Takeshi Shiroyama

Takeshi Shiroyama (or Shiro-chan, as Natsume nicknames him) is Kanzaki's most devoted underling. A strong, tall third-year, he is nevertheless easily defeated by Oga with a single shot to the chin.

Even after his humiliation by Kanzaki and the dissolution of the latter's gang, he remains attached to Kanzaki. Later, when he is sent to the hospital by St. Ishiyama students, Kanzaki visits upon him. He escapes the hospital to support Ishiyama against Rokkisei in the volleyball match, but is taken back by the staff. He is often seen acting as Kanzaki's voice of reason.

Appearance
With light tanned skin and dark eyes, Shiro stands out due to his height and large well-muscled physique. His hair is braided into pigtails tied by yellow bows. Shiro also has two scars on his left cheek, similar to Miki's. He is often seen wearing a school uniform.

Abilities
Due to his large size, Shiroyama is quite strong and durable and has good fighting skill, however he is nowhere near as strong as Oga or even Kanzaki. A testament to his endurance was when he took a massive barbell to the head and survived, even after being hospitalized he manage to get back on his feet and go all the way back to school to cheer Kanzaki on during the volley ball match between Ishiyama and the Rokkisei, although he did still suffer from his injuries. During Zenjūrō Saotome's training of some of the Ishiyama delinquents, Shiroyama is shown to now be able to fight on par with Tatsuya Himekawa (who has also been partaking in the same training).

Kanzaki
They are still friends, but Shiro is beginning to stand up for himself more.

Natsume
Natsu treats Shiro more fairly, and after everyone finds out he's actually way stronger than the lower-tier guys like Kanzaki (just hiding his power) Kanzaki seems like a less intimidating boss by comparison.
