Idol × Warrior Miracle Tunes! S01 E28 Farewell, Dokudoku-dan! A New Enemy Appears

With Sano and Uno serving the Demon King, the Dokudoku-dan doubt their worth and leave. Miracle² finds a Negative Aura reading from an underground mall and are led to an old man (Tomio Suga), who transforms into the Super Negative Jeweler, Jinzo. He easily overpowers Akari and Hikari, but Mai uses her power to deflect his attack. Miracle Tunes uses the Rock Jewel to defeat him, recovering Mai's Crystal Jewel.
