In ancient times, a great battle was waged between a master mage, Enno Ozuno, and an evil demon goddess, Karuma. Unfortunately, Enno didn't have the strength to defeat her alone and was forced to call upon Zenki, a powerful protector demon. After Karuma was defeated, Enno sealed Zenki away in a pillar located inside his temple. 1,200 years after this epic battle, Enno's descendant, Chiaki, spends her days showing tourists around her hometown of Shikigami-cho and doing exorcisms to pay the bills. One day, two thieves enter the town in hopes of opening a seal in the Ozuno temple and releasing the hidden treasure from within. However, what actually pops out is a dark entity that attaches itself to the henchmen, transforming them into demonic beings. After this transformation, they begin a rampage through the temple, terrorizing poor Chiaki. It is now up to this young progeny to unleash her family's powers to summon Zenki and save Shikigami-cho from these demons, as well as the evil entities sure to follow in their footsteps.
