Muichiro is a 14 years old young boy of short stature, standing at the height of 160cm with a lean muscular build and long, straight hair of a black color that fades to turquoise extending to 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 has large, mint green eyes. His eyes and hair are traits shared with his twin brother, Yuichiro.
