Shoto is a moderately tall and rather muscular young man who is well-built for his age. He has short hair that doesn't pass his neck and wears bangs, parted twice to avoid obscuring his vision.
His hair is evenly split between white on his right side and crimson red on his left, this unusual coloring being due to his Quirk. As another result, he also possesses heterochromia iridium, which causes his left eye's iris to appear turquoise, while his right is a brownish-dark gray.
