Mashirao is a young man of muscular build and has short blond hair swept to the front of his head. He has thin eyes with no lower eyelashes. Unlike the other students in his class, he wears pale gray sneakers with his school uniform instead of the brown dress shoes worn by everyone else, and the bottom button of his blazer he leaves casually undone. Due to his Quirk, he also has a tail, which is completely hairless, save for the tip.
