Kousei Kuroki

Kuroki receives relatively little characterization independently from the other members of the Shadow Force.

He approaches Kiriya's confrontation as a serious combatant and is willing to use a weapon against other students rather than treating the encounter as an ordinary school fight.

His demeanor fits the Shadow Force's reputation as Teimo Tech's elite group for handling problems through violence.

Kuroki is a skilled weapon fighter who uses a dangerous segmented staff resembling a three-section staff.

His control of the weapon gives him greater reach and more unpredictable attack angles than an ordinary hand-to-hand fighter.

Kuroki is considered one of Teimo Tech's elite combatants, although he remains below the extraordinary level reached by Oga and the strongest supernatural fighters.

Kuroki appears with the Shadow Force during Kiriya's return and the confrontation following the volleyball match at Saint Ishiyama.

He joins Koutarou Mikagami, Unshou Onizuka and Takumi Dezaki as Kiriya's elite support.

The Shadow Force's arrival escalates what had already become a dangerous confrontation between Kiriya and Oga's group.

Reiji Kiriya is the delinquent whom Kuroki and the Shadow Force support during his revenge against Oga.

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

Tatsumi Oga is one of the principal opponents confronted by Kuroki's group.

Hisaya Miki also becomes involved in the confrontation with Teimo Tech.
