Aoi is a tall young man with a very defined, heavy muscular build and tan skin, comparable in height to Satoru Gojo. He has small black eyes and shoulder-length black hair that he keeps tied in a top-knot bun. A large, noticeable scar runs down the left side of his face. Aoi has an extremely eccentric and boisterous attitude, often coming off as a battle-crazed meathead to his peers because he enjoys posing and showing off his physique. He is direct and impatient, but also surprisingly open-minded.
