The young man who is looking for the Gods who fled to other realms. He is sarcastic and violent. His dancing abilities are top notch but his singing leaves something to be desired. He is the only disciple of Ran Saiwa, one of the 8 sages. He is treated like an outcast by many.
There are hints that he has something to do with the Tenko (not Tenkou). The tenko is a nonliving egg that is said to have a mass amount of power. The Tenko is also the base source of the fruit tree that allows the people to travel to the normal world for a short amount of time. Ichiyou has a faint smell of that fruit that the God's find a bit attractive. This is probably why he can travel to the normal world without eating the fruit. He has small wings under the bandages on his neck which are numb. One of the characters said that this might be the reason he can't sing. But when the atmosphere is purified, however, his singing is incredible. It can even make an enemy god bow it's head to him.
