The mechanics of the battle system include 'EX Revenge' and 'Assist.' EX Mode functions exactly the same as the Final Fantasy game by collecting EX Cores around the battle map to fill up the EX gauge and transform the character into a more powerful state, which allows players to perform a powerful EX Burst attack should an HP attack land during EX Mode. Thus, the player must perform several Bravery attacks to steal Bravery points from the opponent so as to increase the power of their HP attack, as Bravery attacks do not cause any damage. Both characters start with a set amount of Bravery points, the number of Bravery points being equivalent to the amount of damage dealt by an HP attack.
Players are able to perform two types of attacks: a Bravery attack and an HP attack. The game consists primarily of one-on-one battles, taking place on what is known as a battle map where the two characters duel. Gameplay is largely reminiscent of Dissidia Duodecim Final Fantasy.
