The universe is not just one. Within the overlapping layers of the multiverse, there exists another Earth that looks exactly like Earth. In "MultiEarth ?0073", which has entered an era of cosmic coexistence, crimes involving the exploitation of energy-based lifeforms known as "Emorgy" are breaking out one after another. Reiji Doki, an investigator for the Galaxy Federal Police, is Gavan Infinity, the only person in the universe permitted to claim the title of "Space Sheriff Gavan". However, he is stationed in the backwater Archives Department. His true objective is to investigate Emorgy crimes across dimensions. Chasing these inter-dimensional threats, Reiji leaps through space-time, encountering the Gavans of various dimensions and joining forces to bring justice to the multiverse. "Jo-Chaku!" The Space Sheriffs Gavan transcend the boundaries of the universe to strike down evil!
