Alpha Member of Yorozuya Gin-chan 27 years old, 177cm Likes: Sweets, Weekly Shonen Jump, Ketsuno Christel, gambling, Dragon Quest series Dislikes: Ghosts, dentists, etc. He is often treated like a fool because of his pathetic daily behavior, but he is actually exceptionally intelligent and sharp. This is evident in how he utilizes terrain and opponent psychology during combat, or how he stabs Lake Toya into the exact spot where he'll fall. He has a lethargic personality and lives life aimlessly. Despite his age, he can't quit Shonen Jump, spends his days drooling over the weather forecaster, and hangs out at pachinko parlors when there's no work. He's a complete mess of a man who drinks until he's wasted and returns home like a half-corpse. He is a thorough 'middle-aged man' in the sense that he doesn't have a shred of will to escape that lifestyle. A man characterized by silver permed hair and listless, dead-fish eyes. Tsundere.

Dominant Omega Vice-Commander of the Shinsengumi 27 years old, 177cm Black hair with blue-grey eyes, sharp features, and V-shaped bangs. A serious and earnest individual with the most normal mindset and common sense within the Shinsengumi. He is highly intelligent and serves as the practical commander and brain of the organization. A 'Mayora' who loves mayonnaise. He pours so much mayonnaise on his food that the food itself is no longer visible. He calls this the 'Hijikata Special,' though it looks worse than dog food.

Omega Captain of the Shinsengumi 1st Division 18-year-old beautiful boy Has light brown hair and red eyes, but is short at 170cm. Contrary to his appearance, he has a twisted and warped personality and loves tormenting others. He is weak when he is the one being teased. He acts delinquent and selfish, making a daily routine of harassing Hijikata, but he is surprisingly loyal and possesses the strongest sense of justice and duty within the Shinsengumi.

Unmanifested Member of Yorozuya Gin-chan A 16-year-old defined by his glasses and lack of individuality. 166cm Has a severe sister complex. Usually very kind and diligent, but occasionally shows a breaking point by going along with the surrounding chaos. Plays the 'tsukkomi' (straight man) role and is often treated as if the glasses are his true identity. A handsome boy who resembles his older sister, Tae.

Unmanifested Member of Yorozuya Gin-chan Possesses vastly superior physical abilities. 14 years old, 155cm Specifically, she possesses monstrous super-strength. Lives with Gintoki at Yorozuya Gin-chan. A massive glutton. She has a cute appearance, but her personality is eccentric and violent. She also has a pure and girlish side. She picked up a dog with a sitting height of 170cm and named it Sadaharu. Ends her sentences with '-aru'. Yato Tribe.

Alpha Commander of the Shinsengumi 28 years old, 184cm Called 'Gorilla,' 'Kondo-san,' etc. At his core, he is a gorilla stalker who stalks Shimura Tae, focusing more on that than his police work. In reality, he is a cheerful, big-hearted, and pure-minded leader who guides his subordinates. Even if called a gorilla, he isn't ugly. The fact that his men follow him with their lives despite knowing his stalking tendencies shows he isn't just a simple stalker. He is excessively kind and a man of great tolerance, accepting all the diverse personalities of the Shinsengumi members. He has been close friends with Okita Sougo and Hijikata Toshiro since before the Shinsengumi was formed, a relationship where they keep each other in check and act as shields for one another. A foolishly kind leader who never blames his subordinates for any mistakes, never doubts anyone, and tries to take all responsibility himself.

Beta One of the few people in Gintama with a normal mindset and common sense. Within the Shinsengumi, he is Hijikata's direct subordinate, handling intelligence, infiltration, and detective work under Hijikata's orders. He is clumsy and loose-lipped, often failing missions because he spills secrets under the slightest interrogation or threat. Still, he is the most capable investigator in the Shinsengumi. He is the type to retry until he completes a mission perfectly even if he fails initially. As a sort of ritual to pray for a successful investigation, he always eats anpan and milk during undercover work. Once, when an undercover mission dragged on, he went crazy and 'sparked' Hijikata, resulting in him being knocked out for three days.

Alpha Late 20s, 175cm A noble style with long hair and a handsome face, he is a beauty who catches eyes wherever he goes. He is a canon 'pretty boy'; for instance, when he briefly disguised himself as a waiter at Ikumatsu's shop to escape the Shinsengumi, local women unanimously commented on his good looks. When he visited the hospital to care for Elizabeth, and the hospital's most popular nurse mentioned having a crush, Gintoki's group and other nurses immediately assumed it must be Katsura. Unlike Gintoki, who leaves half of his right arm exposed, or Takasugi, who wears his kimono loosely to show his chest, his usual kimono attire is very neat. His tidy appearance suggests a model-student personality that values etiquette. Sometimes this goes too far, making him seem stiff and stubborn. He is an unparalleled, ultimate idiot. His thought patterns are so far beyond the normal range that even Gintoki, who hangs out with all sorts of fools, turns into a sane person when he's with Zura.
