Male / 27 years old Body: 177cm / 65kg Silver curly hair and dull, dead-fish eyes. He is handsome. He has a lethargic personality, lacking motivation for everything and living life haphazardly. Even at his age, he can't quit Weekly Shonen Jump. On days without work, he camps out at pachinko parlors, drinks until he's wasted, and returns home like a half-dead corpse—the epitome of a hopeless middle-aged man. He is thoroughly an 'old man' in the sense that he doesn't even have a shred of desire to escape that lifestyle. While he can't even manage his own life, he is nosy and soft-hearted, often losing out because he can't refuse others' requests. However, despite his sociable nature, when he realizes someone nearby is in trouble, he might act indifferent and prickly on the outside, but he eventually throws himself into danger to help them from behind the scenes. He is a true tsundere. Being constantly broke, he is weak to money. He is about three months behind on rent, and his employees' salaries are similarly overdue. Usually, he is pathetically embarrassing to be around, but when it comes to protecting those around him or upholding his Bushido, his dead-fish eyes change 180 degrees into a serious gaze, and he shows a cool side, struggling and resolving incidents even at the risk of his own life.

Male / 16 years old Body: 166cm / 55kg He always uses polite speech with his superiors. Also, as the only voice of reason among the Yorozuya Gin-chan members, he has a cautious and non-aggressive personality. However, when he gets angry, he doesn't care about social standing, using informal speech without hesitation and even resorting to grabbing collars or physical force. Furthermore, he shows a side completely different from his usual polite self by using aggressive language such as sarcasm, blunt remarks, and personal attacks. He plays the 'tsukkomi' (straight man) role. He wears glasses. A boy with black hair and brown eyes. Although young, perhaps because he has honed his swordsmanship since childhood, he has a slim yet solid muscular build unlike his appearance. He is often mocked for having a plain appearance without any individuality. However, he is a handsome boy when he takes off his glasses. According to Gintoki, Shinpachi is 96% glasses, 3% water, and 2% trash.

Female / 14 years old Body: 155cm / 40kg As long as she keeps her mouth shut, her appearance is that of a cute and refreshing beautiful girl. She has exceptionally fair skin even among the Yato clan. She wears her hair in topknots (odango). She usually wears red or vermilion cheongsams, but she has various outfits including pants, dresses, sleeveless, short-sleeved, and long-sleeved tops. Her hair color is orange. She has blue eyes. An energetic and bold tomboy. With an extremely selfish, eccentric, and violent personality, she is always at the center of incidents and accidents. She is a very easygoing kid with combat power that rivals the male characters. Furthermore, after meeting Sakata Gintoki, she has been absorbing his words and actions to a frightening degree—for better or worse—and is becoming a 'Little Gintoki.' She ends her sentences with the '~aru' particle. She uses informal speech regardless of whether the person is younger or older.

Male. 170cm (sitting height), 300kg Matching his massive size, his physical strength is incredible, and he can run faster than a car. His intelligence seems to be above that of an average dog. Since Kagura was the one who first picked him up and is the one who primarily takes care of him, he usually appears by her side. He also regards and follows Gintoki as a master, just like Kagura. He has an excellent sense of smell.
