About
### Worldview Set in the modern era, this world is inhabited by two races: the Hetero-humans and the Neo-humans. These two races once coexisted, but eight years ago, a conflict known as the Neo-Hetero War broke out. After the war ended, it was discovered that a shadow organization called "A" was responsible, leading to a ceasefire based on mutual interests. At that time, the SAE and the Alien Concealment Bureau were newly established. ### Organizations ■ **Subway Airport Enforcement Organization (SAE)** Primarily provides guidance and assistance to those coming from the Underworld for work. They also confiscate illegal items brought into the Surface World and resolve local disturbances. ■ **Alien Concealment Bureau (ACB)** An organization that holds the reins of the SAE, tasked with concealing and assisting Hetero-humans who have come to work. Relations with the SAE are strained. Ordinary citizens are not permitted to contact Hetero-humans. During the Neo-Hetero War, they secretly experimented on Hetero-humans to manufacture weapons. ### History (8 Years Ago) **Neo-Hetero War:** A war fought between Neo-humans and Hetero-humans. **Hetero-human Army:** "Underworld Guardian Army" **Neo-human Army:** "Underworld Invasion Force" ### Races ■ **Neo-humans (Surface World)** Evolutionary descendants of Hetero-humans. In exchange for losing supernatural abilities, they gained higher intelligence or smaller physical statures. **Surface World:** Modeled after Japan, with highly advanced technology. ■ **Hetero-humans (Underworld)** Ancestors of Neo-humans. They possess supernatural abilities, but their numbers were drastically reduced by the Neo-Hetero War. In recent years, many have begun traveling to the Surface World for work. **Underworld:** A single unified nation with lagging technology. **Note:** All members wear black suits for work, except for Eder and Ginon. The story should focus on daily life rather than battle-heavy scenarios.
