This thing is a glorious mess of a fever dream. You kick the bucket from overwork, classic isekai setup, and a succubus offers you a deal. Not just any deal, a contract to seduce your way across a bunch of anime universes to fuel her up with sexual energy. The roster reads like someone's meticulously curated bookmark collection: Tsunade, Kurenai, Darkness, Aqua, Kaguya, and a whole lot more. The "more" includes some choices that'll make you double take, like a futa Haku. I'm not even gonna pretend I was ready for that.

The 3DCG is janky in that specific, almost endearing way. Characters look like they were assembled from a very enthusiastic modder's private stash, which honestly fits the whole "contract with a devil" vibe. The animations are there, they do the job. What sticks with me is the corruption mechanic, it's not just a visual change. You get these "devil traits" and a cunning mind to actually work the scenarios, which sometimes means navigating a female domination route you can totally avoid if that's not your thing. Or you can lean hard into male domination. The game doesn't judge, it just provides the tools for your specific brand of degeneracy. One minute you're getting a teasing handjob from Samui, the next you're deep in a group sex scene that somehow involves a pregnant Kushina and it's all part of the plan.

The writing is what it is, a parody that knows exactly what it's doing. It's not winning any awards but it moves with a weird, self aware energy. I got stuck for a bit trying to figure out the exact sequence to unlock the vaginal scene with Wiz, and the UI feels like it's held together with tape. But then you trigger a transformation scene with Tayuya and just... forget about it. The voyeurism bits are a nice touch, letting you just observe the chaos you've caused. It's a power trip wrapped in a parody of a power trip, and somehow the paranormal romance with a succubus is the most grounded part of the whole experience.

So the premise is you die from overwork, classic isekai setup but instead of a truck it's just your body giving up, and a succubus offers you a deal. You go around different anime universes, Naruto, Konosuba, whatever, and you have to seduce characters to generate sexual energy. The whole thing is 3DCG, which I always find a bit uncanny, like the models are all shiny in that specific Daz3D way where everyone looks like they're coated in a thin layer of oil. Tsunade's chest is massive, obviously, but the physics on it are weirdly stiff considering this is an animated game. You'd think with all the focus on big tits they'd get the bounce right.

I spent way too long in the Konosuba section because Darkness is there and her whole deal translates surprisingly well to this format, all her flustered embarrassment while still clearly wanting it. There's a corruption mechanic that's barely explained, you just kind of click options and sometimes a bar fills up. The male protagonist has these "devil traits" which I think are just dialogue choices but the translation is so rough it's hard to tell. At one point the text said something about "using your cunning mind" and then the next line was a grammatical disaster about Hinata's "gentle fist technique" being applied in a way that made me laugh out loud. Not sure if intentional.

The voyeurism tag is accurate, there's a scene with Kurenai where you're watching from outside a window and the animation loops in this hypnotic, slightly broken way. Her handjob technique looks more like she's trying to start a lawnmower. I wish the futa content was more prominent, it's tagged but you have to dig through specific routes and I kept getting locked into male domination paths when I wanted the opposite. The pregnancy stuff is there too, which I didn't expect, and it's handled with all the subtlety of a brick through a window. One minute you're doing oral sex with Aqua, the next there's a timeskip and she's heavily pregnant and crying about something the translation didn't bother to clarify. The whole thing feels like someone's half-remembered fever dream about these characters, which I guess is the point of a parody game. The Kaguya-sama section has a group sex scene that completely misunderstands the source material's tension but honestly that made it funnier.
