Humans have found a fourth dimension, Dimension W, and an allegedly endless source of energy within it in the near future. To harness this profound new energy, humanity creates advanced "coils," devices that connect to and use the power of Dimension W. However, by 2071, the New Tesla Energy corporation has monopolized the energy industry with coils, leading to the illegal distribution of unofficial coils that flood the markets. Kyouma Mabuchi is an ex-soldier who is skeptical of any coil-based technology and still drives a gas-powered automobile. Kyouma is a "Collector," a person whose primary job it is to find unlawful coils in return for money. What began as just another mission has been flipped on its head.
