@Misk: Even though her keeping it makes little sense given that, at least from my understanding, she just took it over in Sayla's body and forced Sayla to unknowingly use it to summon Elfman, this is Fairy Tail. If Mashima has no other way of having Mira win a fight in the upcoming Spriggan battles it will be brought back with no explanation and used to grant her a win ( .__.)

Just sayin'
