Commissioner O

Member of the judges. Slightly shorter than the other executives, he has white, shoulder-length hair and dark-colored skin. O has won the first G.O.H tournament and, as such, is regarded by his colleagues as the strongest judge. His calm and perky character often makes him act as a mediator between the irritable R and the rash Q, often at each other's throat. He wields the Charyeok "Dragon slayer" which enables him to summon and command dragons as well as controlling fire. O is the one who recruited Mi-ra for the G.O.H Tournament and appears fearful of the young woman, always avoiding eye contact with her and calling her "a monster".
