In the magical kingdom Juraihelm, Tsunami is in line to be crowed queen but must complete a test first. She must choose someone to make the world a better place. Sasami is given the task of delivering a CD from her mother's store to a spooky mansion. When she gets there she is met by Tsunami who tells her she will become a magical girl. She endows Sasami with magical powers and sends Ryo-Okhi with her as a guide. Matters are not easy, however, as Tsunami's rival, Ramia, wants the crown and will do anything she can, including creating her own magical girl, Pixy Misa, to stop Tsunami from being crowned.
