A supernatural saga of a 13-year-old by day, and a leader of a demon clan by night—straight from the pages of Weekly Shonen Jump!
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.
Key members of the Nura clan plunge into battle with the Gokadoin clan, but as the fighting wears on, Rikuo struggles to keep his clan energized. Meanwhile, Ryuji seeks a way to penetrate the Gokadoin stronghold…Aoi Spiral Castle!
