King Glames leads denizens of the Dark World to conquer both Vecanti and Earth, seeking a home for his people before the destruction of his planet. Against this common foe, Yuko Asou fights together with Cham and Valna. Furthermore, the mystical Valis sword wielded by Yuko Asou is shown to be capable of more than what Yuko has accomplished with it thus far. During the course of the game, Yuko rescues Cham from kidnapped and Valna from captivity. Later, they visit the ruler of Vecanti, Nizetti, and unleashes the Valis blade's full potential, which culminates in a climactic battle between the three girls and Glames as well the returning antagonist from the first game, Rogles. Yuko defeats them both, and for her dutiful and unwavering service, she is permitted to step down from being a guardian and become a goddess in Vecanti, leaving Earth behind forever. The Valis sword retires to the heavens, and Vecanti prepares itself for prosperity, while Cham and Valna wave goodbye to Yuko as she departs to take on her new role.
