While the day belongs to humans, the night belongs to yokai, supernatural creatures that thrive on human fear. Caught between these worlds is Rikuo Nura. He's three-quarters human, but his grandfather is none other than Nurarihyon, the supreme commander of the Nura clan, a powerful yokai consortium. So, Rikuo is an ordinary teenager three quarters of the time, until his yokai blood awakens. Then Rikuo transforms into the future leader of the Nura clan, leading a hundred demons. A YOKAI WITH WINGS DARKER THAN NIGHT Rikuo has successfully defended his classmates from the vicious Inugami's mad-dog attack. But that battle is just a hint of what's to come. The sinister Tamazuki has remained in his human form so far, but now he's unleashing his true form: a ferocious yokai leading the 88 Demons of Shikoku, a disciplined demon horde hell-bent on taking the Nura clan out. With Nurarihyon missing, Rikuo must step up as a warrior and a leader.
