Set in the Heian period, about a millennium ago, Ojarumaru, a young noble, becomes weary of his privileged life. At the same time, three demons pilfer the power-stick of Enma, the king of demons, and subsequently lose it. Ojarumaru finds the stick and uses its power to transport himself to the modern era. There he befriends a boy named Kazuma and joins his family. As time passes, Ojarumaru makes many new friends while evading the comic attempts of the three demons, Akane, Kisuke, and Aobee, to recover the stick.
