Welcome to the world of Storm Riders, where motor-powered inline skates called "Air Treks" take extreme sports to a whole new level. Those who dare to ride with these high tech devices risk life and limb in a struggle for fame, power and wings to take to the sky. Enter Ikki Minami, the toughest fighter on the east side of town. He rules his school, takes on violent gangs single-handedly and lives with the Noyamanos; four sexy sisters with a surprising secret. And after a humiliating defeat to a terrifying gang of Storm Riders, the sisters welcome him to the world of Air Trek, where his strength, speed and ambitions soar to brand-new heights. Now, with powerful new wings, he must protect his friends, his school and his pride in fierce Air Trek battles known as "Parts Wars." One mistake could cost him everything, but each victory brings him one step closer to becoming the king of the sky.
