Resume : A new fad by the name of "Air Trek" (a futuristic evolution of inline skating) has swept the nation's youth and all over gangs are being formed that compete in various events using their A-T. Ikki is a middle-school boy who is the toughest street-fighting punk on the east side of town, on top of which he lives with four gorgeous sisters who took him in when he was a kid.

It doesn't take long before Ikki finds out about the world of Air Trek and is propelled into a fate he had not foreseen.
