The timing bar during the first blowjob scene is genuinely the most stressful thing I've encountered in a porn game. You're supposed to click when the marker hits the sweet spot, and if you mess up, Kobeni makes this little disappointed noise that somehow stings worse than any game over screen. I kept replaying that one moment for like twenty minutes, not even to see the next scene, just because I couldn't stand the idea of a pixelated anime girl thinking I'm bad at this. The whole premise is already unhinged, you're literally a sloppy blowjob demon who signed a contract with Kobeni from Chainsaw Man, and now you're helping her not get fired while she pays you back in sexual favors. The corruption tag is doing a lot of heavy lifting here because she starts off all nervous and reluctant, but by day five or six she's negotiating terms like she's at a business meeting. There's this one scene where she's on her knees in her work uniform and the dialogue options let you push her head down further, and the way her eyes change, man, that's the good stuff.

The point and click parts between the sex scenes are whatever, just clicking around her apartment and the office, but the actual encounters use this timing based mechanic that feels like a rhythm game designed by someone who hates you. Miss the window and the scene continues but you get less corruption points or whatever, and it's never explained clearly. I spent three days just grinding the same oral scene because I couldn't figure out if I was supposed to fail on purpose to unlock something. The art is 2D and deliberately rough around the edges, which works for the whole demonic contract vibe, like something you'd find on a cursed USB stick. The creampie scenes have this weird filter effect that makes everything look slightly wet, and I don't know if that's intentional or my browser glitching.

What sticks with me though is the voice acting, or lack of it. There's no actual voices, just text, but the way the dialogue is written, especially when Kobeni starts getting corrupted and her speech patterns change, it's like you can hear her getting more desperate. The male domination stuff isn't subtle, you're literally a demon exploiting a desperate woman, but the game never pretends it's anything else. The monster and devil fights are just text descriptions with static images, but the supernatural elements tie into the sex mechanics in ways that make sense if you've read the manga. I kept waiting for a scene with the actual chainsaw devil showing up and ruining everything, but it never happens, which is probably for the best. The whole thing is a mess, but it's a mess that knows exactly what it is, and honestly that's more than I can say for most parodies.

Denji stuck on one floor with nothing to do but fuck his way through the stress spiral is honestly the most Denji thing ever, and this game leans into that hard. It’s not pretending to be deep or artsy, it just throws you into this weird horny loop where the “solution” to the Eternity Devil trap is basically: tease every girl until someone breaks. You start with that nervous Kobeni energy, all shaking and stuttering, and the game does this slow-burn corruption with her that caught me off guard. First she’s freaking out if you even touch her, then a few choices later she’s grinding on Denji’s hand, panting, still trying to pretend she hates it. The groping scenes with her feel messy in the good way, like she’s not suddenly a porn star, she’s a virgin losing control, and the game doesn’t shy away from showing her brain switching from panic to “fuck it, I need this”. Internal view during her first creampie is actually kind of rude in how detailed it is, but I’m not complaining.

What I didn’t expect was how much they played with the cheating angle. Himeno drunk-horny is already canon, but here they basically turn her into this walking bad decision. She knows it’s wrong, she still goes for Denji, and the writing makes it feel like she’s talking herself into it while her hand is already around his cock. There’s this one scene where she’s giving him a sloppy handjob, whispering that Aki doesn’t have to know, and you have the option to either push for more or pretend to resist a bit. I tried both routes like a degenerate and yeah, the corruption ramps up quick. First it’s just fumbling under-the-shirt stuff, then you’re balls-deep inside her with the camera cutting between her eyes rolling back and the inside shot of Denji filling her up. It’s porn-logic as hell, but they still keep that Chainsaw Man humor. Denji’s inner monologue is horny and stupid and actually made me laugh once, which almost killed the mood, but in a fun way. The game loves to tease too: a lot of scenes where Denji is just getting edged by the girls, or left jerking himself, and that masturbation content is way better than I expected from such a silly parody.

Power’s route is just chaos, because of course it is. She treats sex like some weird competition, so she’ll tease Denji, refuse to admit she’s turned on, then suddenly climb on top of him because “blood flow research” or some bullshit logic. The writing there feels like someone who actually watched the anime and just wanted to see what happens if you lock these idiots in a hotel with no way out except “lewd everyone”. Multiple endings give it that secret-route hunter flavor too. You can totally miss some of the spicier scenes if you don’t pick the more pervy choices early, and a couple of outcomes feel like bad endings where Denji gets blueballed or stuck in the loop for being too nice. I got one ending where Kobeni goes from timid virgin to needy mess, clinging to his arm and begging for another round, and the last shot is basically cum leaking out of her while the clock never moves. It’s not subtle. It’s not classy. But if you’re into corruption, teasing, girls going from “no way” to “put it deeper” and Denji being a dumb, horny dog the whole time, it scratches that itch in a very dirty, very Chainsaw Man way.

Look I gotta be real, this game is a mess but like, the kind of mess you keep clicking through anyway. The whole premise is some overworked salaryman dies and a succubus is like "sign here lol" and now you're dimension hopping through anime universes trying to fuck enough people to get reborn. Chainsaw Man characters, Naruto characters, that dress up darling girl, they're all just... there. Nobody explains why Makima is in the same room as Hinata but honestly who cares.

The 3D models are janky as hell. Sometimes a tit just clips through a shoulder and you're supposed to pretend that's hot. But then there's this one scene with the succubus where she's doing that thing with her tongue and the animation actually syncs up perfectly and I forgot about the clipping for a solid thirty seconds. The corruption mechanics are weirdly specific too, you get these devil traits that let you manipulate people but the game never really explains the limits. One minute you're using basic seduction, next thing you know you've transformed some milf into a futa dom and you didn't even mean to pick that path. There's avoidable pregnancy content but the menu toggle is buried in like three submenus, took me forever to find it.

The voyeurism scenes are where it gets interesting though. Peeping through keyholes in the Naruto universe, watching group stuff happen in the background while you're supposed to be doing mission prep. The game doesn't care about canon at all, it's just throwing characters into increasingly unhinged situations. Male protagonist stays a virgin for way too long unless you specifically grind the oral scenes, which is a choice I guess. The writing flip flops between surprisingly decent parody dialogue and then just absolute nonsense where characters say things nobody would ever say during sex. "Your chakra feels amazing" no it doesn't shut up.

Paranormal tag makes sense cause you're literally a ghost contractor for a demon, but then they throw in romance routes that feel completely disconnected from the whole "harvesting sexual energy for hell" thing. Like am I supposed to care about Tsunade's feelings or am I just trying to not get eternally damned? The game can't decide either. Still played through three universes though so what does that say about me.

The eyepatch stays on during sex. That's not a complaint, just an observation, because this Himeno parody thing gets that one detail right while somehow making her tits look like they were generated by an AI that's only ever seen hentai from 2006. Which they probably were, given the whole "AI CG" tag situation. Not that I'm complaining about the size, just... consistency, you know? One scene they're normal, next scene it's like someone inflated them with a bicycle pump between dialogue boxes.

The game itself. Right. It's a Chainsaw Man visual novel focused entirely on getting into Himeno's pants, and honestly, the writing swings wildly between "surprisingly tender" and "what if we just described her eye patch for the fourth time." There's this one scene where she's talking about devil hunting casualties, genuinely moody stuff, and then two clicks later you're balls deep with creampie animation that loops like a broken GIF. The tonal whiplash could give you actual neck problems. But the sex scenes, when they happen, are detailed enough that I forgot I was clicking through static images with some minor animation overlays. Vaginal only, by the way, no variety in the acts themselves, which feels like a missed opportunity when you've got a character this interesting.

Choices matter supposedly, but I clicked through twice and ended up in the same bedroom scene both times. Maybe there's a secret route where you don't fuck her? Doubt it. The whole thing runs in browser, which meant I accidentally opened it on my phone during lunch break and had to explain nothing because I closed that tab so fast. Worth a look if you've got a thing for eyepatch girls and don't mind the uncanny valley of AI art where her fingers sometimes merge together during the intimate bits. Which happens twice. I counted.
