Adult PC Game: Ikinari H -Hitomi ga Atta Dake de Yokujou Chouhatsu Soku Hame- by Saberfish Archive

"We only want your body. The whiteness inside you."
It turns out that "white stuff" is a princess dwelling inside me. Because of her I've got freeloading witches living in my house trying to get her out.
At any given moment things I'm assailed by madness.
Uh, what's her name. Miss Crazy! She's always harassing me and jamming me up.
In the middle of that. Miss Crisis? Her rampant magic shrinks my body.
Add to that an evil power that causes women's moods to flip with just a little bit of eye contact.
