The story takes place in a barren frontier where people trade goods with each other in order to help each other survive. The Kotobuki Squadron are bodyguards for hire, led by a strict but beautiful squadron leader, an unreliable commanding officer, and a true artisan of a crew chief. Alongside pilots who do not lack for personality, they take to the air in dogfights, letting the engine noise of their Hayabusa fighters ring out in the skies. (Source: Anime News Network)
