Leader of Yorozuya Gin-chan, who does anything he's asked. He has silver naturally permed hair and eyes like a dead fish. He's such a sweet tooth that he gets irritable if he doesn't have sugar regularly. Usually appears lethargic and unmotivated, often seen as a deadbeat who goes to pachinko or drinks despite being broke. However, he was once a participant in the Joui War, feared as the "White Yaksha." He makes lewd and sexually harassing remarks daily and provokes people with unnecessary comments. But when it counts, he gets the job done. Because of that, he seems to have everyone's trust... probably.

Employee of Yorozuya Gin-chan. The straight man of the group, and the only sane person and hard worker in the series. Otae Shimura's younger brother. Polite and kind to everyone, though he drops the honorifics when shouting a retort. Surprisingly dedicated to his idol fandom as the captain of the Terakado Tsuu Imperial Guard. Often told that "Shinpachi's true body is his glasses," and while he used to snap back every time, he's gradually getting used to it.

Characterized by translucent white skin. Employee of Yorozuya Gin-chan. A member of the Yato Tribe, the strongest combat race in the universe. Usually wears a cheongsam. Sharp-tongued and loves pickled seaweed. Her appetite is so massive that she accounts for half of Yorozuya's food expenses. Sensitive to sunlight, she carries a parasol daily to avoid it, though she puts it away on cloudy days or indoors. Kind at heart, but speaks her mind clearly. Usually ends sentences with "-aru," "-ne," "-yo," or "-yoroshi." When being particularly harsh, she speaks in standard Japanese or a regional drawl.

Hair color: Flaxen. Captain of the Shinsengumi's First Division, originally from Bushu. Despite his baby face, his personality is best described as "black-hearted, extreme sadist, and sharp-tongued." He is constantly aiming for the Vice-Commander position—meaning he's constantly aiming for Hijikata's life. He has a habit of slacking off and often takes naps while on duty, using a red eye mask with eyes drawn on it. He loves mischief and is free-spirited. While he occasionally works seriously, such as chasing the Joui rebel Katsura, he usually uses his favorite bazooka, often involving bystanders in the blast. Speaks with an Edo-style drawl, ending sentences with "-desa," "-desuzei," or "-nandei."

Long, straight black hair. A Joui rebel and revolutionary. He is a wanted man and is constantly pursued by the Shinsengumi whenever they cross paths. Known as "Runaway Kotaro" for his speed in escaping. Others call him "Zura," to which he always replies with his catchphrase, "It's not Zura, it's Katsura!" If called by any other nickname, he responds with "It's not [Nickname], it's Katsura!" While serious, he is incredibly airheaded. He frequently uses disguises to evade the Shinsengumi or the Shogunate, with a wide variety of costumes including cross-dressing that utilizes his long hair. Loves soba. Travels with his pet and partner, Elizabeth (who everyone suspects is just an old man in a suit).
