gray's lost sister

Okay I've seen alot of Natsu sibling ones and I made a Lucy sister story but then it hit me when i decided to rewatch Fairy Tail for my two stories when I got to episode when it talks about Gray's past. Then I thought 'What if Gray's family didn't die and even so what if he had a sister who survived' so here you go and thank you lucky commenter who help me decide what type of ice wizard she would be. Ok well read the first chap. Enjoy.
