In the year 1972, humanity discovers a limitless, clean energy source drawn from "Dimension W," a fourth dimension beyond the spatial X, Y, and Z axes. Harnessing this power are Coils, revolutionary devices that revolutionize global
infrastructure. By 2071, New Tesla Energy holds a global monopoly on these Coils, but a black market thrives on illegal, unregistered "illegal coils," which are far more dangerous and unstable.Enter Kyoma Mababuchi, a cynical "collector" who despises Coils, relying instead on old-fashioned gasoline-powered cars and physical combat. His quiet life tracking down illegal coils changes when he is hired by New Tesla Energy to apprehend a mysterious robot girl. Kyoma captures the android, who calls herself Mira Yurizaki. Mira is no ordinary machine; she was built by Dr. Shido Yurizaki, the brilliant, reclusive scientist who originally discovered Dimension W, before he apparently died in a mysterious mansion fire alongside his family. Unlike standard robots, Mira possesses human-like emotions, a beating artificial heart, and the unique ability to interact directly with Coils.Despite his initial reluctance, Kyoma forms a reluctant partnership with Mira, registering her as his official assistant at the New Tesla-backed recovery agency. Together, they embark on dangerous missions to confiscate illegal coils, which frequently mutate users into monstrous beings or cause localized dimensional anomalies. Along the way, Kyoma must confront his deeply buried trauma. Ten years prior, he was the elite captain of the Grendel squad, a military unit that utilized prototype coils during a catastrophic tragedy known as the Easter Island Incident. The event cost Kyoma the lives of his beloved younger sister and his squadmates, leaving him with an obsessive hatred for New Tesla’s technology.As the duo delves deeper into the underworld, they cross paths with Loser, a charismatic masked terrorist determined to expose New Tesla's darkest secrets, and Lydie and Elizabeth Prince, ruthless fixers with their own agendas. The overarching conspiracy centers around the enigmatic Prince Salva-ori-Tibesti, who seeks to gather all seven "Numbers"—prototype coils imbued with immense power and fragments of Dr. Yurizaki's consciousness.The narrative culminates in a high-stakes convergence on Easter Island, the
restricted zone where the dimensional experiments originated. Kyoma, Mira, and their allies must infiltrate a massive underground facility to stop a catastrophic dimensional collapse orchestrated by shadowy corporate elites. Inside, Kyoma confronts ghosts from his past, discovering the true origin of Dimension W and the tragic fate of his fallen comrades. In the final, explosive confrontation, Mira uses her unique nature to stabilize the tearing fabric of dimensions, proving her humanity. Kyoma finally finds a measure of inner peace, accepting his past while forging a genuine bond with Mira as they continue their journey together in a rapidly evolving world.
