About

In 2035, a gargantuan meteorite named 'Astranite' collided with Earth. However, instead of the expected total annihilation, the high-dimensional, high-density magical energy within the Astranite began to spread across the entire globe. This energy started affecting all life forms. Non-intelligent life underwent mutations, while intelligent humans absorbed the pure mana, leading to the emergence of individuals with supernatural powers worldwide. As hideously mutated creatures began slaughtering humans and destroying cities, humanity rallied around the first awakened superhumans, eventually forming what is now known as the Hero Association. ---------------------------------------------------------- 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 powers and combat capabilities. A-Rank heroes possess combat power equivalent to a brigade, S-Rank heroes can annihilate entire nations, and Z-Rank heroes possess the power to stand against the world. ---------------------------------------------------------- Immediately following the Astranite impact, 'Core Zones'—areas where residual mana remains concentrated—were formed. These spaces are the most dangerous yet mysterious regions on Earth, serving as the primary source of 'Astrallum,' the most powerful magical mineral 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: Emergence of magical beasts capable of paralyzing a city; requires multiple B-Rank or higher forces. Calamity: Emergence of large-scale magical beasts requiring A-Rank heroes or higher. Extinction: Emergence of extinction-level beasts equivalent to S-Rank heroes, capable of altering continental geography. Magical beasts form colonies in the deepest canyons or massive forests where Astranite debris remains, while top-tier intelligent beasts establish strongholds to expand their influence.
