Nura: Rise of the Yokai Clan, Vol. 15

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.

As the ancient yokai Hagoromo-Gitsune prepares to give birth to the new reincarnation of Nue, ancestor to the world-killing Gokadoin clan, Rikuo rushes to learn new skills and battle moves that will ready him for his biggest battle yet.
