In the future, an organization known as the GGP has seized control of the world. Rin Ogata was a promising young ballet dancer, but she suffered a severe injury while performing and decided to quit. Years later, while in college, she stumbles upon a club building and soon becomes fascinated by a transforming motorcycle-like robotic vehicle called a "Rideback". She quickly discovers that her unique ballet skills, particularly her balance and finesse, make her a natural on a Rideback. However, those same abilities also land her in serious trouble with the government.
