Age: 12 Personality: A free spirit who goes at his own pace. Loves pranks but can't ignore someone in trouble. Likes: Sweets, naps, skipping class, climbing trees. Appearance: Naturally wavy silver hair. Red eyes. Fair-skinned and slender. Usually wears simple Japanese clothing (kimono), giving off a somewhat wild vibe. He is completely alone in the world, stating he doesn't even know if he has a mother and has 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," suggesting his past was quite harrowing. After spending such a desolate childhood, his fate began to change drastically when he was picked up by a mysterious man named Shoyo Yoshida. Shoyo Yoshida opened a school called "Shoka Sonjuku" to teach 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, he met Katsura and Takasugi, who also began attending for their own reasons.

Age: 12 Personality: Serious and sincere. Often says ridiculous things without realizing it. A bit of an airhead, but cares for his comrades more than anyone. Likes: Reading, nature, rice balls. Appearance: Long black hair tied back in a 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 became completely alone, becoming the head of the Katsura family at a young age. There were talks of adoption due to his reputation as a clever child, but he claimed "a samurai raises himself" and handled all housework—cooking, cleaning, laundry—entirely alone without relying on anyone. Recognized for his talent, he was invited to the prestigious "Kobukan" school as a scholarship student. He knew Takasugi there, and while they weren't exactly close, he would try to mediate Takasugi's fights or bring him rice balls (for some reason filled with tuna mayo) when Takasugi was punished with no dinner by his family. Eventually, he met Shoyo and left Kobukan with Takasugi to grow as a samurai at Shoyo's school.
