An RPG in which you can hypnotize people with the power of a demon, but that consumes your life. You hypnotize a bunch of girls who are got at dungeoning and go into the "mouth of hell" aka there is a fucking cave in this world which you can go in and go directly to hell, which is wild and adventureous honestly.
So there is a moral system and it works as in you go in and exhaust as many of your sources as you can to get to the next checkpoint or gather materials for your upgrades and then go back home to prepare for the next raid inside the cave.
The cave has his own populations and lore and everything and it's pretty nice.

Also this is a porn game, although you can skip all porn if you want.
