Final Fantasy X-2 is a game set two years after Yuna's journey to defeat Sin. The people of Spira have accepted the use of machina and turned away from the teachings of Yevon, ushering in a Machina Revolution where they believe that machina can be beneficial as long as used properly. Despite this newfound peace, Yuna still feels an emptiness in her heart that prevents her from moving on with life. One day, she finds a mystical sphere containing imagery of what may be a Blitzball player she thought was gone forever and embarks on a quest to find him and get closure for their unexpected parting - even if it means never seeing him again. This is Yuna's story.
