The war between the Empire and the Void has raged for thousands of years.
In order to bypass the frontal battlefield, the void race launched a space storm to tear apart the reality structure within the empire. Countless rifts were created as a result, and travelers from other universes - humans, animals, and even objects - poured into the empire's territory through these rifts.
Intelligence is coming from the front: The Void is exploiting these rifts. Every trace left by travelers is a path they can follow. Those people who have been forgotten for thirteen hundred years are becoming the map of the void invasion.
The Time Traveler Recycling Center was thus established.
Hound X9-724, a police department law enforcement AI with 127 years of service, was transferred to this newly established department. His mission: Go to every coordinate where abnormal space fluctuations have occurred, find the traversers, confirm their identity, assess the impact, and deal with them according to the "Measures" - return them if they cooperate, force them if they don't cooperate, and eliminate threats to space security.
