Tidus is a star athlete in his city. He is famous, has all the ladies, and simply loves his life. However, one day, his city is attacked by a mysterious evil, and an old family friend shows up, initiating his quest. He is magically taken to the world of Spira, where that evil, known as Sin, ravages the planet and its people with death and destruction. Sin is a punishment for the world's crimes, however, Tidus has been chosen to stop it. He meets up with Lady Yuna, a summoner (and daughter of a high summoner). Summoners can call the power of the fayth; aeons. Aeons are mighty and mystical creatures. Yuna quests for the Final Aeon: the one power that can slay Sin. Tidus joins as one of Yuna's many guardians, and travels with her to obtain the Final Aeon. However, the quest goes much deeper when high-ranking religious leaders betray the teachings of Yevon, the celestial overlord of Spira, and Yevon himself condones it. Tidus battles with his past and his true self while trying to sort his emotions and get back home to his world. Corruption of religion and the terror of Sin take the adventure to unimaginable heights.

Two years have passed since Sin was destroyed.
Since defeating Sin and becoming high summoner, Yuna has lived on her childhood home of Besaid Island, and the predictable days pass by one after another. Isn’t this simple happiness what she always wanted? Still, Yuna senses something is missing... Then, one day, her former guardian Rikku comes to Besaid and shows Yuna a movie sphere.
The recording is of him.
Or is it? Yuna can’t tell whether it’s him or just someone who looks like him. “Let’s go look for more clues!” The voice is Rikku’s.
If it is him, Yuna might be able to see him one more time. If not, Yuna will probably never see him again. No matter what the truth may be, the answers she finds may change things forever.
Yuna begins another journey.
