Prism Shine! Light Up Your Heart! While working on her new picture book at Sorashido Park, Mashiro meets Monda again and shows him her work, only for him to get angry at her due to their differing opinions. After he reveals his true identity as Battamonda to her, Skearhead appears before him and offers him a final chance to defeat the Cures by using Underg Energy, although it will cost him his soul in the process. When he attacks the Cures, Mashiro is able to purify him with her new technique, Prism Shine.
