Final Fantasy X-2 is the first direct sequel in the history of the series. The events of the game take place two years after Yuna and her guardians defeated Sin in Final Fantasy X, and peace was restored in Spira. The Yevon religion has all but disappeared, and two political factions begin to compete for dominance: the Youth League, led by Mevyn Nooj, and the New Yevon Party, led by Praetor Baralai. Meanwhile, Yuna's cousin Rikku finds a strange sphere that mysteriously shows an image resembling Tidus, Yuna's one and only love. Rikku brings the sphere to Yuna. Determined to discover the truth behind the mystery, Yuna organizes a journey of 'sphere-hunting', to collect more spheres scattered around the world and perhaps find Tidus.
