Rikuo Nura is part human who is a quarter yōkai, becoming a yōkai during the night. He lives in a house full of yōkai 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 the Third Head of the Nura Clan. Rikuo is different because he helps humans. He eventually comes to terms with his yōkai blood and decides to take up the position of the Third Head of the Nura Clan. 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".
