Slaying Monsters in the Card World

In 2100, the world was thrown into turmoil. Disasters struck one after another, and monsters invaded. Conventional weapons could no longer stop them.

Humanity rejoiced. Under the pressure of the monsters, a world powered by cards had come into being.

Humanity designated that year as Year One of the New Era.
