Leopold is a boy of average height with long, messy vermilion hair. He keeps a third of his hair in a braid while leaving the rest in a messy, spiky hairstyle. One of his prominent features is the red markings around his turquoise eyes. After taking a vow to become the next Wizard King, he sports a dark-colored, diamond-shaped marking on his forehead. He's a nobleman and the second son of the Clover Kingdom's House Vermillion. He's 2nd Class Intermediate Magic Knight of the Crimson Lion squad.
