In 2072 wireless coils draw limitless power from a hidden fourth dimension, and Kyouma Mabuchi makes his living as a Collector, confiscating the illegal coils that bend that energy to dangerous ends. He hates the technology and works alone, until a job puts him beside Mira Yurizaki, an android built by Shidou Yurizaki, the physicist who founded New Tesla Energy. Mira attaches herself to him, and the two chase contraband coils toward the secrets behind Dimension W and the company that powers the world.
