The Story of Evil is a set of Vocaloid songs that tell the story of an evil, greedy, stuck-up princess. She ends up being captured and executed by the people for her tyranny. However, she had a twin brother who looked very much like her and would do anything for her. He had actually forced his sister to take his place as he let the people capture him in place of the princess (he dressed in drag XD). It's actually a really sad and dark and depressing set.
