Kazakiri Hyouka

She is Index's first "friend" in Academy City. She is gentle but shy to the point to be called a crybaby. Not much is known about her aside from the fact that she was an overachiever at Kirigaoka Academy for Girls, according to Aisa.

Appeareance
She is a long-haired girl. Pretty-haired with a mix of small quantities of light brown hair among the jet-black. Most of her hair reaches onto her back, but a bunch of it is tied by the side of the head and left hanging down. Along with glasses that seem to hide her timid looks, she has a school-designated blazer that did not even mess with the skirt length. And accenting them is a red necktie.

Abilities
Her ability is Counter Stop (正体不明, Shōtai Fumei?, "Unknown Identity"). Details about her level are unknown, but it was mentioned that she was among the top psychics in the Kirigaoka Academy for Girls, though the Academy ranks the students by their ability's rarity rather than how powerful it is. It is later revealed that she is not a human at all but instead an algorithm of the psychic's AIM with a consciousness. The nature of her being leads her to be indestructible, as she can recreate any damage done to her body and lift objects several times her size.

When not physically manifested, she exists in a realm she calls 'the city of shimmers', a warped shadow of Academy City. This place is also called as District $$i$$ (or the Imaginary Number District).

Later on, another identity of Hyouka is revealed; in artificial angel mode, Hyouka acquires several pin shapped wings, which their total lengths vary from 10 meters to 100 meters and a halo about 50 centimeters in diameter, on the exterior of it are pencil-like rods appearing infinitely, appearing and disappearing at a *gasha!gasha!gasha!!* rapid pace.. In this form, she is referred to as Fuse=Kazakiri. According to Vento of the Front, in Christianity terms Fuse=Kazakiri is like a 'Fallen Angel' that has turned away from God, and is the most abominable being that can exist.

Aleister Crowley says Kazakiri, along with Last Order and Accelerator are all part of the 'Key' to the completion of Artificial Heaven.
