This book is dedicated to everyone who loves Girls' Frontline.
When he regained consciousness, he found himself in a wasteland. Nuclear radiation and mutated beasts had become the masters of this world, while humans outside the safe zones had no choice but to scrape by underground.
The world had been reduced to this simply because humanity discovered the ruins of an unknown civilization. During their surveys and excavations, they began researching and deciphering the unique "Collapse" technology found within. Then, due to inadequate containment, Collapse Fluid wreaked unprecedented havoc on the outside world. Cities evaporated, the population plummeted, and vast swathes of habitable land remained contaminated for sixty years.
Yet despite all this, the last two human factions continued to wage war against each other.
And all of it was caused by "Collapse."
Civilization's progress had ground to a halt, and the embers of order were slowly dying out. "Collapse" ushered in a new era. Though it brought scientific advances, it brought even greater devastation to the world.
A fully evolved new human, the culmination of the technological achievements of the Third World War, was given a new name. Accepted by this world, he embarked on a path no one could have imagined: destroying every ruin and saving the planet. Even if it meant... sacrificing himself.
