As you all know ... Yuna is the daughter of High summoner Braska, who died ten years ago. Yuna has a special talent.... She has the powers to summon Aeons( Valefore, Ifrit, Ixion, Shiva and... one more I won't tell though ). Which makes her a summoner. There are many summoners in the universe... but there is few in Spira the FFX world... So she is thought of as "famous".

Yuna's mission is to travel around the world, and go to all the Ebon temples and get all of her Summons , and then kill Sin. Although Sin was defeated Ten Years ago by Auron, Jecht, and High Summoner Braska. But, Sin is Jecht.. and Yuna does not yest know that.

At the last boss (Yu Yevon) Tidus tells the group that this will be his last fight.... Well, after they deafeated Yu Yevon , anf they get onto the ship Tidus starts to faintly disappeaer.... Yuna tries to go save/stop him and then she stumbles to the ground. Then Tidus looks at her sadly and says his final words to her "I love you!"
