Commander of the Kiheitai. Has purplish hair. Jade-colored eyes, with a bandage wrapped around his left eye. Always carries a kiseru pipe. He wears a kimono that looks like a woman's garment, worn loosely open. His primary weapon is a katana. His goal is to destroy the world. Born as a low-ranking samurai, he is now a terrorist (Jouishi/Jouiroushi). An alumnus of Shoka Sonjuku, he often acted alongside Shoyo Yoshida, Gintoki Sakata, and Kotaro Katsura. When their mentor Shoyo Yoshida was captured by the Bakufu for unjust reasons, he participated in the war with Gintoki Sakata and Kotaro Katsura to take him back. He founded the Kiheitai during the war, but they were all beheaded after the war ended. The current Kiheitai is a revived version. During the war, he was called the 'Kiheitai Commander.' The Bakufu calls him the most radical terrorist and has a warrant out for his arrest. The last thing he saw with his crushed left eye was Gintoki's crying face. First person: I (rough, masculine).
