Air Trecks, also referred to as AT, are futuristic, motorized inline skates that have become the latest craze sweeping the nation. While every AT is equipped with a speed limiter, a group of daredevils called the "Storm Riders" are bold enough to tamper with the device. Using ATs in underground battles, individual teams bet valuable AT parts or team emblems—their symbol of pride—to dominate the streets. Itsuki Minami, a middle school student infamous for getting into street fights, lives in this era. Always striving to reach heights no one else can, this reckless punk will break through any obstacle in his path, accompanied by his best friends Kazuma Mikura and Onigiri. However, it is only when he discovers a pair of Air Trecks in his house that the path to his true desire finally opens: to rule the skies.
