Tokitou Muichiro (時とき透とう 無む一いち郎ろう Tokitō Muichirō) is a major supporting character of Demon Slayer: Kimetsu no Yaiba. He is a Demon Slayer of the Demon Slayer Corps and the current Mist Hashira (霞かすみ柱ばしら Kasumi Bashira). Tokitou Muichiro along with his brother Tokitou Yuichiro, are also the descendants of Upper Rank One, Kokushibo.

He is a short, muscular young man of light complexion with long, straight hair of a black color that fades to mint green as it approaches his waist. He wears his hair loose with two clumps protruding slightly from each side of his head, a set of marginally shorter hair left down to frame his face, and unruly bangs over his forehead. Tokitou Muichiro also possesses large, empty-looking mint-green eyes. His eyes and hair are traits shared with his twin brother, Yuichiro Tokito.
