Prism Shine! Illuminate Your Heart

Synopsis

Working on a new picture book, Mashiro runs into Monda again in Sorashido Park. At Mashiro's request, Monda reads the work-in-progress, but when he realizes that she is trying to give a happy ending to a "fallen leaf" character he sees himself in, he grows angry, reveals himself as Battamonda, snatches the Mirage Pen, and leaves. Still wanting to talk to Battamonda, Mashiro meets him again at the park with Sora and the others, but Battamonda absorbs Undergu Energy. Even so, hearing Mashiro's words, he returns the Mirage Pen to her just before losing his own self. Sky and the others are pushed back by the powered-up Battamonda, but the Prism Shine unleashed by Prism illuminates Battamonda's heart and purifies him. Saved, Battamonda apologizes to Mashiro and slips away. Later, at the exhibition of the picture book contest, Mashiro's "Mr. Fallen Leaf" is on display as the grand prize work.
