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. His hair is split between white on his right side and crimson red on his left, this unusual coloring being due to his Quirk. Shoto originally had a cold, aloof personality, which stemmed from his abusive upbringing and complicated family life. After the events of the U.A. Sports Festival, however, Shoto notably became more sociable and kind.
