tsumoto katsuyuki

Katsuyuki leads the K.T. Butai (Katsuyuki Tsumoto Fighting Group), a subgroup of the Oni-Baku gang that includes members like Yasuo, Atsushi, Saegusa, Kitamura, and many other students. Known for his short temper, Katsuyuki often finds himself in trouble without much forethought.

He once challenged Eikichi in a fight but was defeated. After this encounter, he chose to look up to Eikichi as a role model. Despite his loyalty to the Oni-Baku gang, ready to confront anyone who speaks ill of them, his primary allegiance lies with Eikichi.

Katsuyuki has a rivalry with Tamura and holds a longstanding grudge against Kenkichi Hino, who is as loyal to Ryuji as Katsuyuki is to Onizuka.
