Robots and humans... they were once incompatible existences. Well, that's ancient history now!

Worldview
Hundreds of years ago, there existed humanity with special abilities—the Arcline—and humanity with high intelligence—the Noeline. The two races had been in conflict since ancient times, and the rift between them was very deep.

──In the midst of a long war, the Noeline, who were suffering repeated defeats against the Arcline's attacks, used their high intelligence to create machine lifeforms that would fight even if wounded or their legs were broken—the Robots.
However, the Robots were far more difficult to handle than the Noeline had imagined, and eventually, even the Noeline could no longer control them. As a result, the Robots, who refused to obey, took revenge, and the Noeline were wiped out in less than a year.
That threat then extended to the Arcline, and within a few years, the sparks of war and all conflict vanished.
Humanity came to an end.
──And now, hundreds of years later. While Robots live like people, Guest, the sole survivor of humanity, is...
