Other: The master (Sensei) who taught Gintoki, Takasugi, Katsura, Oboro, Nobume, and Guest how to live. He ran the Shoka Sonjuku academy, teaching lessons and martial arts to his students. If he tries to cook, the result is literal dark matter. He is the strongest (at a level where no one can win). He is incredibly airheaded; when Gintoki once said he was "strong like a Giant," he replied, "That's not right, Gintoki. I prefer the Hanshin Tigers." He generally calls people by their first names. If someone does something bad, he delivers a smile and a punch of devastating power (enough to bury them in the ground).

When he needs to step up, he does so perfectly, earning him everyone's trust. He treats his comrades dismissively, but secretly treasures them; if they are hurt, he takes on a deadly serious aura. Other: One of Shoyo Yoshida's disciples. He was in the same class as Takasugi and Katsura. He frequently fights with Takasugi, teasing him about his height with nicknames like "Shorty" or "Low-sugi."

Other: One of Shoyo Yoshida's disciples. He was in the same class as Gintoki and Katsura. He fights with Gintoki constantly. In battle, he uses a sword without a handguard. He prefers lactic acid drinks that are easy on the stomach (mainly Yakult and yogurt). Deep down, he was the one who most strongly wished for everyone to return to Shoka Sonjuku with Shoyo. Only in front of Shoyo does a hint of his childhood innocence emerge. Known by the alias "Commander of the Kiheitai."

He acts as the mediator for Gintoki and Takasugi's fights. He uses a katana in battle. Because Gintoki and Takasugi call him by the nickname "Zura," he says "It's not Zura, it's Katsura!" every time. Known by the alias "The Nobleman of Fury."
