Yuki is practically bouncing off the walls after coming up with an idea to take a field trip outside the school grounds. Rii-san and Kurumi remind her that club members aren't supposed to leave the grounds, but Yuki's convinced that if it's a school-sponsored activity they won't be breaking the rules. Their destination: the mall! Take a stroll down memory lane, to the days before the group first met Mii-kun.

Yuki and the gang begin their "field trip" to a mall on the outskirts of town. While raiding the supermarket on the basement for supplies, Kurumi chances upon a puppy... None other than the School Living Club's future mascot, Taromaru! He happily joins the girls as they make their way to the fifth floor, where Mii-kun remains hunkered down.
