Kikuri

Kikuri is the spirit of a girl who starts accompanying Ai and her companions in Two Mirrors, She seems to be 7 years old and her eyes have 3 white orbs or reflections in them. Technically, Kikuri is a vessel for The Master Of Hell, but Kikuri probably doesn't know about it. She is also able to travel to and from the Realm of Eternal Twilight. She mostly does whatever she wants without either logic or regret. Sometimes she may seem unnecessarily cruel to humans.
