In order to harness this profound new energy, mankind develops advanced 'coils,' devices that link to and use the power of Dimension W. However, by year 2071, the New Tesla Energy corporation has monopolized the energy industry with coils, soon leading to the illegal distribution of unofficial coils that begin flooding the markets.Kyouma Mabuchi is an ex-soldier who is wary of all coil-based technology to the extent that he still drives a gas-powered car. Kyouma is a 'Collector,' individuals with the sole duty of hunting down illegal coils in exchange for money. What started out as just any other mission is turned on its head when he bumps into Mira Yurizaki, an android with a connection to the 'father' of coils. When a series of strange events begin to take place, these two unlikely allies band together to uncover the mysteries of Dimension W.
