As Hime decides to hold a 'special party' at her house, Megumi shows up early with the intention of helping out with preparations. Hime, however, wants to prepare the cake she was making by herself, kicking Megumi and Ribbon out of the house when they try to help her out. As Megumi wonders what exactly she did wrong, Ribbon explains that Hime wanted to prepare the cake herself as a surprise for her. Meanwhile, Hosshiiwa targets a newlywed couple and creates a Wedding Cake Saiark, which Hime attempts to fight on her own, but ends up getting overwhelmed. Megumi arrives in time to protect her, with Megumi apologizing for not understanding her feelings and Hime apologising for getting mad at her. As the two desire to grow stronger together, they combine their strengths to bring forth a new power, the Twin Miracle Power Shoot, and defeat the Saiark. Afterwards, Hime decorates the cake Megumi and Ribbon worked on and holds the special party, celebrating 100 days since she became friends with Megumi.
Note: Cure Aqua celebrates the 10th anniversary. The opening features the second set of scenes from Pretty Cure All Stars New Stage 3 Eternal Friends.
