War broke between humans and monsters about 7 years ago. The only saviors capable of fighting against the monsters, the "heroes", have been slaughtered and the last humans retreated to live in bunkers.

Or can this enemy prince be trusted at all? -Updates on Tuesdays/Fridays around once or twice a month-
