Gray Era: Sixty-One Years

Humanity once thought that war, plague, and nuclear weapons were the greatest disasters that civilization could face, until an abnormal life called "dirt" appeared. While several national orders were quickly defeated by him, a supranational organization hidden behind world politics, the World Affairs Council, also came to the forefront of history. In the sixty-first year of the Gray Era, the dirt war that has lasted for many years is coming to an end, but the real crisis has just begun. The World Council and the Federation, which had jointly resisted disasters in the past, completely broke apart. Intelligence agencies, the military, consortiums and secret laboratories were at war with each other. Europe, Africa, America and the Middle East were plunged into turmoil one after another. Young Alpha detachments are sent around the world to track down remaining dirt, prevent a nuclear crisis, and uncover a conspiracy that could change the human order. What they have to face is no longer just filthy monsters, but also war machines, political lies, and those who constantly cross the line in the name of saving the world. When the old world begins to collapse, the writers of history will create a new world.
