Daughter of High Summoner Braska. Honest and determined, Yuna embarks on a polgrimage to obtain the Fial Aeon and defeat Sin. Yuna is learning the mystical art of summoning aeons-powerful spirits of yore.

Since Yuna already knows the Cure spell and will learn many more protectvie and restorative spells as she travels across the Sphere Grid, bring her into the action whenever other party members need healing or status ailments cured. Her physical attacks are ineffective, but by summoning aeons Yuna can cause more damage to enemies than any other character.

Yuna's Overdrive is Grand Summon. Any aeon so summoned will appear with a full Overdrive gauge. After the aeon uses its Overdrive attack, its gauge will revert to its previous condition. Thus, the previous gauge isn't wasted.
