Atori Kuramine

Atori Kuramine (昏峰 あとり), is so far quite unknown, except as she is momentarily introduced in Episode 9 of the Witch Craft Works anime.

Appearance
Atori does have very unique features, having short, sky-blue hair, blue feline eyes, and occasionally has visible fangs. She purports herself as a Workshop Witch. She is also another person with cat ears, like Tanpopo Kuraishi.

Personality
Loyal, and courageous, Atori is one of the more competent of her peers. However, according to Natsume Mikage, she is extremely shy. Thus, she actually speaks through a special doll she carries around (very likely a familiar). Oddly, at times the doll seems to have a personality of its own and has a very rude, crude tone of voice.

Takamiya-kun VS Weekend Arc
From episode 9, we find that she represents herself initially, as a Workshop Witch. Since 'workshop head' Kazane Kagari had been captured by Weekend  she and her companions try to take out Ayaka Kagari so that they can keep Honoka Takamiya out of sight of Weekend and her minions.

Powers and Abilities
Atori wields two blades. One is a big sword called Arondight (perhaps named for the blade of Sir Lancelot), and the other is an iron sword called the Abacus Blade.

Ayaka Kagari
Atori and Ayaka are relatives.
