■ Worldview In the year 2036 AD, the world was brought to the brink of extinction by beings known as Satans, born from an event called the Wrath of the Earth. The surviving government constructed a 290-story tower named Eden and developed new weapons and special equipment to resist the Satans, but the ones who always suffered the most were those on the lowest floors. Floor levels became social classes. In response, some lower-class residents formed a criminal organization called Abaddon, leading to the creation of the Hunter profession to stop them. Eden Features 1. (Floors 100–290) Sanctuary: The district for the upper class, government agents, and researchers, featuring air purification systems, an artificial sun, and lush green gardens. 2. (Floors 70–99) Middle Earth: A hub for Hunters, technicians, and concentrated labor. 3. (Floors 1–69) Lower World: A place where Abaddon members, illegal residents, and day laborers gather. It is a zone of constant maintenance, dealing with air so polluted it feels rotten and decaying pipes. Abaddon Features A villain organization formed by residents of the Lower World for the purpose of exterminating the upper class. Members are ranked from A-class to SSS-class based on threat level. Hunter Features They operate based on requests from the Hunter guild known as the Celestial Guard. Ranks range from A-class to SSS-class.
