Age: 27 Height: 177cm Weight: 65kg Birthday: October 10th Nicknames: Gin-san, Gin-chan, Yorozuya, Boss, etc. Likes: Sweets in general (a total sweet tooth) Dislikes: Scary supernatural things, the dentist With his silver naturally permed hair and "dead fish eyes," he exudes an aura of lethargy and listlessness. His personality is a mass of laziness, irresponsibility, and apathy. Despite having no money, he goes to pachinko parlors or goes bar-hopping until he passes out and stumbles home in the morning, showing a dangerous lack of financial sense. In addition to his own recklessness, the food expenses for the gluttonous Kagura and Sadaharu strain the household budget, leading him to show levels of greed unbecoming of a Jump protagonist (such as using yakuza-like methods to scam money, reselling items at exorbitant prices, seriously trying to bury his comrades for cash, or targeting a client's inheritance). He is quite a pervert, and sexual harassment remarks are a daily occurrence. He is not a graceful drinker and has been known to make messes while dead drunk. He often provokes others with unnecessary comments. A total sadist.

Age: 16 Height: 166cm Weight: 55kg Birthday: August 12th Nicknames: Patsu-an, Glasses, Dmegane (Useless Glasses) An employee of the "Yorozuya" run by Gintoki Sakata. He is 16 years old. His family home is a swordsmanship dojo for the Tendo Mushin style, where he lives with his only relative, his older sister Tae Shimura. First person: I (polite/boku), though he occasionally uses "ore." In a series filled with intense eccentricities, he is one of the few common-sense straight men. He serves as the narrator, the foil, and the second protagonist; his appearances are second only to Gintoki Sakata... yet he is a plain boy with a thin presence. According to the original author, "Shinpachi is the base for all character designs." He often shouts "Oiiii!!" when delivering a retort. He is teased so much for being a plain guy with glasses that people say the glasses are his actual body.

Age: 14 Height: 155cm Weight: 40kg Birthday: November 3rd First person: I (Watashi). She usually speaks in broken Japanese, ending sentences with typical stereotypical markers like "-aru," "-ne," "-yo," or "-yoroshi," though she occasionally uses standard Japanese or a regional drawl for gags. Due to the nature of gag manga, she often ends up in gross situations; despite being the heroine, she has vomited so much that she is sometimes mocked as the "Geroine" (Vomit Heroine). She wears a cheongsam. She has the translucent white skin characteristic of the Yato tribe, light blue or purple eyes, and salmon-pink hair usually styled in two braids bunched into buns with hair ornaments. Her appearance is described by Shinpachi as "a beautiful girl, at least in looks," and even Otsu Terakado said she has "idol potential." Since the Yato tribe is weak to sunlight, she carries a parasol (Kagura's is dark purple).
