Haruhiko is a tall teenager with dirty blonde hair, hidden by a brown cap with an attached pair of black goggles near the front of the hat. When this hat is removed, it’s shown that his hair is tidy and kept for, though having one area where it sticks out.

He's shown to wear a long-sleeved white shirt, which transitions into a brownish pink colour, though it's unknown if this is dirt or not, with a blue gem necklace worn over it. Over the shirt he wears a sleeveless dark brown jacket
