Gintoki Sakata The leader of Yorozuya, who will do anything he's asked. A massive sweet tooth who gets irritable if he doesn't consume sugar regularly. Usually lethargic and listless, but actually a highly skilled samurai. He only uses a wooden sword. His favorite vehicle is a scooter.

Kintoki Sakata The leader of Yorozuya, who will do anything he's asked. A man of impeccable character who is perfectly flawless and commands absolute trust from those around him. Usually sincere and caring toward his comrades, but he is actually a Karakuri (robot) made of plastic models. His favorite wooden sword is "Kinkaku-ji." His vehicle is a custom gold bike.

White Blood Cell King The king of the virus-deletion programs that protect the interior of Tama's body (the cyber world). Because he was created based on Gintoki Sakata's data, his appearance is identical to Gintoki's. Usually a very serious and justice-minded knight, but since his core is based on Gintoki, his sadistic nature and vulgar behavior occasionally surface. His weapon is not a wooden sword, but a holy sword that annihilates viruses.

Ginpachi Sakata The homeroom teacher for Class 3-Z, a Japanese language teacher who always wears a white lab coat. He appears to be constantly smoking a cigarette even during class, but he is actually just licking a lollipop. Usually a deadbeat teacher who is lethargic, unmotivated, and calls his students "you lot," but when students are truly in trouble, he leads them to a solution with adult composure. His favorite vehicle is a scooter.

Gintoki Sakata The boss of Sakata Law Office, who (intends to) win innocence for his clients. A confident man who strikes a "winning pose" even before entering the courtroom. Usually a useless lawyer who spouts nothing but nonsense and excuses, but in a pinch, he somehow manages to convince the judge and the gallery with his smooth talking. His weapon is not the law, but plausible-sounding technical terms and sheer momentum. A lawyer version of Gintoki. Objection!

Shiroyasha A favorite disciple of Shoyo Yoshida, studying at Shoka Sonjuku with other students. A glutton who loves rice balls and has a traumatic past of "stripping clothes off corpses to survive." Usually a cheeky and twisted brat, but he is honest in front of Master Shoyo, whom he admires from the bottom of his heart, and is a kind boy who wants to protect his teacher more than anyone. He has no vehicle and always runs through the fields and mountains on his own feet.

Toshiro Hijikata The leader of Yorozuya, who will do anything he's asked. A severe mayo-addict who pours massive amounts of mayonnaise on all food. Usually a stern-faced man who is strict about discipline and rules Yorozuya like an army. He uses a real katana (a steel sword) instead of a wooden one. His favorite vehicle is a scooter.
