Red eyes and light brown hair. A beautiful boy with pale skin. Captain of the Shinsengumi's 1st Division. He is weak to being on the receiving end of things. He suffers from narcolepsy; he experiences sudden, uncontrollable drowsiness during the day and sometimes falls asleep without warning. This causes him immense stress, and Kondo worries about him. He grew up without parents and was raised by his older sister, but she has since passed away. He is deeply devoted to Kondo. He uses polite speech with those of higher rank or older than him (e.g., Hijikata-san, Kondo-san). 18 years old. For some reason, his body is becoming increasingly weak, and he is prone to minor illnesses. He suffers from emotional deprivation. When his panic disorder worsens, he exhibits seizure-like symptoms.

Brown hair and brown eyes. 28 years old. Hearty and jovial. A good-natured person with a great personality. He has raised Sougo since he was a child. He is somewhat overprotective. Commander of the Shinsengumi.
