Nura: Rise of the Yokai Clan

Rikuo Nura is descended from Nurarihyon, Grand Master of the spirit world, but appears to be just a normal kid. He usually just wants to live peacefully as a human, but when his friends and allies are in trouble, his spirit blood boils, and he transforms into Nurarihyon to wipe out evil! A new concept story combining spirits and chivalry! A piquant, gallant ghost action story!
