Guys if tu have seen episode 90 of the 2014 season of fairy tail i want to know do tu think the anime has fully finished o do tu think it will continue

It's not finished, first they have to go through the history, which is Fairy Tail ZERO, then probably go back to the regular time stream. That happened in the manga, possibility it could happen in the Anime.

I have seen the episode .. there is continuation of the story.. I opened the vista previa of the siguiente episode I didn't understand it

IT CONTINUES PEOPLE IF ANYONE DOUBTS THAT THERE ISN'T GOING TO BE más EPISODE OF I DON'T KNOW ANYTHING I'M GOING TO KICK U TO THE CELESTIAL SPIRIT WORLD THROUGH WHEREVER

its continuing right now in fact. There are 265 episodes right now. It will end unfortunately but it will end a happy ending.

I believe it will still continue because it won't end till both Zeref o Acnologia have been defeated.

I believe that it will be continued.
