Who is the down-and-out boy in the underground city?
What is the Light Church's purpose?
What lies beyond the Antarctic ice wall?
What is the true nature of the world?
With the war that will destroy the world drawing to a close, everything will come to light.
The System comes from companions, weapons are seized from enemies, and scraps of life are eked out of the world. From the start, the only thing he owns is a light bulb.
This story takes place in a world after the Third World War. With the end of the nuclear war and the onset of nuclear winter, the surface is no longer fit for human life. The survivors, led by the unified government, move into underground cities and gradually rebuild civilization. Yet this world hides a great secret. An unlucky boy from the lowest depths gets caught up in the enormous conspiracy and is hunted by the postwar unified government. Why are they after him? As the Illuminati, which has been pulling the strings all along, emerges from the shadows, the truth will be revealed.
