Yorn gazes up at two massive cities floating in the sky and dreams of discovering their mysteries. Without warning, those mysteries come looking for him. Edenic assassins murder his father and Yorn is next on the hit list. A nameless old man and a mysterious young girl help Yorn on his quest to find his long-lost mother and the truth. Known as the God Hunter, Yorn leads a race against the dark designs of the technological overlords.

Legend tells of how long ago God became displeased with how unjust Humanity was, and punished them for it. But eventually a human arose and defeated God, which bled fog all over the earth. New gods were born from the fog who only watched over humanity, while the God Hunter faded into the mists of legend. That is, until he was found by an ambitious nation in a young boy named Yorun. Now he is on the run with his guardian Goshizoku towards an uncertain destiny, pursued by the comical Yanuesu and the dangerous Yurugaha, inhabitants of the great island Edens which float over the earth, while quietly keeping watch over him is a young girl with her own secret.—Anonymous
