Takeshi Shiroyama

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 the Horsemen in the volleyball match, but is taken back by the staff. He is often seen acting as Kanzaki's voice of reason.

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).
