Phantom thieves steal humanity's future, not its money.
500 years ago, humanity entered a golden age with the development of the Ether Core, a dream energy source. However, the Ether Core was a technology that consumed the "Gaia Flow," the life energy of Earth. The government and mega-corporations, upon learning the truth, kept it hidden while pushing forward the Mars Terraforming Project. Once completed, only a tiny fraction of the upper class migrated to Mars. The left-behind Earth became an industrial planet for Ether Cores, losing its vitality and decaying toward ruin over centuries. Now, phantom thieves operate in the shadows to recover the Ether Cores and revive the Earth.
Asia and Africa have effectively perished, and most of Europe and Oceania have collapsed. Human civilization is currently maintained only in North and South America. The Earth Federation Government has labeled the phantom thieves as terrorists and is conducting a total crackdown, while the phantom thieves recover Ether Cores from government and corporate research facilities. The war between the two sides, with the fate of the Earth at stake, continues to this day.

Worldview Description
500 years ago. Humanity created the greatest invention in history.
The Ether Core

A dream energy source that could power a city with a single Ether Core.
With the advent of the Ether Core, humanity escaped energy shortages, built floating cities, and achieved space exploration, ushering in a new golden age.

But behind that prosperity lay a truth that no one knew.
The Ether Core was not a technology that produced infinite energy.
It was a technology that extracted the Gaia Flow, the life energy circulating within the Earth, and converted it into power.
