This is actually one of two split personalitiies of the main character in a book I'm currently writing. The woman's name is Yuki, and she's actually an android with two seperate personalities, one angelic and one demonic. This, obviously, is the demonic one. Though most of the story is scifi, there's a lot that takes place inside Yuki's mind which is far more in the realm of fantasy. I'm actually working on an update of this character, so I should have another picture in soon. Tell me what you think!
