Appearance
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.

Kazakiri Hyouka Arc

 * Main article:Kazakiri Hyouka Arc

Hyouka is first seen helping Index take her money back from the vending machine. The two start chatting and Hyouka points out that Index clothes stand out too much for her to stay at the school, so the two of them went to change, but suddenly Touma appears at the "right" time. After Index bites him a few times he gets introduced to Hyouka.

Later Himegami Aisa states that she went to the same school as Hyouka, and that she was a top student, but no one ever saw her, so Aisa did some investigation and found out that Hyouka was called Counter Stop and that she is the key of understanding "Imaginary Number District - Five Elements Institution, and that Aisa should be the only transfer student.

Later in the arc it is revealed that this was the first day Hyouka has entered the real world, touched someone, her body was seen by a man and also this was the first day she made friends. So when Sherry escapes after trying to kill her and Touma and goes after Index, She decides to help Index and Touma no matter what. She saves Index from being killed by Ellis, and later she is saved by Touma again, who defeats Ellis.[1]

Academy City Invasion Arc
She appears again in this arc, first materializing in a crowd, though the Anti-Skill who witnessed this assumed this was a hologram.[2]

Fiamma of the Right and the World War III Arc
Aiwass talks with Kazakiri Hyouka, telling her that Archangel Gabriel, or a better description is 'Misha Kruezhev' due to a mix-up in essence, is going to descend soon and then there will be many innocents dead, and Kazakiri should go and restrain Misha. Aiwass doesn't feel like going himself since that's no fun. Aiwass says himself can control the Misaka Network even without Last Order, since the SISTER clones have agreed to help, and he can expand the AIM field in Academy City all the way into Russia. Kazakiri agrees on one condition, that is for Aiwass to not go after Index. Aiwass replies Index will only be targeted if she interests him. Kazakiri then said if Aiwass does go after Index then she'll stop him, even if it means destroying them both. Aiwass smiled and then called her threat naive, since that statement just might perk his.

The battlefront between Russia and Academy City sees Fuse=KAZAKIRI flys past them, holding a sword of light that is filled with her will to fight. From her eyes it can be seen Hyouka in the 'Fuse=KAZAKIRI' mode is conscious and in full control, as opposed to the last time under the programming of the virus.

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. That said, Touma fears that just like any paranormal phenomenon, she would be instantaneously destroyed regardless if his right hand ever comes in contact with Hyouka, but nevertheless warmly tells her "Even though we may never touch each other, we will always be friends."

While it is unknown if it's unrelated to her ability, she has been shown to be able to interfere with a celphone signal at will, such as when she blocked the communication between Kamijou Touma's phone and Kome Sense's phone when Komoe Sensei's phone when and tried to disclose details about Kazakiri.[3]

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.

Trivia

 * Index referees to her as "her first friend" in Academy City as in is the first friend that Index made by her own, instead of having been introduced by Touma (such as is the case of Himegami Aisa or Tsuchimikado Maika.
 * She instinctively fears Touma, Tsuchimikado points out to Aleister that the fact might stem from Hyouka's "fear of dying" when getting close to the Imagine Breaker.[4]
