Idol × Warrior Miracle Tunes!

Unable to gather enough Harmony Energy to fight alone, Mai holds auditions to recruit idols to help. Kanon auditions and meets another contestant, Alice Kagurazaka. The Dokudoku-dan turns Alice's mother, Shizuko Kagurazaka, into the Negative Jeweler, Hysteris, and she is outraged when Alice fails the first audition. To rescue her, Kanon is summoned by Poppun and battles alongside Mai, recovering the Violin Jewel.

During the final auditions, Kanon is chosen to be part of Mai's new group, Miracle², along with dance prodigy Fuka. Fuka is not interested in becoming an idol warrior, but she joins when Okada, a teacher from her elementary school, is turned into the Negative Jeweler, Koegare. After defeating him, Miracle Tunes recovers the Piano Jewel.

Kanon and Fuka move into the dormitory, and Kanon begins her first day of school at Angie Private Academy. The crossing guard is turned into the Negative Jeweler, Katakotoyanen, and Miracle Tunes defeats her to recover the Samba Jewel. With their Harmony Energy charged, Miracle² records their song, "Catch Me!", to prepare for their debut.

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.

For Mother's Day, the girls decide to give their mother figures a flower bouquet. However, the florist has been turned into the Negative Jeweler, Tearegimi, who is spreading her Negative Aura through flowers. Miracle Tunes defeats her, recovering the Trumpet Jewel.

Miracle² films their first television appearance with popular child star Ryo on his cooking show, but when one of his fans turns into the Negative Jeweler, Kubittake, she begins to turn the rest of his fans against him, leaving Miracle Tunes to rescue him and recover the Flute Jewel.
