Doubtful. I mean, but Jude and Lucy confirm she died. Yes I know the Lisanna thing, but that was a very rare circumstance. I think maybe she was sent into the future. Like Anna's daughter, I think maybe they used her power like strength of his Magic Power, was used in bringing Natsu and the others there. And after all the Eclipse Gate requires about as much Magic Power as an Etherion shot.
