Takumi Dezaki

Dezaki receives little individual characterization beyond his association with the Shadow Force.

His appearance distinguishes him from the group's more heavily built members, but the story does not develop a separate motivation, rivalry or personal philosophy for him.

He nevertheless willingly participates in Kiriya's violent confrontation with the Ishiyama students.

Dezaki belongs to Teimo Tech's Shadow Force and is therefore treated as one of the school's elite fighters.

No named martial art, supernatural ability or individual signature technique is established for him.

His combat role is primarily collective, adding to the fighting strength Kiriya brings against Oga's group.

Dezaki appears during the confrontation following the growing dispute involving Kiriya, Oga and Hisaya Miki.

He joins the other Shadow Force members as Teimo Tech's elite reinforcements.

His role remains limited to this faction rather than expanding into an independent storyline.

Reiji Kiriya is the delinquent leader whom Dezaki supports.

Koutarou Mikagami, Unshou Onizuka and Kousei Kuroki are Dezaki's fellow Shadow Force members.

Tatsumi Oga is a primary opponent of Kiriya's faction.

Hisaya Miki has a personal history with Kiriya that drives the conflict involving the Shadow Force.
