(based on the anime Air Gear) Chesley is a typical American, most of the time. She lives with her two older brothers and has a secret identity. She is Angel, a well known hero in the Air Trek world. Every summer she used to come to Japan, but for the last eight years she hasn't. When she finally does, she meets an Air Trek team that completly change her point of view on almost everything, as well as reunites her with an old friend. Of course, it's not all fun and games for Kogarasumaru.
