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.

The Nura clan’s turf has been invaded! A mysterious set of travelers arrives in Ukiyoe Town to wreak havoc and challenge Rikuo in his position as the leader of Japan’s most powerful yokai syndicate. They even infiltrate his school! If Rikuo wants to maintain the Nura clan’s status and protect his human friends from the rival yokai’s malice, he’s going to have to call his hundred demons to battle and prepare for his biggest fight yet!
