Miracle²'s debut event draws near, and Kanon invites her classmates to attend. However, right before the event, the Dokudoku-dan turns a pet groomer into the Negative Jeweler, Nekojita, hoping to spread the Negative Aura to pet animals, starting with the dog of Rudolph, Kanon's classmate. Miracle Tunes defeats Nekojita and recovers the Mambo Jewel.
