Yes, I still wonder how they are going to put E.N.D. inside the story, like maybe Natsu fails to kill Zeref in time and his powers run out so the demon is summoned to kill him or something. Then there's also the rest of the Spriggan 12, Acnologia and fights along with the rest of the storytelling, so I guess there is still a long way to go before this series actually ends.
