Itsuki "Ikki" Minami, is a student and a delinquent. Also known as the "Unbeatable Babyface", Ikki is the leader of the youth gang by the name of "East Side Gunz" (Hikatsuganzu). Upon his return home, after being humiliated by a Storm Rider team called the Skull Saders, Ikki discovers a secret hidden from him by his benefactors, the Noyamano sisters. The sisters belong to a group of Storm Riders who go by the team name of Sleeping Forest. In the anime, learning the sisters' secret angers him and he steals a pair of Air Trecks, abbreviated as "AT". (In the manga, the sisters give a pair of ATs to him and invite him to skate with them.) Ikki eventually settles his grudge with the Skull Saders, but in the process he receives more than the simple satisfaction of revenge. Determined to experience the sensation of "flight" for as long as he can, Ikki is quickly engaged in the mysterious, irresistible world of Air Treks.
