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 rumble! Rikuo leads his Night Parade of a Hundred Demons in a street fight against the 88 Demons of Shikoku. But Rikuo doesn't know that the maniacal leader of the 88 Demons, Tamazuki, is wielding a secret weapon: the Devil's Blade, a legendary sword that absorbs the energy of the demons it slays. When the sun rises, the Paranormal Patrol visits a girl who's being visited by a jyami, a type of ghost that only haunts outcasts.
