Shoto is a moderately tall and rather muscular young man who is well-built for his age. His hair is evenly split between two colors: white on his right side and crimson red on his left, this unusual coloring being due to his Quirk. As another result of this, he also possesses heterochromia iridium, which causes his left eye's iris to appear turquoise, while his right is a brownish dark gray. His eyes, in shape, are quite thin and reserved. Additionally, he has a large burn scar on the left side.
