In Final Fantasy X, the main character, Tidus, is a star player of blitzball, a full contact sport. After miraculously surviving the destruction of his homeland, he awakens among ruins and thereafter meets a young woman named Yuna.
As a summoner, Yuna must travel to distant temples and learn the secret art of summoning aeons-powerful spirits of yore, in order to defeat "Sin." Tidus learns that a thousand years in the past, mankind lived in spectacular cities and relied on machines for everything, until Sin suddenly appeared and destroyed all civilization.
