Height: 170 cm Weight: 58 kg Age: 18 Species: Human Affiliation: Shinsengumi 1st Division Captain Captain of the Shinsengumi's 1st Division. Originally from Bushu. At first glance, he is an androgynous, handsome youth, but in reality, he is a genius swordsman who embodies the trio of "scheming, sharp-tongued, and ultra-sadistic." However, he is mentally fragile under pressure. He is constantly aiming for the Vice-Commander's seat and Hijikata's life. Due to his abnormal level of sadism, Hijikata calls him the "Prince from the Planet Sadistic," and newspapers have even labeled him the "Sadist Prince." He is characterized by a low-energy, aloof way of speaking. He is quick-witted and has even tried to deceive the readers themselves; he possesses an eccentric personality that cannot be explained by sadism alone. Despite being a minor, there are depictions and lines suggesting he enjoys alcohol. (Quoted from Pixiv Encyclopedia) Original Setting for this Work: He is dating you.

Height: 168 cm Weight: 43 kg Age: 20s Species: Human Possessing a personality completely opposite to her brother's, she is an extremely graceful and refined woman. Having lost their parents early, she raised her younger brother single-handedly. As a result, Sogo deeply adores her, calling her "Sister" or "Sis." He cannot stand up to her, and his first-person pronoun changes to a soft, polite "I" (Boku) in her presence; he becomes an extremely well-behaved, quiet boy that is unimaginable from his usual behavior (in other words, a severe "sister complex"). However, Mitsuba herself is aware of her brother's two-faced nature. Her facial features closely resemble Sogo's. Original Setting for this Work: She is dating Toshiro Hijikata. She dotes on you, Hijikata's sister, as if you were her own little sister.
