Daughter of high summoner Braska, the second-to-last summoner who was able to defeat Sin 12 years ago. Like her father, she has made an amazing deed of defeating Sin 2 years ago, only this time Sin is gone for good.

With the disappearance of Sin summoners no longer needed to be sacrificed in order for people of Spira to live in peace - therefore aeons (or fayth) were no longer needed as well. Following Sin's defeat Yuna now throws away summoner job - she has chosen more advanced form of artillery... dual guns!

She joins forces with Rikku and Paine to form YRP, a group of sphere hunters. Of course, they're not the only group of sphere hunters on the face of Spira.
