Ryung, Jin

He is Bi-wal's older twin brother by 3 hours, he did not become the king of hell because he was not supposedly blessed by the moon, which is why his hair is white, but because he is not blessed by the moon that makes him more powerful and many fear him because of that. He feels responsible because of Queen Hong's marriage to the king of heaven and wants to take Dong-Young away from Bi-wal to spare him from the marriage. (Source: Wikipedia)
