All the girls are making positive impressions with me. I especially love Veronica and the devilgirl. In all seriousness though i don't think the devil will have a charming personality. I might be wrong of course but i often see them way too pushy, lascivious for their own good actually. It just makes them slutty and less seducing. I'm still looking for that truely dangerous succubus who is cut above the usual breed and plays hard to get, wears the mask of sincere care, pretending believably to have true feelings toward the victim, romantic and sensual instead of just spreading her legs. The Famme Fatale type.
Something like that was presented in Dark Messiah, could never tell right untill the end if she was honest or not as she was succesfully upredictable, confusing with her sometimes romantic confessions.
