Ready... Up! (S01E09)

Komichi has been appointed to lead a team in gathering supplies for the upcoming athletic festival. Over the weekend, she heads to a large mall with Erika, Touko, and Tomono. As a frequent visitor to the mall, Komichi is eager to show them around, but fashion-savvy Touko proves to know more about the stores. They stop by a bookstore, where Erika discovers a book by an author that Tomono admires. Having just finished reading it on the way to the mall, Tomono offers to lend it to Erika, only to realize that her bookmark is mysteriously missing.
