One thousand years ago, all manner of evil creatures beset Earth. Only the high priest, Ozuno, could control the guardian demon named Zenki and protect the world. Fearful that no one would ever be able to control the destructive Zenki, Ozuno sealed the creature in a stone monument before he passed on. 
 
In modern day, a young priestess named Chiaki Ozuno uncovers the monument. Strange demonic objects known as the Seeds of Evil have been appearing once again, and with them come doom for all mankind. Chiaki's only chance is to summon Zenki! Will she find a way to control him, or will Earth's salvation spell her destruction?

Master Ozune Enno centuries ago bound the demon/guardian Zenki into his service to fight evil, particularly Karuma and Zenki was sealed away once the job was completed until needed again. Schoolgirl Chiaki Enno as the Enno descendant is able to break the seal on Zenki, but he is also bound in a child-sized form when not fighting evil because he is defiant so she must use the power of the bracelet which appears on her wrist to bring him to full fighting stature. The Seeds of Karuma cause people to turn into monsters embodying a vice which Zenki defeats so that he can eat the Seed. Set 3 adds demon/guardian Goki who boosts Zenki's power to the next level and usually provides a shield to protect the rest of the team of Chiaki, her Grandma Saki, Saki's brother Abbot Jukai, his assistant Kurabayashi and sometimes helping out hero Sohma Miki. When not fighting, Goki returns to his human form of a boy, Akira.
