Yuna
- Age: 19
- Height: 162 cm
- Default dressphere: Gunner
- Description: The description Will spoil end of FFX but does not spoil FFX-2.
Two years ago, Yuna defeated the chaos that was Sin, and brought the Eternal Calm, but had to pay for it dearly. The spirits of those who died in the epic battle between Bevelle and Zanarkand 1000 years ago became the Fayth, and created a dream world of how their life was before the battle, eliminating the things that caused the trouble. Yunalesca, summoners, and two who died in the battle, whose stories are told in FFX-2, amongst many other things. One of Yuna's guardians, who also previously was a guardian for her father Braska, Auron, died after Braska defeated Sin, only to become it as all did. Because of this he could ride Sin between Spira and dream Zanarkand, and brought Tidus to Spira with him. The fayth's spirits com when called by summoners, in the form of aeons. They were required to defeat Sin, and so had to stay in Spira long after their time. When Yuna defeated Sin, their spirits were no longer required to stay, so they could at last rest. Tidus disappeared, as he was nothing more than a dream of the Fayth. As he was about to leave, Yuna confessed her love to him. When Rikku showed her a 1000-year-old sphere Kimahri found containing a man whose appearance matched Tidus', Yuna joined the gullwings to find him.

Shuyin and Lenne
1000 years ago, when the great battle began between Bevelle and Zanarkand, Zanarkand's summoners were sent to the front lines. Lenne was forced to go, and was prepared to sacrifice herself to save Zanarkand. Shuyin, however, was not prepared to lose her. A huge machine called Vegnagun was created as a weapon, and was stored under Bevelle. It was never used, as the gargantuan machine could not tell friend from foe, and would destroy all Spira if activated. Shuyin decides that if Lenne must die all creation must go with her. He had to be a psyco) While attempting to activate Vegnagun, Lenne comes and stops him, and during their reunion Yevon soldiers come and shoot the two. Shuyin survives and is taken to jaol, while what happened to Lenne remains unknown.
