During the Heian period, roughly 1,000 years ago, Ojarumaru, a young boy from a noble family, grows weary of his privileged existence. Meanwhile, three demons steal Enma, the demon king's, power-stick, only to lose it. Ojarumaru discovers the stick and uses it to travel to the present day. There, he befriends a young boy named Kazuma and joins his family. As time passes, Ojarumaru makes many new friends while evading the comedic attempts of the three demons—Akane, Kisuke, and Aobee—to retrieve the stick.
