Seikichi Kuroda

Once the self-proclaimed protector of Hekikuu High, this intimidating-looking student struggles with a submissive past under his predecessor's command. Though he possesses significant physical strength and a heavy punch, his tendency to panic and his simple-minded nature often lead to humiliating defeats. Alongside his loyal lackeys, Ooshita and Tokiyama, he attempts to maintain a tough delinquent persona despite his secret crush on Ryoko and his underlying vulnerability.
