Rikuo Nura is part human and a quarter yōkai (demon). Because he is only a quarter yōkai, Rikuo is able to turn into his yōkai form only after sunset, when the moon is out; he turns back into his human self when the sun rises. He lives in a house full of spirits along with his yōkai grandfather. Trying to escape his fate, he does good deeds in order to avoid becoming a yōkai, despite his grandfather's wish that Rikuo succeed him as master of the Nura yōkai clan. Rikuo is a different yōkai because he helps humans. He eventually comes to terms with his demon blood and decides to take up the position of Young Head of the Nura house. Multiple factions aim to stop him or usurp his position, and he must gather friends and allies, a new Hyakki Yakō under his banner of "Fear".
