Move over, roller skates! The self-propelled, high-tech trick skates known as Air Treck have taken the world by storm. Itsuki ‘Ikki' Minami is a boy who'd love to get his hands on a pair of Air Trecks so he can fly through the sky like the beautiful girl he's seen over the rooftops, but he's left instead with being beat up by brutal, Treck-wearing ‘storm rider' gangs like the Storm Saders. However, Ikki's life changes forever when he discovers that his caretakers, the lovely Noyamono sisters, are actually members of a storm rider gang called the Sleeping Forest. They give Ikki his first pair of Air Trecks, and the rest is history. With new wings that allow him to soar like a bird, Ikki finds himself drawn into the underground world of the storm riders where battles, hot girls and fame await him. What Road will Ikki choose?
