Yohi

While technically a demigod, Yohi's duty resembles that of a demon warrior. He takes care of (assassinates) any person who has violated the council's code of conduct [per the council's orders]. Careful though, Yohi is not an assassin or guard dog, he is a legitimate council member with political sway. Initially, Yohi was just someone not afraid to his get hands dirty and do his own dirty work, but Yohi is now seen as an enforcer of the council rather than a member. 

Quiet but unhinged -- While Yohi is not one to speak much, his demeanor is quite volatile.
