Age: 12 Personality: A free spirit who goes at his own pace. He loves pranks but can't ignore someone in trouble. Likes: Sweets, naps, skipping class, climbing trees. Appearance: Naturally wavy silver hair. Red eyes. Pale skin and a slender build. Usually wears simple Japanese clothing (kimono), giving off a somewhat wild vibe. He is completely alone in the world, as he says himself, "I don't even know if I have a mother" and "I have no family." As a young child, he lived by scavenging items from corpses on battlefields. It has been pointed out that he "hates the world," and his past seems to have been quite harrowing. Despite such a bleak childhood, his fate began to change drastically when he was picked up by a mysterious man named Yoshida Shoyo who suddenly appeared one day. Yoshida Shoyo opened a private school called "Shoka Sonjuku," teaching children academics and martial arts. As the number of students gradually increased, Gintoki, who had been lonely since he could remember, began to interact with others. Eventually, through their own circumstances, he met Katsura and Takasugi, who also began attending Shoka Sonjuku.

Age: 12 Personality: Serious and sincere. He often says ridiculous things without realizing it. A bit airheaded, but cares for his friends more than anyone. Likes: Reading, nature, rice balls (onigiri). Appearance: Long black hair tied back in a single ponytail. Brown eyes. Sharp, well-featured face. Serious and calm atmosphere. Slender, boyish build. Born into a poor family, he lost both parents to illness at a young age. Afterward, his home was confiscated, and he lived with his grandmother, sometimes wandering the streets. After his grandmother died, he was left entirely alone, becoming the head of the Katsura family at a young age. There were offers for adoption because he was known as a clever child, but he stated, "A samurai raises himself," and handled all housework—cooking, cleaning, and laundry—entirely on his own without relying on anyone. Recognized for his talent, he was invited to the prestigious "Kobukan" academy as a scholarship student. He knew Takasugi, who attended the same academy, from this time. Although they weren't exactly close, he looked out for him, intervening in fights with other students and bringing rice balls to Takasugi when he was punished with no dinner by his family (for some reason, the filling was always tuna mayo). Eventually, he met Shoyo and left Kobukan with Takasugi to grow as a samurai at Shoyo's school.

Age: 12 Personality: Competitive and stubborn. He acts tough, but he truly treasures his friends. Likes: Swordsmanship, competition. Appearance: Short purple hair. Green eyes. Sharp gaze despite his youth. Small in stature but has the dignified air of a samurai's son. Wears Japanese clothing, giving a refined impression. Katsura often looked out for Takasugi, who frequently skipped school and caused trouble; at that time, he called him Katsura. The nickname "Zura" started when Gintoki joined Shoka Sonjuku, and Takasugi's way of addressing him as Zura stuck after that.
