The political power will be supplanted by chaebols in the near future, and conflicts will persist as a result of competition for interests.
The Igodra Company found alien remains and equipment in the near-Earth universe, code-named [Urd]. They also found the Delta particle, an enigmatic particle that has never been understood by humans.
The equilibrium of human forces has been upset by the emergence of delta particles. Ygodra Corporation has created a potent extensible tactical exoskeleton called Aita, whose military might has surpassed that of the chaebol, by utilizing the special delta technology.

Ygodra Corporation constructed Gray City, a massive circular orbital base above the equator, and equipped it with strategic weapons in order to consolidate its interests.
Other chaebols band together to form the “Human Alliance” in order to attack the Ygodra Corporation because Gray City poses a threat to their interests.
Even though the Human Alliance ultimately prevailed in the war at great cost and the Gray City was rendered immobile, the Ygodra Corporation’s unwavering power remained intact.

After capturing Igodra Corporation’s artificial life body 01, which was based on Urd, during the war, the Human Alliance broke Igodra Corporation’s monopoly on Delta Technology by developing its own Delta Technology and Aita. This led to a period of conflict between the Human Alliance and Ygodra Corporation.
