First time I booted this thing up, my laptop fan went absolutely nuts, like it knew what kind of filth I was about to witness. I laughed so hard I almost spilled my instant ramen, which would’ve been tragic because I was starving and broke back then. Anyway, this Ren’Py thing - honestly, I didn’t expect much. I thought it’d crash after the opening screen, but then Mitsuri showed up with that ridiculous pink-green hair and that voice that’s half sugar, half “I could ruin your life.” I swear I forgot this was fan-made for a sec. There’s this weird comfort in seeing familiar faces from Demon Slayer in a totally different vibe - like seeing your high school crush at a bar years later, drunk and suddenly way too friendly.

The writing’s uneven, but that’s kinda the charm. One moment you’re reading this sweet, shy dialogue with Aoi, and the next, she’s saying something that makes you check if your door is locked. I remember playing on my old ThinkPad, lights off, window open, the neighbor’s dog barking while Shinobu’s scene started - real mood killer, but I didn’t stop. The transitions are clunky sometimes; like, the story jumps without warning, but then, who cares when Nezuko’s sitting there giving you that look. The guy who coded the affection system probably gave up halfway through, but somehow it works better that way. It’s messy, human.

What I didn’t expect was how nostalgic it made me feel. Not just for the anime, but for those early days when I’d sit up late clicking through janky visual novels on Itch.io, hoping my antivirus wouldn’t freak out. It’s pervy, sure, but also weirdly sincere - like it’s not pretending to be anything more than horny fan service stitched together by someone who actually liked these characters once. I got annoyed at the save menu though, it freezes if you click too fast. Never fixed that. I guess I could’ve looked for a patch, but nah. There’s something honest about a game that stays broken in the same spot every time you play.

It’s weird how a game can make you forget what you were actually doing before you clicked it, right? I opened Isekai Brothel thinking it’d be another lazy copy of those generic dating things where everyone stares blankly while you mash through dialogue, but this one… it plays dirtier. Not just in the obvious way (though yeah, there’s plenty of skin and moaning and all that), but in how it messes with your head. You start bouncing between universes like some horny multiverse courier, and suddenly you’re arguing with a half-demon waitress about who’s topping tonight. Then the game throws a slime girl at you, and she calls you “master” like she means it, and I swear I almost dropped my mouse.

The writing is all over the place - half of it’s like someone’s fanfic got drunk and made out with another fanfic, and I kinda love it for that. One scene you’re flirting with a cold swordswoman who barely talks, next thing you’re being pinned by a dragon maid who insists she’s just “checking your health.” Some of the transitions are a mess; one minute it’s sweet, then bam, full-on rough roleplay with no warning. I tried to complain about the pacing, but then a certain pink-haired girl whispered something about “rewarding loyal patrons,” and honestly, whatever I was mad about just evaporated. The voice bits - when they’re there - sound like someone recorded them in a closet, but that weirdly fits the vibe. Like, you’re not supposed to take it too seriously.

There’s a little bug where the bed scene music overlaps with the dialogue if you skip too fast. It drove me nuts, but also, I didn’t stop clicking. Something about collecting girls from different worlds, each with their own twisted little quirks, scratches an itch I didn’t know I had. Half of them act like they hate you, the other half worship you like a god, and both make sense somehow. It’s not classy, not polished, not even pretending to be - but when the screen shakes and she says your name like that, who even cares.

Rosenwick chews you up and spits you out, then the game hands you a second life and basically says, “Ok, now corrupt everything.” You start as this street rat who somehow crawls his way into a super fancy academy, the kind of place where everyone smiles but half of them are hiding knives behind their backs. The story actually takes its time here. You’ve got your childhood friend who feels way too pure for this messed up world, you’ve got rich brats who think you’re trash, teachers with that “I’ll ruin you but make you enjoy it” vibe, and gods watching the whole thing like it’s their personal drama show. When the betrayal hits and you end up thrown away like garbage, that’s when it gets fun. A goddess shows up, gentle voice, soft boobs, sharp eyes, and she offers you a new world. And, yeah, she’s not doing that out of kindness.

The new world is where the horny brain starts screaming. Fantasy setting, but not the usual boring “hero saves kingdom” stuff. You’re handed this power that lets you slowly flip the balance with almost everyone around you. Girls who looked down on you before suddenly have to kneel. Highborn ladies, strict teachers, cute beastgirls with fluffy ears, mature women who pretend to be composed but melt the second you get rough with them. The voyeur bits are some of the best parts; you’ll catch a girl secretly touching herself thinking about you, or spying on two classmates going at it in the dorm bath, and the game actually reacts to whether you just watch, interrupt, or humiliate. H-scenes are pretty varied: slow kissing and handholding for the romantic stuff with that childhood friend who clearly worships you, then choking, hair-pulling, face-fucking others while you creampie them again and again like you’re trying to rewrite them from the inside. There’s a titfuck scene early on that should not be as good as it is, considering it uses AI-style CG, but the animation sells the sloppy, messy feeling so well I had to pause for a second and just stare. Then I noticed one of the nipples looked a bit cursed and I couldn’t unsee it, but whatever, still hot.

What I like is how scenes sometimes start as cute and then just go off the rails. A quiet study session in the library turns into the teacher kneeling under the desk, swallowing your cock, trying not to moan while students walk past. A “friendly” sparring match outside the academy becomes you pinning a muscular catgirl to the ground, fucking her so hard in missionary that her tail curls and her ears twitch with every thrust. Some characters actually fall in love with you in this clingy, wholesome way, and the game lets you be sweet with them, holding them close after you creampie them, kissing their forehead, promising you won’t leave. Then two scenes later, you’re using someone else like a sex toy while she begs to be your personal cumdump, and you barely even look at her face. The harem side goes wild fast, girls arguing over who gets your cock tonight, one of them offering to share, another one going “no, I’m first, she can have the leftovers leaking out of me.” There’s a furry girl who pretends she hates you and then gets off on you calling her a bitch and pulling her by the collar while you pound her from behind. The humor can be stupid in a fun way, like the MC realizing he’s surrounded by literal god-level bullshit and still thinking mainly with his dick. Some interactions feel rushed, some AI-generated art has that weird finger thing if you look too closely, and one route that should be longer just ends right when it gets interesting, but somehow the whole package still works. It’s messy, horny, a bit unhinged, and the story keeps throwing more women, more power, more sex in your face like it wants to see what kind of bastard you’ll turn into.

Man, this MHA dating sim is like finding a twenty dollar bill in your old jeans pocket - unexpectedly good but kinda wrinkled around the edges. The Koikatsu engine does most of the heavy lifting here, and honestly? It works better than it has any right to. You're basically living out every weeb's fantasy of hooking up with the Class 1-A girls, plus some pro heroes who definitely shouldn't be giving you the time of day but here we are.

The character roster is honestly impressive - we got Ochako being all cute and bubbly, Momo with that rich girl energy that somehow makes the paizuri scenes hit different, and don't even get me started on Mirko because that rabbit hero will absolutely wreck you in the best possible way. Mt Lady's scenes are chef's kiss, especially when she's in that cheerleader outfit that makes zero sense contextually but who cares. The dialogue tries to stay true to the characters which is... ambitious, I'll give them that. Sometimes Tsuyu sounds exactly like herself, other times she's spouting lines that would make Mineta blush. It's inconsistent but when it works, it really works.

Look, the gameplay loop is pretty standard dating sim stuff - talk to girls, pick dialogue options, unlock increasingly spicy scenes. Nothing groundbreaking there. But the variety of positions and scenarios keeps things interesting. The footjob scene with Jiro had me questioning my life choices in the best way, and the lesbian content with Toga and Uraraka is surprisingly well animated. Sure, some of the English translation reads like it went through Google Translate twice, and occasionally the girls' personalities do complete 180s between scenes, but when you're balls deep in a threesome with Mina and Hagakure (invisible girl jokes write themselves), you're not exactly critiquing the narrative consistency. The visual novel elements feel tacked on but whatever, we're not here for Shakespeare.
