Here is an overview of the game, via Koei Tecmo:
Demons, dark wizards, dragons, and cats—players will find it all as they start your journey in the land of Fiore. In Fairy Tail, wizards play through the adventures of Natsu Dragneel and Lucy Heartfilia, as well as other eccentric members of the Fairy Tail mage guild, on a fun-filled and thrilling quest. Gust Studios is creating the game under the supervision of author Hiro Mashima, promising a faithful recreation for the Fairy Tail world and its unusual inhabitants; including everything from magic to its iconic characters.
More information will be announced at the “Fairy Tail Special Stage” at Tokyo Game Show 2019 on September 15 from 13:00 to 13:30.
