The Star Doll

The guild had been disbanded and brought back together again by Natsu after his year of training solo. He had managed to bring together most everyone, but there was one girl who had evaded him even years later, though he could not tell why. Her scent had long since disappeared from her regular haunts and even her past employers at Sorcerer Weekly hadn't heard from her in ages. Then one day on a job a few cities over, Team Natsu stumble across a pink haired little girl with a peculiar smell, a necklace of keys, and an achingly familiar doll that she absolutely refuses to hand over. Eager to learn about her connection to her keys and unable to leave a child on their own, they escorts her back to the Fairy Tail guild. But geez, there was something about that doll....

Fairy Tail belongs to Hiro Mashima. This plot belongs to me.
Be warned, I watched the dub. So that means there are certain manners of speech or phrases that might be changed or excluded, but nothing big. Also, I finished the Manga. Because of that, there may be some spoilers.
Also, Nalu.
