In a world where Grav-Shoes let people fly, the aerial sport Flying Circus has competitors racing between buoys and tagging opponents to score. Transfer student Asuka Kurashina arrives at Kunahama Academy, discovers the sport, and joins the school's FC club, where classmate Masaya Hinata, who walked away from competition after a crushing defeat, becomes her coach. Teaching a beginner who can barely stay airborne pulls Masaya back toward the sport he left behind.
