I fight for Spira. The people long for the Calm. I can give it to them. It's all I can give. Defeating Sin, ending pain... this I can do.Yuna
Yuna is the female lead of Final Fantasy X and Final Fantasy X-2. She is the daughter of High Summoner Braska and an unnamed Al Bhed woman, who died when Sin attacked her ship at sea. The Al Bhed woman was the sister of Cid, who is the father of Rikku, meaning that Rikku and Yuna are cousins.
Final Fantasy X
Braska then begins raising Yuna, until eventually he decides to become a Summoner. To do this, he enlists the help of a fallen monk named Auron and Jecht, a man who suddenly appeared in Spira. Braska began his pilgrimage to collect all the aeons to obtain the Final Aeon. While on the island of Besaid, he asks Auron if he will take Yuna to Besaid after the pilgrimage.
Kimahri then travels to Bevelle, where he meets Yuna and takes her to Besaid. At Besaid, she becomes close friends with Lulu and Wakka - in fact, the relationship is referred to as Yuna being a younger sister to the pair. Eventually, she decides to become a summoner, and refuses to allow Lulu and Wakka to change her mind. She, Lulu and Kimahri travel through the Besaid Cloister of Trials. Once there, she begins praying to the fayth to allow her to become a summoner.
A day later, she leaves the fayth as a summoner, only to find Wakka and another man (named Tidus) in the room. She then completes her training by summoning the aeon Valefor. She then begins a trip to Kilika with Wakka, Lulu, Kimahri and Tidus. Thanks to her own encounters with Jecht, she is the only person who believes that Tidus actually comes from Zanarkand (other than Auron, who was the one that brought Tidus from there).
At Luca, Yuna hears a rumor that her father's guardian, Auron, is somewhere in Luca. She begins a search with Kimahri and Tidus just before the opening Blitzball match. Kimahri ends up in a fight with two other Ronsos, and during that time, Yuna is kidnapped by the Al Bhed in hopes of making the Besaid Aurochs lose to them. However, Tidus, Kimahri and Lulu manage to rescue Yuna, while the Besaid Aurochs win their first match in 10 years.
While travelling towards Djose Temple, Yuna is caught up in a mission called Operation Mi'ihen, where she witnesses Sin kill most of the Crusaders. Upon reaching Djose Temple, it is confirmed that she has chosen Tidus to be her guardian, and she also recieves the aeon Ixion.
On the Moonflow, she is yet again kidnapped by the Al Bhed. This time, the machine is underwater, so Tidus and Wakka go down to rescue her. The group later realize the pilot of the machine was really Rikku, who becomes Yuna's final guardian.
Yuna and the group then escape, only for them to be trapped under the ice. Yuna is then kidnapped by the Al Bhed on Bikanel Island and taken to their home. However, the Guado attack and take Yuna to Bevelle, where she is to be wed to Seymour.
She is forced into marrige to save her guardians, but then jumps off the church, and is saved by Valefor. She then escapes to the Bevelle Fayth, where she recieves Bahamut. However, the group is caught and she is tried for murder and treason. However, she escapes into Macalania Woods with the rest of the group.
In the woods, the famous Suteki Da Ne love scene appears, where Yuna and Tidus kiss underwater.
Yuna then travels to Zanarkand, where she defies what the other summoners have done and kills Yunalesca, so as not to sacrifce one of her guardians to be the Final Aeon for her.
Yuna then enters Sin, where she manages to break the cycle and defeat Sin once and for all, becoming the High Summoner of the Eternal Calm.
Final Fantasy X-2
Two years have passed since Yuna defeated Sin. Back on Besaid Island, her quiet life is shattered when she is contacted by Rikku, who has a gift from Kimahri - a sphere he found, which shows a man who bears a striking likeness to Tidus, her love who "disappeared" after the defeat of Sin.
Just before the events of Final Fantasy X-2, Yuna's Garment Grid is taken from her by a group called the LeBlanc Syndicate. Using her garment grid, the leader, LeBlanc, is pretending to be Yuna. Rikku and Paine enter the concert held by the fake Yuna is hopes to get Yuna's grid back. Yuna is left in Luca wearing the Mascot dressphere, where she pretends to not be 'Lady' Yuna.
After getting her grid back, the group begin the search for spheres which may contain more clues of the man in the sphere.
At the end of Chapter 1, Yuna goes to Kilika Island, where the group stole a sphere, and obtain a sphere. The sphere details events which the Gullwings wish they didn't have. However, they see 'him' in the sphere, who talks about a girl called Lenne.
Towards the end of Chapter 2, Yuna, Rikku, Paine, Leblanc, Logos and Ormi enter Bevelle, and manage to get down through where the old fayth used to be, into an underground section where the original sphere was found. Towards the end of the dungeon, the group must fight Baralai, the leader of New Yevon, regardless of whether or not the player gave the sphere to him. However, they beat him and enter the Vegnagun chamber, only to find Vegnagun gone, and a twisted Bahamut in its place. This is the first of the Dark Aeons.
At the end of Chapter 3, the group has visited Besaid Temple to rid them of Dark Valefor and Kilika to beat Dark Ifrit. They then go to Djose Temple, where they defeat Dark Ixion. When they enter the chamber of the fayth, Dark Ixion walks in, and charges into Yuna, knocking her down into the Farplane, where she sees 'him', who turns out to be Shuyin.
In Chapter 4, Yuna starts a concert on the Thunder Plains, where she wears the Songstress dressphere. As part of the concert, Shinra creates a sphere-screen so that people at the back can see. However, the songstress dressphere has an effect on the sphere, and people end up seeing images of Lenne. Shinra then reveals that the person trapped inside the songstress dressphere is actually Lenne.
In Chapter 5, the group travels into the depths of the Farplane, where they encounter Vegnagun. They defeat it, only for them to be attacked by Shuyin. They trick him into thinking that Yuna is Lenne, but then his vision clears and he sees Yuna instead of Lenne. They beat him, and Lenne encourages him to return to the Farplane.
While then crossing the Farplane, Yuna is encountered by the little boy who resembles Bahamut. He asks Yuna if she wants another moment with 'him', to which Yuna agrees and the fayth recreates a real version of Tidus for her.
- Yuna appears in Kingdom Hearts II as a small fairy, along with Paine and Rikku. The three are mercenaries working for Maleficent, although they are willing to help Sora at the promise of treasure.
