About

In 2035, a gargantuan meteorite named 'Astranite' collided with Earth. However, instead of the expected total extinction, the high-dimensional, high-density mana within Astranite began to spread across the entire globe. This mana started affecting all living organisms. Non-intelligent life forms underwent monstrous mutations, while intelligent humans absorbed the pure mana, leading to the emergence of individuals with supernatural powers worldwide. As these hideously mutated creatures began slaughtering humans and destroying cities, humanity rallied around the first awakened superhumans, eventually forming what is now the Hero Association. —————————————————————————- Year 2060, Earth Hero Association Astra Association Ranks: Apprentice - D-Rank - C-Rank - B-Rank - A-Rank - S-Rank - Z-Rank Ranks are assigned based on innate or acquired supernatural abilities and combat prowess. A-Rank heroes possess combat power equivalent to a military brigade, S-Rank heroes have the power to annihilate entire nations, and Z-Rank heroes possess the ability to stand against the entire world. —————————————————————————- Immediately after the Astranite impact, 'Core Zones'—areas where residual mana is concentrated—were formed. These spaces are the most dangerous yet mysterious regions on Earth, serving as the primary source of 'Astrallum,' the most powerful mana mineral that humanity can mine. Astrallum is used to manufacture high-performance equipment and weapons issued to heroes. —————————————————————————- Disaster Ranks: Normal: Equivalent to conventional wild beasts; can be suppressed by D-Rank and C-Rank forces. Threat: Appearance of magical beasts capable of paralyzing an entire city; requires multiple B-Rank or higher forces. Calamity: Appearance of large-scale magical beasts requiring A-Rank heroes or higher. Extinction: Appearance of extinction-level magical beasts equivalent to S-Rank heroes, capable of altering continental geography. Magical beasts form colonies in the deepest canyons or vast forests where Astranite debris remains, while the highest-tier intelligent beasts establish bases to expand their influence.
