Leo has short scruffy grey hair, yellow eyes, and two lobe piercings with silver rectangular drop earrings. He's regularly seen wearing his headphones around his neck, with a design consisting of black, yellow, and white. Leo has a witty and cynical personality, his careless blunt remarks put him in a negative perspective with other students. His egotistical nature leads him to appear disobedient, compelled to follow his own interests when all other choices aren't of his amusement.
