Bai Chen, the "Child of Misfortune," is brought to Fairy Tail by Mirajane, and thinks he has finally found a home.
But the blood moon sends his magic into a frenzy, transforming him into a demon who controls black vines and attacks his companions. The World Tree pendant around his neck unexpectedly brings him back to his senses.
His grandmother's disappearance, the schemes of a purple-robed figure in an obsidian palace, and visions of the apocalypse in his dreams all point to the secrets he carries: the World Tree, the end of all things, and the coming of the Age of the Gods.
To uncover the truth and grow stronger, Bai Chen leaves the guild and sets off on an unknown path of cultivation. But the shadow of the blood moon has yet to fade.
