My guy comes back from some trip and his friend is dead. Not like, oh no sad, but proper murdered. And suddenly there's angels? And a harem of course, because why wouldn't there be. The game throws you into this weird mix of murder mystery and supernatural horniness that honestly shouldn't work but kinda does if you don't think about it too hard. The opening scene sets it up like some serious noir thing, rain and moody music, then five minutes later you're accidentally walking in on some milf changing because the game thinks that's still peak comedy in 2024.
The 3DCG is... a choice. Characters move like they've got something stuck up their ass, stiff and awkward, but the sex scenes are animated enough to get the job done. There's this one scene with a teacher where the physics go completely mental, tits moving in ways that defy biology, and I laughed so hard I forgot I was supposed to be horny. The exhibitionism stuff sneaks up on you too, like you'll be investigating clues about the dead friend and suddenly you're fucking in a classroom with the door wide open because why not. The game doesn't even acknowledge how unhinged that is.
The sex toy integration is weirdly specific. Like someone on the dev team really had opinions about vibrators and made sure you'd know about them. There's a lesbian scene between two side characters that comes out of nowhere and the male protag just... watches? For plot reasons apparently. The humor lands sometimes, usually by accident, like when a serious dramatic reveal about the angel lore gets interrupted by a panty shot. I can't tell if the game knows it's ridiculous or thinks it's deep. The mobile version runs like ass though, crashed twice during a threesome which is just cruel. The harem management stuff is whatever, standard visual novel choices that don't really matter except for which hole you see first.
