In the far future of humanity in the 24th century, the lack of supply is the cause of starvation, and the uncontrollable population causes the loss of habitat land. The sea turns into a dried desert, the woods turn into polluted facilities, and the soil is contaminated. The view of the rising sun from the horizon has been obscured by smoke and cinder. The signs of extinction aren't that far away.
Just when all hope seems lost, a miracle intervention alters mankind's history and its fate of destruction. The machine called "Shifter" was created, but to find the truth, they need an observer, the pathfinder, which is the birth of "Regulator of Humanity Advancement."
