Mashima had asked fans earlier this year to wait until he can announce some "good news" since the first television anime adaptation of Fairy Tail ended. Mashima addedon Twitter at the time, "It's actually not over yet. I can't say more than this, but I hope you watch the rerun starting in April and wait for the day I can announce some good news. […] Anime is not the end. Don't stop believing." The series concludedwith a "To Be Continued" title card. Mashima later announced that the television anime project had relaunched.
