We are in 2116 and the world has changed profoundly. A century earlier, a major change revolutionized people's lives, transforming them into being with perfect efficiency but unable to experience any emotion. By now everyone lived life together with their own clone, perfect copy of themselves, with whom they spend their entire existence. Everything was created by the three Great Fathers, born a hundred years earlier, absolute leaders of this revolution because of which there is no longer friendship, family and love.

X1 will try to change the course of history by returning in 2016 to prevent the disappearance of feelings helped by its X2 clone, left in the future, by Alice and the man without a double.
