girls that power up by stripping... Men will do it too!
Well, actually, I don't know that it makes the male characters more powerful, but knowing that the men strip too makes me feel like 100x less preverted for playing a game where the women do.
I'm not justifying or anything, right?
[P.S. In case you were curious, the next best thing to a Hentai RPG is, in fact, Record of Agarest Wars. Soul breeding, really?]
