Misao Onizuka

, also known as, is a senior at Ishiyama High School. He is a former member of the Tōhōshinki before his position was apparently replaced by Tatsuya Himekawa. After serving time in juvenile detention, he joins the Poltergeists, where he is currently known to be the pianist.

Appearance
Onizuka is an extremely tall and muscular man who towers over several delinquents. He has dark, shoulder-length hair styled into tied-up dreadlocks and slanted eyes. He has a thin mustache growing into two different parts over his upper lip. He also has a large, cross-shaped scar on the right side of his face that stretches across his rather wide nose.

He wears a dark-colored shirt underneath an open jacket with a chin-length collar. His jacket is light-colored except for a large patch of cloth that stretches across the sleeves. His pants and shoes are of a similar lightness. The former particularly has the same path of cloth stretching down the pants' sleeves. Moreover, around Onizuka's neck is a large chain-like necklace with a squared pendant.

Personality
Initially displayed as a calm individual, Onizuka is actually rather merciless and prone to anger, especially when confronted with former acquaintances such as Shintarō Natsume. Moreover, he is rather arrogant and conceited. Though once regarded as a member of the Tōhōshinki, he now holds those carrying the title with disdain, believing that they, as well as other notable delinquents in Ishiyama, have become much weaker since moving to Saint Ishiyama.

History
Throughout Onizuka's high school years in Ishiyama, he was regarded as one of the Tōhōshinki; moreover, he often clashed with fellow member, Hidetora Tōjō. However, at some point, he was sent to a juvenile detention and subsequently stripped of his status as one of the Tōhōshinki. He was eventually released from the juvenile detention after some time. Later on, Onizuka came to meet Yōhei Nasu, having since served as the freshman's own underling.

Powers & Abilities
Hand-to-Hand Combatant:

Enhanced Strength:

Yōhei Nasu
Despite Onizuka being an older student, who apparently has never served as another's underling, he shows a considerable amount of respect for the freshman Nasu, even asking permission to fight someone whom he is unacquainted with.

Hidetora Tōjō
It was mentioned that Onizuka used to fight with Tōjō throughout his high school years.

Shintarō Natsume
Onizuka particularly finds Natsume to be the most annoying of their "little group". He treats the fellow student with hostility due t to the fact that he has always found Natsume's personality to be irritating: cheerful, composed, yet seemingly confident enough to hold his ground. However, upon being forced to grovel at Natsume's feet, he became astonished that Natsume could have such power, something he compares to being on the same level as Tōjō's.

 * (To Takeshi Shiroyama): "You guys... have gotten pretty weak. The rumors are floating all over the place. Ever since the Tōhōshinki went to Saint, their fangs have been all dull. You guys all played nice together, right?"
