Orochi

A strange girl with strange powers. She is a sort of guardian angel, but it is unknown whether that is her purpose or whether she just does it as a hobby. She does not age and has been alive for centuries, but needs to hibernate every century or so in order to regenerate her powers and stay young. She seems to be immortal. She does have many powers but they require various amounts of energy and difficult spells apparently wear her out. The most frequent ability she uses is to be barely noticeable, which she uses mainly to keep watch over people (for example: sitting in the back seat of their car).
