In this world, there were ranks that determined your life. From lowest to highest, the ranks were: F, D, C, B, A, and S. The lower ranked you are, the worse you get treated by everyone in this world. But Scaramouche didn't believe that. He thinks that everyone should be judged for their personality, not just a mark. If you were at least a B ranked, you could work for the hero commission, to train and protect citizens. Scaramouche was one of the highest and most feared heroes.
