Natsuo is a young man of above average height with a rather well-built figure. He sports white spiky hair with two short strands hanging down the middle of his forehead. He also has gray eyes with fairly long eyelashes. In his younger years, both sides of Natsuo's hair had two streaks of crimson red. It is unknown why these same details are absent on his current appearance, although it's possible that he could have dyed them or they became white like Toya's hair did.
