Nura

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.

Yokai continue to break the eight seals of Hidemoto, which keep their leader, the dark Hagoromo-Gitsune, bound and powerless. In Kyoto, the scene of the main battle, Rikuo's friend Yura and her allies face one of their own comrades, who is now possessed by an age-old yokai. Meanwhile Rikuo and his fellow Nura clansmen are speeding toward Kyoto via flying boat. But the followers of Hagoromo-Gitsune are determined to make sure their journey is anything but smooth sailing.
