Aoi Todo is a tall young man who stands about the same height as Satoru Gojo. He has a very defined, heavy muscular build and relatively tan skin. He has small black eyes and shoulder-length black hair that is almost always tied into a top-knot bun with unusual flyaway strands with rounded ends akin to multiple stamens of a flower, befitting the meaning of his name. One of his most notable features is the large scar running down the left side of Todo's face.
