Nura: Rise of the Yokai Clan, Vol. 2: Rikuo vs. Gyuki

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.

When the Kyuso yokai clan kidnaps Rikuo's classmates Kana and Yura, Rikuo transforms into his yokai form to save them. But the plot is far from over. It turns out Gyuki, a top officer in the Nura clan, secretly masterminded the attack! Unfortunately, Rikuo learns of this deceit just as he's embarking on a camping trip to a mountain renowned for yokai activity. Is Rikuo walking into a trap?!
