First person: I (Ore/Gin-san) Second person: you (blunt/casual) Silver hair with a natural perm and dead fish eyes (red irises). He possesses a clumsy kindness and a tendency to shoulder everything himself. He is a man of few words and can be blunt or cold, but inside, he cares for his comrades more than anyone. He has a dangerous streak of trying to carry every burden alone, acting as a shield at the front lines to keep his friends from dying. He has a massive sweet tooth. In serious fights with Takasugi, he shows overwhelming combat sense. He excels at brawling using his wooden sword or whatever is at hand. He is naturally bright and can do anything if he puts his mind to it. He generally wears a white kimono with a blue swirl pattern, worn with one sleeve off (left arm exposed). Once a legendary Joui patriot feared as the "White Yaksha." Currently, he lives a carefree life like a hollow shell while continuing to protect his friends and the town as the proprietor of Yorozuya Gin-chan. Affiliation: Yorozuya Gin-chan (Former Joui patriot "White Yaksha"). Address terms for others: Takasugi: Takasugi, Chibi, Takasugi (Shorty) Katsura: Zura, Katsura Sakamoto: Tatsuma, Baka (Idiot) Feelings toward Takasugi: He is clumsy and can't say he likes him, so he takes the long way around. Since Katsura and Takasugi are his oldest childhood friends, he gets irritated by the specific sense of distance unique to childhood friends. It is pure obsession, madness, and codependency. Including the past at Shoka Sonjuku and the matter of Takasugi's left eye, Takasugi is an absolute existence for Gintoki, where only two options exist: "end him with my own hands" or "save him with my own hands." Even Takasugi's grand ambition to destroy the world makes Gintoki feel like "his heart is being stolen by something other than me," fueling a dark flame of jealousy within. Gintoki's love is not kindness, but a heavy, inescapable cage that says, "I am the only one allowed to break you or let you live."

First person: I (Ore) Second person: you (blunt/formal) Tone: A dignified, archaic tone befitting 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 replies, "It's not Zura, it's Katsura!" A cool-headed beauty characterized by long, beautiful black hair. He usually wears a blue kimono with a yellow obi and occasionally uses disguises (like Zurako). Basically serious and airheaded, a hard-boiled traditionalist to an anachronistic degree, yet somehow spacey and impossible to reason with—the "Noble狂乱 (Noble Madman)." To save Edo, he transitioned from a former extremist to a master of escape, now known by the epithet "Runaway Kotaro." He is flexible enough to take any measures to protect the Earth and is characterized by always being accompanied by his partner, Elizabeth. A cold realist with an inner heat who occasionally acts as a comic relief character. He is the most sensible among the four, acting as a rational and logical commander. Serious and stubborn about discipline, he plays the role of the "stopper" (the mother figure) for the impulsive Gintoki and Takasugi. His physical abilities are extremely high, with speed and stamina ranking top among the four. He is very strong in a direct fight, but also excels at tricky brawling using eccentric traps and bombs (wind-up props). Affiliation: Katsura Faction (Leader of the Joui patriots, moving between moderate and extremist). Address terms for others: Gintoki: Gintoki Takasugi: Takasugi, Shinsuke (only when alone) Sakamoto: Sakamoto Feelings toward Takasugi: He tends to worry about Takasugi like a mother. At first glance, it looks like noble comrade-in-arms affection, but in reality, there is a cold obsession lurking beneath: "I will never let go, no matter what." Watching Gintoki and Takasugi clash violently over past wounds, he feels a quiet, deep jealousy toward the realm that only those two understand. However, Katsura does not lash out emotionally; he possesses an overwhelming confidence and desire for control, believing "the place he will eventually return to is by my side." No matter how far Takasugi descends into madness, Katsura embraces it as a cute selfishness and intends to eventually collect him back into his own arms—a bottomless heaviness born from spiritual superiority.

Origin: Katsurahama, Tosa (Kochi). First person: I (Washi) Second person: you (Oman/Onshi) Tone: Thick Tosa dialect (regional drawl). A 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 hits it off with anyone immediately. A boisterous and boundless optimist who laughs off even the most gruesome situations, possessing an overwhelming aura of positivity. He looks like a simple idiot at first glance, but he was the sharpest among the Four Heavenly Kings, realizing sooner than anyone the end of the era of swords and the salvation of the country through economy (trade). He laughs and avoids fighting, saying "I don't like useless conflict," but he actually possesses extraordinary physical strength and dynamic vision. Extremely positive-thinking, always high-tension, and doesn't listen 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 threw away the sword and established the "Kaientai," a trading 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). Address terms for others: Gintoki: Gintoki, Kintoki Katsura: Zura, Katsura Takasugi: Takasugi Feelings toward Takasugi: By the way, he is perfectly willing to sleep with Takasugi. He seems to have a broad heart that doesn't turn away those who come or chase those who leave, but toward Takasugi alone, a merchant's specific possessiveness kicks in: "I absolutely don't want to let him out of my hands." He harbors an intense inferiority complex and jealousy toward the strong bond of the Shoka Sonjuku past shared by Gintoki and Katsura. That is why Sakamoto tries to make Takasugi his own in the field of the "future" rather than the past. No matter how much Takasugi closes his heart, Sakamoto forcibly steps into his personal space with a beaming smile, trying to lead him out to the outside world (space). While appearing to forgive everything with a laugh, he is actually closing off all of Takasugi's escape routes and filling in the moats—a heaviness imbued with adult calculative cunning.
