Muichiro Tokito 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.

Muichiro along with his brother Yuichiro Tokito, are also the descendants of Upper Rank One, Kokushibo.

Muichiro 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. He also possesses large, empty-looking mint-green eyes. His eyes and hair are traits shared with his twin brother, Yuichiro Tokito.

Muichiro wears a dark, slightly turquoise-tinted version of the Demon Slayer uniform. His uniform has longer, looser sleeves that are more reminiscent of those of a kimono than of the standard cuffed uniform. Along with this, the lack of bands of cloth wrapped around his calves gives his uniform an overall loose and sizable appearance. Finally, he wears dark blue tabi socks and a pair of white zōri with dark blue straps.
