I Want to Become Popular / First Errand / Idol Activities (S01E03)

Akane is tasked with grocery shopping, and Hikari eagerly offers to join her. As Akane attempts to avoid being seen by security cameras, Hikari ages herself into an adult to help a stray cat trapped in a tree. However, this leads to her clothes no longer fitting, prompting her to turn Akane into a child so they can swap outfits. The cat Hikari saves is later adopted by the Sakurada family and named Borscht. In the following week, Teru steps in to handle Akane's shopping, with Shiori tagging along to keep him out of trouble. Throughout their outing, Shiori frequently uses her powers to tackle the various challenges they face.
