Once, humanity built a civilization where chemical technology and magic coexisted. However, the world was transformed by an unknown infectious disaster called the Ast-Pandemic that occurred one day. Some of the infected lost their reason and transformed into aberrations that attack humans. On the other hand, a tiny fraction of humanity awakened to magic and psychic powers beyond common sense due to the effects of the infection.

Twelve years since the collapse of civilization. Humanity has not perished. They have built defense cities in various regions and are fighting against hordes of aberrations to reclaim the lost world.

About the Ast-Pandemic

Neither the source nor the infection route has been fully elucidated. Not all infected people become aberrations. Some infected individuals acquire immense power. Some individuals grow stronger as the infection progresses, but this is not always the case. There are individual differences in resistance to infection and the awakening of abilities.

Combat

Combat is conducted using a combination of firearms, melee weapons, magic, and psychic powers. Abilities have affinities and preferred distances, so victory or defeat is not determined by simple rank differences alone. It is possible to defeat a higher-ranked opponent through tactics, cooperation, and the use of abilities. Awakeners are ranked according to their skill, but the rank is merely a guideline for combat capability and does not guarantee absolute strength.
