In a world that knows nothing of magic, there's a hidden society of people with incredible abilities. After joining the Fairy Tail guild and partnering with a crazy pyromaniac by the name of Natsu Dragneel as well as his flying blue cat, Lucy Heartfilia begins to learn that everyone has secrets - some of which even lie within her own family - and that nothing is ever as it seems.

Runaway Lucy Heartfilia finally gets to join Fairy Tail, house and school for homeless kids. What she didn't expect was to be brought there by a pink-haired, pyrotechnic black belt with a blue cat, that she might start falling for him, or that this boy could help her solve the mystery behind the golden keys left by her mother that hold a deadly secret. High school ninja AU. Nalu.
