In the future, a group known as the GGP has gained control of the planet. Rin Ogata was a bright young ballet dancer who sustained a major accident while performing and decided to retire. Years later, in college, she walks upon a club building and is immediately drawn to a morphing motorcycle-like robotic vehicle known as a "Rideback." She quickly discovers that her particular ballet abilities of balance and elegance make her a natural on a Rideback. However, those same abilities get her in hot water with the authorities.
