Manga / Parallel Paradise

"I don't know who brought me here or why...but I will definitely defeat the Jealous God who brought so much suffering to both me and this world."

One day at school, Yota sees someone strange entering school. Out of nowhere this being appears next to him and makes him fall from the 3rd floor! But he stops in a strange world, where beings like dragons exist! Yota meets a young paladin, and discovers that he is the only man inhabiting that planet, and that its inhabitants are extremely "weak" to his presence... would this be a paradise?

Parallel Paradise is an ongoing manga by Lynn Okamoto that began serialization in Kodansha's Weekly Young Magazine in 2017. Like his previous works, it's quite open about nudity, and takes it another step forward and has actual sex. It's licensed in English by Seven Seas Entertainment as part of their Ghost Ship imprint.

General Tropes:

• Alliterative Title:
  • The work name.
  • Most of the chapter names are this if they're not Rhymes on a Dime.
• All Just a Dream: After getting bitten nearly in half by a monster, Yota wakes up back in his home world, with his left arm and right leg missing from his fall off the roof. Turns out, however, that it WASN'T just a dream when the Ragged Doll makes another appearance and chucks him back into the parallel world.
• All Women Are Lustful: Lust for men is encoded into their very DNA in the parallel world. Since there's been no men for the past 300 years, the women of the parallel world are incredibly 'weak' to Yota: the slightest touch or even just seeing his bare torso is enough to leave them chomping at the bit for sex. It's likened to an immune system incapable of resisting an unknown pathogen: the girls even demonstrate the development of a slight 'resistance' after being exposed to Yota for a while. Though Rumi is still all-too-eager to mate with Yota when the opportunity presents itself, his presence doesn't reduce her to the same helpless mess that it did the first time they met.
• Ambiguously Human: With her ability to Wall Crawl, casually travel between dimensions, and the fact she's invisible to all but Yota when on earth, Lilia's true nature is a big question mark...that is, if the Ragged Doll actually is Lilia at all and not just something wearing her face.
• An Arm and a Leg:
  • Kai is missing her left arm: in its place is a rough spike of stone. It doesn't hamper her fighting skills in the slightest: she's able to stab right through her opponents using it, and can channel some kind of paralyzing spell through it as well.
  • After taking a fatal wound from Cetus, Yota wakes up in his home world, and finds out his left arm and right leg were damaged so badly in his fall in chapter one that they had to be amputated.
• Back from the Dead: Continuously being thrown out a window by the mysterious figure to return Yota to the fantasy world finally convinces his father that he wants to die and allows him to be taken off life support. The death of his original body causes Yota to drop dead on the spot in the fantasy world, but then the mysterious figure appears and, in a somewhat-different-than-usual manner of casual violence, brings it back to life.
• Bait-and-Switch: At first, Manaka appears to be the competent one between herself and Rino, with the latter just acting like a goofy cheerleader as the former steers the ship. Once Grakos attacks, though, Rino reveals herself to be a skilled warrior while Manaka loses her head and starts desperately praying for wind. Soon afterwards, however, Manaka shows that she's a badass in her own way as she holds out against a colossal storm.
• Beware the Silly Ones: With how goofy she often acts, it's kind of easy to forget how strong Rumi is, killing a wyvern and a terra golem with no real effort, and actually going toe-to-toe with a Kall at one point (though she's overwhelmed by numbers, even one Kall is shown to be a devastating force).
  • In her guise as Arara, Galia is a goofy, cheerful Sexy Jester, and as it turns out she actually IS a total klutz. She's also a sadistic, cannibalistic witch with an impenetrable Deflector Shield and the power to shred people's heads off from across the room a-la Elfen Lied.
• Brainless Beauty: Rumi may have a good heart, but she's far from the brightest, as Yota laments. She's not dumb by any stretch, but trying to learn math burns her out quickly.
  • Inverted with Hanahana, who is every bit as voluptuous as Rumi but takes to Yota's math lessons like a duck to water.
• Body Horror:
  • When the girls' moons breaks off, they begin to melt from their skins to their bones, leaving only their clothes they wear after they die. Yota sees this first hand upon seeing Haru's death.
  • Kai gets an even grosser variant when she starts dying from pushing her body too far in her fight with the gang, combining the aforementioned melting with Rapid Aging before the rising sun blasts her to dust.
  • Yota's injuries from falling out the window start to add up: the first time, he loses An Arm and a Leg, and when he returns to the real world again after drowning, he's in a full body cast barely clinging to life.
• Bunny-Ears Lawyer: Manaka and Rino are silly to be sure, but Rino is an expert with her Precision-Guided Boomerang while Manaka puts up a valiant fight against a raging storm, managing to outmaneuver a series of huge waves that by all accounts should have sunk them on the spot (she's finally overwhelmed, though).
• Butch Lesbian: Kai looks rather masculine and enjoys taking advantage of Pinako's naivety to have sex with her. She may be Ambiguously Bi with her intent to mate with Yota before killing him and the reveal that she mated with a man 3000 years ago.
• …But He Sounds Handsome: "Galia is a really scary witch! Apparently she's lived for over 3000 years!(...)It's said that even among all the witches, Galia is the most powerful and brutal!" Bit full of yourself, eh Arara?
• Can't Hold Her Liquor: None of the characters seem to hold it very well. Yota passes out after one glass.
• Casual Kink: It turns out that Yota is a bit of a sadist: during sex he enjoys verbally humiliating the girls and watching their reactions. But he never goes further than pointing out how undignified they are in the throes of passion and, again, this is just in the bedroom: he's at his core a good man who's bound and determined to break the Jealous God's curse because it's the right thing to do, and as shown during the fight with Cetus he'd die for the girls.
• Catchphrase: Maya has "Your lack of knowlege is truly beyond help."
• Celibate Hero: Leighmary feels nothing but dissapointment when she sees her garrison throwing itself at Yota with a bit of prodding from other characters. She's never even touched herself before she very reluctantly gives herself up to Yota to be spared her Moon-Breaking, as everyone including herself agrees she's far too strong a potential ally to let her suffer such a fate. Even then, she's able to tell him off at first, and it's Yota who comes back to finish the job when she regrets sending him away.
• Cerebus Syndrome: The story at first is a relatively-upbeat ecchi Isekai series. When the characters reach Sandrio, however, shit gets real. The wish-fulfillment aspect of the story falls apart quickly once Yota is reduced to the Lust Object of the girls of the city, being tied down and gangraped. Then comes the reveal that the parallel world is a post-apocalyptic Earth. And then Galia shows up.
• Claimed by the Supernatural: The girls who have lost their virginity are signified by their neck marks, except, for some unknown reasons, Lilia and Hanahana. Hanahana also lacks the ability to see Noa or resist Kai's paralysis attack unlike the other non-virgins.
• Clingy Jealous Girl: Despite understanding that Yota mating with other girls is unavoidable and oftentimes for the best, Rumi sure as hell doesn't like it.
• Cloudcuckoolander: Despite her stoic demeanor, Tia's thought processes can be...weird at times: the shrimp dance, for one.
• Chick Magnet: By virtue of being a man in this world, Yota is almost completely irresistible to any woman who is aware he is male, and any female he touches will be overcome with arousal.
• The Comically Serious: Tia keeps a straight face even when her body reactions tell a different story.
• Cordon Bleugh Chef: Misaki has made such delightful dishes as werewolf sashimi, which was so disgusting that even this manga decided to give it a mosaic censor. Despite the gross nature of her dishes, they're apparently incredibly tasty...at least according to her.
• Covert Pervert: Lilia may act properly, but she's easily the most perverted of the girls Yota meets, and the most eager to mate.
• Crapsaccharine World: The ladies of the parallel world may be ready and willing to jump Yota at the slightest touch, and it's referred to as a paradise, but a bit of digging reveals that it's a sick, sad world at its core: besides crawling with murderous monsters, the women are cursed to die horribly when they turn twenty thanks to the curse of a god, and the aforementioned god has at least one immortal, psychotic follower going around slaughtering innocents at her leisure. Yota's slow descent into sexual sadism and his increasing jerky tendencies towards the girls (since he's stuck in a world where he can have most of them at his disposal with enough contact and manipulation) isn't looked over either; Nishina reveals that every human man that's been there eventually turned out that way. It's not for nothing that Yota decided something had to be done about it: despite the temptation, what's happening in this world is too wrong not to do anything.
• Curse: Apparently, 3000 years ago, the Jealous God cursed this world's humanity, exterminating all the men and condemning the women to die at the age of 20 if they don't mate.
• Cute and Psycho: Remember the ragged doll creature that threw Yota out of the window? In chapter 60, it turns out to be Lilia. And she's doing all of this because she loves Yota. Yeah, she's got a few dozen screws loose.
• Cute Clumsy Girl: Arara is seemingly incapable of taking three steps before tripping over her own feet and falling flat on her face. It's not an act, either: The Dreaded Galia, mightiest of the Jealous God's apostles, really is that much of a klutz.
• Deus Sex Machina: On top of breaking the curse, having sex with Yota comes with a few other perks as the girls learn, such as the ability to ride bicorns (though that comes at the cost of having unicorns hate you), see spirits like Noa and immunity to Kai's paralyzing spell.
• Didn't Think This Through: Okay so Youta basically raped Nakuta to remove any reason for her to follow the Empress's orders. He decides to release her from the dungeon afterward. Ill-advised, but fine. However, instead of having the guardians of Sendorio do it, while armed, and with her under constant watch, he goes to release her himself, alone, unarmed, with no backup forthcoming. He's then actually surprised when she punches his lights out, kicks the shit out of him, and threatens to kill him anyway, and it's only then that he realized that releasing a powerful warrior he sexually assaulted, and assuming she had no reason to kill him, was probably not the brightest idea he had. The only reason he isn't dead is because she decided to not take revenge.
• Distressed Dude: After their boat sinks, Yota wakes up in Sandrio, chained to a bed getting gang-raped by women desperate to break the curse on them. When he attempts to escape, the ringleader makes it quite plain that she won't hesitate to hurt him if he gets any funny ideas.
• The Dog Was the Mastermind: After hundreds of chapters, the gang comes out to find the Jealous God is...a boy Yota knew in high school who was only mentioned twice before in flashbacks.
• Does Not Like Men: A common sentiment in the parallel world, thanks to the Kall roaming around killing everyone they come across. Misaki nearly kills Yota on the spot when she learns he's a man and Rumi acts much the same in the first chapter, though less openly violent and more afraid.
• Double Standard Rape: Female on Male: Inverted. The girls of Sandrio Town are introduced gang-raping Yota because they know doing so will free them from the Jealous God's curse, which is rightly regarded as horrible. On the other hand, the series takes a long time to address the broad Questionable Consent issue that the girls of the world will literally die unless they have sex with him, and even those who don't already like him beforehand are usually desperate enough to swallow their pride. To say nothing of what happened with General Nakta.
• The Dulcinea Effect: Yota has a major case of this: his quest was started by his disgust over the curse laid on the girls of the parallel world, so much so that he's willing to risk his life hunting down a Physical God in a world filled with ferocious monsters and worse to save them all. This even extends to people like Erza, who had been torturing him mere moments before her moons broke: one minute Yota was glaring at her after punching her across the room, the next she was melting and Yota was horrified and frantic to save her.
• Everyone Has Standards: Despite well-justified anger toward Erza, Yota is horrified when the curse starts to claim her: it's too cruel a fate even for her.
• Evil Is Petty: Kanejou apparently made Yota's life a living hell before either of them got sent to the "other" world. Just why did he sexually assault Nishina and brutalize Yota's mother? Yota scored one legitimate point off of him in a kendo match even when Kanejou blatantly cheated, and Kanejou can't stand that he lost to someone who doesn't even care about kendo all that much.
• Exact Words: Yota bets Nakta that if she can go one minute with him touching her without making a sound, he'll give up trying to convince her to mate with him. She agrees... and then immediately loses when he touches her clitoris with his tongue.
• Expy: Visually, Haru is similar to Lucy: red hair over one eye, a similar facial structure and constantly having an incredibly intense look in her eyes.
• Fantastic Arousal: Merely touching Yota sends the women of the world into ludicrous levels of arousal but it's also stated that it feels absolutely amazing when it happens.
• Faux Action Girl: Zig-zagged. The girls are all demonstrably skilled with their weapons, but they've been bailed out of tight situations on multiple occasions by the far less skilled Yota. There are usually extenuating circumstances to explain this: sometimes they're distracted and caught off-guard, sometimes Yota has outside knowledge of their foe giving him an distinct advantage (the creatures of the parallel world boast uncanny similarities to common RPG monsters, and Yota's a gamer). Regardless, the girls are overall much more skilled combatants than he is.
• Faux Affably Evil: Galia takes her jester imagery and plays it to the sadistic hilt. She grins and giggles cutely as she slaughters and eats people, her tendency to keep her word is just another way to rub in how much stronger she is than everyone else (and often comes with loopholes to boot), and the moment something manages to get under her skin her mask drops to reveal the hateful, murderous witch underneath.
• The Final Temptation: In the form of an orgy with the Quintet (sans Haru). For a moment, he seems content to just stay where he is, making love to the beautiful warrior women he's won over...but the end of the chapter reveals he chose his duty over his desires and is preparing to hunt down the Jealous God.
• First Girl Wins: Rumi is the first girl Yota encounters in the parallel world, the first girl he makes love to, and the two share a far closer bond than the other girls who Yota beds later on.
• Forced Transformation: Nakta is subjected to a horrific case of this by the Empress through a spell, reconstructing the poor girl's Amazon-like beauty into a dirty piglet with an ugly bald human head where it's normal head would be, complete with her normal eyes. All talented enough Guardians are apparently cursed with something similar, including Leighmary.
• Geeky Turn-On: Hanahana's honest attempts to become smarter endear her to Yota, seeing her as this world's equivalent to a cute honor student character.
• God Is Dead: In chapter 29 Yota is told that the Jealous God is, in reality, long dead. It's a big fat lie, and it's later revealed that the one who told him that answers directly to said god.
• God of Evil: Between the genocidal death curse on humanity and the cult following it that employs such delightful people as Kai, the Jealous God is shaping up to be this. Turns out he's not. It's not even a 'he'. It's not even a god. It's not even sentient. The Jealous God is a machine, with none other than Nishina cryonically frozen as its core. SOMEONE BUILT THE DAMN THING.
  • Then, it turns out, that's not the real Jealous God at all. At first, they thought it was Nishina herself, but she's just a witch. No, the real Jealous God (as far as we know at this point) is Kanejou, Yuta's enemy from his old life and the man that assaulted Nishina and killed Yuta's mother. Kanejou is also implied to be the man who first appeared 3000 years before the current setting and turned all of the setting's women into his personal playthings.
• Green Around the Gills: Rumi gets sick and throws up immediately after their ship starts sailing. It's funny at first, less so when her seasickness prevents her from fighting Grakos effectively.
• Groin Attack: Yota comes within mere centimeters of one mid-lovemaking with Vanille courtesy of the scythe-wielding Erza.
• Hate Sink: Even the most vile of the antagonists has at least one character trait that leavens their villainy. Kanejou has none—he is a petty bully with a Hair-Trigger Temper, zero remorse and no hesitation to get violent and every scene featuring him emphasizes his brutality.
• Head-Turning Beauty: Even by the series' standards, Leighmary, the World's Strongest Man of the Guardians, is dizzyingly gorgeous, to the point where Yota initially mistakes her for a High Elf and is immediately smitten by her.
• Heart Is an Awesome Power: Chapter 64 marks the first time Yota actually exploits his Living Aphrodisiac abilities against someone: one touch reduces Vanille to a gushing, weak-kneed mess, allowing him to take her guns away from her. Unfortunately, she manages to stop him from escaping regardless when she clings on to him, begging at full volume for him to mate with her: the sound brings Erza running and Yota is tossed back in his room.
• Heel Realization: Yota realizes just how far he's fallen when Nishina confronts him after he mates with Mei, telling him that he disgusts her so badly she wants to kill him and storming out. The next day he prostrates himself before Mei and begs her forgiveness. The chapter is even titled "Return From Darkness".
  Yota: Nishina...I'm glad you're here.
• He Knows Too Much: After Noa's mother reveals that there's a cult of the Jealous God that's been making the other guardians believe it's dead, Kai (its servant) decides to kill everyone in that village to get rid of witnesses.
• Hellish Pupils: Despite being human, Haru has slit pupils like a cat's. The reason behind this is never explained.
• Heroic Sacrifice:
  • Yota thinks that Haru subjected herself to this to show him how the Jealous God's curse works and harden his resolve to break it.
  • Yota shoves Tia and Rumi out of the way of Cetus's bite attack and gets the left side of his abdomen torn off. He gets better: he wakes up on Earth, and upon his return to the parallel world his wound is gone.
• Honor Before Reason: After seeing Misaki mating with Yota, Haru refuses to follow suit, choosing to die from the curse rather than debase herself. She permits Yota to touch her on the cheek as she passes on, though, and admits it feels great.
  • Momo condemns Yota's desire to risk his life attempting to kill the Jealous God as this, calling him foolish for doing so as opposed to staying with the Quintet from then on. It's not like she's worried he'll get hurt or anything...
• Hotter and Sexier: Definitely compared to Lynn's other works, which were fairly abundant in fanservice to begin with.
• Humanoid Abomination: The Kall have the voices and basic shape of human men, and are violent, extremely powerful demons that even the elite warriors of the cities are leery to fight. They also attempt to inject poison into any female they capture.
• Hypocritical Humor: Despite Rumi telling Yota to not call Genius (an apparent god) a bird, she does the same shortly after.
• I Know Mortal Kombat: Downplayed: there's a world of difference between kendo and actual swordfighting, but it's enough for Yota to kind-of-sort-of know how to use a sword. He's leagues behind people like Rumi, but he can defend himself if it comes down to it and has actually saved her on occasion by attacking a distracted enemy.
• The Immodest Orgasm: The girls on this world have very little self-control while mating.
• Inelegant Blubbering: Rumi's a bit of a crybaby, but when she tries to bid Yota farewell as he heads out on his journey to kill the Jealous God, she's bawling so badly she can't get her words out: tears, sweat, drool, snot, the works.
• Innocently Insensitive: Rumi is furious when Yota tells her that she isn't going to die young after they mate and accuses him of only doing it out of pity. Yota sets the record straight:
  Yota: I'm happy...that you think so much of me. It wasn't anything like pity: Rumi, I mated with you because I wanted to. So I don't want this to be once only. Let's mate again and again.
• Insecure Love Interest: Yota has a mild case of this: being a Living Aphrodisiac, he has nagging doubts as to the true nature of the girls he interacts with, not knowing if his presence is affecting them and making them say or do things that they wouldn't otherwise, and if they actually consider him a friend or not. Hanahana's musing about the topic don't help matters. In the case of Rumi, however, it's evident to both of them that the love they share is mutual and genuine.
• In-Series Nickname: Downplayed with Yota: he mentions back home that his nickname among his friends is "The Sun": it's a pun, being the kanji for his first name backwards.
• Invisible to Normals: Noa is a mysterious little girl that can only be seen by men and non-virgins.
• Jerk with a Heart of Gold: Yota's attitude can be somewhat unpleasant at times, particularly his Deadpan Snarker attitude and willingness to take potshots at the girls if they give him cause to. Regardless, he's at his core a selfless, gallant individual who cares for others and wants to do the right thing by them, even individuals like Noa who he promises to help after just meeting her scant minutes before.
• Jizzed in My Pants: A touch from Yota is usually strong enough to make a girl squirt, and it happens with surprising frequency.
• Jumping Off the Slippery Slope: Yota's morality gets muddier the longer he's active in this new world. It hits its crescendo in Alslayer, what with Yota practically raping Nakta to make her a non-threat, forcing Rumi into heat then forcing her to give him a blowjob just to shut her up, then manipulating Mei into having sex with him, despite Mei being so innocent she doesn't even know what sex is, by promising that doing so will keep her from dying due to moon break, even though that's not necessarily the case, and he knows it, all while he's literally gloating internally about it while the poor girl is falling apart in front of him due to her fear of her own mortality. Yota then takes the extra time to humiliate Mei, just for the hell of it, while embracing the newly appreciated freedom to get as much sex for himself as this world is willing to provide him. Lo and behold, the black collar signifying that that she will no longer die due to moon break doesn't appear. The sad part is that Yota was already warned that the previous man who came to this world was a monster who basically screwed every woman he saw and treated them like his toys, and Yota seems to be following the same path. He does get a "The Reason You Suck" Speech from Nishina that shocks him to his core, and afterwards he seems to be trying to keep himself grounded again.
• Just Following Orders: General Nakta justifies her attempted purge of every girl in Sandrio who had sex with Yota by saying the Empress commanded her to do it.
• Katanas Are Just Better: No they're not. Yota may carry a katana with him for self-defense, but he never gets to use it in an actual fight: the first time he draws it on the Kall, they flee at the sight of him and he doesn't have the chance to fight. Thanks to the elemental barriers of Cetus, the katana just bounces off of her: he ends up using Rumi's Caliburn to fight the beast when the others are incapacitated. This is zig-zagged though, in that his original katana is just an old castoff, and barely useable. He later gets a much better sword, made with rare material, also in the form of a katana, that promises to be far better. It later proves to be so when it cuts Morningstar in half.
• Kill the God: Yota's goal: kill the Jealous God and break the death curse the God placed on the parallel world.
• Knight of Cerebus: As dangerous, terrifying and flat-out disgusting as the Kall are, they're ultimately dumb animals and really no issue with Yota around as they run away at the sight of him. Kai, on the other hand, is leagues more dangerous and intimidating and far, far more depraved.
• Lighter and Softer: While it can get gruesome and disturbing at times, the story is more upbeat than Okamoto's other works by several orders of magnitude.
• Living Aphrodisiac: Yota is capable of making a woman horny by simply touching her, and he also tends to lose his mind in the same way the girls do after smelling their fluids, but he's at least more in control. We later learn the feeling lasts long after Yota's gone for the girls, unfortunately. Not even masturbation can satiate them anymore now that they've had sex with him. The one, and only, person this doesn't work on is Nishina, and that's because she's not even like the rest of the girls period.
• Mad Mathematician: Hanahana gets really enthusiastic when Yota teaches her numbers.
• Making a Splash: Kai's powers are Blue element, and she becomes a huge sea monster called Cetus when fighting, capable of launching high-pressure blasts of water from her mouth.
• Mate or Die: Women in this world will die by the age of twenty unless Yota has sex with them, hence his quest to find answers and break the curse.
• Meaningful Appearance: All guardian girls have a pair of small spheres they call moons on each side of their heads. They shatter when exposed to pheremones released when they are about to reach their limit.
• Medieval Stasis: 3000 years of everyone dying at a young age has made the culture of this world stagnate, as it's that much harder for anyone to gather enough knowledge to pass on to the next generation. It's gotten to the point they can no longer understand written characters.
• Megaton Punch: Rumi socks Yota in the face when he makes fun of her for hiding her head in a tree trunk to cover up her embarrassment...forgetting that she was Going Commando and thus presenting everything.
• Mortal Wound Reveal: A hilariously perverted variation of this when Kia makes a deal with Yota to avoid mating with him: if he touches her and she gets aroused, she'll mate. If not, she'll give herself up to Galia. Yota touches her: nothing happens. Kia calmly turns around, stepping forward bravely to meet her fate...and leaving a trail of her 'springs of lust' in her wake. Then she crumples to the ground and starts frantically masturbating in front of everyone.
• Morton's Fork: Grakos's assault on the ship ends up being this for the heroes: Yota has to choose between starting a fire at sea (a really bad idea) to drive the monster off or letting the thing kill them all. He chooses the former, and the sails ignite, stranding them all in the middle of the ocean.
• Nerves of Steel: Tia's attempt to touch a bicorn has the horse scream in her face with a horrifying expression. She doesn't even flinch. The same thing happens again a few minutes later, with the exact same response.
• Negated Moment of Awesome: Rumi cleaves through all of Grakos's tentacles in one magnificent swing, and for a moment it looks like she and Rino may be able to drive the beast off together...but then Rumi's seasickness hits her full-force and she collapses to the deck, puking.
• Netorare: Yota once tries to mate a lesbian couple in order to collar them. The scene is played out exactly like a netorare scenario, where one girl is restrained and forced to watch her partner be mated by Yota, all while the latter girl insists she won't give into lust and remain devoted to her lover. She breaks very easily and turns into a sopping mess for Yota, and the one restrained threatens to kill Yota for this before being mated herself.
• Nightmare Fuel Station Attendant: Momo of the Quintet has a somewhat twisted personality, saying and doing rather unsettling things with a serene little smile on her face: suggesting without any apparent hint of irony that the girls should crucify Yota to the city walls as living Kall repellent, for one.
• No Immortal Inertia: Witches rapidly age when out of energy or dying: it's initially shown with Kai after she empties her magic reserves fighting Yota and the guardians. Later, Galia meets the same fate: when Yota hits her weak point, she's forced out of her One-Winged Angel form and appears as a wrinkled old hag before collapsing into a puddle of sludge.
• Non-Indicative Name: Sayuri the saleswoman from chapter 3, despite being called a rogue-elf, its actually a Cat Girl. Naturally Yota points it out.
• No-Sell: Cetus is immune to Blue (water originated) weapons by virtue of being a sea monster. Rumi's sword on the other hand is of White element, meaning she can harm it. On the flipside, Cetus's elemental attacks cannot damage Blue weapons, which lets Tia protect Yota from Cetus's Breath Weapon using a comparably flimsy trident.
• Not So Invincible After All: Before her invasion of Meese, Galia is portrayed to be practically invincible due to her shield blocking any attacks done on her. Then she invaded Meese, and one of Rumi's replacement, Nagomi, managed to shatter this by piercing her defense due to her Flash Step and attack Galia when Galia's prepping/launching her spell, revealing that the shield drops during that time. Too bad that Galia, after getting her head cut off, proceeds to transform herself into a giant sandworm, necessitating Nagomi to sacrifice herself to feed Galia in order to stop further rampage.
• Not So Stoic: After mating with Yota, Tia shows a barrage of embarrassed expressions, heavily contrasting her serious demeanor earlier.
• Offhand Backhand: Misaki kills a werewolf sneaking up behind her with a casual backwards stab to the chest, not even sparing it a second glance.
• Older Than They Look: Pinako maybe 18 years old, but she looks no older than twelve according to Yota. And then there's Kai and Noa.
• Old-School Chivalry: When Yota saves a distracted Rumi from a lizard and she demands to know why, he simply answers there's no reason: it's a man's job to keep girls safe. This proves to be too much for the already turned-on Rumi and she pounces on him.
• One-Gender Race: The women of this world haven't seen a human male in centuries, so they're almost this. They apparently are born at a castle in the center of their kingdom, but have no memories of when and how they're born.
• One-Hit Kill: All monsters, even the colossal terra golems, have weak points that cause them to disintegrate when struck. This applies even after death, as shown when Yota stabs a dead werewolf in the throat and destroys its body. Part of what makes the Kall so scary is that on top of being Lightning Bruisers, the location of their weak spot is random between the holes on their faces, meaning that even if someone manages to pierce their guard there's only a one in four chance it'll work.
• One-Winged Angel:
  • Kai turns into the monstrous Cetus in order to kill Yota and the guardians for finding out the truth about the Jealous God.
  • Galia's monstrous form is a huge snake-worm thing capable of burrowing underground and devouring humans in a single messy gulp.
• Our Dragons Are Different: Galia's One-Winged Angel form isn't a sandworm: Yota notices it has arms, horns and scales, and bets the farm on Galia being an Eastern Dragon. His hunch turns out to be correct when he attacks the fabled 'reverse scale' that dragons are said to have beneath their chin that serve as their weakness, and succeeds in killing Galia.
• Our Gods Are Different: Most gods of the Parallel World look like adorable plush toys, and when they speak, it's presented with jet-black word bubbles, whatever that's supposed to indicate. The limits of their power is unclear, though there was little Genius could do to stop Rumi from throttling him in frantic embarrassment, and Vulcan outwardly admits that Galia could kill him effortlessly, so they don't seem all that powerful. But then there's the Jealous God, who was capable of casting a catastrophic death curse on humanity and empowering his followers with immortality and other powerful abilities, and if Maya's words are anything to go by he would be nearly unstoppable should he wake up... until we learn that the Jealous God isn't a god at all: it's a machine with Nishina as its core. Then, it turns out, the machine isn't the real Jealous God at all. The real Jealous God (as far as we know at this point) is Kanejou, Yuta's enemy from his old life and the man that assaulted Nishina and killed Yuta's mother, who was originally a normal human being.
• Our Mermaids Are Different:
  • Cetus is a hideous mishmash of a troll and a large canid beast with a long fish tail for hind legs.
  • Noa and her mother on the other hand look like typical (and much prettier) mermaids.
• Out with a Bang:
  • Kai intends to kill Yota after she mates with him.
  • Yota attempts to save Erza from the curse after her moons break, but even though mating with her prevented the agonizing melting part of it, she still Vanished Into Light as soon as she climaxed.
• Overcome with Desire: It nearly happens on the second chapter, and it goes downhill from there.
• Overly-Nervous Flop Sweat: Tia sweats from the armpits whenever she's embarrassed, which betrays her attempts to look calm.
• Paralyzing Fear of Sexuality: The reason why Amane doesn't speak, and is extremely against mating Yota, even if it's for saving her life (which results in the others girls tying her up and delivered her to his room, twice) is because she was ashamed of herself getting aroused by the Kalls raping her friends to death. She does eventually comes around, however, and gives herself to him willingly.
• The Pirates Who Don't Do Anything: Rumi's a subdued example: despite being The Paladin, she doesn't really DO anything that fits that role besides happening to wield a White-element weapon. She's not particularly religious, and the god that could have been her patron (Genius) doesn't get a lot of interaction or for that matter respect from her. She doesn't even fit this as a Character Class: she's shown no magical aptitude. Regardless, all of this doesn't make her any less badass once she starts swinging that sword around.
• Porn with Plot: Let's just say Yota having a lot of sex is necessary for the story to advance. As the story progresses and the twists and Wham Episodes start to pile up, it flips to Plot With Porn.
• Precision-Guided Boomerang: Rino uses one as weapon, and it can easily slice the tentacles of the Grakos.
• Pride: Galia's Fatal Flaw. Despite having multiple chances to kill Yota and the others, she chooses instead to sadistically torment them and the citizens of Meese, entirely secure in the belief that she's invincible. This gives Yota and co. plenty of time to figure out her weaknesses.
• Rape by Proxy: Yota gets forced into it twice. The first time is when the Guardians of Sandrio force him to mate with multiple women in the city to break the curses on them. The second time is when Galia forces Yota to have sex with Katsuchi in order to save the world. In this case, Galia also forces Katsuchi to have to evacuate her bowels and bets the salvation of humanity on whether or not Yota can ejaculate inside of her before she shits herself. Yota cleverly wins this little game switching to anal midway through the copulation to prevent Katsuchi from having a bowel movement before he finishes. Unfortunately, his penis goes limp when he's done and Katsuchi still needs to go (and Galia refuses to release her from the magical bonds that were holding her up) so...
• Really Gets Around: By chapter 25, Yota has mated with four different girls, and it only escalates from there.
• Respawn on the Spot: When Yota dies, he gets sent back to his time with some injuries. Reentry into the fantasy world involves him bringing himself to critical condition, but he respawns in the world just before his time of death. The story makes clear that he can't just do this every time, since every death brings his original body closer to becoming immobile. Eventually he's effectively on his last life, as his parents have taken his original body off life support.
• Questionable Consent: Present throughout the series since the girls will literally die unless Yota penetrates them at least once (chapter 104 confirms that a single thrust is all it takes to lift the curse), though for the first hundred chapters or so it's usually pretty clear they would have slept with him anyway. Not so General Nakta, who is being held prisoner by Yota and Sandrio Town after she was captured while trying to kill him and every girl who ever slept with him (she beheaded three): with his Battle Harem's help he first gropes her to weaken her on the battlefield enough to be captured. Then while she's being held prisoner, he tells her the arousal will only go away if she has an orgasm, and since she's tied up she can't masturbate, but he'll still only have sex with her if she explicitly asks for it and then spends the rest of the chapter browbeating her into doing so. Given what she planned to do to the town, it comes off as Karmic Rape.
• Samus Is a Girl: The series spends so much time focusing on the Lady Land aspect that it never dawns on Yota that the Jealous God could turn out to be male. And indeed, none of the people who know about the God refer to them with either male or female pronouns. When time comes and we see the real god, they are indeed a man.
• Single-Stroke Battle: One in Chapter 85 that probably counts as the most ridiculous example in the history of Manga: Yota challenges Amane to a duel so he can mate with her. Her weapon, her sword. His weapon, his bare hand. In one swift movement they clash: Yota dodges the blade and gets cut on the cheek, while he manages to touch Amane's face. Down she goes.
• Situational Sexuality:
  • It has been confirmed in chapter 31 that since there are no men around, girls turn to each other.
  • Chapter 104 delivers a practical example when Rumi and Amane start comforting each other, when Yota is "busy".
  • Chapter 144 gives us another example when a flashback shows the current guardians of Alslayer as children walking in on two older guardians having sex with each other, despite knowing the children are there.
• Slap-Slap-Kiss: As much as Yota and Rumi care about each other, they squabble a lot, and Rumi's given him his fair share of Dope Slaps and Megaton Punches.
• Spanner in the Works: Yota's very presence throws Kai's entire operation out of whack: for some reason, he and the girls he mates with are able to see Noa, and in helping her they learn enough about the Jealous God to force Kai out of hiding so she can kill them and keep the God's existence secret. Despite having spent hundreds of years keeping weapons that can harm her out of Lille, Kai couldn't have forseen Rumi's Caliburn coming, and thanks to Yota's knowlege of mythology and quick thinking, Lille is ultimately freed from the evil bishop's grasp.
• Squishy Wizard: Galia, at least in her human form. Despite an impenetrable deflector shield and devastating magical blasts, if anyone manages to land a hit on her she has no real way of recovering, since her shield drops every time she attacks; any attempt she makes to counterattack just gets her smacked. Once she goes One-Winged Angel, though, all bets are off.
• Starter Villain: Kai: a 'bishop' of the Cult of the Jealous God, and the first thing the characters face directly related to said god.
• Supreme Chef: Tia loves good food, and by extension she loves to cook, and she is damn good at it.
• Surprisingly Realistic Outcome: Everything that happens in Yota's home time. His parents and the doctors eventually surmise that his insistence in throwing himself out the window every time he's able means he's been traumatized from his initial incident and deeply suicidal. His parents come to the conclusion that his 'attempts' are really just his way of telling them to take him off life support, and given his injuries have reduced him to all but his brain functions, they reluctantly oblige.
• Sympathy for the Devil: Despite everything she had been doing to him mere minutes before, Yota is horrified when the curse starts to kill Erza, and though he convinces her to mate with him in a last-ditch effort to save her, it's all for naught. When Vanille bursts into the room, she finds a clearly-distraught Yota sitting silently by Erza's empty clothes.
• Taken for Granite: After Yota returns to his world, he deduces that Cetus only comes out at night because it turns into stone with sunlight. He turns out to be right on the money: the sun comes up, Kai turns to stone and crumbles into dust.
• Teenage Wasteland: While the society of the parallel world is holding up alright, upkeep of the architecture is suffering, and education is as well, causing basic things like math to be forgotten because of the population all dying at such a young age. It also doesn't help that the parallel world is Earth All Along.
• Tempting Fate: Rumi does this twice in chapter 3, first she tells Yota the worst thing it could happen to him is stepping on bird poop, next panel she steps on lizard poop. She also tells him not to touch any other girl, and unsurprisingly he touches Lilia by the end of the chapter.
  • On a more serious note, when Yota worries about sea monsters' attacks, Makana assures him monsters won't attack their ship, with the exception of the Grakos that only comes out when there's no wind. The wind immediately stops.
• That's No Moon: One of the two moons in the sky isn't a moon at all: it's SOMETHING'S colossal, glaring eye.
• The Cake Is a Lie: Kai has sex with Pinako under the pretense she can stop her moon-breaking, something she's incapable of.
• Their First Time: Rumi and Yota have their mutual first time.
• Theme Twin Naming: There's the twins Mona and Lisa.
• Through His Stomach: Tia clearly enjoys having her cooking praised by Yota, and as he leaves for Sandrio she makes him promise to come back so she can cook for him again.
• Token Good Teammate: Sanya is the first mildly-good witch we see in the story, and as more is revealed about her she surprisingly becomes more heroic. In contrast to Kai and Galia, she's willing to make bargains with humans, and personality-wise she's affable, if a bit of a cranky old lady. Despite being the one to tell Mimi how to become a witch, that is to say, eating the flesh of humans, she never imagined Mimi would actually be deranged enough to take her up on the suggestion: she was lying about it to begin with, and only told her something so gruesome to deter her from pursing witchhood. Even after restoring Nishina's memories, she declines to eat Mimi's brain as payment and decides to simply let her go.
• Trapped in Another World: Yota isn't sure how he arrived to this world, but is willing to make the best of it.
• Uncertain Doom: For a while, it was unclear whether Manaka and Rino escaped Galia's massacre of The Resistance. The cover for chapter 99 ultimately shows that they did: they're beaten up and wandering the desert.
• Unicorn:
  • Unicorns not only exists in this world, but they're also relatively easy to find in the wild and known to be invariably nice and helpful to travelers. Yota quickly figures out that these unicorns actually behave like the ones from myth in Earth in that the only tolerate virgin girls when the first unicorn he meets rejects Rumi. Her surprise at this also told him that unicorns' fame for friendliness comes from the fact the other world is a Lady Land where everybody dies a virgin, so it's natural for people to assume that's rule rather than the exception.
  • On the other hand a bicorn, a symbol of impurity, takes an immediate liking towards Rumi, who only knew them as violent creatures for reasons similar to the above. This becomes a plot point when another character who knew the myths about bicorns figures out Yota's existence from it.
• Unsexy Sadist:
  • Yota may have a few sadistic traits, like how he points out how undignified the girls are when he mates with them in order to embarrass them, but at no point has he truly dehumanized them or god forbid harmed them physically, and all of the times he's instigated sex it's been consensual. The same CANNOT be said for Erza, who forces herself on Yota against his will, makes him call himself a pig, kicks him and strikes him with the hilt of her scythe, threatens him with the business end of her weapon should he resist, and instigates watersports on the poor kid. Even she herself admits as she dies of Moonbreak that her urges unsettle her, but she simply can't help herself.
  • Galia takes it even further than Erza. Given the choice between forcing someone to debase themselves in front of her and eating them, she chooses the former every time.
  • It's not as if Yota's exempt from this trope as well. As time went on, he eventually became rather cruel and demanding to Rumi and other girls, even forcing a lesbian couple to get addicted to him while they take their turns being tied up watching him. He does feel some remorse, but he's convinced himself that it's all to help them avoid moon breaking.
• Unwitting Instigator of Doom: Amane really did mean well but by being the last person to travel the portal back to Meese to fight Galia, Lilia was left behind in Sandrio which may be the cause her Start of Darkness.
• Weak, but Skilled: Despite having taken Kendo, Yota is far and away the least combat-oriented of the denizens of the parallel world. This forces him to use his knowledge of mythology and quick thinking to defend himself: his battle with Cetus shows this well as he focuses on incapacitating the monster with strikes to her limbs so that she can't escape the rising sun, rather than going for a killing blow.
• Weakened by the Light: Cetus, and by extension Kai, is vulnerable to White, or light element attacks. She meets her end when the gang keeps her from escaping and the sun destroys her.
• Wham Episode:
  • Chapters 48-50 are an extended example of this: Yota is fatally injured by Kai, but immediately afterwards he finds himself back in his world with his arm and leg lost because of his fall. THEN he's forcefully sent back to the parallel world...and his childhood crush Nishina is dragged along for the ride!
  • Chapter 60 is an even bigger example: Yota dies in the parallel world after being shipwrecked and again wakes up in the real world. This time, his body is in even worse shape than last time, with one of his eyes also missing. The masked doll that sent him to the parallel world the previous times is standing right over him. When he asks who it is and why it's doing it, it removes the mask... and it turns out to be Lilia! Nobody saw that coming.
  • Chapter 70 Yota breaks the barricaded window of the room which he is kept imprisoned, seeing Sandrio for the first time: surprise, it turns out the parallel world was Earth All Along!
  • Chapter 80: The Jealous God is a supercomputer in a heavily fortified underground facility protected by a password-locked hi-tech sealed blast door, and at the center of the machine is a naked Nishina in a glass tube!
  • Chapter 250: Lilia's conversation with the moon reveals many things. It turns out that the neck marks Youta's been fighting so hard to get girls to have don't actually do anything for moon breaking; they're actually brands that mark girls for infertility, and the girls who did get pregnant aren't even guaranteed to live after their last moon. Above all, the only way to get the world back to normal is to kill Youta, if only because he's the one thing the God of Deep Jealousy hates above all.
• Wham Shot:
  • More meta than anything, but Rumi crying out in pleasure as she and Yota consummate their relationship gets a full page to itself, as if it's the manga's way of saying 'No, I'm not kidding. They're having sex.'.
  • The huge eye splitting open one of the twin moons glaring down at the oblivious Yota, perhaps our first glimpse of the Jealous God...
  • Yota's first look at Sandrio turns everything he and the reader knew on its head. Yota isn't in another world. He's in the future.
  • The Jealous God is finally revealed. It's Nishina. The Jealous God is Nishina. The Jealous God is Nishina, trapped in a bizarre machine....or so the premise wants you to think.
  • Later on, the gang finds another tomb with the real Jealous God—the boy Yota fought in kendo practice.
• Wicked Witch: Kai, a depraved, cannibalistic woman with magic abilities who secretly holds Lille under her thumb. Galia, another witch under the Jealous God's employ, is said to be even worse, and when she finally makes her appearance, NOPE: not an exaggeration.
• Worf Had the Flu: Rumi's seasickness completely cripples her during Grakos's attack on the ship: she manages one attack on the monster before she keels over, vomiting.
• World of Action Girls: The warriors are only women, so they're this by default.
• Would Hit a Girl: As soon as Yota manages to wriggle free of his bindings, he slugs Erza, who's torturing him at the time, so hard she goes flying across the room.
• Yandere: The reasoning behind Erza torturing Yota: far from disliking him as she previously implied, she's so infatuated by him that she's terrified of just being one more girl he has sex with and then forgets. Her solution is to, in her words, 'carve herself into him' via humiliation and Cold-Blooded Torture.
