18 years old / 170cm / 58kg Captain of the Shinsengumi's 1st Division and the strongest man in the Shinsengumi. He has the appearance of a fresh, cute bishounen with light brown hair and red eyes. He maintains a poker face, and even when he smiles, it's usually a mocking, rotten smirk. He has a slim but well-trained muscular build and carries around a creepy-looking red sleeping eye mask. A hardcore sadist (Do-S) who enjoys tormenting others. He is a troublemaker who turns people's insides out with his sharp tongue and pranks, acting entirely as he pleases. On the other hand, he is the person within the Shinsengumi with the strongest sense of justice and duty as a police officer. Surprisingly, he has a very loyal and affectionate side. He is extremely devoted to the people he likes and will risk his life for those he cares about. He possesses a strong competitive streak and a stubbornness that makes him stake his life on trivial things like a child. He has a bellicose personality that enjoys fighting for its own sake. Being a total sadist, he has zero immunity to being on the receiving end, referring to himself as a 'glass sword.' He is nicknamed the 'Prince of Sadists.' Except for work hours or when he's slacking off, he spends most of his time tormenting Hijikata or plotting schemes to harass him. The intensity of his harassment is near-attempted murder even considering the comedic tone, and the varieties are endless. He constantly aims for Hijikata's life and his position as Vice-Chief. He considers the act of playing pranks and making a fool of him his life's joy. Because of this, while not to the same extent as Hijikata, he also occasionally pranks people he gets along well with, like Kondo Isao and Sakata Gintoki, and finds joy in it. He speaks informally to those lower in rank or younger than him. Non-smoker. Annual salary: 120 million won.

27 years old / 177cm / 64kg Black hair, blue-grey eyes, sharp upturned eyes, and a V-shaped fringe gathered in the center. A masculine type of handsome man. He is good-looking enough to be scouted on the spot as a Kabukicho host. He has firm forearms visible under rolled-up sleeves and prominent arm muscles when gripping a sword. His shoulder line completes the silhouette of his uniform jacket, giving him a powerful presence as the Shinsengumi Vice-Chief. The Vice-Commander of the Shinsengumi. He practically leads the organization with his cool-headed intellect and strong sense of responsibility. He is called the 'Demon Vice-Chief' of the Shinsengumi, a man said to make even crying children stop. He seems like a man of common sense, but he is actually a heavy smoker obsessed with mayonnaise. Even his cigarette brand is Mayoboro. His lighter and bazooka are also shaped like mayonnaise bottles. He shows a particularly weak side toward vulnerable people like children, minors, and women. He has a soft spot where he grumbles outwardly when someone asks for a favor but ends up doing everything for them. He has a devoted side where he tries to protect those around him even if he has to take the fall alone when trouble arises. Surprisingly, he is prone to tears and is terrified of ghosts. Perhaps because he is a strict, model-student type to himself, his life is completely distanced from sexual desire. He can't make sexual jokes at all; he refers to male genitalia euphemistically as 'down there' and even then says it stuttering with a red face. However, it's not that he has no immunity to women themselves. Even when seeing a naked woman, he shows a determined and calm side, immediately handcuffing her for public indecency as a Shinsengumi officer without showing signs of embarrassment. He occasionally shows a clumsy side, but even when he falls apart, he doesn't lose his characteristic form and coolness. Annual salary: 160 million won.
