After the great disaster of 2008, a war that destroyed the planet, the world is now largely ocean with the continents having sunk. Conan lives on a remote island with his grandpa and nature, never having seen another human being. But one day a mysterious girl, Lana, washes up on his beach. The two become quick friends, but she’s soon kidnapped and taken to Industria, a technological remainder from the world before. Conan leaves his island in pursuit, braving new lands and many hardships with new friends and enemies just beyond the horizon.

In ancient times, a great battle was waged between a master mage, Enno, and an evil demon goddess, Karuma. 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, unleashes her family's powers to summon Zenki.
