The Grim of the Black Order

Cynthia Grim is not a normal girl, her way of life is simple kill everything that stands in her way and protect people if she feels like it, however, when she joins the black order and becomes an exorcist she meets Allen Walker, Lavi Bookman, Yuu Kanda, Leenalee Lee and many other people. When her friends learn about some of her past will Cynthia be able to keep them as her friends? This is my very first ever fan fiction and I hope that you will understand how terrible it will be and I might in the future re write it and improve it in many ways. The story starts about after the exorcists defeat lulubell for the first time and in the story they return back to the black order. I would like to ask you, the reader, to enjoy this fan fiction and I promise I will update regularly in addition Cynthia is my character based on what I want her to be and there is another character I'm adding called Everest and Everest is basically the character that dates Kanda in the end (Everest is a character my best friend wanted me to add based on her.) So all that is left to say is enjoy and sorry for the really long description.
