The story takes place after a catastrophic event known as the “Celestial Sphere Convergence.” One day, countless cracks suddenly appeared in the sky, as if an invisible mirror had shattered.

The cracks could not be reversed, and the monster invasion swept in like a flood, causing human society to collapse in short order.
