The Rouge Fairy

Lucy has been ignored for countless weeks now. This has made her cold, but what makes her change the most is when Team Natsu kicks her out in favor of member who recently came back from the dead, Lisanna Strauss. But somewhere, she stumbled upon someone, someone who gives her great power. She unlocks her true potential. But, even through all this, Lucy has one friend who has stayed with her, Happy Dragneel. After being broken so much, she decides to turn to a darker path, one filled with revenge and power. She becomes an assassin, one feared. Her very name strikes fear into the hearts of both light and dark mages alike. She is known as the rouge fairy.
