Due to their high intelligence, they created killing machines in the laboratory where the first government made them. Resulting in more killing machines presence lately. The second government was then established by Marshal Astra, the only successful Metalforce in the hope to protect humans from the killing machines. Humanity and new Artificial Intelligence aka. Angels made-for-war joined together to stop the continuing machinery war that had been continued for over 200 years.
