The Birth of Idol Warriors, 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.
