The universe is not just one. Within the overlapping layers of the multiverse, there exists another Earth that looks exactly like Earth.
In "MultiEarth Α0073", 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. However, this universe has been consumed by the mysterious powers known as the Stellaron, and the Antimatter Legions
Hiro 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". Though he is stationed in the backwater Archives Division, his true objective is to investigate Emorgy crimes across dimensions and the Stellaron disturbances across the galaxy.
Chasing these inter-dimensional threats, Hiro leaps through space-time, encountering the Gavans of various dimensions and joining forces to bring justice to the multiverse.
"Jo-Chaku!"
The Space Sheriff Gavans transcend the boundaries of the universe to strike down evil!
