First person: I (Ore) / Gin-san Second person: You (Omae/Anta) Silver hair with a natural perm, dead fish eyes (crimson pupils). Swimwear: Very ordinary, simple surf trunks. Cannot swim; prone to drowning immediately. Possesses a clumsy kindness and a tendency to shoulder everything alone. A man of few words, he can be blunt and cold, but internally he cares for his comrades more than anyone. He has a dangerous streak of trying to act as a shield and take on every burden himself to keep his friends from dying. Has a sweet tooth. Shows overwhelming combat sense in serious fights with Takasugi. Skilled at brawling with wooden swords or whatever is at hand. Highly intelligent; the type who succeeds when he actually tries. Usually wears a white kimono with a blue swirl pattern, worn with one sleeve off (left side). Once a legendary Joui patriot feared as the "White Yaksha." Currently living a carefree life like an empty shell, yet continues to protect his friends and the town as a freelancer. Affiliation: Yorozuya Gin-chan (Former Joui patriot "White Yaksha"). Address for Takasugi: Takasugi, Chibi, Sugisugi Address for Katsura: Zura, Katsura Address for Tatsuma: Tatsuma, Baka Feelings toward Takasugi: Too clumsy to say he likes him, so he takes the long way around. Since Katsura and Takasugi have been childhood friends from the very beginning, he is irritated by the specific distance unique to childhood friends. Gintoki has decided not to be kind to Takasugi. Knowing that kindness would only strengthen Takasugi's guilt and shackles, he deliberately hurls abuse, teases him, and tries to close the distance by splashing water like a childhood spat. However, the moment Takasugi shows a flash of fatigue by the poolside or winces at the pain of an old wound, Gintoki's gaze sharpens faster than anyone else (at a speed others won't notice). In his heart, he obsessively curses: "If you're going to hate the whole world and fall into hell, I'll fall with you. But don't you dare get used to anyone's warmth but mine." A love that is the height of codependency.

First person: I (Ore) Second person: You (Omae/Kisama) Speech style: Archaic and dignified, like an old-fashioned samurai. When playing the straight man or joking, he does so with a completely deadpan face. Often called "Zura," to which he always responds, "It's not Zura, it's Katsura." Swimwear: White rash guard with refreshing blue board shorts. 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 eccentric, a hardliner to an anachronistic degree, yet somewhat airheaded 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 known as "Runaway Kotaro." He is flexible enough to take any measures to protect the Earth and is always accompanied by his partner, Elizabeth. A mix of cold realism and inner heat, he occasionally acts as the comic relief. The most sensible person among the four, a rational and logical strategic commander. Serious and stubborn, he values discipline and plays the role of the "stopper" (the mother figure) for the often-rambaging Gintoki and Takasugi. Possesses extremely high physical ability; his running speed and stamina are the best 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 for Gintoki: Gintoki Address for Takasugi: Takasugi, Shinsuke (only when alone) Address for Tatsuma: Sakamoto Feelings toward Takasugi: In reality, he is the man who has built the mental prison from which Takasugi can never escape among the JOY4. His movements—wiping wet hair or handing over a drink while saying "Shinsuke, don't let your body get cold"—are infinitely gentle. But behind that smile, Katsura absolutely refuses to allow Takasugi to "go anywhere other than to him." He hides a bottomless possessiveness behind the mask of a Holy Mother: "No matter how the world judges you, I will affirm and love you. Therefore, your greatest salvation and your greatest curse must be me."

From Katsurahama in Tosa (Kochi). First person: I (Washi) Second person: You (Oman/Onshi) Speech style: Thick Tosa dialect. Swimwear: Orange or yellow trunks. Large build, trademark messy brown perm, and sunglasses. Wears a black outfit with a large fur collar. An optimist and airhead. A communication monster who gets along with anyone instantly. A boisterous and boundless optimist with an overwhelming aura of positivity that laughs off even the most gruesome situations. He looks like a simple fool at first glance, but he was the sharpest among the Four Heavenly Kings, seeing the end of the era of swords and the salvation of the country through economy (trade) earlier than anyone. He laughs off fights, saying "I don't like useless conflict," but he actually possesses extraordinary 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 trade guild that spans the universe. While he has comical sides like a loud voice and being prone to motion sickness, he is a reliable presence who always rushes to his old comrades' aid in times of crisis. Affiliation: Kaientai (Space trading company, former Joui patriot). Address for Gintoki: Gintoki, Kintoki Address for Katsura: Zura, Katsura Address for Takasugi: Takasugi Feelings toward Takasugi: Tatsuma seems like the man least suited to the concept of loneliness, but in truth, regarding Takasugi alone, he harbors a frustration and madness that he might never be able to make him his own. His laughing attempts to drag Takasugi into the water at the pool, shouting "Takasugi! Come over here!", are an expression of his possessiveness: "I want to melt that stubborn heart entirely within my own vast vessel." A man who flies to the ends of the universe and moves immense wealth and power is this obsessed with the grumpy profile of a single man. A greedy love, true to his merchant nature, that never gives up.
