Hidden on Tenrou Island was a Celestial Spirit Key. It contained the Fairy DragonSlayer, AKA the mascot of Fairy Tail. The name of the spirit is Kyofu Masuta, a 13-year old girl who was originally Master Mavis's best friend before sacrificing herself for Fairy Tail. She was sealed so deep inside the Celestial Spirit World that not even her fellow Spirits could find her, and the only ones with knowledge of her are the Masters of Fairy Tail. However, when Master Makarov sees a possible opening to get Kyofu out, he brings Lucy with him to Tenrou Island. However, releasing her would also release the other spirits locked in the Deep Spirit World. And that is when things get tricky.
