This thing looks like some horny fan’s side project that accidentally turned into a real time sink. You open it expecting some cheap Demon Slayer parody fap-bait and suddenly you’re squinting at the grid going “wait, if I merge this here, it frees that space… shit, I need one more level 4 barrack.” It’s that classic merge, merge, merge style, small stuff into bigger stuff, except the game keeps dangling the lewd carrot in front of your face: build the next tier of building, unlock another dirty peek inside the Demon Slayer Corps HQ. And it really leans into the “secret base” fantasy, like all the serious anime fights happened outside, while inside they’re fucking like rabbits behind closed doors. First few minutes you’re barely paying attention, sliding low-level training sheds around, merging them just to see what pops next, then suddenly you realize you’re trying to min-max some horny base layout because the next unlock says it has Nezuko in it and your brain just goes “yeah ok, I’m not stopping now.”

The art for the scenes is where the game drops the polite act. You get that first tame image, a little teasing, almost like a fanservice shot. Then it ramps. Nezuko pinned half-undressed, bamboo gag nowhere to be seen, thighs spread while some “training session” clearly got out of hand. Kanao has that blank doll face while doing things that would absolutely get her expelled from any real corps. Tanjirou, who looks so earnest in the anime, here is the guy fucking someone on top of a mission table while papers are flying around, and I swear there’s a map under his ass. You unlock one with Shinobu and it’s this perfect “soft smile, filthy mouth” combo, her legs casually open like it’s just another experiment, only now she’s testing how much cum she can take on her stomach. Half the fun is waiting to see who gets corrupted next and how far the artist will push them. The game doesn’t pretend it’s about romance or “deep bonds” either. It goes straight into rough training, handsy “medical exams”, tits squeezed under haori, panties pulled to the side in some corridor taken like it’s nothing. A lot of fan art out there is shy about actually showing penetration. This one? Nah. Full dick, wet folds, messy faces, cum strings, all that good nasty stuff. Even the backgrounds are specific enough to feel like real HQ rooms: barracks with futons tossed everywhere, storage closets with crates stacked while someone’s getting railed, a strategy room where nobody’s strategizing anything except how to fuck on the main chair.

The puzzle side is where it weirdly gets addictive. You’re not dragged through a story, it’s just that merge logic loop. Combine two low-level structures into one better building, clear space, plan your next merge, avoid clogging the board with useless low-tier crap. It’s simple, but your brain starts doing that quiet math: “Ok, if I wait for one more basic hut, I can merge three chains and hit the next unlock.” I had that one moment where I was one building short of the next scene with Kanao and I just stared at the board like an idiot, trying to find some sneaky chain I missed. And of course I hadn’t. Had to grind a bit more. That kinda annoyed me, but I kept going anyway, which pisses me off more because it means the dev knew exactly what they were doing. On the flip side, sometimes the board feels cramped and you’re fighting clutter rather than enjoying the lewd chase. There were moments where I was muttering “ok, but let me fuckin see Shinobu already” while moving another pair of ugly small huts out of the way. The pacing of unlocks is mostly nice, but once or twice it stretches that gap just a bit too long, and you notice you’re not touching your dick, you’re just playing a puzzle game about horny ghost buildings. I kind of wanted one extra little mechanic, like a risk/reward button that lets you sacrifice a half-built chain to instantly reveal a blurred teaser. Or some special HQ upgrade that gives you an alternate sex scene version of the same girl, like “normal training” vs “punishment round” or maybe a drunk late-night scene where Nezuko is sitting in Tanjirou’s lap, kimono slipping off her shoulders, his hand under the fabric while she bites his neck instead of the bamboo. The funny part is I’m pretty sure if they added more stuff I’d still complain that the merge grid is too small, even if it’s totally fine. That one stupid tiny building that never lines up where you want it? I hate it. I still merged it, though. And yeah, the morning after I mostly remembered one scene of Shinobu kneeling in front of a low table in HQ, haori sliding down, lips open, cum dripping on the tatami, while the game gently popped up a tiny “new building ready” icon in the corner like it’s just business as usual.

Inosuke gets dropped in this quiet little town that clearly wants to fuck his brains out more than it wants to be saved, and somehow that actually works. You start thinking it’s just a silly parody thing with him running around half naked, yelling at everyone, but after a bit you realise the place itself is kind of like a huge horny puzzle box. Every house feels like it hides something dirty and something serious at same time. You go from talking to Nichika with her weird, polite vibe to suddenly getting cornered by Daki, and the switch between “mystery” and “I’m about to ride your dick” is stupid fast in the best way. It’s a sandbox style, so you’re mostly just walking around, poking into places you probably shouldn’t, triggering scenes with people that absolutely look like they have better things to do than fuck this wild boar boy, but nope. They really don’t.

The art hits that 2D parody sweet spot where you know exactly who everyone is, but they’re dialed up just enough to be filth. Mitsuri’s chest is straight up weapon grade. Nezuko’s mix of cute and needy is kind of unfair. Aoi pretends she hates you, then melts the second the clothes come off. My favorite was Shinobu and Kanae, actually. The mood changes so much with them. One moment Shinobu is all sweet smile and small talk, next you’re balls deep, her eyes glazed, full ahegao, knees shaking like crazy. And it’s not just a CG collection you click through. Scenes tie to where you went, what time of day, who you annoyed before. One time I wasted ages chasing Tamayo around town, trying to unlock her event, just to find out I had to talk to some random Ubuyashiki girl first. I swore at my screen, but when the payoff came and Tamayo slowly undressed, climbed in my lap and whispered like I was some chosen pervert, yeah, I shut up fast. The game makes you feel like an idiot, then a sex god, then an idiot again, and somehow it fits Inosuke perfectly.

What I really liked is how the town pretends it has this huge dark legend going on. Clouds gather, people shut up mid sentence, everyone keeps saying “You shouldn’t be here” while at the same time grinding on you five minutes later. It’s ridiculous. There’s this whole build up where you think you’re finally going to uncover the main secret, and instead you get Uzui’s wives dragging you into a chaotic group scene that just explodes into moans and limbs everywhere. Part of me wanted a deeper story finish, but honestly, when Makio is riding you hard, Suma is sobbing with pleasure on your tongue, and Hinatsuru is whispering filthy shit in your ear, you kind of forget you ever cared about plot. Still, one small thing annoyed me: sometimes you’re just wandering around, no clue who to talk to next, and the game gives you zero hint, like it’s laughing at you. I sat in front of the same inn door, pacing between rooms, checking my phone, opening Reddit once, and nothing. Then suddenly, triggering Nakime in this tiny side area starts a chain of events that lands you in bed with Mukago and then Mitsuri, like knocking over horny dominoes. It’s messy, unbalanced, a bit rude with your time, and very, very on-brand for a Demon Slayer parody that turns “save the town” into “fuck everyone until the secret doesn’t even matter anymore.”

Okay so like, this game takes the whole Demon Slayer thing and just... goes completely off the rails with it? You get turned into a demon and somehow end up in the past where everyone looks exactly like the anime characters but they're all horny as hell. It's like someone watched Kimetsu no Yaiba and thought "you know what this needs? More tits and fucking."

The combat system is actually pretty decent though - turn-based stuff that doesn't feel too grindy. You can choose to be good or evil which is cool I guess, but let's be honest, everyone's gonna pick the evil route to see Nezuko get railed. Speaking of which, they got basically every female character from the series here - Mitsuri with her massive knockers bouncing around, Shinobu being all tsundere before you corrupt her, even some of the background characters like those butterfly mansion girls. Wait actually I think there's futa content too? Not really my thing but hey, options are options. The sandbox elements let you kinda do whatever but sometimes the pacing feels weird, like you're just grinding relationship points until someone drops their panties.

What really got me though is how they handled some of the characters - like Tamayo is supposed to be this dignified demon doctor lady but here she's basically a horny milf who wants demon dick 24/7. And don't get me started on the Ubuyashiki family stuff, that's some questionable territory right there. The animations are pretty smooth when they work, but sometimes the scenes just... stop? Like mid-thrust and you're left staring at a frozen screen. Also why is Zenitsu even in this game, dude's annoying as fuck in the anime and somehow even more annoying here. The furry tag threw me off too - turns out there's some beast demon content that's honestly kinda hot if you're into that sorta thing. Overall it's messy as hell but scratches that parody itch real good.

First thing, this thing feels like someone took Demon Slayer, ripped out the wholesome shonen soul, then glued in a horny brain that only thinks about boobs, thighs, and “how far can I push this before my phone overheats.” It plays like an old school visual novel on android, with that dating sim vibe where you click through dialogue, make choices, and try not to fuck up the route. Except here, “fuck up the route” usually just means you didn’t see Nezuko’s panties or you got friendzoned by Kanao while she’s literally blushing in lingerie and talking about how “this is only for training.” Sure, training. Totally. The story pretends to be about love, but it’s basically you, a demon slayer self-insert, circling around the girls like “haha I respect you as a warrior” while the game quietly hands you options that say things like “touch her thigh anyway.”

What I liked is how stupidly on point the personalities are, just twisted into horny mode. Kanao starts off quiet and polite, then one wrong choice and she closes off harder than your internet when mom pulls the router. But if you keep picking the kind answers, suddenly she’s in your room at night, still in that butterfly outfit, asking if kisses count as “practice in focusing.” Shinobu is the real problem though. She smiles at you while saying shit that sounds sweet but is actually dirty as hell if you read between the lines. One scene she lets you “check her injuries,” and somehow it turns into you lifting her top inch by inch, the text getting more detailed about her skin, her breath, her fingers on your wrist, like the writer was getting horny mid sentence and forgot subtlety. And yeah, Mitsuri is here too, of course she is, the game treats her boobs like they are separate characters with their own route. There is a bath scene with her that honestly felt like the dev just paused an anime screenshot, stared at it for too long, and said “yeah, I can write something from this.” Spoiler: they did, and it’s filthy in a good way.

Then there is Daki. She is not even pretending to be romantic. Her sex scenes feel like a challenge run. You get punished, teased, stepped on verbally and sometimes literally, and if you pick the more “pure” choices she basically laughs in your face. Tamayo is the opposite, very soft, caring, “let me heal you” energy, but the game lowkey pushes her into this mommy role that gets quite explicit once you let her “reward your bravery.” Nezuko’s route is a bit sus at first because she is all shy and cute, but the moment she starts talking more, it escalates fast. The simulation parts are light, like you choose where to visit, who to talk to in the mansion or in the city, and certain times of day unlock lewder scenes. I had this moment where I accidentally triggered two routes overlapping, so I went from a flirty tea scene with Shinobu to a jealous Mitsuri asking why I smell like her perfume. The game does not properly explain how the flags work, which is annoying as hell, but also kind of fun because you stumble into scenes you did not expect, suddenly you are sandwiched on a futon with a Hashira on each side and no idea which line of dialogue got you there. It’s messy, horny, a bit broken, and exactly the type of scuffed porn VN that lives on your phone between TikTok and Chrome like a dirty little secret.

This one feels like somebody took a giant porn folder full of every anime crush you ever had, fed it to a very horny robot, and then just let it loose in the middle of the night. It is messy, shameless fanservice in the best and worst way. You start as this generic male MC that nobody cares about, but it honestly works, because the spotlight is always on the girls. One minute you are staring at Android 18 pretending she is not seconds away from sitting on your face, next moment Tsunade is bending forward like your spine insurance is fully paid, and after that DVa is giving you this smug gamer grin you only see from sweaty tanks in Overwatch comp. Nothing really tries to be “deep”. It is like those late-night Discord calls where everybody starts posting cursed Koikatsu cards and then suddenly somebody says “wait, I can make a whole game with this” and nobody stops him. The whole thing runs on that energy.

The date sim part is kind of funny, because yeah, technically you are “dating”. You choose outfits, say the right lines, sometimes click through fake romantic setup, but everybody knows you are just trying to figure out how many scenes Mirko has and whether Rias or Nami has the better titfuck animation. And the girls are not just random OC clones either, they actually feel like somebody who watched too much anime made them on purpose. Aqua is clingy, loud, kind of dumb but insanely cute when she starts grinding on your lap like she is trying to win some idiot contest. Yoruichi keeps that smug cat energy, sits on your face like that is the most normal place in the world. Toga looks at you like a snack she is not supposed to have, then happily chokes on your cock like rules stopped existing. And then there is stuff like Vados or Kefla or Caulifla, where your brain is trying to remember power levels while your dick is just happy there is yet another big ass bouncing in your face. They even throw in weird combinations, like giving Bowsette this slow, teasing blowjob scene that lasts just long enough to make you forget you were actually trying to see the Zelda content first. By the way, whoever decided Misty and Jessie need extra focus on footjobs has some stories to explain to a therapist someday. I still appreciated it.

I really like how the pacing somehow feels both rushed and too slow. First girl I tried was Ai Hoshino, because of course I did, and the “date” was over in like two clicks and suddenly she was kneeling between my legs, lipstick smeared on my cock while she looked up with those idol eyes. Then with Hinata I had to go through this longer flirting phase, a bit of voyeur setup, peek under her clothes, touch her softly first. It felt like waiting for food that keeps smelling better while you are starving. Annoying, but in a good way. Or bad. Not sure. Anyway, everything is pure fetish salad. Oral sex scenes everywhere, big tits bouncing like they are competing with each other, asses in your face so often it starts to feel like some kind of religion. I got stuck way too long just watching a Raven scene where she rides you slow, still in half her Teen Titans vibe, moaning soft while her ass cheeks clap in that hypnotic rhythm. Meanwhile I completely forgot I had not even checked Mirko, Mina, or Nejire yet, and those are usually my first picks in any MHA fan game. Still, the weird part is how sometimes the small stuff hits the hardest. Like a moment where Komi is trying to suck you off, all shy and stiff, and the camera lingers a bit too long on the way her lips tremble around the tip. Or the way Marin Kitagawa giggles after swallowing, wipes her mouth with the back of her hand, then casually asks for “another round” like you just finished playing some gacha together on your phone. At one point my Chrome lagged for a second right when Tatsumaki started a titfuck and I legit got angry, like, that tiny freezing framed her smug face perfectly and I will never see that exact glitch again. Yeah, the game is scuffed, uneven, totally horny, and absolutely not refined. I keep alt tabbing to Telegram and back just to check something, then losing track of which girl I was “romancing” and honestly that chaotic feeling kind of fits.
