Deep Blue Frontier

This world is no longer humanity's.

Since the monster assaults known as the Invasion began, the world has been transformed. Humanity had long since lost control of the Earth, and for a long time it has survived only by barely clinging to existence within drastically shrunken territories after losing the lands it once ruled. Taking those places instead are beings called monsters. Humanity has tried to seek a way to survive by putting forward those called Hunters, who have awakened special powers, but the situation has only grown increasingly bleak.

Can humanity win the struggle for survival against the monsters?

In the little time left before the reprieve runs out, can it find an answer for the future?

The story begins now.
