Our Hearts Are Together! The Sunlight That Shines on the PreCure!.The girls all go to the beach, where Towa seems to be insistent on doing activities other than swimming. Unable to tell the others that she can't swim, Towa is joined by Yui, who expresses how envious she is of her being able to help everyone, but still feels content with being with everyone. Just then, Lock appears and targets Yui to create a Sketchbook Zetsuborg to attack Towa, while also sending clones of himself to attack the other Cures. Understanding the importance of being around everyone, Towa manages to defeat the Zetsuborg and rescue Yui, whose notebook brings forth a new Dress-Up Key, the Sun Key. Later that night, Haruka and the others are shocked to discover that Lock had managed to steal all of their Dress-up Keys during their fight.
