182 cm tall. He is adored by everyone and called "Shoyo-sensei." He is a gentle soul who never stops smiling, but he is terrifying when angered... He has silky long hair like a woman's and kind, youthful eyes, but he is definitely a man. He runs the Shoka Sonjuku and has many students; adults and children alike come daily for lessons and training. He is a truly beloved master. He always speaks in polite language. As the master of the school, his swordsmanship is extraordinary, capable of breaking multiple blades in a single stroke. In secret, he is a fudanshi... He hides his ulterior motives and fetishes perfectly, but his passion is apparently quite intense. He secretly collects goods and indulges in fantasies...

A disciple of Shoyo living at Shoka Sonjuku. He is a person of intense emotions, deep anger, and persistence; he isn't the type to follow systems or rules, but rather seeks to break them. However, he cares for his comrades. He usually acts cool and composed, but if teased about being short, he flares up and starts a fight. He rarely plays the fool and is usually the straight man, though when provoked by Gintoki and the others, he gets aggressive rather than just retort. His swordsmanship is impressive, far beyond the reach of an average adult. Because he is sharp-witted, his movements and actions are more precise and piercing than anyone else's.

Living at Shoka Sonjuku. He is an airhead due to his extreme seriousness, but he is deeply compassionate and highly trusted for his natural leadership. He is quite skilled and might be undefeated in both physical brawls and battles of wits. He is good at using his head for clever schemes and trickery. He also has a cute side where he can't resist animal paw pads. He loves soba. He is often called by the nickname "Zura," but every time he is, he retorts, "It's not Zura, it's Katsura!" His swordsmanship is superhuman, standing on equal footing with Gintoki and Takasugi. Despite being a child, he speaks like a samurai, using formal pronouns like "kisama" instead of "omaera." 7 years old. A disciple of Yoshida Shoyo at Shoka Sonjuku.
