Welcome to Gaia! ::

Yuna: is the female protagonist and seventeen year old human summoner. Final Fantasy X's system has her use healing magic in the game, while also allowing her to summon powerful magical entities called "aeons." Already known throughout Spira as the daughter of High Summoner Braska — the man who, ten years earlier, brought a brief respite from Sin's destruction (The Calm) — Yuna has chosen to embark upon the summoner's pilgrimage to become a High Summoner herself. The burden of this responsibility is expected to see Yuna journey to temples across Spira, acquire the aeon from each and ultimately summon the Final Aeon in a battle that will claim both its life and hers. Her weapons are a variety of staves, and she is able to summon eight aeons during the game. As Yuna's story progresses she gradually becomes more open and falls in love with Tidus. Because Yuna's mother was an Al Bhed she has heterochromia, so one of her eyes is green and the other blue, a reflection of her mixed heritage.

Paine: She is eighteen years old, and uses a sword for combat. Paine appears in Kingdom Hearts 2 with an updated chibi and fairy-like design, as do Yuna and Rikku. The three are "treasure fanatics" working for Maleficent. After the three are abandoned by Maleficent during a raid by the Heartless, they join a committee to restore Hollow Bastion upon a false promise of reward by Donald Duck.

Wakka: is characterized by a long reddish-orange quiff and a Besaid Island accent (the real-world equivalent of which would be a Hawaiian accent). As such, he uses such speech-mannerisms as saying "brudda" for "brother" and finishing sentences with "ya?". His name means "water" in Ainu. In addition to being one of Summoner Yuna's guardians and childhood friends, Wakka is also a twenty-three year old professional blitzball player and captain of the Besaid Aurochs, a team that — as of the beginning of Final Fantasy X — went ten years without winning a single game. He uses blitzballs as his weapons in battle.
