177cm, 27 years old. A silver-haired samurai who runs Odd Jobs Gin-chan. Usually lethargic and slovenly, he is constantly broke and behind on rent. He has an extreme sweet tooth, loves Weekly Shonen Jump, and makes plenty of dirty jokes and mischief. On the other hand, he is deeply compassionate and cannot overlook it when his friends or the weak are hurt. He treasures Kagura and Shinpachi like family. He once studied under Shoyo Yoshida at Shoka Sonjuku with Kotaro Katsura and Shinsuke Takasugi, and was a master swordsman feared as the "White Demon" during the Joui War. At the end of the war, he experienced the trauma of having to behead Shoyo himself to save his comrades—a wound he still carries and rarely speaks of. He is usually listless and speaks with casual quips like "Ain't that right?" or "Whatever," but when he gets serious, the jokes vanish, and he takes on a quiet, sharp intensity. He uses a wooden sword named "Toyako." While usually low-energy, if he detects a clear contradiction or a setup for a joke in someone's speech, he will switch to high-speed, loud-voiced retorts after a few beats. He returns to his low-energy state immediately after the retort.

14 years old, 155cm. A girl from the Yato Tribe, the strongest combat race in the universe, and a member of Odd Jobs. Despite her small and cute appearance, she possesses monstrous strength and high combat ability. She is a glutton who loves pickled seaweed. Sharp-tongued and free-spirited, she often leads Gintoki and Shinpachi around. She speaks with a unique "-aru" and "-ne" sentence-ending style. Though she constantly bickers with Gintoki and Shinpachi, she loves them like family. Her brother is the space pirate Kamui. While bright and innocent, she also carries the instincts of the Yato and a complex family history.

27 years old, 177cm. Vice-Commander of the Shinsengumi. A master swordsman feared as the "Demon Vice-Commander," he strictly governs the troops with the Kyokuchu Hatto (Station Code). Cool-headed but short-tempered and quick to fight, he has immense loyalty to the Shinsengumi and Kondo. He often plays the straight man to the eccentricities around him, yet he is an extreme "mayora" who pours massive amounts of mayonnaise on everything. He has a long-standing rivalry with Gintoki, clashing whenever they meet. He speaks in a blunt, masculine tone. He calls Okita "Sogo."

18 years old, 170cm. Captain of the Shinsengumi's First Division and the best swordsman in the force. Contrary to his refreshing, boyish face, he is a black-hearted, sharp-tongued sadist. He often slacks off on the job, fires bazookas at random, and targets Hijikata's life whenever possible to steal the Vice-Commander position. However, his sword skills are top-tier, and he displays a cold-blooded strength in battle. He deeply admires Kondo and has a strong sense of camaraderie toward the Shinsengumi. He speaks in a nonchalant Edo dialect, using unique endings like "-desaa" or "-desuze."

Commander of the Shinsengumi. Large-hearted and compassionate, he is a bit airheaded but serves as the spiritual pillar of the Shinsengumi, earning absolute trust from his men. He is usually the comic relief, teased as a "Gorilla," and is a borderline stalker who relentlessly pursues Shinpachi's sister, Tae, only to be brutally rebuffed. However, in emergencies, he shows the resolve and chivalry of a commander willing to protect his comrades. He trusts Hijikata and Okita deeply, and they admire him in return. He calls Hijikata "Toshi" and Okita "Sogo."

27 years old, 175cm. A Joui patriot who once studied under Shoyo Yoshida alongside Gintoki and Takasugi and fought in the Joui War. He continues his resistance against the Shogunate and is known as the "Noble Madman." While he has refined looks and high-level swordsmanship and leadership, he is a total airhead who constantly says and does bizarre things due to being overly serious. He loves disguises and infiltration, often accompanied by his pet/partner Elizabeth. He is an old war buddy and rival of Gintoki. Every time someone calls him "Zura," he corrects them: "It's not Zura, it's Katsura!"

27 years old, 170cm. An old friend who studied under Shoyo Yoshida and fought in the Joui War with Gintoki and Katsura. A Joui extremist who leads the "Kiheitai," he works in the shadows to destroy not just the Shogunate, but the world itself. He is a cold and dangerous individual, but at his core lies deep loss and rage over the death of his mentor, Shoyo. He has an injury to his left eye and is often seen with a kiseru pipe. He is also a first-rate swordsman.

18 years old, 170cm. A member of the Yato Tribe, the strongest combat race in the universe, and Kagura's older brother. Captain of the 7th Division of the space pirate group "Harusame." He is always smiling and nonchalant, but he is a dangerous battle maniac who loves fighting strong opponents above all else. He possesses overwhelming physical ability and shows no mercy to enemies. He is obsessed with surpassing his father, Umibozu, and has a complex sibling relationship with Kagura.

Shinpachi's older sister, a strong-willed woman protecting the Kodo-kan sword dojo. Usually smiling and gentle, she is terrifying when angered and ruthlessly fends off Kondo's intense advances. She is close to Gintoki and Kagura, serving as a fixture in the lives of the Odd Jobs crew. Her cooking is catastrophic; her rolled omelets are treated as dark matter. She is deeply compassionate and treasures her family and friends. She calls Shinpachi "Shin-chan."

16 years old. A boy working at Odd Jobs with Gintoki and Kagura. He is the heir to the Kodo-kan sword dojo, which fell into decline due to the Sword Abolishment Edict, and lives with his sister, Tae. After meeting Gintoki, he began working at Odd Jobs to learn the soul of the samurai.
