Ex-ballerina Rin's first experience aboard a RideBack turns into a nightmare when the malfunctioning machine races toward a cliff - but instead of suffering a fatal accident, Rin feels alive like never before.

Rin is challenged to a race by the leader of the RideBack Club, Tamayo. She's tough, she's outspoken, and she's also the nation's top rider. If Rin can hold her own, Tamayo just might take her under her wing.

The national tournament arrives. Tamayo's set to defend her title, and Rin's racing, too - but with Fuego ineligible, she's forced to mount an unfamiliar RideBack.

Shoko is caught in the middle of a terrorist attack, and Rin rushes into the chaos atop Fuego. Her daring rescue attempt appears doomed when she's cornered by armed soldiers - until a mysterious savior appears.

The media and the authorities alike are searching for the mysterious girl who penetrated the GGP blockade. The RideBack Club decides to lay low - but they've already caught the attention of several prying eyes.

A RideBack gang is on a crime spree, targeting police and civilians alike. When Rin learns that her brother is among the thugs, it's bad enough. When she sees the action taken by the government against the group, it gets even worse.
