Plot

In the world of Heavy Object, the United Nations has collapsed, leaving the world divided between four powers - the Legitimacy Kingdom, the Information Alliance, the Capitalist Corporations and the Faith Organization. Following the development of Objects, armored fighting machines possessing vastly superior capabilities to conventional units and weapons, war has developed into a bloodless game determined by battles between Objects.

In a military base located on the frigid regions of Alaska, a mechanic-in-training named Quenser learns the ropes of becoming an expert in the field of Objects, and meets one of its elite pilots named Milinda. As their friendship develops, Quenser discovers that the real face of war is merely hiding behind the mask of bloodless defeat and victory...
