Yuna

51

Daughter of High Summoner Braska. Honest and determined, Yuna embarks on a pilgrimage to obtain the Final Aeon and defeat Sin. Yuna is learning the mystical art of summoning aeons—powerful spirits of yore.

Tidus

39

He is a rising star blitzball player from Zanarkand, and the son of major blitzball star Jecht. After the gargantuan monster known as Sin attacks his hometown, Tidus is transported to the world of Spira. Lost, confused, and seemingly out of place, Tidus meets a newly-fledged summoner named Yuna, and her guardians. Yuna is to set out on a pilgrimage to put an end to Sin, and by joining Yuna on her pilgrimage, Tidus hopes he will find his way home.

Wakka

13

Wakka is the first person Tidus meets after washing up on Besaid, and befriends Tidus after being impressed by his blitzball skills. He is the captain of the Besaid Aurochs, a team that has never won a game. He grew up with Yuna along with Lulu, and views her as a younger sister. His late brother Chappu was a Crusader who lost his life while wielding a machina weapon. For this, Wakka harbors a resentment for machina, and bigotry towards the Al Bhed who use them, and uses his staunch following of the teachings of Yevon (which forbid machina) to further rationalize his hatred. His world-view broadens during Yuna's pilgrimage, and despite his bigotry, Wakka is a loyal friend, and helps Tidus come to grips with Spira.

Seymour Guado

11

As a maester in the temple of Yevon, Seymour has influence over Spira, but uses his power towards a sinister end. Seymour is the Minister of Temple Affairs, which maintains the temples' rituals and teachings and oversees the summoners. This position allows him the authority to handle records of the sealed histories. He is also the High Priest of Macalania Temple. Seymour is a skilled mage and a summoner himself.
