Kazakiri Hyouka

Kazakiri Hyouka (風斬 氷華) is Index's first "friend" in Academy City. She is gentle, quiet and shy. She has a tendency to cry easily. Not much is known about her aside from the fact that she was an overachiver at Kirigaoka Girls' Academy, according to Aisa.

Appeareance
Hyouka has long, brown hair and golden coloured eyes. Most of her hair reaches down towards her lower-back, but a part of it is tied off to the side of her head and left hanging down. She wears large glasses that seem to hide her timid looks. She wears a school-designated blazer and skirt, and accenting these is a red necktie. She also is characterized by her large breasts.

Abilities
Her ability is Counter Stop (正体不明). Details about her level are unknown, but it was mentioned that she was among the top psychics at the Kirigaoka Academy for Girls, though the academy ranks the students on their ability's rarity rather than how powerful they are. 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 own weight.

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 'District' $$i$$ (or the Imaginary Number District). Aleister Crowley says Kazakiri, along with Last Order and Accelerator are all part of his 'Key' to the completion of Artificial Heaven.

FUSE=Kazakiri
ヒューズ ＝ カザキリ is Kazakiri Hyouka in "artificial angel mode". In this mode Hyouka acquires several pin shaped wings, whose total lengths vary from 10 meters to 100 meters, and a halo around 50 centimeters in diameter. On the exterior of the halo are pencil-like rods that appear infinitely, they seem to appear and disappear at a rapid pace. In this form, she is referred to as FUSE=Kazakiri. According to Vento of the Front, in Christianity, terms like 'FUSE=Kazakiri' bears similar meaning to a 'Fallen Angel' that has turned away from God, and is the most abominable being that can exist.

FUSE=Kazakiri is created with the input of a code (virus) in Last Order, which Academy City named 'ANGEL'. When the code is active the SISTER clones are physically immobilized. Later in Volume 20 Aiwass allowed Hyouka to go into this mode without the 'ANGEL' code, by asking the SISTER clones for assistance.

While in this form, Kazakiri has demonstrated she can fire a beam-like attack that can reach up to several tens of Kilometers, and put up a force field around people to protect them from all harm. In volume 20 she can fly at several times the speed of sound, and summon a sword made of pure energy at will, fueled by her determination to help Index.
