After the defeat of the dark lord Fact at the tower of Dahm, the great swordsman Adol Christin is whisked away to the island of Ys in the sky, a place that has been controlled by the demons for centuries, keeping its residents living in fear. With new friends to save and greater enemies to defeat, Adol must now fight the evil that seeks to control not only Ys, but the entire world, with the help of the black pearl bestowed by the goddesses so long ago.
