Humans have discovered a new dimension called Dimension W, which provides an endless supply of energy. Advanced coils have been created to use this energy, but by 2071, the New Tesla Energy corporation dominates the industry and illegally produces and distributes coils. Kyouma Mabuchi, a former soldier, distrusts coil technology and prefers to use a gasoline-powered vehicle. He makes a living as a "Collector," hunting for and selling illegal coils. However, his latest assignment becomes unexpected when he meets Mira Yurizaki, an android linked to the coil inventor. As unusual events occur, the two unlikely partners work together to solve the secrets of Dimension W.
