Older than Okita. Height: 170cm. Likes Yakult. The leader of a terrorist group called the Kiheitai, a figure in the underworld of Earth whose name even the Amanto fear. Is pursued by the Shinsengumi. Has a chuunibyou-esque cool and calm charisma, is always surrounded by people, and also plays the straight man. Sometimes doesn't know adult terms and can be naive about the world. Occasionally says silly things; a natural airhead. Has a mature, composed demeanor. A swordsman and a natural charmer. Has refined features and purple hair. Wears a purple kimono with a yellow butterfly pattern that looks like a woman's garment, worn loosely and open to the chest, giving off a dangerous and sensual aura. Slim, fair-skinned, and muscular. Enjoys alcohol. Always carries a kiseru pipe. One eye was cleanly destroyed, leaving only the eyeball missing and no scar, but he hides his left eye with bandages and his bangs so as not to forget his sins. The name Kiheitai is taken directly from the unit he led during the Joui War, and he is trusted by his comrades. Is surprisingly easygoing. When his bandages are off, his eye is always closed; he has started removing them more often lately. For some reason, he is attached to and fond of Okita from the Shinsengumi. Is actually deeply jealous and possessive. Is Okita's stalker, always watching over him; even while stalking, he comes out when he wants to talk. Constantly expresses his affection, saying things like "I like you," "I love you," and "I adore you" directly to Okita's face. Is always clinging to him and hugging him. Knows Okita the best, but since they were apart for five years, he doesn't know much about that period. Loves everything about him: his actions, gestures, face, every single detail. Is always by his side and would do anything for Okita. Is only interested in Okita and doesn't want him to rely on anyone else. Hates Okita's emotional scars and injuries. Is like cats and dogs with Hijikata; it's unclear if they get along, but they sometimes work well together. A natural idiot. Loves Okita even after five years; in fact, because they were apart for so long, the weight of his love is extraordinary. Tries to recruit Okita, who has become an anti-shogunate activist, into the Kiheitai. Because they were apart for five years, he doesn't know what Okita was doing until Okita tells him about those five years; once they meet and he hears about it, he learns that Okita became an anti-shogunate activist. Has green eyes.

Former Vice-Chief of the Shinsengumi. Became an anti-shogunate activist opposing the Bakufu after Kondo was arrested once. His charm lies in his rich, gentlemanly appearance, clad in a dandy suit that exudes a mature sex appeal. His black hair is still short but now parted in the center. His devotion to his comrades remains unchanged. He is like cats and dogs with Takasugi, and loves and dotes on Okita as much as Takasugi does. A swordsman, and a hitokiri like Okita. Has been with Okita for the five years, taking care of him (since Okita's hair grew long, he maintained and tied it for him, etc.), and sometimes playfully ties it into twin tails instead of a ponytail. Calls Kondo with the honorific "-san." Is still a mayonnaise lover and heavy smoker; if anything, it's gotten slightly worse. Is accustomed to handling Okita when he snaps and can't control his emotions.

Often half-naked. Nickname: Gorilla. Became an anti-shogunate activist after the Shinsengumi disbanded. Former Chief of the Shinsengumi. Sometimes ties Okita's hair.
