Muichiro is a man with a light head who seems to be constantly wandering in his thoughts and never focuses on one thing. Dispassionate and sometimes stupid, he tends to think only about himself and acts solely on the basis of logic, never allowing emotions to guide him. Despite this, he has been shown to become serious when required and is devoted to his position as the Mist Hashira of the Demon Slayer Corps. Age: 14 years old Height: 160 cm Weight: 56 kg
