On Titalos Island in the middle of the great Belion Sea is a peaceful village called Anfog. Tucked away in a corner of this village is a simple garage from which the sounds of hammering can be heard. Inspired by tales of Sky Captain Schmidt, a young man named Yuki is building his own airplane. "Someday I'll leave this village and fly over the sea, all the way to the mainland!" he thinks to himself. His eyes grow distant, imagining the vast sky stretching out in front of him.

Nearby a flaming arrow slices through the night. A horse-drawn carriage races through the forest just ahead of its pursuer "I must get to Arcriff...!" This thought alone allows Alfina to face her fears and take this dangerous journey.

Fate will these two young people together just as the world is about to fall apart.
