There are those known as Soldiers.

These soldiers of the International Peace Alliance, also known as Force, are specialists of investigation with disciplined bodies and honed mind. The greatest part of them were known as Explorers in the past, those who were devoted to adventuring the world.

In the past there was a great war that engulfed the world. That war lasted for decades and ruined both land and air. Disaster responded to the foolish actions of men, and Eidolons appeared throughout the world.

For the sake of going up against that overwhelming power, humanity entered into a ceasefire. An organization was established to resist Eidolons, but was destroyed. It was a precursor to the International Peace Alliance.

Fifty years after the disaster. A youth from the borderlands set out to join the International Peace Alliance. The youth doesn't yet know that they are about to get involved with an event that changes the fate of the world.
