Autoplay is a special feature that, when activated, allows the game to automatically select character abilities during a battle. To activate Autoplay, tap the Play button located below the Pause button on the left side of the screen. Tap the Play button again to deactivate Autoplay.
 
You will still be able to select enemy targets while Autoplay is activated. To do so, simply tap the enemy you want your characters to attack. Your characters will continue to attack the same enemy until the enemy is Downed or until you select a new target.
 
A Ninja Star rating of 2 or more is required before Autoplay can be used.
