In the near future, humanity has uncovered a fourth dimension, Dimension W, along with a purportedly limitless energy source contained within it. To tap into this profound new power, mankind creates advanced "coils," devices that connect to and utilize the energy of Dimension W. However, by 2071, the New Tesla Energy corporation has monopolized the energy sector through coils, which soon leads to the illegal distribution of unofficial coils flooding the markets. Kyouma Mabuchi is a former soldier who remains wary of all coil-based technology, to the extent that he still drives a gas-powered car. Kyouma works as a "Collector," a role whose sole duty is to hunt down illegal coils in exchange for money. What begins as just another mission takes a sharp turn when he encounters Mira Yurizaki, an android linked to the "father" of coils. As a series of strange events unfolds, these two unlikely allies join forces to uncover the mysteries of Dimension W.
