In the near future, the plutocrats replaced the regime and fought for their interests. Igodra Company discovered the remains of aliens and their equipment in the near-Earth universe-code name [Ould], and then discovered a mysterious particle that humans have never known, called the Delta particle. The emergence of the Delta particle has upset the balance of human forces. With its unique Delta technology, Igodra has developed a powerful malleable tactical exoskeleton, Aita, with military strength to achieve absolute superiority over the chaebol. In order to consolidate its interests, the Igodra Company built a huge circular orbital base over the equator-Grey City, and carried strategic weapons on it. The existence of the Grey City threatened the interests of other plutocrats, who united to form a "human alliance" to attack Igodra. In the end, the human alliance won the war at a terrible price, and the Grey City was paralyzed, but the absolute strength of Igodra Company was not shaken. During the war, the Human Alliance captured the artificial life form 01 based on Ould, and then developed its own Delta technology and Etta, breaking the monopoly of Delta technology by Igodra, and the Human Alliance and Igodra entered the period of confrontation.
