Daughter of High Summoner Braska.
Honest and determined, Yuna embarks on a pilgrimage
to learn the ancient art of summoning
in order to defeat Sin

Since Yuna already knows the Cure spell
and will learn many more protective 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.
