出灰カガリ

Kagari Izuriha is one of the characters in the 2012 Black★Rock Shooter anime. Her "other self" is Chariot.
She is voiced by Eri Kitamura (Japanese) and Haley Bennett (English).

In appearance, Izuriha is depicted as wearing a white sleeping gown and has a very messy hair that comes down all the way down to her hips
She is also permanently bound to a wheelchair, and seems to be associated with a particular doll with brown hair curls.

A childhood friend of Yomi. She is permanently bound to a wheelchair and thus does not attend her school. Yomi seems to be very afraid of her, but continues to communicate with her and allow her into her house.
She is unable to become friends with Mato and hates her. She is also very fond of macaroons. Her obsession with Yomi is extremely possessive, and she seems to have some kind of past incident with her, forbidding Yomi from making any friends, declaring that Yomi is "hers", and demanding that Yomi "take responsibility".

She is not subtle about her like or dislike of someone, offering Mato what she calls the "dirty colors" of her macaroons and giving her an ugly doll. She has her own doll named Mary, which she sometimes talks through.
