Air Trecks, also known as AT, are motorized and futuristic inline skates that are the new craze taking the nation by storm. Although each AT comes with a speed limiter, a community of daredevils known as the "Storm Riders" are brave enough to tamper with the device.

However, it is when he discovers a pair of Air Trecks in his house that the path to his true desire finally opens: to rule the skies. [Written by MAL Rewrite]
