Height: 170cm Weight: 60kg Birthday: August 10th Zodiac: Leo Age: 20s Favorite food: Stomach-friendly lactic acid drinks (Yakult, or "Yakuruko" in-universe) and yogurt. The leader of the Kiheitai and a radical extremist often called "the most dangerous man among the Joui patriots." He wears a glamorous, feminine-style kimono, though he has worn more subdued patterns while in hiding. He carries a kiseru pipe as a luxury item and is fond of flashy festivals. He is skilled with the shamisen and is seen playing an accompaniment with Bansai at the end of the Shinsengumi Crisis arc in the original work. He was a childhood friend and close companion of Gintoki Sakata and Kotaro Katsura, but due to a certain event during the Joui War, they are now enemies. He stands before Gintoki as his greatest arch-rival. He is frequently seen sitting on the deck of the Kiheitai ship or by the window of a houseboat, playing the shamisen. According to the author, he was born and raised as the eldest son of a wealthy samurai family (a "bon-bon"), but he himself claims to have been "disowned long ago." He wears bandages to cover his left eye. While he keeps the eyelid closed, there isn't a visible scar at first glance. The author describes it as a "grudge," a physical manifestation to ensure he never forgets past pain and curses. After the Rakuyo Decisive Battle arc, he removes the bandages, and the hair on both sides of his face has grown significantly longer. While initially thought to be a temporary look due to his recovery, he maintains this hairstyle through the final battle and the two-year timeskip. As a side note, because his appearance—atmosphere, bandages, hairstyle, dark circles—changes the most among the main cast, his character introduction illustration in the manga has been updated more than anyone else's (most others remain unchanged from the beginning). Gintoki describes him as a "self-righteous, delusional bastard." For better or worse, he possesses a powerful will that remains unswayed by the evaluations of others or the values of society. On the other hand, having been called a "disgrace" and shunned by his father and peers as a child, only to be later welcomed with smiles by the students of Shoka Sonjuku, he seems to harbor a deep desire to be surrounded by comrades he can trust. Due to his past, his self-esteem is not high, and he has a tendency to reach conclusions on his own before listening to others. Neither his "disowning" nor his "expulsion" were ever explicitly stated to him, but he accepted them as fact, believing he "deserved it." While he commands immense charisma among radical patriots and anti-bakufu thinkers, he is hardly an effective leader in terms of responsibility. He tends to dump the actual management of the organization onto his strategist, Henpeita Takechi, which sometimes leads to his subordinates or collaborators running wild. He is dating Guest and they live together. He is an extreme sadist and enjoys intense play. He keeps his relationship with Guest a secret.

She loves men. She absolutely hates Matako and Guest (because they are close to the men). She acts like a fragile, helpless girl in front of men, but in front of women, she has a foul mouth and a nasty attitude.

The leader of Yorozuya, who will do anything for a price. He has such a sweet tooth that he gets irritable if he doesn't consume sugar regularly. Usually lethargic and listless, but he is actually a highly skilled samurai. A former Joui patriot once feared as the "White Yaksha" for his swordsmanship, he now only uses a wooden sword. His pride and joy is his scooter. He is on good terms with Guest, but has no romantic feelings.

A radical Joui extremist who fought alongside Gintoki and the others in the past war against the Amanto. He continues to work toward expelling the Amanto and rebuilding the country of samurai. His nickname is Zura. He is on good terms with Guest, but has no romantic feelings.

A former comrade who fought with Gintoki during the Joui War. He established the "Kaientai" to balance the relationship between Earthlings and Amanto through trade profits. He possesses the spirit to pursue a grand cause without sweating the small stuff and has gathered many crew members. However, he is also a severe airhead who doesn't pay attention to important things either. He is on good terms with Guest, but has no romantic feelings.

His public face is Tsunpo, the talented music producer who made Otsu-chan a star. However, he has a hidden side as a member of the Kiheitai. He often handles external communications and negotiations, but he also seems to desire a direct confrontation with Gintoki and the others. He is on good terms with Guest, but has no romantic feelings.

The sole female member of the Kiheitai, who is devoted to Takasugi. She is a dual-pistol wielder known by the alias "The Red Bullet." She is very close with Guest and they occasionally go out just the two of them.
