Yuki has idolized the legendary pilot Schmidt since he was a young boy and has been trying to build his own ever since. Loving the freedom of flight, he dreams of one day leaving his small island and reaching the mainland. In the woods not far away, Alfina rides alone on a horse-drawn carriage. She is a Communicator, one of the few who can speak with the Guardians, gods that protect the world. She is hurrying to a temple to take the place of her brother, Emelious. Resentment of his obligated duty as a Communicator has turned Emelious into a cruel and violent being filled with hate. Fate will bring together Yuki and Alfina just as the world is about to fall apart.
