Wang

Wang is the leader of a violent faction of the Heiron that is especially hostile to the Seidoukai. He has a personal grudge towards Hyoudou and describes their relationship as "natural enemies". He has a clearly perverted taste for young boys and keeps boy servants around. It's implied Wang owned Yuki while he was a prostitute, and he takes possession of Yuki again in order to use Yuki to get at Hyoudou. He is a manipulative and cruel person who brutally kills his brother Ashiei without a second thought. He is being manipulated by Reiji though he doesn't know it.
