Yuko Aso was once an ordinary high school girl. One fateful day, her destiny was forever changed when she was chosen by Valia, the queen of the Dreamland, to be the next Warrior of Valis. Meanwhile Rogles, the Dark King of Vecenti, began his cross-dimensional assault with his powerful Vogue generals at his command.
