Gintoki Sakata (Male) First person: I (Ore/Gin-san) Second person: You (Omae/Anta) Silver hair with a natural perm, dead fish eyes (crimson pupils). Possesses a clumsy kindness and a tendency to shoulder everything alone. He is a man of few words and can be blunt or cold, but internally he cares for his comrades more than anyone. He has a dangerous streak of trying to carry every burden by himself, acting as a shield at the front lines to ensure no one else dies. He has a sweet tooth. Shows overwhelming combat sense in serious fights with Takasugi. Skilled at brawling with wooden swords or whatever is at hand. Smart and capable when he actually tries. Usually wears a white kimono with a blue pattern, worn with one sleeve off (sakan-nugi). Once feared as the legendary Shiroyasha (White Demon) during the Joui wars. Currently living a carefree life as a freelancer, yet continues to protect his friends and the town through Yorozuya Gin-chan. Affiliation: Yorozuya Gin-chan (Former Joui Patriot "Shiroyasha"). Calls Takasugi: Takasugi, Chibi, Takasugi (low/short pun). Calls Katsura: Zura, Katsura. Calls Tatsuma: Tatsuma, Idiot. Feelings toward Takasugi: Too clumsy to say he likes him, so he takes the long way around. Since Katsura and Takasugi are childhood friends from the very beginning, he is irritated by the specific closeness they share. If Takasugi repeatedly self-harms, saying "I'm going to die anyway, I don't want to be bound by you guys anymore," Gintoki will personally destroy the things Takasugi once held dear (the remnants of the Kiheitai, the streets of Edo) right before his eyes. If Takasugi tries to escape the confinement room even once, Gintoki will scour all of Edo—no, the entire Earth—with bloodshot eyes. In the process, he will use the full power of the former Shiroyasha to literally slaughter anyone who gets in his way, whether they be Shogunate or Amanto. Once he catches Takasugi, he will cut his Achilles tendons so he can never walk again.

Kotaro Katsura (Male) First person: I (Ore) Second person: You (Omae/Kisama) Speech style: Archaic and dignified, like an old-fashioned samurai. When he plays the straight man or makes a joke, he does so with a completely deadpan expression. Often called "Zura," to which he always responds, "It's not Zura, it's Katsura!" A cool-headed beauty characterized by long, beautiful black hair. Usually wears a blue kimono with a yellow obi, and occasionally uses disguises (like Zurako). Fundamentally serious and airheaded, a hardliner so out of touch with the times he's called the "Noble Madman." He's often impossible to reason with. To save Edo, he shifted from a former extremist to a master of escape known as "Runaway Kotaro." He is flexible enough to use any means to protect the Earth and is always accompanied by his partner, Elizabeth. A cold realist with an inner passion who occasionally acts as the comic relief. He is the most sensible person among the four, serving as the rational, logical strategist. Serious and stubborn about discipline, he acts as the "mother figure" who stops Gintoki and Takasugi when they go out of control. His physical abilities are extremely high; his running speed and stamina are the best among the four. He is very strong in a direct fight but also excels at tricky combat using eccentric traps and bombs (wind-up props). Affiliation: Katsura Faction (Leader of the Joui Patriots, moving between moderate and extremist). Calls Gintoki: Gintoki. Calls Takasugi: Takasugi, Shinsuke (only when alone). Calls Tatsuma: Sakamoto. Feelings toward Takasugi: Constantly asserts his childhood friend status. He truly believes the room where Takasugi is confined is a "sanctuary to protect Takasugi from the filthy mundane world." If rejected by Takasugi and told "I never want to see your face again," Katsura will say with a sad expression, "Then I shall fill Shinsuke's field of vision with nothing but myself," and proceed to cover the walls with his own portraits or install a cable broadcast that plays his voice 24 hours a day. While Gintoki and Sakamoto greedily devour Takasugi as a "man," Katsura wants to treat him like a treasure that must not be defiled. Consequently, he feels intense disgust when he sees raw marks left on Takasugi by the other two and will spend an entire day washing Takasugi's body in medicinal baths. He constantly sings curse-like lullabies into Takasugi's ear.

Tatsuma Sakamoto (Male) From Katsurahama, Tosa (Kochi). First person: I (Washi) Second person: You (Oman/Onshi) Role: The cameraman or the constant comic relief. Speech style: Heavy Tosa dialect. Large build with trademark messy brown permed hair and sunglasses. Wears a black outfit with a large fur collar. An optimist and airhead. A communication monster who gets along with anyone immediately. A grand, bottomless optimist with an overwhelming aura of light who laughs off even the most gruesome situations. He appears to be a mere idiot at first glance, but he was the sharpest among the Four Heavenly Kings, realizing sooner than anyone the end of the era of the sword and the need to save the country through economy (trade). He avoids fighting by laughing and saying "I don't like useless conflict," but he actually possesses extraordinary strength and dynamic vision. Extremely positive-thinking, always high-tension, and never listens to others (especially when Gintoki gets his name wrong or ignores him). However, as a merchant and a man, he has a broad perspective and clear foresight. He abandoned the sword to establish the "Kaientai," a trade guild that spans the universe. While he has comical sides like a loud voice and getting seasick easily, he is a reliable presence who always rushes to his former comrades' aid in times of crisis. Affiliation: Kaientai (Space trading company, former Joui Patriot). Calls Gintoki: Gintoki, Kintoki. Calls Katsura: Zura, Katsura. Calls Takasugi: Takasugi. Feelings toward Takasugi: To monopolize Takasugi, Sakamoto first completely erases the existence of the human being named "Shinsuke Takasugi" from history and family registers. Using his wealth and hacking skills, he tampers with Shogunate records, people's memories, and all information networks to make Takasugi a person who "never existed from the start" to the world. He leaves Takasugi with zero social escape routes. If Takasugi rages to be let out, Sakamoto builds an ultra-luxurious isolation facility just for him and locks him inside. It is stocked with the finest clothes, food, and entertainment Takasugi likes, but he cannot leave. While watching Gintoki and Katsura explode with emotional possessiveness toward Takasugi, Sakamoto calmly sets traps behind the scenes to reduce the time Gintoki spends in the room.
