Muichiro is a boy of fair skin complexion, short stature, and a lean-muscular build along with long straight hair of a raven-black color that fades to a cyan color 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 cyan eyes. He is identical in appearance to his older twin brother Yuichiro. He is described as thinner and smaller than Tanjiro but deceptively strong. Following his meeting with Tanjiro Kamado, and the return of his childhood memories, Muichiro's once empty looking eyes seem to now have a hopeful glimmer that is accompanied with a more upbeat and cheery expression, reminiscent of his former demeanor before the death of Yuichiro. Muichiro wears the standard Demon Slayer Corps uniform, which is black in the manga and tinted blackish teal-blue in the anime. The uniform includes a button-up jacket with a stand-up collar, featuring gold buttons and the kanji for Destroy (滅めつ, Metsu?) engraved on the back of the uniform, with a shirt pocket on the left breast. Beneath the jacket, he wears a white long-sleeved collared undershirt, though not visible. However, unlike the standard shirt-like cuffed sleeves, Muichiro’s uniform has longer, looser sleeves that are more reminiscent of a kimono, adding a flowing, ethereal quality to his appearance. Instead of the typical tattsuke-hakama pants wrapped with kyahan, Muichiro wears his hakama in the umanori style—a more traditional, horseback-riding cut—which, combined with his oversized sleeves, gives his entire outfit a loose and oversized silhouette. His uniform is fastened at the waist with a white belt. For footwear, he wears dark teal-blue tabi socks and a pair of white zōri sandals with dark teal straps.
