The Surviving Traitor

Since the end of the war more than 300 years ago, mankind has finally unified, established the Unified Earth Government [UA], and changed the era to the New Calendar (NA Calendar/NEO AGE). The desolation caused by war has awakened mankind and made it decide to take the path of peace. Humanity unites to restore the earth's ecology to 52% of the population and environmental levels before the war two hundred and seventy years later. However, after that, the conservative forces of the empire headed by Ed Bellin and the opportunist forces headed by Arman Zaroff tore apart the United Human Government. In NA-324, the BELLIN Empire, CARRIFEA Trade Alliance, and APELT Federation were officially formed as three major forces on Earth, as well as the establishment of numerous small countries. This marked humanity's return to an era of independent societies characterized by conflict between forces. However, in the later stages of the implementation of terraforming the earth, some asteroid meteorites from outer space fell into the uninhabited area of ​​the earth. The meteorites that were supposed to cause damage actually changed the ecology of the crash area after falling to the earth. While meteorites changed the environment, they also attracted carbon-silicon-based metal-bonded life forms named [Ghost Beasts] from outer space, threatening and destroying the human living environment. In this scenario, humans created their own "steel behemoth" and competed with it. However, after gaining the ability to compete, the people once again returned to the situation of being oppressed. Therefore, the mysterious organization [Freedom Wing], headed by the mysterious man F, was established to pursue the return to the era of unification. The male protagonist Xing Yi, who belongs to the fifth preparation team, also accidentally joined the Free Wing and unfolded a story unique to this world.
