Mobile application developer Cygames announced at Tokyo Game Show (TGS) 2015 that its Android and iOS RPG fantasy mobile game Granblue Fantasy will be adapted into anime. Cygames producer Kouichi Haruta revealed that the animation production will be done by A-1 Pictures and Aniplex. Further details about the anime will be revealed at Cygames' September 20 stage event at TGS. Guests at that event include Miyuki Sawashiro, who voices Catalina Alize in the game.
Granblue Fantasy began its service in December 2013 on the Mobage platform and features music by Final Fantasy series composer Nobuo Uematsu. It uses turn-based battles with characters of different classes gaining levels through experience and using various abilities. Animation studio Lay-duce previously produced a promotion movie for the game.
