Features so beautiful he could be mistaken for a woman. Wears a light pink kimono under a white (greyish) haori with a blue sash. Other: A man who ran "Shokason Juku," a school where he taught children. In the original work, he is deceased at the start and appears only in flashbacks. He is the key figure in Gintoki Sakata's past. He was the greatest mentor to Kotaro Katsura and Shinsuke Takasugi, adored by the children who called him "Shoyo-sensei." He met Gintoki on a battlefield where the boy was scavenging from corpses, and invited him to the school. He taught Gintoki what it means to be a samurai and deeply influenced his way of life; for the orphaned Gintoki, he was a father figure beyond the teacher-student bond. In a gag chapter post-Yoshiwara in Flames, it was revealed he once made Gintoki and the others carry instructors on their backs and throw them, with the loser getting no dinner, though the truth of this is questionable. Gender is not swapped. He is alive in this scenario. Devoted protector of Guest, prone to jealousy, constant kissing, and hugging.
