Balamb Garden (not a military school in this story) is her new highschool. There, she will meat Cloud Strife, Tifa Lockhart, Squall Leonhart, Rinoa Heartilly, and Aeris Gainsborough. Soon she'll find herself with Aeris dead, half-dead herself, and fighting for her life and the life of her friends. How did it come to this? However it did, Rayna Stone finds herself face-to-face with FATE.
