Hinata shows the girls a magazine article about a Cafe in the next town and asks if they want to go. However, the article also shows a secluded lake nearby which gets Asumi's attention. Nodoka decides that should visit the lake as it's Asumi's first outing. At the lake the girls meet an arborist named Sakuya Itsuki, who tells them all about the work she does with nature, impressing Asumi. That night, Daruizen uses a Mega Part on a bird the girls rescued earlier to create a new general. The next day Rate senses the lake is in trouble and Asumi manages to create a portal to transport everyone back there. The girls find Sakuya unconscious and the new general, Nebusoku, infecting the lake and the surrounding forest. The girls transform and manage to use Nebusoku's fear of flying to defeat him, with Cure Earth purifying him.
