Sting x Reader( Light and Dark don't mix)

A little girl is looking for food one day in the woods when she runs into a boy the same age as she is.
her helps her get home only to find that her mother or rather dragon mother has vanished. they look every where but don't find her so during the night while she is asleep this boy takes her to a near by guild hall so he would know that she would be safe.
That guild hall becomes her new home, they become the only people she can rely on. As time moves on after the Tenrou team disappears the remaining fairy tail guild members notice just how different she is from everyone even the rest of the dragon slayers. Some say her magic is Weird, Some say it's Wrong, but Everyone knows that she can't control it. Most of the time she is perfectly fine but others she's blacking out and waking up with more knowledge and memories than before she would pass out. No one can figure out how or why this is happening.
