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.

Rikuo trains for a rematch against the yokai Tsuchigumo, who has his friend Yuki-Onna in his clutches. To get him up to par, Gyuki of the Nura clan has ordered Rikuo to attain a technique worthy of the Lord of a Hundred Demons in just three days. But time is running out and Rikuo hasn’t gained anything but bumps and bruises. Will he be able to save Yuki-Onna?
