Saotome Alto is a boy living in the Macross Frontier colony who loves to fly but is restricted by the small sky of only two kilometers high. During Sheryl Nome's concert, Alto almost crashes into Sheryl while flying but catches her. However, their brief connection is interrupted when aliens known as the Vajra attack the colony. Sheryl and Alto disagree on how to handle the evacuation with Sheryl prioritizing her own safety as a celebrity.
