One of the candidates to become the next demon king that is found by Suiu of the Four Heavenly Kings.
He has a nice face, but his personality doesn't match, he doesn't care about popularity and he won't repeat an order once he says it.
He's the lowest rank host at the club 'MAOH'.
Because he's never raised his rank, he's known by the disgraceful name of MAOH's watchdog, but he doesn't really care about it.
