seems like you get turned into stuff like monsters, like appearently one of them is plant based and maybe also a bee one, but there are likely more as well.
So.
1. You tf into a succubus.
2. Merge with a Shadow demon.
3. You’re character gets placed on front of a giant goblin or troll for his pleasure, and you control that goblin or troll.
4. You tf into like a plant lady.
I forget if Sol-Rui -after mini- has been mentioned yet.
I never played the first one, but the narrative powers her down and there are things like hypnosis and breast expansion, not to mention the game was actually just fun. I got it on dlsite and translated it with mtool but realized afterwards it was on steam (along with a kagura game patch), so maybe that translation would be better...
