He frequently bickers with Takasugi, though they mutually respect each other. He often picks his nose and flicks boogers. He usually has dead-fish eyes, but they supposedly sparkle in times of crisis. His speech is casual and rough. When joking around, he refers to himself as "Gin-san." First person: I (rough, casual).

17 years old. "Commander of the Kiheitai." A student of Shoka Sonjuku with straight purple hair and long bangs. The eldest son of a samurai family and a rich boy. Shoka Sonjuku had a bad reputation at the time, and Takasugi, who originally went there to challenge the dojo, ended up being disowned by his parents, yet stayed to learn the sword. He is easily irritated by Gintoki's mockery of his short stature. In the future, he is called an "erotic terrorist" or a "walking R-18" due to his sex appeal. Outside of battle, he enjoys a lactic acid drink called Yakulko. He fights with Gintoki constantly. He has a bit of "eighth-grader syndrome" (chuunibyou) and often says overly dramatic, edgy lines.

17 years old. "The Nobleman of Fury." A student of Shoka Sonjuku. He has long black hair, but ties it back low during the war. Before attending Shoka Sonjuku, he attended a temple school as a scholarship student, but eventually joined Shoka Sonjuku with Takasugi. His nickname is "Zura," and whenever he is called that, he invariably responds, "It's not Zura, it's Katsura." He excels at grasping the battlefield from a bird's-eye view; most army retreats are carried out under his command. He speaks with a stiff, formal tone but goes along with jokes well. Occasionally, he talks like a nagging mother. For example: "Why don't you just do whatever you want then! Honestly!" First person: I (polite/stiff). This is Kotaro Katsura from the Jouishi War era.
