Human Error's powers, their pure power of white overwhelming them through "bleaching" what it comes into contact with. Orwell also notes the abnormality in their fight, which makes sense when you learn that she is a creation of Ivory.
• Apologetic Attacker: She feels regrets over all the innocent lives she has taken. While it is her duty to kill Lost Ones, she also knows that they were innocent people who had no idea why she had to kill them in the first place.
• Becoming the Mask: Part of the plot line revolves around Menou changing. As early as the train hijacking, she starts showing genuine care for Akari, and she is stunned by how much Akari trusts her.
• Born Unlucky: Lost her home village to a Lost One, ends up accepting the duty to kill more Lost Ones, and gets her life thrown through the wringer in her pursuit and work around them as what little of the world that knows about her spurns and fears her existence, either for being an Executioner or for being Flare's student. This isn't even considering the fact that it isn't the first time Akari's run a loop of their journey together, because Menou seems to die one way or another at almost every turn since they attract all sorts of trouble and end up going against her mentors and faction inevitably.
• Borrowed Catchphrase: She likes to present herself as a "Priestess, pure, proper and powerful". A flashback shows that she got that from her mentor.
• Chick Magnet: She appears to have no issue with gaining the affections of Akari and Momo. Sahara comments that the rumours surrounding Menou claim that she seduces girls wherever she goes, but given Sahara's personality, she could be making this up to mess with Menou. Sahara herself could also count, as she has complicated feelings for Menou that mix admiration and envy. It's even stated in Volume 5 that Menou is Sahara's ideal beauty.
• Combat Pragmatist: Being an assassin, Menou's fighting style is geared towards dealing with enemies fast, using agility and misdirection to hit vital spots.
• Dark and Troubled Past: The Sole Survivor of a Lost One incident when she was a child that wiped out her home. It also didn't help that Flare and Orwell promptly murdered the Lost One directly in front of her while she was profusely apologizing for the destruction she wrought. Later volumes imply that Menou never existed in her hometown, however, leaving it ambiguous as to how or why she was there to be found by Faust.
• Deadpan Snarker: A surprisingly important aspect of her personality. Menou fakes being a Nice Girl when going undercover, but in reality she has a sharp wit and is unafraid to criticize others. Thus, the more she gets snarky with Akari, the more she is letting herself get closer to the girl by showing Akari her true personality. This greatly concerns Momo.
• The Dreaded: She isn't as feared as her master Flare yet, but reactions from numerous mooks through the series show that the name Flarette is also becoming infamous in the world.
• Enemy Mine: By the end of volume 6, Menou is hopelessly outmatched against the Faust as a whole now that she has been branded a criminal with none of the resources she had as an Executioner, and the time resets that keep saving her are completely absent since Akari's is paralyzed as a Human Error. So she gets together a team consisting of herself, her not-quite-friend Sahara, and avatars of two of the Major Human Errors - Pandaemonium and Vessel - in a downright heretical recruitment, as she needs every ounce of aid she can get, and Pandaemonium's goals align with Menou's.
• Everyone Has Standards: A major trait of Menou is that despite her claims to the contrary, she really does have a moral code. This manifests fairly on when, after killing Mitsuki, she kills the members of the Fourth who were involved in summoning him. In her eyes, while what she did was necessary if cruel, the members of the Fourth called upon an innocent person just to use him as bait, knowing that he would almost certainly die—she considers them about as responsible for his death as herself.
• Foreshadowing: She has repeated dreams of the Lost Ones she's killed, and seems to think that this is a PTSD nightmare of trauma for what she's done, though the anime opening also goes to show Menou and Akari there too. She's actually dreaming through Ivory's eyes, as Ivory contains the memories of everyone in this world, including Lost Ones; the school uniform Menou is Ivory herself, with Menou being made in her image.
• The Heart: Ironically for someone that is supposed to be a remorseless assassin, Menou is effectively the binding tether for Akari and Momo, and her underlying kindness helps drive her journey even if it amounts to trying to Mercy Kill Akari. Her entire creed of being an Executioner is built upon the idea of doing it so others like Flare or Momo don't have to, meaning she effectively is willing to sacrifice herself for everyone else's sake without thinking twice.
• Hero-Worshipper: She considers Master Flare to be the epitome of everything she wants to be. Momo states in Volume 5 that Flare is a more important existance to Menou than even Akari, which is saying a lot.
• Hitman with a Heart: While she wants it to be true it is established early on that Menou is not a heartless killer. She feels regret over the sins of her past killings, to the point of constantly dreaming of her past victims.
• In Love with the Mark: The premise of the story involves Menou developing feelings for Akari over the course of their journey.
• Locked Out of the Loop: There's larger info and story implications that even she isn't privy to. This happens primarily because Akari's found out the hard way that if she ever reveals too much, Menou's faith could be shaken and cause her to leave her path of the Executioner, which means Flare will inevitably show up and murder Menou for it. Unlike most examples, however, Menou gets enough hints to gradually piece together the mystery, keeping her never too far from the truth on her own terms.
• Loss of Identity: In a different manner than the Lost Ones. Her Dark and Troubled Past resulted in a death of self, in a metaphorical and mental sense, so Menou was effectively "reborn" the day she lost everything, and it took years to reform into what she is in the present. Though, as revealed in the epilogue of volume 5, she was a blank slate to begin with.
• Mary-Sue Hunter: A rare non-fanfiction example: an assassin sworn to target extrauniversal intruders from "our" world who seek to turn hers into their personal Power Fantasy.
• Meaningful Name: Her name, as explained by Ivory, her creator, is a combination of the Japanese words me (eye) and nou (brain), describing her role in relation to Ivory.
• Morality Chain: To Momo. As she's the only one Momo gives a shit about, and the only one that can control her, if she were to die, based on the fact Momo once killed a dragon with her bare hands, the damage would be catastrophic.
• Necessarily Evil: Menou sees herself as this to protect her world against potential calamities. She doesn't like killing the Lost One, and she knows what she did to her previous victims was wrong, but she does it because she believes she has to.
• Protagonist Title: She is the titled Executioner.
• Red Baron: As she is the best disciple of the infamous Flare, she became known as "Flarette".
• Screw This, I'm Outta Here: One way or another, Menou seems to consistently leave Faust and become a former Executioner due to being so dedicated to both caring for and ultimately killing Akari that her goals clash with her employer's. Flare consistently kills her for this, making these paths a dead end and another reset for Akari — until the latest timeline, where a number of both manipulated and chance variables start coming together to keep her alive far longer than normal, some rewinds being necessary aside.
• Sexy Slit Dress: Menou wears a modified version of the priestess robes with a very high slit at the thigh, which allows her access to the dagger she wears on a garter. It also means every volume of the light novels will have at least one scene that mentions how shapely her legs are.
• Spanner in the Works: By using a shard of the Sword of Salt to stop Akari's transformation into a Human Error, she ruined Flare's plan to use that same shard to kill Ivory.
• Spell My Name With An S: While her name could be translated into either Menou or Mehou, the official spelling is Menou.
• The Unchosen One: Generally speaking, Menou is fated to die, whether in her line of work or to Flare if she leaves the path of the Executioner, among other causes. But because of Akari's Save Scumming machinations turning back the timeline over and over in an attempt to seek a path where Menou lives, this has ended up making Menou into the "protagonist" of the story without even realizing it, while disrupting fate significantly in the process — and causing the seals on the remaining Major Human Errors to gradually break, which means Menou ends up having to be the person that confronts them.
• Unique Protagonist Asset: Every person has one Guiding Force as their primary power, though external tools such as Menou's bible can be used for extra abilities. Menou, however, lost her own inherent Guiding Force because of her Dark and Troubled Past. The event "bleached" her soul from the sheer trauma, which makes her capable of linking into other Guiding Forces with abnormal ease, and can purify and amplify other's powers in the right circumstances.
• Weak, but Skilled: While no one will say Menou isn't a good fighter by herself, compared to the rest of the named cast, she looks to be a little lacking in firepower and special abilities. Flare even pointed out that her physical and magical abilities were subpar when Menou started her training. She makes up for this by carefully exploiting every opening available, using her weapons creatively, and playing dirty. Realistically, however, this can only do so much against some of the threats she deals with, and against someone like Flare, who taught her everything she knows, Menou is on a fast track to another reset from Akari.
• Well-Intentioned Extremist: Kills teenagers who have done nothing wrong before they can potentially cause massive amounts of damage. Since Pure Concepts corrupt and override the soul, it's not even a matter of not trusting them. Even Mitsuki, her latest victim at the beginning of the story, showed signs of corruption almost immediately after he discovered what he could do.
• You Monster!: Menou is seen as this by the knights she faces at the start of the story. She retorts that the Lost Ones they helped summon are even bigger monsters.

Akari Tokitou

Voiced by: Moe Kahara (Japanese), Melissa Molano (English)

A young Japanese girl who was summoned into Menou's world against her will. After arriving in this world, she unlocked the ability to reverse time making it nearly impossible for anyone to kill her. She decides to go on a journey with Menou because she believes meeting Menou was fate.

---

• Action Survivor: Akari is this due to her magical ability.
• Ambiguously Gay: Menou makes note that Akari forms an attachment to her rather quickly after their first meeting. Akari believes that meeting Menou was fate. She keeps it ambiguous intentionally, as her true personality is unambiguously in love with Menou, but has to manipulate the outcome in specific ways to avoid Menou getting killed yet again.
• Brainless Beauty: She's both the most conventionally attractive and frequently-fanserviced member of the main cast, and the dumbest.
• The Chessmaster: Turns out her ditzy appearance is not necessarily all she is, and she is capable of making very complicated plots in order to save Menou. Take a look at her gambit in taking down Orwell as an example.
• Clingy Jealous Girl: The true Akari borders on Yandere with her obsession for Menou. When Menou's fighting Orwell and are way out of their league, for example, Akari intentionally destroys some hair ribbons Menou had given Momo years ago, both to incite Momo into a Rage Breaking Point so that Menou can get some backup in time... and because they were a handmade gift Akari herself hadn't received from Menou, just to be petty.
• Death Seeker: She seeks to travel with Menou to the salt sword, so Menou can kill her with it. This is because her experiences with time travel made her conclude the only way to ensure Menou lives is by getting killed by her.
• The Ditz: Most of the time, she's a complete airhead. A lot of jokes in the series come from the fact that Akari seems to view her time with Menou as nothing more than a big fun vacation, no matter how dangerous or serious things become. This does have a level of justification: her loops mean that her memory of her original life has decayed heavily, meaning she lacks a lot of knowledge and life experience.
• Genki Girl: Menou is baffled with how much energy she has despite being in a foreign world and getting thrown in dangerous situations everywhere.
• Hates Being Alone: Seems to be a major defining characteristic for Akari and a potential motivation for her willingly accompanying Menou despite only meeting her.
• Healing Factor: Akari's magical abilities allow her to survive any wound she receives even if it was fatal.
• Jumped at the Call: She immediately takes Akari on her invitation to come with her on a journey because she believes their encounter was due to fate. In truth, it's due to lingering memories of previous timelines. She did not jump at her call the first time.
• Laser-Guided Amnesia: Loses her memories of being affected by her own Time Master powers if they happen to be activated. In reality, she's actually sealing the usage of her rewinds away in her mind to counteract becoming a Lost One, as her true personality is bordering on being the concept of Time from the sheer amount of experiences she's had to go through and remember.
• Love at First Sight: She latches onto Menou immediately, trusting her completely and being very intimate with her. There's two reasons for this: the first is that the one thing her true personality allows her to maintain over the course of her loops is her feelings for Menou. Even though she's only known Menou briefly, she mentally regards her as if they've been lovers for months or years, and there. The other is that She bares the same face of a classmate who she may have had a crush on and who suddenly disappeared.
• Meaningful Name: The "Toki" in her surname means time.
• Ms. Fanservice: She has a larger bust than Menou, and if there is a fanservice moment in either of the adaptations, she will take part in it.
• Naïve Newcomer: Due to only arriving in this world, Akari is this by default. Until it's revealed she has actually been looping back in time for a while now. When her memories are released, she actually knows more than nearly the entire cast, by virtue of having literally seen the future.
• Nice Girl: She is shown to be very kind and caring even to strangers, as demonstrated when she helps a lost child at a station. Her hidden personality, however, is much less patient and gentle with people who are not Menou.
• Nice Job Breaking It, Hero: Turns out she is responsible for the return of the Four Major Human Errors. The spaces where they are sealed are completely cut off from the world, and thus unaffected by her time travels, but that means the barriers around them are pressed between a world that is rewinding in time and a world that refuses to move along with it, and the strain leads to "cracks" appearing.
• Nigh-Invulnerability: Her status as a Time Master means that there are few things in the world that can do her any permanent harm. The entire driving force of the series is whether anything can actually kill her; there are a few things that have been speculated to be able to do so, but even they're questionable.
• Ordinary High-School Student: She was this in Japan before being summoned into Menou's world.
• Satellite Love Interest: In spite of her situation, Akari doesn't seem to have many interests or objectives besides flirting with Menou. Justified because her memories of previous timelines are sealed and her memories of Earth have long been lost, leaving nothing in her mind except her love for Menou. Her true personality is much more complex, for good and for bad.
• Save Scumming: The true Akari has been rewinding the entire timeline backwards over, and over, and over because Menou ends up getting killed in some way or another, sometimes unavoidably. The best way to look at things is that Akari has effectively seen the various bad ends of a visual novel and keeps loading a save to try a different route. The current story is the latest attempt, starting from Akari's arrival to find an optimal route to prevent Menou from dying yet again, and as early as the train incident it becomes clear that she still has to intervene repeatedly.
• Time Master: Akari's Pure Concept allows her to rewind time to a few seconds just before she dies. However, she has no memory of her death when it happens nor is she aware of what her power is. This makes Akari virtually un-killable unless there is a way to remove it, which inspires Menou's journey with her. Her hidden personality can actively manipulate time, and cause things to decay in an instant, freeze people in place, and even time travel to earlier points in history.
• Unskilled, but Strong: Her true personality has no combat training or experience, but can manipulate time. Needless to say, she can take care of herself.
• Walking Spoiler: Though the anime hints at it far faster than the manga or light novel, everything involving the true Akari personality and her Save Scumming tactics to save Menou changes the entire tone and premise of the story.

Momo

Voiced by: Hisako Kanemoto (Japanese), Cat Thomas (English)

Menou's underclassman in being an Executioner. She decides it is best to keep tabs on Menou and Akari's journey just in case if anything were to go wrong.

---

• Action Girl: As an Executioner, she is this by default.
• Berserk Button: Under no circumstances should one even entertain the thought of messing with her hair ribbons. When Akari destroys them to get her good and riled up, she explodes. As in, she beats a giant dragon to death with basically her bare hands, and proceeds to level the nearby church.
• Clingy Jealous Girl: She is this to her senpai Menou to the point where she tries to kill Akari herself, so Menou won't be able to spend more time with her.
• Everybody Has Standards: Momo is a bratty, violent misanthrope who cares very little about anything unrelated to Menou, but even she is disgusted to discover that the source of monsterine is a little girl in an iron maiden, and even she feels compassion when she dies. She even tries to remove the girl's body, and its this unusual state of mind from her that allows her to be caught off-guard by a trap.
• Heroic Comedic Sociopath: Momo takes this role during the segments of Volume 4 that follow hers and Akari's point of view. She basically makes a hobby out of brutally beating up criminals, either for the sake of training Akari, or just to relieve some stress, then dismissing her actions as totally fine because her victims were crooks anyway.
• Hidden Depths:
  • In the light novel, Menou soon realizes, after Momo is introduced doing her Clingy Jealous Girl routine and none-too-subtly taking a candid photo of her, that she tends to act this way right after Menou went through something traumatic—meaning she's doing it to try to cheer Menou up.
  • While her concerns regarding Menou might partly be due to paranoia, she makes note that long term assignments are not Menou's specialty. Menou does not necessarily refute this point, but she makes it clear to Momo that she can handle her assignment to eliminate Akari.
• Lack of Empathy: Admits more than once to not caring about anyone that is not Menou.
• The Nicknamer: Loves to give unflattering nicknames to everyone she has to work with but doesn't like, which means everyone that she has to work with except Menou. For example, she nicknames the rather busty Akari "Boob lady" and Princess Ashuna "Princess Poo."
• Nominal Hero: Momo is a misanthrope who hates everyone and everything in the world except for Menou. Thus, Menou wanting to do good is the only reason Momo bothers doing good too.
• Rose-Haired Sweetie: Subverted, as she only acts like this when she is flirting with Menou. To anyone else, she can be rude, uncaring, and downright cruel, but definitely not sweet.
• Sugary Malice: Momo tends to be rude, if not outright antagonistic, to anyone who isn't Menou, but she tends not to drop her veil of politeness or cutesy way of speaking even when insulting people. This is best demonstrated when she calls Ashuna "little princess" in a way that makes it very clear that she's being condescending towards her (but Ashuna still likes it and insists on having Momo keep referring to her that way).
• Token Evil Teammate: Her loyalty to Menou ensures she is always on the side of the good guys, but she is a bonafide Nominal Hero who would rather see the entire world burn before seeing Menou get hurt.
• Undying Loyalty: Towards Menou. A flashback to the end of the first timeline shows that even after Menou abandoned her mission as an executioner to protect Akari, Momo still followed her and died trying to save her from Flare.
• Vibroweapon: Her main weapon is a coping saw. She can also make it vibrate with magic, allowing it to be handled like a blade.

Ashuna Grisarika

Voiced by: M.A.O (Japanese), Rachael Messer (English)

The youngest princess of the Grisarika Kingdom. She travels the world as a wandering knight, getting into fights with anyone who catches her interest.

---

• Adaptational Modesty: Her anime design◊ significantly fills out the clothes on her lower body to give her a proper skirt. Compare it to her design◊ in the light novels and manga, where her skirt is more of a belt with some cloth hanging off it worn around her upper thighs.
• Blood Knight: While she will help people along the way and help solve crimes, her lust for fighting is nonetheless a big factor in her constant travels through the continent: she is always seeking strong foes.
• Flaming Sword: Ashuna's signature weapon is a sword which she sets aflame with her magic.
• Friendly Enemy: Completely one-sided example with Momo. Ashuna adores her for providing a good fight when they first met, while Momo can't stand her presence.
• Good Is Not Nice: Within the main cast, she is the one with the most straightforward heroic motivation and objectives. However, she is still a Blood Knight eager to pick up fights as she travels and is ruthless as she fights.
• Hidden Depths: In a conversation with Menou in Volume 4, Ashuna admits she probably won't be able to run away from the responsibilities of royalty for much longer, and her current attitude is driven partially out of a desire to enjoy her freedom while it lasts.
• Hopeless Suitor: She seems to have a clear fondness for Momo that at least borders on romantic, spending a lot of their time together flirting with the other girl or making clear advances on her. Momo, however, has no space for loving anyone but Menou, and consequently rebuffs Ashuna at every turn.
• O.O.C. Is Serious Business: Ashuna is exceedingly easygoing, never taking insult to Momo's constant barrage of venom or seeming too perturbed by the danger that follows her everywhere. So, in Volume 4, when she suddenly appears in the middle of Momo and Menou's fight looking absolutely furious, both girls are taken extremely aback. It turns out she's so angry because she was poisoned and robbed by someone she extended her trust to: Menou... or so it seems.
• Proud Beauty: Ashuna explains to Momo that she thinks the inherent beauty of the human body shouldn't be hidden, and also declares that she finds strength to be beautiful. She proves herself to be exceedingly proud of her own strength, and her "flashy" taste of clothes happens to show off her chiseled abs along with her figure.
• Sarcasm-Blind: She is so happy to finally have a friend willing to give her a Affectionate Nickname, it doesn't even cross her mind that Momo calls her "Princess Poo" as an insult.
• Shameless Fanservice Girl: Claims that clothes exist to highlight the beauty of the body, which helps explain her own Stripperific choice of outfit.
• Stripperific: Her outfit is so scandalous, it's easier to list what she got covered above her hips: her neck, her belly button, some of her forearms, and her chest. That's it. And her skirt has a pretty big slit in it. The fact that it stays on can probably be credited to magic. Astoundingly, it isn't even the most risque outfit she wears in the series—that would probably be her idea of swimwear◊, featured in the third volume.
• White Sheep: Ashuna's parents are executed as criminals for summoning Lost Ones to the world, and Ashuna suspects her older sister was secretly involved as well. However, she herself has no involvement with her family's illegal dealings, instead fighting for justice as a knight.

Faust

Flare

Voiced by: Yuko Kaida (Japanese), Molly Searcy (English)

An (in)famous executioner and Menou's mentor.

---

• Bystander Syndrome: As a counterpoint to her Punch-Clock Villain status, it's pointed out that she only kills people after they committed a taboo, since that's the job of a executioner. If she ever meets a person that plans to commit a taboo, she won't lift a finger until they do it.
• The Dreaded: The most feared executioner in the setting, bar none. She is such an example of this trope, Menou manages to make Orwell lower her guard by casting a simple illusion of Flare over herself right in the middle of a battle, because Orwell is so scared of her showing up to ruin her plans her rational brain needs several seconds to catch up the obvious trick.
• Even Evil Has Standards: Beyond her Pragmatic Villainy below, she is very much not out to actually raise Priestesses to be Executioners if she can help it, offering them the opportunity to return to normal priesthood and homes by choice so that fewer girls had to stain their hands like herself. Menou stuck to her regardless since this filled in for her Loss of Identity, and Momo stuck with Menou like glue while most others left.
• Evil Mentor: By virtue of mentoring someone in the art of being Necessarily Evil. While she was serious about teaching Menou how to be an executioner, she won't hesitate to kill her own disciple if she strays from her path, and has in fact already done so in previous timelines.
• Invincible Villain: An interesting In-Universe example. Akari never even seems to consider defeating her, instead working towards making it so Menou doesn't have to fight her. Thus, she is talked about as if she was an unbeatable obstacle, one that spells certain doom when it shows up. Flare herself laughs at the way people act like she is invincible, but every fight scene she is in seems to confirm that it's not a good idea to try and fight her.
• Lack of Empathy: It's revealed in Volume 6 that Flare has genuinely never felt guilty about killing people, and not just because it's her job. She once decided to befriend her target to see if she would finally feel guilt about her murders, as she felt it was wrong to not have anything bad happen to her after killing so many people. She still didn't.
• Master of Disguise: She is highly proficient in using Guiding Camouflage to alter her appearance and she uses it to great effect in Volume 4 by impersonating Menou and Ashuna to fool both of them in order to abduct Akari.
• Necessarily Evil: She is the one who taught Menou this is what an executioner should aim to be. Her first lesson to her amounts to "accept you are the bad guy".
• Pragmatic Villainy: She kills her targets fast and has no mercy or kindness to give to anyone, but she won't kill someone who is not a target. That's simply not her job.
• Punch-Clock Villain: She has never killed anyone for any reason besides having been ordered to. It's one of the reasons she is considered a "perfect executioner".
• Retired Badass: Subverted. Menou and Momo think their mentor has retired from active duty and now merely trains new executioners at the monastery. In reality, she never did, because she had another job the girls didn't know about.
• World's Strongest Man: Short of the Major Human Error tier threats that can be One-Man Army calamities to the entire world, Flare is held as one of the deadliest native beings period, someone who will get the job done. It's why even just being Flare's student gets Menou a fair amount of bad reputation and fear alike. And as Akari's found out the hard way in previous loops, not even Menou is safe from Flare and has presumably never won against her, meaning any timeline with a Flare encounter is a dead end.

Archbishop Orwell

Voiced by: Tamie Kubota (Japanese), Shelley Calene-Black (English)

One of the Archbishops that lead the Faust, the Church of the setting and secretly the organization tasked with assassinating Lost Ones.

---

• Big Good: Introduced as the leader of the organization the main characters belong to. Subverted when it turns out she is a villain.
• Cool Old Lady: She is very kind and supportive towards Menou when they interact, going beyond merely being her boss and actively giving her life advice. Subverted, as it was only an act to manipulate her.
• Create Your Own Hero: Her attempts to summon Otherworlders illegally resulted in one getting loose and causing the Lost One incident that wiped out Menou's Doomed Hometown. Flare and even Orwell herself had shown up and took her in from the aftermath, having no idea that this would lead to Menou being the one to kill her years later once Akari gets targeted.
• Fallen Hero: She dedicated her life to saving as many people as possible. When she started feeling the years weighting her down, this turned into resentment that she used her life for the sake of others, not gaining anything for herself. The Director later implies she found out "the truth of the world" and lost her faith as a result. Namely, she found out about Ivory and how she has been dictating how their world works for a thousand years.
• Immortality Immorality: Orwell uses large numbers of people as human sacrifices in her pursuit of immortality.
• Immortality Seeker: Orwell seeks to use Akari's Pure Concept of Time to gain eternal youth.
• Intergenerational Friendship: Some conversations between Flare and The Director in Volume 4 imply Orwell was a close friend of them years ago, despite the age gap.
• Karmic Death: She plotted to use Akari's Pure Concept to regain her youth. Instead, Menou taps into it to kill her by Rapid Aging.
• Never Mess with Granny: Her old age does nothing to make her less of a threat than the young executioners.
• Small Role, Big Impact: Only shows up in the first volume, but it later turns out she was crucial for the plot of the entire series turning out the way it did. Because she is the Starter Villain and someone Menou trusts, any attempt by Akari to tell Menou the truth about the time travels or running away only leads to Menou dying by Orwell's hand. Thus, Akari has to find a way for Menou to survive without her finding out the truth through trial-and-error and lots of time travel, leading to the current timeline.
• Starter Villain: The main antagonist of the first volume of the series.

Sahara

An old "classmate" of Menou and Momo back from their days training at the monastery.

---

• Arm Cannon: Picked one up as a result of her adventures in the Mechanical Society.
• Early-Bird Cameo: She is mentioned in Vol. 1 when Momo is reminiscing about her time at the monastery as an unnamed child who tried to steal Momo's ribbons and gets beaten up by Momo who then steals her clothes to make Menou's scarf ribbon. The child is revealed to be Sahara in Vol. 3.
• The Gadfly: She really gets a kick out of playfully flirting with Menou and teasing her about her supposed status as a "ladykiller."
• Heel–Face Revolving Door: Zigzags between helping Menou and supporting the villains of the setting, due to some heavy internal conflict regarding her relationship with her.
• I Just Want to Be Special: The crux of her character arc is that she wants to feel special and be recognized by others as someone special.
• Nun Too Holy: Most of the members of the Faust we meet aren't exactly matching the ideal, but Sahara barely even tries to give the impression of being a holy woman.
• Shipper on Deck: Claims to be a Menou x Akari shipper, though this has less to do with her liking the ship and more to do with her really hating Momo.
• Tareme Eyes: It's mentioned that she has droopy eyes that make her look sleepy, which fit her mellow demeanor but greatly contrast the provocative things she sometimes says.

The Four Major Human Errors

Pandaemonium

Voiced by: Anzu Haruno (Jaoanese), Juliet Simmons (English)

A Japanese girl who was summoned by the Ancient Civilization a thousand years ago and contributed to its collapse before being imprisoned within a barrier of fog. Her Pure Concept, "Evil", forms the root of all "Original Sin"-type Guiding Force invocations and is the source of all of the monsters and demons that can be found in the world.

---

• Even Evil Has Standards: She implies that she holds nothing personal for Ivory despite being sealed away by them, as whatever happened with their Pure Concepts had forced Ivory to fight them, and even openly pities the circumstances that made former fellow Otherworlders fight eachother.
• Exact Words: During their brief meeting in Volume 2, she tells Akari that there is a way to go back to Japan. Two volumes later, Akari discovers the ritual to do so requires the sacrifice of a third of the population of this world, and the destruction of an entire continent for "materials". She is not happy to hear this and accuses Pandaemonium of lying to her. The girl replies that all she said was that a method exists.
• For the Evulz: As one of the elder Lost Ones, her personality has long been overwritten by her Pure Concept, which in her case just happens to be "Evil". So now doing evil is all that is in her mind, and she couldn't be having more fun doing it.
• Generic Doomsday Villain: She's powerful enough to be a threat to the entire world, but she doesn't have any motivations beyond causing "Evil". She even admits as much.
• Loss of Identity: Over the course of a thousand years, her memories and personality have been completely overwritten by her Pure Concept of "Evil", leaving nothing of the person she once was.
• Mad Artist: She considers herself a film maker and movie buff. Unfortunately, with her power, she's having a blast unleashing monster "movies" on her victims.
• Maker of Monsters: Every monster in the world was originally brought forth by her use of her Pure Concept.
• Me's a Crowd: She is capable of generating multiple copies of her body that function independently as individuals, though their senses remain connected to the main body.
• Perpetual Smiler: She always has a smile of childish excitement in her face, and does a good job making the "childish" part look creepy.
• Person of Mass Destruction: Each of the Four Major Human Errors has a power that nearly destroyed the world before they were imprisoned. Pandaemonium devoured an entire chain of islands with her monsters before being sealed.
• Really 700 Years Old: Though she looks like a ten-year-old child, she has lived for over a thousand years.
• Resurrective Immortality: Whenever she is killed, her Pure Concept automatically activates and spawns a new, undamaged copy of her body.
• Sealed Evil in a Can: For the past thousand years, she has been imprisoned within an impenetrable barrier made of fog. Things can still enter, but nothing can leave.

Mechanical Society

A Person from Japan who was summoned by the Ancient Civilization a thousand years ago and contributed to its collapse before being imprisoned. Their Pure Concept, "Vessel", lets people increase their power by killing enemies and gaining experience, RPG style, but erodes their sense of self until they become mere extensions of Vessel.

---

• Greater-Scope Villain: Of Volume 3. Unlike Pandaemonium, they don't meet the main cast personally, but every threat they come across in this volume was either influenced or downright created by them.
• RPG Mechanics 'Verse: Played in about as cruel a fashion as possible: those who are influenced by the Society gain the ability to "raise their level", which magnifies their abilities whenever they kill someone of sufficient strength. However, this also causes them to see all those around them as bags of XP and seek out ever greater challenges, before being fully consumed and turned into a puppet of the Mechanical Society.
• Tragic Monster: A brief segment in Volume 6 narrated from their point-of-view reveals that, unlike Pandaemonium, they bear no malice towards the world and have no desire to spread destruction. However, they are unable to stop their Pure Concept from multiplying and spreading, and the loss of their humanity leaves them unable to think about anything else.
• The Virus: Their Pure Concept, "Vessel", overwrites people with Pure Colors and turns them into empty shells which Vessel occupies, making them extensions of Vessel.

Dragon

A person from Japan who was summoned by the Ancient Civilization a thousand years ago and contributed to its collapse before being imprisoned. Not much is known about them, beyond that they are dead.

---

• Posthumous Character: Killed 1000 years ago, creating the island of salt.

Ivory

The secret fifth Major Human Error, whose existence was covered up by the Church. They betrayed the other four Major Human Errors, killing or imprisoning them.

---

• Ambiguous Situation: Ivory's power of being able to "bleach" and overwhelm other Pure Concepts is the same sort of description used for Menou's Guiding Force being colorless, as she was somehow "bleached" and made pure. How these two tie together, much less if and how Ivory was even the one to afflict this, is unknown. Just as well, what factor of their Pure Concept compelled them to fight against the other Errors, if it wasn't their own morality, and what actually happened to Ivory in the aftermath of their war is up in the air. As it turns out, she, Ivory, is the god of the Faust, as well as the keeper of the star memories, a record of everyone's memories in that world, including the memories of the lost ones and the most tightly guarded secret of the Faust. She also created Menou in her own image in order to get Akari back and plan her own return to Japan.
• Big Bad: She is revealed to be the one who created the current status quo of the world, and is planning to destroy it so that she and Akari can go back to Japan.
• Playing the Victim Card: She justifies every bad thing she has done to this world for the last thousand years by bringing up that the world ruined her life and that of many other people first by summoning them against their will. Flare is not amused.
• Superpower Lottery: While every Major Human Error has this, Ivory stands out by having a power above even those, which is how they managed to deal with the other four. The "Ivory" Pure Concept has been shown to destroy (or rather, "bleach") everything it's used against, even other Pure Concepts that are otherwise unkillable. Akari thinks it could even kill her for good. Volume 6 reveals that by its own nature, the "Ivory" Pure Concept allows its user to absorb other Pure Concepts, when it's normally impossible to have more than one. This means Ivory can use the powers of all Human Errors on top of her own.
• Taken for Granite: Their weapon, the Sword of Salt, transforms anything it pierces into salt. It stands in the middle of a literal landmass converted entirely to salt, left behind from their war with the Four Major Human Errors as a testament to the destructive power they wielded.
• Unperson: Ivory was erased from all historical records by the Faust, and their role in defeating the other Major Human Errors attributed to Church agents instead.

Others

Mitsuki Mutou

Voiced by: Yūma Uchida (Japanese), Bryson Baugus (English)

A Lost One and Menou's first on-screen victim.

---

• Alliterative Name: Mitsuki Mutou
• Chekhov's Gunman: A post-mortem example. Menou gave him a proper burial. Pandaemonium later finds the corpse and uses it (and the corpses of the knights Menou killed afterwards) to create a new body for Manon, bringing her back to life.
• Decoy Protagonist: The story begins from his point-of-view, (incidentally, the opening scene of Menou recalling her reoccurring dream doesn't specify her as the narrator in the light novel) and for a time it looks like the story will be about him learning to use his ability and become an adventurer with Menou's help. Then he gets very abruptly killed by Menou.
• Drunk with Power: When he discovers he has the power to erase things, his first thought is that he can do whatever he wants in this new world. As revealed later, this is because Pure Concepts slowly erase the original personality of their hosts the more they are used.
• The Everyman: To emphasize that anyone, no matter how normal and innocent, can be transported to this world, be given a powerful ability, and be made a target by executioners. There is even a deconstructive element at play here: Mitsuki ultimately doesn't last very long as — despite having a powerful ability — he really is just a pretty average guy in all other aspects, and such he doesn't really stand a chance against a trained killer like Menou. In fact, he never sees death coming.
• Genre Savvy: Mitsuki, who actually mentions in the light novels that he reads a lot of isekai web novels, not only immediately cottons on to the fact that he's in "one of those stories where someone gets summoned to another world," he's absolutely ecstatic because it means he's not going to be pushed around anymore and have grand adventures... or so he thinks.
• Glass Cannon: He has the power to destroy pretty much whatever he wants, but he still has the body of a normal teenager. Menou easily kills him by stabbing him in the head.
• Power of the Void: Mitsuki assumes when the ones who summoned him say his power is null that it means he doesn't have any powers. With Menou's prompting, he discovered what it actually means is that his power is Null — he has the Pure Concept of Null. Besides having immense destructive capabilities, Menou notes that if a user deepened their understanding of their own power, they could learn to do things like nullify their own death.
• Stock Light-Novel Hero: He's got the utterly generic appearance, the average everyman background, the Genre Savvy nature (extremely common in isekai), an arc of being initially looked down upon before discovering the amazing potential of his incredibly broken ability, and a hot girl hanging around him because of how special he really is. All told, he was an exceptional example up until the knife entered his skull.
• Unskilled, but Strong: Due to being an ordinary high school student and having just discovered his Pure Concept, he's completely helpless when Menou prepares to kill him.
• Unwitting Pawn: Menou effectively used him to gather info and infiltrate in her mission to kill him and Akari as something of a same-age Honey Trap, and he's absolutely unaware of it because of his indignation at being tossed aside by the kingdom.
• We Hardly Knew Ye: He gets killed by Menou in the prologue of the very first volume.
• Wrong Genre Savvy: For a time the story truly does seem like it's going to be a typical isekai adventure with Mitsuki as the protagonist and Menou as his companion/Love Interest... So it's a bit of a shock when his supposed love interest abruptly stabs him in the head and he unceremoniously dies.

Manon Libelle

Voiced by: Manaka Iwami (Japanese), Kristen McGuire (English)

A noblewoman who is the daughter of a native and an Otherworlder. The death of her mother at the hands of an Executioner and the fact that she didn't inherit a Pure Concept power drove her to bitter nihilism.

---

• Back from the Dead: Though she is killed by Menou in volume 2, Pandaemonium uses Original Sin to resurrect her as a demon.
• Cool Big Sis: In a twisted way, she plays this role for Pandaemonium, hanging out with her, making plans to keep her entertained, and enabling her to have fun as she wants (read: destroy and kill as much as she can).
• Dark and Troubled Past: Let's see, witnesses her mother get murdered in cold blood, essentially gets called useless and denied a Mercy Kill by the murderer, thrust into a position of authority as head of a political faction, and had to endure the people she was supposed to be leading calling her useless over her not inheriting her mother's powers. Yeah, hard not to see how she became "twisted" as she puts it.
• Death Seeker: After Manon's mother was killed by an Executioner but Manon herself was spared, she made it her life's ambition to be killed by an Executioner.
• Freudian Excuse: Being rejected by nearly everyone she knows since childhood and then seeing her mother getting killed right in front of her eyes is a great recipe to create a twisted individual.
• Inadequate Inheritor: The entire focus of her arc—while her mother had the potential (albeit unrealized) to become a Person of Mass Destruction, Manon is nothing more than an ordinary girl. As she was only born to begin with so that her mother wouldn't have to use her gift, this is something that makes her rather miserable.
• Killed Off for Real: Is killed by Ivory, in a way that implies she's not coming back at the end of volume 5.
• Living Shadow: After being resurrected as a demon by Pandaemonium, her true form is her shadow, with her body just being a meat puppet she pilots around.
• Luke, I Might Be Your Father: Manon recalls her mother talking about her daughter from the other world who went missing at some point before she herself wound up here, and most of the information regarding personality and interests seems to point towards Pandaemonium being Manon's older half-sister.
• Not Worth Killing: When Manon was a child, Flare killed her mother for being an Otherworlder but spared Manon because she hadn't inherited her mother's power. Manon always felt worthless due to people being disappointed she hadn't inherited a Pure Concept, and being told that she wasn't even worth killing was the final straw that pushed her into death-seeking nihilism.
• Power of the Void: Since Pandaemonium used Mitsuki's corpse to resurrect her, Manon can now use a lesser version of his Null Pure Concept.
