An elementary school girl Sasami is chosen by Juraihelm Queen candidate Tsunami to restore the balance of good and evil in the universe - a precondition for Tsunami's ascension. Sasami transforms into Pretty Sammy to fight the evil Pixy Misa. The universe of the series is basically sweet and innocent with evil nothing more than a word. The goals of the villains are nothing more serious than to embarrass Pretty Sammy and make her bawl. Nothing other than the monsters are seriously hurt in this show.
