It's a stage adaptation of Fairy Tail that was announced way back in December. Seems to be covering the Oracion Seis arc and images of the cast have been released periodically ever since it was made public. So far we've seen Natsu, Gray, Lucy, Hibiki, Jellal and Lyon; names of the actors for some other roles (mainly the OS) have also been given.
