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 ."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.
