First thought when this thing loaded was basically “ok, this looks kinda jank… but I’m curious” and yeah, that sums it up. It feels like somebody really horny and slightly drunk decided to mash Demon Slayer waifus and a dating sim in one weekend, and somehow it works better than it should. You’re not grinding demons here, you’re grinding affection bars and lewd scenes, talking your way into the pants of Shinobu, Nezuko, Kanao, Mitsuri, Daki, Tamayo and a few others the dev clearly has bookmarked in his Rule34 folder. It plays like a visual novel with some light sim stuff stapled on: you click through scenes, make choices, pick where to spend time, watch numbers go up, unlock another scene where a “pure” girl suddenly rides you like she’s been training for it. Totally classy. Totally not classy at all.

What surprised me is how each girl has her own vibe, even though the game is pretty scuffed. Shinobu goes from teasing “ara ara, you’re kinda cute” into straight-up talking about how she wants to milk you until you can’t stand. Nezuko’s route leans into that quiet, needy thing: lots of blushing, sucking, licking, her climbing in your lap like a cat in heat. Kanao starts super shy, barely talking, and then there is this moment where you finally break through her coin-flip bullshit and she decides, with this tiny smile, that she’s going to “devote herself” to you. Two scenes later she’s on her knees, eyes glassy, letting you cum on her face, and the script doesn’t even pretend it’s about romance anymore. Mitsuri is just horny from the start and I respect that. She goes from “I really like strong men” to “please fuck me until I can’t walk” in like three dialog boxes. Daki is straight-up toxic, which is hot: she insults you, treats you like trash, then moans when you pull her hair and pound her so hard her demon composure breaks. Tamayo is the gentle one, but of course she ends up on a table, skirt pushed up, letting you take out “stress” on her while she tries to stay composed and fails. The whole thing swings from romantic to filthy in seconds, and it feels wrong in a fun way.

The actual game part is simple as hell. You pick spots, talk, give gifts, answer horny or sweet, watch affection rise, unlock another scene where clothes magically vanish. There’s no deep stat management, just enough clicks so it doesn’t feel like a pure gallery. Sometimes the pacing is weird: a long dialogue about feelings, then the next choice is basically “do you want to fuck her now or fuck her harder later” and of course you pick both. I liked one moment with Shinobu where you end up in a quiet room in the butterfly mansion, she’s fake-innocent, leaning closer with that smug smile, then the text hits you with her whispering what she wants you to do to her tongue, and suddenly this hentai Android game in my browser feels way dirtier than it looks. Another time with Nezuko, the CG opens and she’s bent over, drool on the floor, and the game just casually describes how she pushes her hips back, begging without words. Honestly I wish some scenes were longer, but also I don’t, because the short, punchy lewd moments keep you clicking for “just one more” like a degenerate. It’s rough, unpolished, sometimes cheesy, but when Mitsuri is bouncing on your cock, tears in her eyes, babbling about how she loves you and your “thick human cock”, you kinda forget it ever looked scuffed at all.

Inosuke getting dropped into this “mysterious town” feels like someone took Demon Slayer, put it through Pornhub search history, and decided, yeah, let’s make that a life. You walk around this quiet place where everyone is pretending nothing is wrong, but the vibe is so horny it’s basically fog. People talk about “strange events” and “legends” but half the time you’re just thinking, ok, which busty demon or milf doctor or smug slayer girl is going to drag his dick into trouble next. It’s a sandbox, so you’re not pushed in a straight tunnel. You wander, poke your nose where you shouldn’t, trigger scenes by accident, and suddenly you’re watching some demon girl with huge tits riding Inosuke so hard her eyes go full ahegao and the text box is just moans and “more” spam. What really hits is how casual the lewd is. You can be walking past some house, talking about “shared secrets”, then boom, fade, and now your boar-headed idiot is balls-deep in someone that would get most gacha games banned from the app store in five minutes.

The fun part is how the game treats all those familiar girls from the series. Mitsuri is exactly as dangerous and sweet as you expect, except the camera cannot stay away from her huge ass for more than two seconds. Shinobu looks calm and teasing and then talks to Inosuke like he’s a toy to experiment on, clinically, while she’s jerking him off on a bed she definitely uses for “medical research”. Nezuko showing up is this mix of “oh shit fan favorite” and “ok yeah this is absolutely fanart that escaped from Pixiv and learned to walk”. Then you have Tamayo being all elegant and soft, inviting, with that slow, almost motherly rhythm when she rides him in one scene that honestly felt more intimate than anything, until the dialogue reminds you she’s still hiding something huge from him and you’re basically fucking on top of lies. I use Auto Clicker on my phone to skip grind in a lot of games and I swear, here I kept pausing it just to read how they wrote the dirty talk, even when the English gets a bit weird and clunky. It actually matches my own dumb level of grammar in a good way, like talking dirty in your second language and not caring if verbs are correct as long as the dick is.

There is this one alley encounter with Daki that kind of sold the whole town for me. She acts annoyed, like he is a bug, and you think, ok, she’ll torment him, maybe humiliate him, but the scene flips into this nasty, aggressive vaginal pounding where she’s the one losing control, clawing his back and ranting about his stupid body while she trembles. Her face goes full broken ahegao, tongue out, and the game just leaves it hanging with no big plot payoff, just a memory you can replay later. Honestly, the biggest problem for me is how the sandbox sometimes feels like you’re circling the same spots waiting for the next sex flag to trigger, and there isn’t much actual “RPG” beyond moving, talking and getting new scenes. You keep hearing about legends and secrets like some big mystery, but when the option appears to just ignore it and keep fucking everyone in town, the game laughs and kind of pushes you in that direction anyway, like “yeah, detective work is cool, but have you considered raw demon pussy”. I got stuck once because one character only shows at a weird time of day and I kept missing her, and it pissed me off more than any boss in a normal game, but I never looked up a guide. I just wandered, talked, and ended up in a random room where Hinatsuru was on all fours, and Inosuke behind her, using her ass like he was trying to kill a demon with his cock. At that point the whole “mysterious town” plot is just background noise for one simple thing: every corner hides another excuse to watch this idiot protagonist fuck his way through the cast like the series was always meant to go that direction and the anime just chickened out.

Can’t lie, I clicked expecting another copy-paste anime mashup with the usual stiff models and dead-eyed moans, but this one hits different. There’s a sadness under all that skin, like someone coded their fantasies too carefully, you know? I found myself staring at Raven’s face - Batman’s Raven - and thinking, “she shouldn’t be looking at me like that,” while still dragging her into position anyway. Unreal how fast guilt turns into hunger when the animation breathes just right. And maybe it’s because of the Illusion engine doing its sneaky physics thing, or maybe because the transitions are almost clumsy, like real people fumbling with clothes and patience. It’s messy, which makes it hot.

The scenes jump from universes without pretending to make sense. One second I’m in some broken-down Capsule Corp lab, Bulma smirking like she *planned* to get caught; next, Yoruichi’s toes press against my chest, laughing, telling me to look up. I did. Of course I did. The voyeur mode feels wrong in the best possible way - it doesn’t even give you fake morality options, just lets you watch. But then again, maybe that’s lazy design. Or genius. Hard to tell when your brain’s half-melted. The weird part? The sound mix changes depending on position, so D.Va sounds distant if she turns away. I swear no one ever gets audio that intimate, not even those overpriced VR patches on Steam.

Anyway, I could say it’s perfect, but I won’t. Some things twitch too mechanically - the faces sometimes freeze mid-expression, like they remember they’re code. Yet that’s also the charm. You see the seams, and you keep touching them. Like rubbing a wound for pleasure. Half the cast shouldn’t exist in the same space - Orihime beside Tifa beside Samus - but here they crowd my screen like they’ve been waiting forever. Maybe that’s why it works: it’s absurd, obscene, familiar, and somehow lonelier than expected. I closed the browser and immediately reopened it. Couldn’t help it.

Isekai Brothel feels like someone cracked open my anime watchlist, dumped it on the bed, and said, “Ok, pick who you wanna fuck first.” It’s a dating sim wrapped around a brothel idea, but not the usual boring “pick one route, marry waifu, roll credits”. Here you jump between worlds and timelines, grab girls from different series, and basically run this horny multiverse where fidelity is a suggestion, not a rule. As a poly person this hits weirdly close to my fantasy: not needing to “pick best girl”, just stacking them like a chaotic harem Jenga tower and seeing what breaks first, your dick or your free time. And yeah, it’s messy. The art style and scenes don’t always match perfectly between girls, the transitions sometimes feel like someone hit the skip button too fast, but honestly that fits the vibe. It feels like a porn stash, not a museum.

What I liked a lot is how it leans hard into the “brothel” part without pretending to be moral about it. You flirt, you pay, you fuck. Sometimes you date first, sometimes you go straight to raw dog in a rented room. One moment I was having a kinda sweet “date” with a shy girl, choosing dialog options that made her open up, and then suddenly I was balls-deep while she begged me not to pull out. The jump from wholesome to filthy is fast and I actually enjoy that whiplash. There are quick sex scenes for when you just want a 2-minute stress relief, and longer dates where you build some tension before ruining her makeup. The game throws in fetishes pretty casually, like, “Oh, you clicked this girl again? Guess we’re doing anal now” and doesn’t over-explain anything. It trusts that if you’re on an adult site and recognize half these characters, you already know what you’re here for. One tiny thing that annoyed me: sometimes dialog sounds like it was translated twice through Google, then drunk-edited, but honestly I still liked that more than fake polished porn writing that nobody talks like.

The multiverse teleport tech is a cool excuse for why everyone is in one place, but the real fun is when you start mentally mixing “lore” from different shows while you’re mid-thrust. I was fucking a certain very proud, very stacked demon girl while thinking “if her boss from that other universe walked in right now, he’d probably applaud.” Then I switched to a sweet healer-type girl and went from rough choking and hair pulling to soft missionary and kissing like some kind of emotional whiplash speedrun. The game doesn’t punish you for jumping from girl to girl; it almost encourages it, like “you liked that dommy mommy? Nice, go cuddle the awkward schoolgirl now, coward.” It’s not trying to be classy, and I appreciate that a lot. Sex here can be romantic, sure, but it can also be just sloppy blowjob in a side room while other clients are busy in the back. I kinda wish there were more scenes where the girls interact with each other and not only with you, like full-on group sessions that acknowledge relationships between them, but at the same time I like the feeling that I’m sneaking from room to room, collecting different bodies and personalities like a horny little goblin. The whole thing feels like a guilty browser tab you forget to close, which is exactly how this kind of game should feel.
