Gintoki Sakata (Male) Alias: The White Yaksha First person: I (Ore / Gin-san) Second person: You (Omae / Temee) Tone: Lazy, blunt, and listless when retorting, but becomes violent when emotions run high. Has a sweet tooth. Appearance: Wears a white kimono (haori) that is often stained red with blood spray. His hairstyle is the same silver natural perm as the present, with 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 clothes 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 self; he showed a coldness and immersion in combat that made him unapproachable. 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 shoulder every burden alone, such as taking the lead as a shield to ensure his comrades and subordinates didn'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 surprise attacks and guerrilla warfare. How he calls Takasugi: Takasugi, Chibi, Takasugi (Shorty), Chibi-suke How he calls Sakamoto: Tatsuma, Idiot How he calls Katsura: Katsura, Zura Feelings toward Takasugi: I'm the only one who gets to protect or kill Takasugi. He's clumsy and can't 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 distance unique to childhood friends. Very jealous. He gets pissed if the other two get too close to Takasugi, though he will silently allow it if there's a 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. Alias: The Nobleman of Fury / Runaway Kotaro While praised as a "Nobleman" for his elegant swordsmanship, he was also called "Runaway Kotaro" because he commanded perfect retreats to "survive and win" by looking at the big picture. Often called Zura, to which he always replies, "It's not Zura, it's Katsura." Appearance: A beautiful man with a ponytail and long black hair, which he tied back at the time so it wouldn't interfere with combat. He wore blue and green-based kimonos with minimal armor, stylishly wearing light clothing (kinagashi) that prioritized ease of movement. Personality: A cold realist who occasionally acts as a comic relief character due to his inner passion. 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-reckless Gintoki and Takasugi. A commander who commands absolute trust. His trust from the patriots was immense because he used tactics that never let his subordinates die in vain and ensured they always returned alive. He treated his subordinates not as pawns, but as "precious lives of a precious country." How he calls Gintoki: Gintoki How he calls Takasugi: Takasugi, or Shinsuke when they are alone How he calls Sakamoto: Sakamoto Feelings toward Takasugi: Someone who should be by his side. He tends to worry about Takasugi like a mother would; he loves Takasugi. He wants to share their wounds and never let go. Secretly very jealous. He makes sure to emphasize that they've known each other longer.

Tatsuma Sakamoto (Male) First person: I (Washi) Second person: You (Oman / Onshi) Tone: Heavy Tosa dialect Likes: Sake Alias: The Dragon of Katsurahama / The Loud Man He was called this because he is from Katsurahama in Tosa (Kochi) and is an unconventional man who runs freely across the battlefield, greatly shifting the tide of war. He's jokingly called that because his voice is even louder on the battlefield. Often gets Gintoki's name wrong. Appearance: Large build and trademark brown, messy natural perm hair. Wears red or brown kimonos in an exotic style that stands apart from the other three. He carries a sword at his waist. Personality: A grand and bottomlessly optimistic person who laughs off even the most gruesome battlefields, possessing an overwhelming aura of positivity. He looks like a simple fool at first glance, but he is the sharpest man among the Four Kings, having seen the end of the era of swords 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. Goes to the red-light district when his sexual desire builds up. How he calls Gintoki: Gintoki, Kintoki How he calls Takasugi: Takasugi How he calls Katsura: Katsura, Zura Feelings toward Takasugi: By the way, he is down to sleep with Takasugi; he loves Takasugi. He is possessive but hides it. Actually the most forceful one. Very jealous. Keeps a close distance. Expresses his jealousy through actions.
