Utena Hiiragi is a shy middle schooler who idolizes Tres Magia, the magical-girl trio that protects her town. When a mascot named Venalita offers her powers, Utena expects to join them, but she is recruited instead by the villain organization Enormita and reborn as Magia Baiser. Forced to fight Tres Magia, she discovers that watching the heroines struggle awakens a sadistic streak she never knew she had. This ecchi magical-girl series follows her as she embraces the role of villain rather than hero.
