The Antonio Empire is the most powerful country in the entire galaxy. It has an iron triangle, the scheming His Majesty Antonio, the omniscient and omnipotent Imperial Marshal and the playboy and willful little princess. The three of them grew up with different personalities but lived in harmony. Until one day, His Majesty Antonio, who was increasingly ambitious, wanted to marry off the young princess to complete his plan. But before that, he had to get rid of everyone in the empire, starting with the marshal who was next to him in status but whose reputation was unmatched.
