Living in the Shadows (a Jerza fanfic)

Erza Scarlet lived a fairly quiet life, or so it seemed to others. Jellal Fernandes was her childhood friend who started bullying her in order to gain popularity. When he sees something abnormal happen with Erza, he follows her to figure out what it was. What he discovered would change his life forever. He discovers her to be the infamous Titania, a leader of a supposed criminal gang. In actuality, this gang wasn't a gang at all, and they weren't evil at all. Yet, they were forced to live in the shadows, to be protected from and to keep from being framed by the Balam Alliance, led by Zeref. Jellal, pulled into this incident, tries to fix their problems and tries to help them with Zeref. Will they be able to succeed?

(Some SAO characters and other anime characters. Mainly fairy tail)
If I didn't make it completely clear, credit for the idea to Out Of The Shadows and again I forget the author. This is also mentioned in chapter one.
