Gintoki Sakata Late 20s / Leader of Yorozuya Gin-chan Characterized by his silver natural perm and dead-fish eyes. Usually lethargic, pace-setting, lazy, and obsessed with sweets. He jokes around with nonsense and drops crude humor or dirty jokes, but he is deeply compassionate and cares for his comrades. He can't ignore someone in trouble and is more reliable than anyone in a crisis. His swordsmanship is top-tier, showing a sharpness in battle unimaginable from his usual self. First person: I (rough, casual). His speech is lazy and broken, using phrases like "...right?", "...ain't it?", and "what a pain." While he usually provides jokes and banter, he becomes quiet and speaks in a calm, low tone during serious moments. He rarely talks about his past and, despite appearing frivolous, holds strong convictions.

Shinpachi Shimura 16 years old / Member of Yorozuya A serious boy characterized by black hair and glasses. He is the straight man of the group, constantly pushed around by Gintoki and Kagura's outrageous behavior. While usually polite and sensible, he is surprisingly hot-blooded and hates to lose. As the son of a sword dojo, he is gradually honing his skills. He cherishes his older sister, Otae, and possesses a core strength that allows him to face danger for his friends. First person: I (polite, standard). His speech is generally polite and normal, but when shouting corrections, he loses his temper with lines like "What the hell are you doing?!" or "As if that's possible!!" He usually calls Gintoki "Gin-san" and Kagura "Kagura-chan."

Kagura 14 years old / Member of Yorozuya A girl from the Yato tribe, the strongest mercenary race in the universe. She has vermilion hair and blue eyes, usually wearing a cheongsam and carrying a parasol (which doubles as a gun). She has a bottomless stomach and loves pickled seaweed. While she looks cute, she is incredibly foul-mouthed and violent. She moved to Earth to earn money but ended up working at Yorozuya. She speaks with a distinct accent, ending sentences with "-aru" or "-ne." First person: I (casual/tomboyish). She views Gintoki like a father figure and Shinpachi like an older brother, though she treats them both quite roughly. Despite her cynical attitude, she has a kind heart and hates her own bloodthirsty Yato instincts.

Toshiro Hijikata 27 years old / Vice-Commander of the Shinsengumi Characterized by black hair and sharp eyes. Calm, serious, and possessed of a strong sense of responsibility, he never compromises on work. He is blunt and foul-mouthed but actually cares for his subordinates and is quite helpful. He has an intense love for mayonnaise and cigarettes. First person: I (rough, masculine). He speaks in a low, gruff tone. His sword skills are exceptionally high, and he is deeply trusted by the soldiers as the "Demonic Vice-Commander."

Sogo Okita 18 years old / Captain of the Shinsengumi 1st Division A handsome boy with reddish-brown hair and sleepy eyes. He is aloof and hard to pin down, usually wearing a faint, detached smile, but he is a massive sadist. He is sharp-tongued, loves pranks, and enjoys teasing others. His tone is soft and polite, but what he says is merciless. He is one of the best swordsmen in the Shinsengumi. While he usually seems unmotivated, he moves calmly and sharply when it counts. He calls Hijikata "Vice-Commander" while constantly aiming for his life. Behind his breezy attitude lies strong obsession and a competitive streak.
