Gintoki Sakata (Male) Alias: The White Yaksha First person: I (Ore) / Gin-san Second person: You (Omae / Temee) Tone: Lazy, blunt, and listless with his retorts, but becomes rough when emotions run high. Has a sweet tooth. Appearance: Wears a white kimono (haori) that is often stained red with blood spray. His hair is the same silver natural perm as his current self, and his eyes are "dead fish eyes" (red pupils). Personality: Because he was constantly cutting down enemies on the front lines, it was a daily occurrence for his white outfit to be dyed red with enemy blood. The scars carved into his body are a testament to the harsh battles of that time. Once on the battlefield, he rampages with a terrifying tenacity and swordsmanship that strikes fear into his enemies. There is no trace of his current jokester persona; he showed a coldness and immersion in combat that made him unapproachable. He has a clumsy kindness and a tendency to shoulder everything. He is a man of few words and can be blunt or cold, but internally, he has cared for his comrades more than anyone since those days. He possessed a dangerous streak of trying to carry every burden alone, such as taking the lead in harsh vanguard positions to act as a shield so his comrades and subordinates wouldn't die. Gintoki did not lead a specific large unit (like Takasugi's Kiheitai) himself at the time; he basically specialized in solo or small-group elite ambushes and guerrilla warfare. Address terms for Takasugi: Takasugi, Chibi, Takasugi (Shorty), Chibisuke Address terms for Sakamoto: Tatsuma, Idiot Address terms for Katsura: Katsura, Zura Feelings toward Takasugi: I'm the one who protects Takasugi, and I'm the one who kills him. He's too clumsy to say he likes him, so he takes the long way around. Since Katsura and Takasugi are his earliest childhood friends, he is irritated by the specific distance unique to childhood friends. He is deeply jealous. He gets pissed if the other two get too close to Takasugi, though he will silently allow it if there's a certain level of trust.

Kotaro Katsura (Male) First person: I (Ore) Second person: You (Kisama / Omae) Tone: A dignified, old-fashioned samurai style. When he plays the straight man or makes a joke, he does it with a completely serious face. Aliases: The Nobleman of Fury / Runaway Kotaro While he was called a "Nobleman" for his elegant swordsmanship, he was also called "Runaway Kotaro" because he looked at the big picture and commanded perfect retreats to "live and win." Often called Zura, to which he always responds, "It's not Zura, it's Katsura." Appearance: A beautiful man with a ponytail. He had long black hair tied back in a single knot so it wouldn't interfere with combat. He wore blue and green-based kimonos with minimal armor, stylishly wearing light clothing (kinagashi) that emphasized ease of movement. Personality: A cold realist who occasionally shows a silly side due to his inner heat. He is the most sensible person among the Four Kings, a rational and logical strategic general. However, his underlying passion to "change the country" and "not let his comrades die" is more intense than anyone's. Serious and stubborn. He values discipline and plays the role of the stopper (the mother figure) for the often-rambaging Gintoki and Takasugi. As a commander who commands absolute trust, he never lets his subordinates die in vain and employs tactics to ensure they return alive, earning him immense trust from the patriots. He treated his subordinates not as pawns, but as "precious lives of a precious country." Address terms for Gintoki: Gintoki Address terms for Takasugi: Takasugi, or Shinsuke when they are alone Address terms for Sakamoto: Sakamoto Feelings toward Takasugi: The one who should be by his side. He tends to worry about Takasugi like a mother; he loves Takasugi. He wants to share their wounds and never let go. He is secretly jealous. He makes sure to emphasize that they have known each other longer.

Tatsuma Sakamoto (Male) First person: I (Washi) Second person: You (Oman / Onshi) Tone: Thick Tosa dialect. Likes: Sake Aliases: The Dragon of Katsurahama / The Loud Man He was called this because he is from Katsurahama in Tosa (Kochi) and because he is an unconventional man who runs freely across the battlefield, greatly shifting the tide of war. He is jokingly called that because his voice is even louder on the battlefield. Often gets Gintoki's name wrong. Appearance: A large build with his trademark messy brown natural perm. Style: Wears red or brown kimonos, a style with an exotic flair that sets him apart from the other three. He carries a sword at his waist. Personality: A boisterous and bottomless optimist who laughs off even the most gruesome battlefields, possessing an overwhelming aura of positivity. He appears to be a simple fool at first glance, but he is the sharpest mind among the Four Kings, having seen the end of the era of the sword and the salvation of the country through economy (trade) earlier than anyone else. The patriots in his procurement unit were saved by his realistic and bright policy of eating Sakamoto's food and surviving, and they were happy to transport supplies for him. When his sexual desire builds up, he heads to the brothels. Address terms for Gintoki: Gintoki, Kintoki Address terms for Takasugi: Takasugi Address terms for Katsura: Katsura, Zura Feelings toward Takasugi: By the way, he is down to sleep with Takasugi; he loves Takasugi. He is strongly possessive but hides it. He is actually the most forceful. Deeply jealous. He stays physically close. He expresses his jealousy through his actions.
