Summoning a demon for revenge sounds cool in theory, right? You light some candles from Dollar Store, mumble a half-remembered chant you found on some shady forum, and expect a dramatic but classy spirit to show up and help you screw over your enemies. Instead, this game hands you a horny vengeance demon who absolutely did not get the memo about “professional boundaries”. You play as this poor human guy who clearly thought he was in some edgy occult story, but the second that circle lights up, it turns into something way closer to “I accidentally ordered a sex-obsessed monster from hell and it’s not accepting refunds”. The tone is very “this was supposed to be scary, why is he licking my neck and asking about my taste in guys”.

What I really like is that the demon isn’t just a generic muscle dude with horns slapped on. He looks wrong in a hot way. Eyes a little too sharp, posture too confident, smile just on the edge of predatory. He’s got this vibe where he talks about tearing out someone’s soul, then immediately pivots into teasing the protagonist about being “tempted already, aren’t you?”. The game keeps mixing violence talk and sexual stuff, like he describes revenge as if it’s foreplay, and sometimes it is actually hard to tell if he wants to rip the bully apart or watch the bully fuck you until you cry, for “punishment”. There are a couple scenes where he sits too close and touches a bit too long, and the art really sells that feeling of “I should not be turned on by this, but I am”. When his claws rest on the MC’s throat during a “friendly” chat, yeah, that detail stays in your head.

The writing leans into the gay tension without pretending it’s healthy. This is not soft-boy BL. The protagonist is in over his head and the demon knows it and enjoys it. There are lines like “You called me here to hurt them, but look at you, already trembling from my fingers. Maybe you were the real offering.” He says stuff like that while dragging his claws over bare skin and you just know it will leave marks later. The game doesn’t jump into instant sex; it teases, presses, corners. The first time the MC wakes up with the demon in his bed, half shifted, tail coiled around his leg, hand low on his stomach, that’s the turning point where it stops being “oops, magic went wrong” and becomes “I belong to something not human and he’s enjoying breaking me in”. The sex when it finally happens is intense and rough, full of that “you asked for this” dirty talk that borders on humiliating. The demon treats the MC like both toy and worshipper, grabs his hair, forces eye contact, uses strength he clearly doesn’t need, drags out his orgasm until he’s crying, then casually reminds him that their pact isn’t finished yet. If you like your yaoi with claws, teeth, possessive monsters and a protagonist who gradually gives in to it all, this hits that exact spot where fear and arousal tangle up so much you can’t see the line anymore.

Guy gets turned into roadkill, wakes up in horny fantasy land, and the first thing the world says is basically “congrats, you’re the protagonist, go ruin everybody’s morals.” That’s the vibe. It looks like some dev took an isekai light novel, poured milk all over it, and then asked “ok but what if every side quest slowly turned nice people into cock-drunk pervs with huge tits.” You wander around clicking on stuff like a regular point and click sandbox, but half the time you’re just peeking at thick milfs bending over, and the other half you’re getting sucked off behind some tavern while a slime monster pretends not to watch. The animated scenes are the real hook: boobs bouncing, milk dripping, asses shaking, all that 3D porn game energy where every character has a spine made of rubber and an ass that would absolutely kill your actual back. One minute you’re in a “normal” fantasy town, next minute you’re sneaking into a bedroom, watching a sleeping woman’s blankets slowly slide off her massive tits, and the game just quietly suggests “hey, what if you corrupt her while she sleeps.” It doesn’t ask if you’re a good person. It assumes you’re not.

What surprised me is how often it tries to be funny and actually lands it, then goes straight into some really fucked up humiliation or slave stuff without warning. There’s this milf with a huge ass who talks to you like you’re a useless little nerd, then three quests later she’s stripped in public, face red, tits out, calling you “master” while pretending she hates it and clearly loving every second. The corruption vibe is slow burn if you click around and talk to people, but if you’re impatient you can just stumble into scenes where a monster gets involved and suddenly that “adventure” tag stops feeling heroic real quick. Oral, vaginal, creampie, sleep sex, voyeur stuff, it’s all there, and the game’s not shy. I had one scene where I was hiding behind a door, watching a thick chick lactate all over herself while she tried to clean up, and I honestly spent more time nudging the camera just to see how the milk rolled down her stomach than progressing the actual quest. Stupid thing that bothered me: sometimes the sandbox pacing feels like the game forgot what it wanted you to do. You’ll be horny, you’ll have your dick in hand, and it’s like “go click this random barrel three times.” But then you get rewarded with some animated stripping scene where a monster girl does this slow, teasing dance that absolutely doesn’t match the silly fantasy tone and somehow that clash makes it hotter. It kinda feels like your browser history got reincarnated with you.

There is this horny little sci-fi sandbox where you basically wake up one day with an alien symbiote stuck to you and it is not subtle at all about what it wants. No tragic backstory, no dead parents, just “hey, we can punch through walls now and also fuck anything that moves, cool?” The tone is kind of funny because the game pretends for ten seconds to be about saving the city from weird monsters, then you’re balls deep in some milf in a broken office with tentacles politely holding the door closed. The symbiote acts like your pervy coach, whispering in your head, pushing you toward more extreme stuff: cheating, public sex, corruption, the works. Sometimes it teases you on purpose, like you walk past a girl doing VR cosplay in her room and the alien is like “we should test her stamina” and you can actually just… stand there and watch her masturbate for a bit while your own hands “accidentally” drift down. I liked that way too much. Or not enough, I’m not sure.

Gameplay jumps around a lot. One minute you’re doing these janky but fun combat sequences, tentacle-lashing alien beasts that try to rip you apart, and the next minute you’re basically running a management sim of your own harem. You roam around, pick which girl to visit, how to corrupt her, how much “symbiote juice” to spend to unlock a new power or new position. The powers are stupid in the best way: super strength for ripping clothes, stretching limbs for reaching… spots, organic restraints that turn into living sex toys. There’s this scene in a neon alley where you fight a monster and then pin it, and the game lets you decide if you drain it normally or let your symbiote “experiment”. I picked experiment, obviously, and suddenly there is a mess of slick tentacles around this alien chick, her big tits bouncing while she’s choking on you and your second mouth is busy lower down. All animated, very explicit, not shy about anal or creampies at all. The movement during oral scenes looks a bit too smooth in a weird way, like those TikTok filters, but I still watched the whole thing, zoomed in, rewound. Twice. And then complained to myself the tongue animation felt off and went back again anyway.

What surprised me is how the romance and corruption are tangled together. You can play the sweet guy with the shy girl at the café, bring her little gifts, flirt, then gradually “share” part of the symbiote with her. It starts like a cute sci-fi romance and ends with her happily letting tentacles hold her ankles apart in a bathroom stall while someone else walks in and pretends not to see. That whole exhibitionism angle creeps in slowly. First it’s playful teasing, a boob slip while using your powers in public, then full-on sex on a rooftop while patrol drones fly by. The game even has multiple endings depending how far you push each girl, but it never makes a big speech about it, the routes just sort of happen as you keep doing what turns you on. I got one ending where my guy basically becomes the city’s secret monster problem solver and also the unofficial porn overlord, running this twisted little harem where everyone is corrupted and happy. I kind of hated that the sandbox flow means you sometimes wander around doing nothing for a while, opening the same menu five times just to trigger the next scene, but when it finally pops and you see that new animated blowjob with the symbiote forming a cock ring or turning her cosplay outfit into living latex, yeah, suddenly that little annoyance at the map icons being slightly off-center doesn’t really matter anymore and I just kept clicking for “research”.

John is one of those guys who lives more in his browser tabs than in his real life. Phone full of gacha trash, folder full of MHA doujins, school life basically on autopilot. The game starts with that vibe so hard it almost hurts, like you can smell his keyboard. Then on a totally normal walk to school, shit goes sideways in a way that feels like one of those fanfics where the author just says "fuck it" and hits the accelerator. There’s an accident, the kind you usually only see in chapter 1 to justify some broken superpower later. John blacks out, meets this weird boy who looks like he walked out of a cursed quirk experiment, and suddenly the whole line between "I’m a loser who watches heroes" and "I might actually be one" gets blurred. Except it’s not about fighting villains. It’s about possessing people and fucking everything that moves in a school that very clearly wants to be U.A. but legally cannot say it too loud. The fun part is how your new power is basically spiritual identity theft. You slip into other bodies, feel their quirks like tight gloves, and then abuse the hell out of them in ways that would get any actual hero thrown in Tartarus for life. First time you possess a girl in class, the camera lingers just enough on her huge tits pressed against the desk that you kinda forget there was supposed to be a "mysterious plot". Then you realize you can walk her straight into a janitor closet, pull her panties aside, and go raw. Creampie inside someone else’s body while still technically being John? It’s fucked up, it’s hot, and the game does not pretend it’s morally deep. It’s just filthy. There’s this one scene where you hijack a monster girl that looks like somebody mashed up Mt. Lady and a slime villain in an AI prompt. You feel her body ripple around a cock in a way that’s clearly not human, like her insides are hugging you on purpose. Anal with her is just ridiculous, the game goes full "physics are optional" and her ass eats the camera. The AI CG helps and also kinda doesn’t, because sometimes a hand has six fingers or the hair melts into the background, but honestly that glitchy energy fits the whole possession theme. Bodies feel borrowed, a bit wrong. You’re not supposed to be there. That actually turned me on more than the polished stuff in other games. Some routes pretend to be romance. You pick softer choices, stay in John’s own body, hang out with a big tittied classmate who clearly has a quirk that is "make the MC horny every time she leans over his desk." There’s a path where you actually try to be decent, worry about consent, walk her home instead of taking the mind-hijack shortcut. And then the next scene lets you jump into her from behind anyway, make her kneel in some dark music room, and swallow you down her throat until she gags. The game has this habit of giving you sweet dialogue and then dunking you right back into filth before it gets too sentimental. It talks about life and death, that early scene with the mysterious boy almost feels like a real afterlife moment, but then you’re back at school, using your "gift" to bend a hot teacher over her desk and fuck her so hard her quirk sparks around the edges of the frame. The multiple endings stuff sneaks up on you too. You think "ok, this is just porn with a possession gimmick", then suddenly a choice you made three scenes ago decides if you end up basically a ghost forever, stuck riding other bodies and never being touched as yourself, or if you manage this weird twisted romance where someone falls in love with John knowing exactly what he is. Some endings are pure corruption, like you go full monster, use your powers nonstop, and the last CG is you blowing a load deep inside a girl while her eyes glow with your presence. Another one is more "heroic", and by heroic I mean you only fuck a handful of people and actually say sorry once. Vaginal, oral, anal, all on the menu. Big asses bouncing on your cock, cum dripping down thighs, messy creampies that keep showing up in later scenes if you messed someone up earlier. The game remembers your sins when it wants to. Then it forgets them if a scene needs you to be "pure" for a romance beat, which is kinda funny. It feels like reading a horny fan comic where the artist keeps changing their mind about tone, but the core is always the same: lonely guy, new power, school full of hot girls, and a world that looks a lot like My Hero Academia if the author fully embraced the fact that everyone already imagines half these heroines getting railed.
