300 years after the Fairy Continent was ravaged by the Great Cataclysm, the demons began to stir. The key to saving the continent lay in the Seven Divine Artifacts that had resurfaced. By chance, two teens from the Three Domains of Humanity got their hands on the Peerless Pearl, one of the seven artifacts. This granted them the power of symbiosis, which the demons were hell-bent on preventing from uniting with the other six artifacts. Against all odds, the fearless duo embarked on an adventure to bring together the races of the Fairy Continent and stand up to the demons, providing the weaker human race with more time to develop.
