A time-traveling woman attempts to compete for the identity of the commander of Hyakki Yakou, and makes a wish to replace Rikuo Nuruo. But can the human heart be replaced so easily? Awakening the monster bloodline may not necessarily make you the commander-in-chief of a hundred ghosts. When the first person who swore allegiance was hurt, Rikuo also woke up, but his sealed bloodline completely changed. He was no longer a human during the day and a monster at night. He was Nura Rikuo with a quarter of the monster blood!
