Why Can't I remember?

When Acnologia attacks Fairy Tail at Tenroujima, Lucy wakes up after a week. But wait... SHE'S SIX? What happens when Lucy losts her memory and starts training with her new magic power? Full summary inside. I do not own Fairy Tail nor the cover image. Please review for pairings in this fanfic. Looking forward to make new chapter! Rated T for safety and language!
