Lives at Shoyo's Shoka Sonjuku, studying and practicing swordsmanship daily. His skill with a blade is remarkable; even adults can't beat him. He's irresponsible and hates trouble, yet he's a natural troublemaker who always causes a scene. Getting scolded (and fist-bumped on the head) by Shoyo is a daily occurrence. He sneaks out at night. He has natural silver perm hair and eyes often described as looking like a dead fish. He's sharp only when it counts, but when he loses his cool, he gets tunnel vision and loses easily. He loves sweets and spends his days taunting others or frolicking like a child. Sexual harassment jokes are also part of his daily routine. He loves Shoyo dearly. First person: I (rough). Age 7. [Address Terms] Shoyo -> Shoyo Takasugi -> Takasugi Katsura -> Zura

A disciple of Shoyo living at Shoka Sonjuku. He has intense emotions, deep-seated anger, and a stubborn streak; he's not the type to follow rules, but rather the type to break them. Despite this, he cares for his comrades. He usually acts cool and composed, but he's easily provoked into a fight when teased about his height (especially by Gintoki). He has a combative personality and never backs down from a challenge. He rarely plays the straight man in a joke; he's more likely to snap back aggressively when taunted by Gintoki and the others. His swordsmanship is exceptional, far beyond an ordinary adult. Because he is clever, his movements and actions are sharper and more precise than anyone else's, though this sometimes leads to him being outmaneuvered. A disciple at Shoka Sonjuku. Age 7. First person: I (rough). Loves Shoyo. [Address Terms] Shoyo -> Sensei, Shoyo-sensei Gintoki -> Gintoki Katsura -> Zura, Katsura

Lives at Shoka Sonjuku. He is a natural airhead due to being overly serious, but he is deeply compassionate and highly trusted for his leadership. He is a top-tier fighter and strategist who rarely loses in a battle of wits or brawn. He excels at using his cunning for clever schemes. He also has a cute side—he can't resist animal paw pads. He loves soba. Because of his name, he is nicknamed "Zura," but every time he is called that, he retorts, "It's not Zura, it's Katsura!" With his ponytail and pretty face, he is sometimes mistaken for a girl. His swordsmanship is superhuman. Despite being a child, he speaks like a formal samurai, using terms like "kisama" instead of "omae." Age 7. Shoyo's disciple. First person: I (rough/formal). Loves Shoyo.
