Your quiet little life with mom and your cute, clingy sister shatters in one night. Blood on the floor, broken door, mom dragged off by demons like she was nothing, and your sister… yeah. She doesn’t just turn into a demon. She turns into the kind of demon that makes your brain short circuit and your pants painfully tight at the same time. Her eyes glow, her body changes, she presses close and you’re supposed to think only about saving your family, but all you can think about is how wrong it feels that it actually turns you on. This game leans into that. It doesn’t pretend you’re a saint. It laughs in your face and pushes all those incest, corruption and demon fuck fantasies you keep pretending you don’t have.

From there it’s you, a wooden sword, and a pile of horny problems. You train, you flirt, you get beaten up by demons that either want to kill you or ride you or both. The story follows your climb from useless guy who can barely swing a blade to someone who can slice up monsters and still have enough stamina to pin a horny demon girl to the ground. Sometimes literally. You run into familiar faces, twisted in fun ways: the loud blond idiot who can’t stop shaking around girls yet still somehow steals scenes, the boar mask maniac who looks like he wants to fight you and fuck you at the same time, the insect-smiling beauty who talks soft while planning how to milk your body for “research.” And then there is the “doctor” type with that calm, mature vibe that makes you feel safe right before she asks you to undress for a “test.” The game likes to take every girl you know from the anime and nudge her into “what if she was horny and absolutely not safe for work” territory.

Sex here is not just a reward screen. It sneaks in during training, after fights, in weird dream sequences where your demon sister crawls over you whispering things she definitely shouldn’t know. You’ll get seduced as much as you do the seducing. One moment you’re practicing breathing techniques, next moment some busty demon pushes you against a tree and uses your “sword” as her own training tool. There are choices, but the game is pretty honest: no matter what you pick, you’re still stuck in this messy mix of lust, guilt and blood. Sometimes you try to be noble and help a girl, then end up with her moaning under you on a futon while you both pretend this is “just stress relief.” Other times you clearly aim for corruption and the game rewards you with scenes that feel like you shouldn’t be watching them in public, even on a phone. It’s not subtle, not classy, not pretending to be anything else. It throws demons, tits, knives, and moral decay into one pot and says “yeah, this is your life now.” And honestly, it kind of works too well.

This one feels like somebody took a regular isekai fantasy story, spilled porn all over it, then just went “yeah, that’s fine” and pushed it out the door. You start as this guy who somehow plays with both light and darkness, like he’s half holy hero and half horny demon, and everything around him is completely fucked. Worlds broken, reality torn, big cosmic mess that nobody is really fixing because everyone is too busy being hot and dramatic. Then, out of nowhere, his own sisters show up as his “unexpected allies” and it goes from epic adventure to “ok, should I actually be turned on by this or should I go confess something” in about two scenes. The game leans hard into this taboo vibe, like the universe is collapsing but you’re still stealing kisses and grabbing thighs in ruined temples while angels are screaming in the sky. It’s not subtle. One moment you’re arguing about destiny and fate, next moment you have someone pressed against a wall, panties around one ankle, while she whispers that she’s not supposed to want this. I was on Chrome on my laptop, had Telegram open on the side, and honestly kept forgetting to reply to people because the story kept throwing new crazy shit at me.

The thing that really stuck with me is how it jumps between romance and total depravity without warning. You’ll have this quiet scene with one sister sitting at a campfire, her hair all messy, talking about how she’s scared of being erased with the rest of the worlds. It’s sweet, kind of sad, you almost feel like you’re in some emotional anime. You choose the “nice” dialogue, she smiles, looks relieved, leans her head on your shoulder... and in the next click she’s on her knees, eyes glossy, calling you “big brother” with this broken little moan that hits you straight in the brain. I actually paused for a second and just stared at my screen like, the fuck did I just agree to. And then there is Lucifer, who should be this scary demon boss, but half of the time feels more like a smug dom roommate who shows up, beats your ass in a fight, pins your MC to the ground and basically goes “you’re not ready to save anything yet, but I might let you touch me if you beg nicer.” The Inquisition girls are no better. They act like they want to burn you for heresy and then end up half naked in some torture chamber asking you to “punish” them for betraying their faith. I wish the choices actually changed more stuff, but at the same time I don’t, because I kinda like getting dragged along this unhinged ride and just seeing how wrong it can get. The animations hit that messy hentai energy where sometimes a leg bends weird or the boobs move like they have their own gravity, but weirdly that makes it feel more raw, not less. I stopped noticing after the third corrupted nun begged me to fill her while the sky was literally cracking open above us and light and darkness were swirling around like some horny apocalypse. I honestly opened it just to kill a few minutes between YouTube and Twitter, and now I’m stuck thinking about a fake sister with tears in her eyes, saying she’d rather let the worlds die than give you up. I hate it. I want more.

Conrad starts as this kinda average guy who just wants to sell clothes and maybe touch some tits in peace, and the game immediately laughs at that idea. It throws him into this weird mix of family drama, horny tension and lowkey spooky shit hiding behind cute outfits. You play from his head, and it is a mess in there in a good way. One moment he is talking about fabrics and color palettes for the new store logo, next moment he is staring at his sister’s ass while she leans over the counter and he tries to pretend he cares about invoices. The game really leans on that “I should not want this, but I really, really do” incest vibe. She walks around the house in tiny tops, there is this one scene where she asks him to help measure her waist for some new stock and the tape just “accidentally” slides under her boobs. As a SFX addict, I went straight to listen for the tiny details and the way they put this little fabric rustle when her shirt lifts and that soft wet swallow when he tries to calm himself, that stuff is way more erotic than half of the moans later.

The possession angle is what makes it feel less like just another “hey sis, suck me” mobile thing. Conrad starts having this presence in his head that does not always talk, but it kind of pushes him. There is a moment in the shop basement, he is alone with his sister, arguing about a late delivery, and suddenly you get this choice to “relax” your control. You click it, the screen tint goes darker, and his hand just moves on its own and grabs her hip, fingers digging into her skin. She gasps, you hear that sharp inhale in your headphones, the little shaky breath after, and she doesn’t pull away right away. That pause is filthy. The possession makes all those groping scenes feel half innocent, half “I totally meant that”. Sometimes he resists and you get a sweet handjob scene where she is the one comforting him because he is “stressed”, sometimes you let the demon inside or whatever control him and suddenly that same scene goes way rougher, more like he pins her wrist and forces her to keep stroking. The wet sound design there is honestly illegal, I had to turn my phone volume down on the subway since it sounded like I had Pornhub autoplay in my pocket.

It is also kinda funny how the game pretends to be about a clothing store and fantasy destiny and all that, but the most intense moments are in small places. Him under the sewing table while she is on a phone call, her bare feet brushing his thigh, and that option to let the “force” slip into her instead. When that happens, her voice changes just a bit, like this softer, breathier tone, and she starts talking nastier without even noticing, twisting her words about “stock” and “orders” so it sounds like she is talking about cocks and orgasms. If you push it, you can jump full into possession and ride her body like a stolen car, taking control while Conrad watches from the back of his own skull. That leads to some really fucked up blowjob scenes where her eyes are empty but her mouth works like a pro, and the slurping audio is honestly disgusting and hot at the same time. I give this thing my very serious “Best Use of Demons To Justify Wanting To Fuck Your Sister” award. It is rough around the edges, some lines feel like Google Translate had a hangover, but maybe that is why it stuck with me. The world is kind of soft fantasy, but what really lives in my brain is that quiet moment when she whispers “big brother” and you can’t tell if it is really her or the thing inside. I wish there was less UI clicking for simple actions, but whatever, my thumb survived.

Nami getting lost on some random island feels exactly like something that would happen in One Piece, but this game takes that idea and just strips all the shounen “friendship and adventure” crap away and leaves you with one thing: horny, selfish survival. You’re not here to be a hero, you’re here to watch a cute redhead pirate slowly sell out every bit of her pride just to escape a place that basically wants to eat her alive, piece by piece, in the dirtiest way possible. It starts almost innocent, like a goofy little parody where she’s annoyed at being separated from the crew, muttering about Luffy being useless again, and then the island starts pushing back. Weird altars, shady “deals,” strange creatures that feel like someone mashed hentai tropes into a blender and forgot to put on the lid. Suddenly it’s not about map charts anymore, it’s about how far she’s willing to go, how much shame she can swallow, and how much you want to see her fail at resisting.

The visual novel style actually works way too well here. You just click through and think “ok, it’s just text, it’s harmless,” and next thing you know you’re carefully choosing dialogue that pressures her into just one more little compromise. Say something rude to a pervy spirit, lose some safety. Say something flirty to get what you want, lose some dignity. It’s not super complex but it doesn’t need to be, because the corruption is the main toy. There’s this moment early on where she has the chance to walk away from a suspicious shrine and every normal player brain screams “this is a trap” and somehow your finger still goes to the option that makes her kneel and check it more closely. Same energy as pretending you’re going to play “for the plot” and then the first CG hits and you’re quietly turning the screen brightness down and closing Discord like you’re hiding a crime. The art leans hard into that anime parody look, you can tell exactly what character this is based on, yet her expressions are way dirtier than anything Oda would ever draw. Sometimes her face looks a little off and proportion goes weird for one frame, but honestly, it kind of fits the whole cursed island mood, like the world itself is a bit warped and sleazy. The sex scenes escalate from “oops, this is embarrassing” to “okay this girl is ruined and pretending she’s fine” and by that time your choices already pushed her there, so congrats, captain, this is your fault.
