Final Fantasy X is a story of the young summoner-to-be Yuna. She, along with her guardians Kimarhi, Lulu, and Wakka, are on a mission to destroy Sin, an evil 'monster' that destroys villages, kills people, and is somehow connected with the water. On this quest, Yuna and her guardians meet blitzball star Tidus and care-free (Yuffie, Selphie?) Rikku. Yuna is willing to die trying to get rid of the evil Sin. Along this adventure, many interesting people will be met, and all the characters will learn something new.
