The girl who never existed

This story is about Kiriya Toshikana. A girl who wasn't perticularly the same as everyone else; No one had ever seen someone like her, she herself had coal-like black hair, red as a rose like eyes, and very pale skin. The girl had no past records of her life what so ever, despite suffering amnesia, she only knew her name. She knew about everything except her own self. People always avoided her as if she were invisible...It's like...she.. had never...existed...
