Yuki unexpectedly enters the club room wielding a deck brush and demanding immediate cleaning. The group decides to convert the rooftop water storage tank into a swimming pool for the day. They carefully transfer the aquatic life from the tank into buckets to ensure the fish are safe. Afterward, they scrub away the algae and pond scum from the tank's interior. The girls relax and enjoy their new makeshift pool, letting their daily troubles fade away as they spend time together. This activity provides a refreshing break from their usual routine, allowing them to bond and unwind in a unique setting created by Yuki's spontaneous initiative.
