In the age of eternal war, 6000 years before the notorious gamer duo "Blank" comes to the world ruled by the god Teto, the humans must face the superior races in an unequal battle. Riku, leader of the humans, meets an unusual ex-machina on the battlefield one day, whom he baptizes with the name Schwi. She challenges him to a game and sets conditions that he cannot refuse. As an unfeeling machine, Schwi wants to learn from him how the human heart works. After pre-programmed initial difficulties, the unlikely couple begins their fight for peace between the different races. In order to lead the people out of oppression and end the eternal war once and for all, the two must put everything on the line.
