Hyberion

A shinigami that seems to know Tina and Kotarou. He met with Yuma due to the encounter when he raided his room to take Tina back, but changed his mind afterwards. He immediately took a great interest in Yuma the moment he laid eyes on him. He then declares that he will "make Yuma his" after apparently getting rejected flat by Yuma instantly after his approach, much to Yuma's annoyance and disgust.
