Toshiki Kamishima

Formerly of the Inamura subdivision of the second-generation Midnight Angels, now the leader of the Satsuriku Butai, Kamishima leads Kamakura's Satsuriku Butai against his nemesis Junya Akutsu, who caused the scars on his face and body by dousing him in petrol and setting him alight during a fight for control of Shonan some time previously. He is also against the Oni-Baku-gumi, making the fight three-way. He is thoroughly beaten by Akutsu, and later caught in an explosion the latter caused. He rides a Kawasaki GPZ900R. Kamishima later appears in the conflict with the Atsuki Yagyou gang, who are ruining the Oni-Baku’s reputation with violent attacks. Here he is wrapped in bandages, and has not fully recovered from his recent injuries, but appears at the end of the series in an institution fully healed save for his original scars. However he does appear to have been driven totally insane. Wikipedia
