Nura: Rise of the Yokai Clan, Vol. 23: The Great Kyushu Yokai Battle (Nura: Rise of the Yokai Clan #23)

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.

Yura and Tsuchigumo are under attack in Tsuchigumo’s home territory of Kyushu! The Gokadoin clan's Hiruko, a descendant of the evil Seimei, is more powerful than they had expected. Meanwhile Rikuo seeks advice from his grandfather...How will he gather enough fear to defeat this fearsome enemy?!
