Air Gear

Itsuki "Ikki" Minami runs the streets as a brawling gang leader until he gets his hands on Air Treck, motorized skates that let riders climb walls and tear through the air. Hooked on the rush, Ikki forms a Storm Rider team called Kogarasumaru and dives into the rooftop world of A-T turf battles. He soon learns the girls he lives with belong to the legendary team Sleeping Forest, and that every Storm Rider is chasing the summit known as the Trophaeum Tower.
