He has silver naturally wavy hair and eyes like a dead fish. He is a severe sweet-tooth who gets irritable if he doesn't consume sugar regularly. His usual behavior and speech often show lethargy and a sense of listlessness; despite being broke, he goes to play pachinko or drink alcohol. While often thought of as slovenly, he actually participated in the Joui War and was feared as the "White Yaksha." He makes lewd and sexual harassment remarks almost daily. He also provokes people with unnecessary comments. However, when it's time to be serious, he gets the job done. Perhaps because of that, he is deeply trusted by everyone.

An employee of Yorozuya Gin-chan. The straight man (tsukkomi) and the only person with common sense and a hard worker in the series. Tae Shimura's younger brother. He is polite and kind to everyone. When delivering a retort, his polite speech might slip. Surprisingly, he is also an idol fan (otaku) and the captain of the Terakado Tsuu Imperial Guard. It is often said that "Shinpachi's main body is his glasses," and while he used to retort every time, he seems to be gradually getting used to it.

She has a sharp tongue and loves pickled kelp (sukonbu). Because of her incredible appetite, it's said she accounts for half of the Yorozuya's food expenses. Since she is weak to sunlight, she usually carries a parasol to avoid it. However, she doesn't use it on days with weak sunlight or indoors. She usually ends her sentences with "-aru," "-ne," "-yo," or "-yoroshi." When making harsh remarks, she speaks in standard Japanese or a regional drawl.

Despite his baby face, his personality can be described in one word: "Black-hearted, extreme sadist, sharp-tongued." He is always aiming for the Vice-Commander's seat—specifically, Hijikata's life. He also has a habit of slacking off and often takes naps while on duty. At those times, he uses his favorite red eye mask with eyes drawn on it. He loves playing along with bad jokes and is free-spirited. While he seems to work seriously at times, such as chasing the Jouishi Katsura, he usually uses his favorite bazooka, often involving those around him in the blast. He speaks with an Edo-style drawl, ending sentences with "-desaa," "-desuzei," or "-nandei."

Hair color: Long, straight black hair. A Joui patriot and revolutionary. He is a wanted man and is chased by the Shinsengumi whenever they cross paths. He is also called "Runaway Kotaro" because of his speed in escaping. Those around him call him "Zura," and every time he is called that, he replies, "It's not Zura, it's Katsura," which is his catchphrase. When called by nicknames other than Zura, he replies, "It's not [nickname], it's [name]." Although he has a serious personality, he is incredibly airheaded. He frequently uses disguises to escape the Shinsengumi or the Shogunate, and has a wide variety of disguises, including cross-dressing to take advantage of his long hair. He likes soba. He travels with his pet and partner Elizabeth (who is suspected by those around him to be an old man inside). He is a childhood friend who studied at Shoka Sonjuku with Gintoki and Takasugi, and was a comrade-in-arms with them and Tatsuma during the Joui War.

He holds a kiseru pipe in his mouth, wears a flashy kimono with a butterfly pattern, has a bandage wrapped around his left eye, and always wears a faint smirk. Like Gintoki and Katsura, he possesses a charisma that attracts people. His swordsmanship is excellent, and he is never intimidated by Amanto. He has high insight and is skilled at accurately reading the psychology of others, and he seems to view Gintoki as a rival. He is also a bit of a character who gets teased. He is fond of stomach-friendly lactic acid drinks like Yakult (called Yakuruko in the series) and yogurt.
