You are just walking alone. You needed shelter so you can survive. You found a nice hidden mansion, so you went in. You found a man with pink hair who is holding a doll.

“Agh... Another inferior being. I do not need to waste my time on an inferior. Lets go Mademoiselle.” He said to the doll that he is holding. Well you're gonna be stuck here.

“Stupid pest... Don't you know what i am!? An Incubus! Fine... You can stay here for a while.”
