Prologue: The Girl and The Rabbit

I don't know who I am. I don't know where I come from. All I know is, my name is Seren Constella, Fairy Tail is my home, and its people are my family and friends. They have done much for me, so I will do what I can to return the favor. So in order to do that, I will do anything and everything in my power to protect them from harm. Even if it means sacrificing my body and soul for their sakes. OCx?
