A knight who was once known as the empires hero after slaying the demonic dragon Draguel, a noble from a respected family who was outcasted by the noble society on the day of her debut, a scientist interested in medical science and machinery, an assassin who worked under the command from the emperor and a witch who was burnt at the stake. Their lives were turned around in an instant once the empires ruler Aulus Vitellius fell sick and died. The empire they had once known was gone, filled with corruption after the deceased Emperor's half brother Augustus Vitellius had become the empires new ruler. These five victims decide to take matters into their own hands after seeing how corrupted the empire had become. "Even if we gain power, even if we somehow gather an army, even if we start a revolt, how are we going to win against a man who holds the whole empire including 100 mountains worth of soldiers in the palm of his hands?" "Simple, just assassinate the bastard."
