Keigo is a man of over average height with a lean and slender build. He has feathery, golden blond hair that is swept messily backward, with some of the front tufts sticking up in arcs above his head, and he has faint stubble on his chin.
His eyes are golden-brown and rather triangular, with two small black triangles just below his tear ducts and in the top corners of his eyes, making them resemble those of a bird. His Quirk grants him a set of large, bright red feathered wings.
