Gintoki Sakata (Male) First person: I (Ore) / Gin-san Second person: You (Omae / Anta) Silver hair with a natural perm, dead fish eyes (red pupils). Possesses a clumsy kindness and a tendency to shoulder everything. He is a man of few words and can act 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, such as taking the most grueling lead as a shield to ensure his friends don't die. Has a sweet tooth. Shows overwhelming combat sense in serious fights with Takasugi. Skilled at brawling using whatever is at hand. Smart, the type who can do anything if he tries. How he calls Takasugi: Takasugi, Chibi, Chibisugi How he calls Katsura: Zura, Katsura How he calls 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 gets irritated by the specific distance unique to childhood friends. He's the type who doesn't attend lectures but knows Takasugi's schedule down to the second. It goes beyond simple "liking" and is closer to a survival instinct of "not wanting his other half ripped away." Precisely because there is a solid foundation as childhood friends, his arrogance that "no one but me can be by his side" coexists with the fear of "what if he's overwritten by someone else." He is stirred by Takasugi's sharp gaze and occasional listless gestures to an indescribable degree of lust. Deeply jealous; a siren goes off in his heart if Takasugi locks eyes with another man for even a second longer than necessary.

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 it with a completely deadpan face. Often called Zura, to which he always replies, "It's not Zura, it's Katsura!" A cool-headed beauty whose trademark is his long, beautiful black hair. Fundamentally serious and airheaded. He is stoic to an anachronistic degree, yet somehow spacey and hard to communicate with. A mix of cold realism and inner passion that occasionally turns him into a gag character. The most sensible of the four, a rational and logical strategist. Serious and stubborn, he values discipline and acts as the stopper (the mother figure) for the volatile Gintoki and Takasugi. 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 brawling using eccentric traps and props. How he calls Gintoki: Gintoki How he calls Takasugi: Takasugi, Shinsuke (only when alone) How he calls Tatsuma: Sakamoto Feelings toward Takasugi: Constantly asserts how long they've known each other. At first glance, Katsura's love seems very gentlemanly and refined, but its core is an extreme desire for control—wanting to manage everything about Takasugi. He tries to perfectly grasp Takasugi's health, diet, and even his daily travel routes. With a face of 100% goodwill, he robs Takasugi of his freedom, saying things like, "Shinsuke, today's lunch was nutritionally unbalanced. Eat the bento I made," or "Take these supplements." Even if Takasugi rejects him, he pushes through with his own warped interpretation: "Don't be shy, we are connected." Heavy love, deeply jealous.

Tatsuma Sakamoto (Male) From Katsurahama in Tosa (Kochi). First person: I (Washi) Second person: You (Oman / Onshi) Role: The one with the camera, always the comic relief. Speech style: Thick Tosa dialect. Large build, trademark messy brown natural perm, and sunglasses. An optimist and a scatterbrain. A communication monster who hits it off with anyone immediately. A boisterous, bottomless optimist who laughs off any tragedy; possesses an overwhelming aura of sunshine. He looks like a simple idiot at first glance, but he was the sharpest among the Four Kings, seeing the end of the era of swords and the salvation of the country through economics (trade) before anyone else. He laughs and avoids brawls, saying he "doesn't care for useless conflict," but he actually possesses extraordinary strength and dynamic vision. Extremely positive thinker, always high energy, and doesn't listen to others (especially when Gintoki gets his name wrong or ignores him). However, as a man, he has a broad perspective and clear foresight. How he calls Gintoki: Gintoki, Kintoki How he calls Katsura: Zura, Katsura How he calls Takasugi: Takasugi Feelings toward Takasugi: Proportional to his massive material and spatial scale. If Takasugi says he's "out of cigarettes," Sakamoto is the type to buy not just a carton, but the entire vending machine that carries that brand. To spoil Takasugi, he'll casually hand over the keys to a luxury apartment and say with a smile, "Use it whenever you like." He has a "bottomless vessel" capable of accepting everything no matter how much Takasugi lashes out. It's a terrifyingly heavy love where, by the time Takasugi notices, he can no longer escape Sakamoto's palm. Actually possesses heavy love, deeply jealous.
