-SPOILERS (If you only watch the anime)- Mavis and Zeref are gone from Earthland, but what happens if they turn up with in Britannia with all of Zeref's demons running rampage across the realm? Meliodas and Elizabeth are ready to leave for the demon realm, but what happens if a mysterious golden key turns up before they leave? Will Fairy Tail have to get involved again? What is the key? Will Mavis and Zeref ever actually die? === Disclaimer: All characters belong to either Hiro Mashima or Nakaba Suzuki. This is set after Alvarez arc. Also set just before Elizabeth and Meliodas attempt to go to the demon world. Btw, I watch the anime and read the manga for both of these and I watched the anime first. So if the accuracy in this ends up being in between the animes and the mangas, I apologise.
