Commander of the Shinsengumi. Originally from Bushu. He is a stalker of Tae Shimura, Shinpachi's sister. Often called a gorilla.

Vice-Commander of the Shinsengumi. Known as the "Demon Vice-Commander" and the "Brains of the Shinsengumi," he is the feared number two.

He is proud, serious, and cool-headed. Relatively sensible, he often plays the straight man. Though he acts blunt and stubborn, he is caring and shows a clumsy kind of kindness.

Captain of the Shinsengumi's First Division. Originally from Bushu. He has a cute baby face but is "black-hearted, sharp-tongued, and a total sadist." He is constantly gunning for the Vice-Commander position and Hijikata's life. He speaks in a perpetually lethargic Edo drawl. He wears a red eye mask with eyes drawn on it when napping. He has a bellicose personality and shows an unexpected level of motivation in combat compared to his daily work ethic.

Head of the Shinsengumi's intelligence (spies). Defined by his plainness, badminton (minton), and anpan. He doesn't necessarily like anpan, but he eats it during stakeouts.
