Euphoria

"Per angusta ad augusta, per aspera ad paradisum" (through dificulties to honor, through hardship to paradise)

Euphoria is a 2011 H-game, with an Hentai anime adapting it with several liberties released on the same year.

Takato Keisuke wakes up in a white room in the middle of nowhere, wearing his school clothes. He remembers going to bed yesterday, but seems to have been kidnapped during his sleep. Investigating what happened to him, he soon exits the room and discovers that along with him, six females he knows were seemingly also kidnapped: his childhood friend Hokari Kanae, the class president Andou Miyako, his under classmate Makiba Rika, his English teacher Aoi Natsuki, same year Byakuya Rinne, and classmate Manaka Nemu, that weirdly seems amused by the situation unlike everyone else.

Soon a robotic voice talks to them through a loudspeaker, and explain they will have to play a game. A game that will put, at best, one of the girls through hell. Keisuke, however...

Developed by ClockUp.

Tropes used in Euphoria include:

Action Girl: The Woman In Black and Natsuki are very capable in combat. If you play through a certain path in Kanae's route, you will discover they're both one and the same.
All Just a Dream:The end of Rinne's route. After Takato wakes up in a bed in a room inside a house stated to both his and Rinne, where Rinne is watching over him, he says to her that he had a bad dream, she assures that she will always be by his side, and the route just ends after Takato assures himself he don't have to think about the dream after all.
Ass Shove: Oh boy, here we go. In Kanae's route, one of the games have as one of its requirements that Takato must shove a stuffed pig down Kanae's anus , and she must "give birth" to it just after. It's exactly what you're thinking.
Belligerent Sexual Tension:In all routes, but specially Nemu's route Takato and Nemu is a dark, very dark example of that trope, though it's one-sided, with Takato refusing to willingly enter in a relationship with Nemu and acting aggressively towards her while she constantly teases him, but it's clear Takato is fighting very hard to not go into her arms. In her route, he goes as rough he can to make her break and fear him, and in Kanae's route, when Takato tries to kill her by choking, she gets excited.
Birthmark of Destiny: Takato has one on his back and neck that supposedly makes him the "future father of The Messiah" for the ascetic cult that Rinne is leader of.
Child by Rape: In the special bad ending of the VN, Takato repeatedly impregnates his harem of sex slaves, but he don't says or implies what he does to the babies.
The Comically Serious: In a unexpected way, Byakuya becomes this, specially when the "bonus games" are played. Out of simple innocence or because she seems to also lack the capacity to understand emotions, she doesn't understand very well what could make Takato excited aside of his very obvious sadism. Keisuke comments on how that makes him like her even more, because she does things he likes without even being aware of how perverted it looks.
Deadly Euphemism: Nemu refers to death as "The End" when the others characters begin to discuss about executing a Loophole Abuse that would allow them to get the food from the VIP room to the outside, and she is convinced that doing something like that would get all of them killed like Miyako.
Double Consciousness: Takato struggles between his identity as common student and as a sexual sadist in almost each route, trying desperately to try to hide the latter despite the games making him feel better and better each time.
Double Standard Rape (Female on Male): Averted. No jokes are made on Takato being abused and raped both in the VN and in the anime.
Dramatic Unmask: The Woman in Black is finally unmasked in the middle of intercourse with Takato that, severely irritated by her Extreme Doormat behaviour, pushes her gas mask off. Don't gets much more dramatic than this.
Dressed All in Rubber: The Woman In Black wears a form-fitting latex suit. Combined with her gas mask and unexpected agility and stealth for someone of her size, it gives her an otherworldly feeling of mystery and terror, since she seems less like an human and more like a machine.
Earn Your Happy Ending: What the quote on the top is about, and in almost each route Takato and the chosen girl must endure through suffering that goes beyond the white cage to get their happy ending together. We say almost because the Nemu route ends on a cliffhanger, but technically that route continues in the Kanae one where the same as the other routes happen...though isn't Kanae who gets a happy ending.
Eat That: Oh boy, here we go. Certainly one of the softest pornographic scenes of game, and not all that gross, but specially repulsive to Rika. The second bonus game in her route forces her to eat food mixed with...Takato's male essence. She is very grossed out, specially since she looked out to eat all the delicious food with great anticipation before.
Electric Torture: Kanae is put through this in her route by being tied to a chair, with the current slowly increasing to further test her conviction through the torture that the torture itself feels good, with her erogenous parts being given special attention by having electrical components attached to her clitoris, her breasts, and a dildo-like probe put through her vagina. Keisuke has to do the interrogation and the torture.
Eerie Pale-Skinned Brunette: Byakuya Rinne, that along with her behaviour makes her look like an alien, like someone who understands human behaviour but lacks certain traits of it.
Face of an Angel, Mind of a Demon: Keisuke often comments of Nemu's beauty, that contrasts extremely with her cruelty.
Foreshadowing: Nemu suggests Takato to pick the same girl over and over again after the first sex chamber. At first it seems like a lazy in-game hint in how access each girl's route. As it turns out, Nemu is The Mole and is fully aware of what the game involves, so the hint was probably given to Takato in purpose so he would create an emotional bond with the respective girl, a bond that Nemu would try to use to manipulate him later. Or in the case you pick her, so she could corrupt Takato by herself.
Gas Mask Mooks: Or in this case mook, The Woman In Black. It easily marks her as Nemu's Elite Mook.
Groin Attack: Keisuke whips Rinne right in the middle of the legs as part of one of the games. He even mentions the probability of rupturing her clitoris with the tool, and that actually excites him. Yeah, Keisuke is sick young man.
Hair Decorations: Rika has a little bow on the right side of the hair to emphasize her cuteness and youth.
Happily Married: Implied to be Keisuke and Rinne's case in her ending.
H-Game POV Character: Takato is Type II B, but surprisingly verging on Type VI thanks to his sadistic urges. In one bad ending, he goes full Type VI and, oh boy, it isn't pretty. Well, unless you're extremely sadistic too and got off on it.
Hidden Depths: Nemu seems to be a very...perverted girl, much more willing in participating in the game that even the adult Natsuki. If you pick her, however, to Takato's surprise, she is a virgin. And that is just one layer of inconsistency between her usual behaviour and what she actually is...
Hoist by His Own Petard: Rika in two routes.In both Nemu and Kanae's routes, she offers herself to help Nemu in torturing Byakuya, that had organized a revolt against Nemu's rule over the school. She does take part in the punishment indeed. By being attached to a machine where Rinne is also attached that will make them swallow each other's excrements.
Hot Teacher: Natsuki Aoi has a pretty face, nice figure, and quite well endowed.
Instant Humiliation - Just Add YouTube: Or more exactly, NicoNico(since it's Japan). In Rika's route, one of the games involves simple vaginal sex, except that it's being broadcast through the Internet and Rika has to say very embarrassing things to the camera. The game never goes into detail about the implications of this, but the humiliation part is here, just as the nasty comments you would expect from anonymous people in the Internet, floating through the screen.
Irony: The Woman In Black wears a gas mask, that is extremely confusing, since the last thing you would expect in this setting would be someone using gas as a weapon. That isn't irony.The irony is that in one route Takato puts aphrodisiac gas inside the bubble of air between her face and the mask, and closes the mask. What was supposed to protect her from a gas attack now is used to make her breath a dangerous gas. Situational Irony at it's finest.
Late Arrival Spoiler: If you played the game after watching episode 2 of the anime, you will be surprised to discover that Kanae isn't selectable. At first.
Lighter and Softer: The bonus games involve sexual acts that are well less rough that the main chambers, to the point it you could say they are even trying to be romantic.
Like Brother and Sister: In almost all routes, that is how Takato relationship with Kanae ends up developing into, with his internal narration describing him saying "I love you" as of the type which you would say to a family member, not a lover. Except in her own, unlockable route. The reverse is definitely not true, but because Kanae is revealed to be a Jerkass manipulating him in her route.
Light Feminine and Dark Feminine: Nemu and Kanae, specially when taking in account how Takato see them. Nemu is a reflection of his dark personality and sadism, and wants him to drown in his own desires. Kanae represents innocence and naive happiness, and is that how Takato wishes everything to end, even with Nemu keeping to push his buttons.
Love Potion: An extremely dark version of the Love At First Sight variation: it makes you incredibly horny towards the nearest person you see and not even orgasm stops it, but you're basically an euphoric animal in heat until the effect ends, with your mental capabilities greatly reduced, and you think about sex 100% of the time, if the effect ends. It also gives you extreme pleasure during sex.
Madness Mantra: In Rinne's route, Rika screams Rinne's name again and again as she kills herself with a knife after failing to convince Takato to let go of Byakuya. The mad screaming continues as she bleeds and ends as she loses consciousness of loss of blood.
Marry Them All: There is one route that can end this way (yes, despite the fact there's only unique routes if you choose a girl over and over again). It's an alternate end to this route, and even the term "them all" may be stretching: in the called devil/evil/brute ending in Kanae's route, Takato kills Kanae and enslaves all of the other girls, turning them into sex slaves he uses to satisfy his sadistic urges towards women. He even preserves Kanae's body and her organs, though he's not a necrophiliac, he only likes to watch her immobile body(that's just 5% slightly less creepy since he's her killer). Rika and Rinne are pregnant with visible pregnant bellies in the end, but god knows what Takato will do with the babies.
Mate or Die: Takato and the girls are forced to commit sexual acts that vary from soft(literally kissing a girl until orgasm) to outright torture(whipping), otherwise they will be executed. Of course, Takato does feel sexual enjoyment in doing everything even if it doesn't seem that sexual, like whipping Rinne or giving Rika laxative and watching her,uhn...do an embarrassing bodily act.
Never Found the Body: Andou Miyako's is never stated as dead in the game. Her dying body just disappears from the electric chair room after the events of the first sex room, no matter who you choose. Is something even her VA brings up in the extras.
Nightmare Fetishist:
- Takato gets aroused at the vision of Miyako dying on the electric chair, that he knows that is dying.
- Nemu is no better, and actually takes a liking to him because he's getting aroused for Miyako's suffering. And we're saying no better because she clearly is taking an enjoyment at all the rape and depravity that happens in the school under her rule.
- Actually averted by Byakuya. She wants to be punished, but has nothing to with sexual pleasure: she believe she's a sinner and being punished by Takato is just something she thinks she deserves.
No Ending:
- If you choose more than one girl to enter the sex rooms to have sex with Takato, in the end the characters escape from the white room complex and discover they are very near of their school. Takato and Kanae go to search help and....roll credits..
- Some bad endings end like this, like the ones with Rika. Takato just falls unconscious in the middle of the action and the credits roll, without resolution to the situation.
- Nemu's route itself. Seeing that Takato don't gives in to his sadistic urges and don't wants to kill Kanae, Nemu let her be raped and even possibly killed by the other students and imprisons herself and Takato in the gymnasium, even swallowing the key to prevent him from going for her rescue. Takato tries to choke her to death in revenge but stops, unable to kill Nemu. He gets apparently stabbed in the back and the last image we see is Nemu crying over Takato's dying body. What? This,however, ends up averted if you get deep enough in Kanae's route, that is unlocked after the Nemu's route.
Not So Stoic: What Takato wants to cause to Rinne through extremely sadistic sex in her route. He does manage to finally make her show emotions...but not by torturing but by giving her pleasure instead of pain.
Rape by Proxy: What the whole thing is and the majority of the girls believe to be, since they have to have sex or die, but Takato seriously doubts it because he likes it. Apparently he never heard that sexual excitement and orgasms don't equals consent, which gets specially ironic when one of the "games" involves constantly stimulating a girl with a magic wand until she have 10 orgasms, and Takato and the players can see clearly how prolonged stimulation of sexual pleasure can be used as torture as the girl goes mad with pleasure.
Rewarded as a Traitor Deserves: Rika betrays the other players in the game in favour of Nemu in Kanae and Nemu's routes. Nemu lets Takato torture her at the first opportunity she gets later.
Sanity Slippage: Keisuke seems to be always verging on insanity, but it is specially clear on the Kanae's route. As he abuses Kanae, he begins to dream and having hallucinations involving Kanae been killed...by him, as the ultimate torture act. In a bad ending, though not bad from his perspective, he fulfils those desires to its gruesome ending, and goes even further. Though he is able to act normal when not playing with his "toys", he seemed to have gone off the deep end.
Sex Slave: The idea is brought up by Nemu when Takato opens a box in the first room that contains a bondage vest for her to wear, but otherwise seems absent. In a special bad ending in Kanae's route, however, Takato uses all the girls, except Kanae, whom he killed, as slaves: Rika is forced to act like a dog, Byakuya his "work of art" that he tattooed and he constantly whips, Natsuki is his "lewd cow" whose mind has been fried by a powerful drug, and her pleasure nerves were extended to such a point that she is in a constant state of delirious pleasure, and even a slap makes her feel good, and Nemu serves as a trophy in the wall that Takato occasionally uses. The first three are also pregnant, and it is heavily implied that Takato is impregnating them constantly.....Yes, it's that kind of bad ending.
Single Tear: Rinne cries one single tear after Takato takes her virginity by raping her while she's partially buried in cement to the wall of the bathroom of the school in Nemu and Kanae's routes.
Soft-Spoken Sadist: Both Nemu and Keisuke show traits of this, almost to a literal level since they really enjoy seeing people in pain. It is more noticeable in the anime than in the game in Keisuke's case since he have a voice actor. The "soft" part completely disappears when they have sex, obviously. And of course, Keisuke is trying to hide his excitement, so in this case trying to speak softly is a necessity.
Split Personality: Takato defies this trope, even after a particular episode where suddenly gruesome thoughts about Kanae appear in his head to the point he is affected physically, saying that there's no separation between the sadistic part of himself and "Kanae's childhood friend".
Spoiled Brat: Rika isn't a kid, but is treated such as one by everyone, using her cuteness as a way of getting everything she wants. Byakuya and Takato even drop the name of the trope in Rinne's route, and Byakuya proceeds to try to correct her behaviour.
Strange Girl: In her route, as Takato interacts more and more with her, Rinne is shown to be...strange once someone begins to get close to her. She hear voices, believes that the punishment Takato gives to her is a way of absolving her own sins, and in general seems to know more about what's happening than you could think initially.
Teacher-Student Romance: What happens if you choose Natsuki as Takato's partner.
The Chosen One: Sort of. In Rinne's route, Takato is supposed to be the father of said individual. It don't even needs to be one: Rinne makes Takato have sex with several women because she sees no problem with her ascetic cult having several of them.
The Stoic: Byakuya Rinne don't shows a lot of emotions. Even during her sex scenes, it's clear her screams and moans is just her instinctively showing pain. Soon as the sex ends, she turns stoic again.
The Three Faces of Eve:
- Nemu, Byakuya and Rika form such an trio at first. Rika is the innocent one, Byakuya is the mature and smart one, and Nemu is the sexy and seducing one. This even plays in how they take the torture: Rika is extremely reluctant and desperately don't want to be chosen, Nemu is completely willing and in fact welcomes it, while Rinne just...don't care.
- Alternatively, considering their personalities, there's Kanae, Rinne and Nemu. Kanae is the kindest, Nemu the most evil and Byakuya the neutral.
Token Evil Teammate: Takato verges between Anti-Hero and Villain Protagonist, but Nemu is clearly enjoying the game and not even hiding it a little, and in each route, including her own, she stimulates Takato to give in to his sadistic urges.
Token Loli: Rika serves as this, to its sadistic, lolicon-appealing end: almost all her sex scenes involve humiliating or making her suffer in some way, and Takato comments in how it feels good to torture such a young girl.
Troubled but Cute: Takato is the shining champion of this trope. He's a sexual sadist to the extreme, but clearly has deep guilt issues about it and it is shown to be really a kind person when he's not feeling sexual pleasure of torturing girls.
Two Plus Torture Makes Five: Keisuke has to force Kanae to say that she "feels good" as he subjects her to electrical torture as part of one of the games.
Undying Loyalty: Both Nemu's followers and Rinne's cultists follow each of their leaders' orders without questions. In the case of Nemu, because she gives them a hedonist lifestyle (they can abuse any girl she allows them to as much they want). In the case of Byakuya, because they madly believe Rinne's teachings will lead them to "paradise".
Ungrateful Bastard: For all the help that the others characters give her, Rika betrays them all for Nemu after they escape the underground game in Nemu and Kanae's routes, apparently solely because Nemu treated her well in the deluxe room.
Vader Breath: The Woman In Black is a subversion: her role is similar to Vader, and the sound of her expiration does seem laboured, but it seems more a result of the gas mask she wears than anything.
Villain Protagonist: Zig-Zagged. Takato is a sadistic teenager that truly enjoys seeing girls in pain and rape them. However, he states he never did something like that before and the circumstances of the game force him to act like that, so he is technically a victim as much as the girls, as Natsuki brings up. Forcing him to torture girls through sadistic sex acts seems like pushing a bottle of alcohol down the throat of an alcoholic. However, in a possible bad ending, he kills Kanae, allies with the organizers of the game, turns Nemu into a trophy, and enslaves the other girls to a life of constant masochistic sex and pregnancies. That is already crossing the line. However, considering his gruesome hallucinations earlier in the route where this happens, you may say he's too mentally sick to be considered evil.
What Happened to the Mouse?: Something you don't would notice unless you play other routes before Rinne's one. Natsuki/The Woman In Black mysteriously disappears in that particular route for no discernible reason. Nemu even lampshades it by wondering where she is, though you're not informed of what exactly Nemu was waiting to appear. Considering that the route ends in All Just a Dream and its possible implications taken in account other routes, a possible explanation is that Takato simply didn't dream of her in this particular iteration of the dream..
X Meets Y: The premise sounds like someone threw Saw and the works of the Marquis de Sade in a blender with very fast and sharp blades. Grab your vomit bag if you're too weak.....Or enjoy it if you're strong enough.
Zettai Ryouiki: Nemu has a grade A.
