Story
"All people meet in the sky!"A group of boys and girls have their first real encounter with the sky - an encounter which provides the foundation for their new shared dream: to soar to the far side of the clouds, on wings into which they've poured their hopes and wishes.
The setting is Kazegaura - a lovely little town where the wind blows pleasantly. Today, a boy named Aoi Minase waits for the wind with his friends on a hill lined with windmills.
Once again, they await the time for departure - to take off on the sprawling, white wings of a glider.
The sky above stretches out to infinity. Their goal: the highest point in the sky possible.
