Hoozuki
鬼灯
Hoozuki is the talented, sadistic deputy of the King of Hell, Enma. He tries to solve various problems in Hell. In his spare time, he takes care of the animals and raises Goldfish grass.
Hoozuki is a tall but slight oni (Japanese ogre) with black hair that parts in the middle and has a horn on his forehead. His ears are rather large and pointed, as are his fangs. Hoozuki's eyes are grey and slanted, with red markings at their sides. These red markings seem permanent as he retains them after washing and during his sleep. He wears a black yukata with red lining and obi with a Chinese lantern ( this represents both his name and symbol)embroidered on the back. He is rarely seen without his toothed metal club which is extraordinarily heavy, but Hoozuki's superhuman strength allows him to wield it easily. It is also noted by many women such as the Stone Princess and female minions think that he is rather good looking. Noted by Momotaro and King Enma to be similar in appearance to Hakutaku. He actually takes great care in his personal appearance.
He is very stoic and serious, rarely losing his cool under any circumstance (though he frequently blows his top whenever Hakutaku or Enma Daio are involved). It is also implied that he is very manipulative, shown in episode 13 where he admits to enjoying working for Enma as his right-hand man, only because this allows him to manipulate and control the Underworld from the shadows. He gets called a sadist often by various people, yet he himself denies it. '
Hoozuki seems to enjoy resorting to violent means to resolving problems, seen when he confronts Momotaro and tells him "This is Hell so let's settle this with violence". Hoozuki sees violence as the fastest way to deal with whatever difficulties he faces and takes sadistic delight in doing so. He is also proficient in inflicting mental anguish verbally, traumatizing Beelzebub so much after their first meeting that the prime minister of European hell vomits blood the next time he encounters Hoozuki. Hoozuki's sharp intellect serves him beyond affairs of the state, enabling him to win any argument and cow potential enemies such as Satan and Momotaro's three animal companions. Those who fall prey to Hoozuki's sharp tongue typically sink into depression, vomit blood or develop a serious phobia of Hoozuki the next time they encounter him.
Hoozuki is portrayed as somewhat unforgiving in nature as well, grinding several of his goldfish plants into juice and feeding them to Enma as punishment for them trying to escape from his garden patch.
