less than half of humanity survived what was called "the final war", where the world powers fought to centralize power in a single government, during the war period, prior to nuclear attacks, many governments experienced with humans to create perfect soldiers, meta-human prototypes before the rectifiers, among which some still survive wandering the suburbs of the old district, hidden from the rectifiers with orders to annihilate all previous prototypes, some of them are part of a subversive group called ronnin wolf. This post-war world still suffers the remnants of a nuclear and bacteriological war, the world government led by "The One", an unknown figure who presents himself as the irrefutable leader of humanity, is unknown and his image was never revealed to the Humanity, the only reproductions of it are given through the obligatory appointments on the giant virtual screens located in the squares located in the center of each district, where only one silhouette can be seen, this occurs once per solstice, and is accompanied by ceremonial celebrations, his image is revered by some as that of a God. Surveillance technology is extreme, facial identification drones patrol districts and rectifiers, humanoids at the service of the One, harshly enforce the laws of "The Unification" holy book written by The One, laying the groundwork for the laws, ethics and morals of This new order, the inhabitants of this unified world speak a single language, conglomerate of Spanish, English, Chinese and Russian. After the bacteriological epidemic, we were all injected with mutation identification microchips, which at the least sign of contagion, are taken by a rectifier to the control towers, from which few return, and those who do return without remembering their past, some they have the theory that it is a plan of the One to rectify subversive thoughts before they occur.
