On Fairy Tail chapter 341 cover page it said “The TV Anime project restarts! …After Natsu vs. Sting and Rogue, the anime ended and now the next anime series project has finally started. We will let you know the details as soon as possible, stay tuned!“
Also Mashima then updated on his Twitter in English: “I will start the sequel of the anime.“
And in Japanese: “FAIRY TAILテレビアニメ新シリーズ(続き)決定しました。みなさんのたくさんの応援のおか
which will translate to: “FAIRY TAIL anime new series I decided to continue. It is thanks to the support of many of you. Thank you.“
We predict that Fairy Tail will start airing in summer 2014. Stay Tuned!
