Yesterday started in Japan the official BRAVELY DEFAULT FAIRY’S EFFECT CBT in Japan. You only need a Square Enix account to join the CBT but the tester users number is limited to 5000…until now!
Square Enix today added 3000 more available slots so now totally 8000 people can test the game.

If you are interested in it just create a Square Enix account (on the Japan page) and download the CBT client to your Android device. The CBT runs until November 22, 2016.
