Ryo has short blue hair with two black square hair clips on the right side of her bangs and yellow eyes, with a mole on her left cheek. Ryo's uniform consists of a collared white shirt worn with a black ribbon, a dark blue pleated skirt, black leggings, maroon or brown loafers, and a matching long sleeved sweater. This outfit is similar to most Japanese high school uniforms. Despite her expressionless exterior, Ryo is an eccentric girl with a mischievous sense of humor around friends.
