After a health checkup reveals that Centorea, Meroune and Miia have gained weight during their homestay, Smith directs the group to trial a newly established, "liminal friendly" gymnasium called Sports Club Kobold run by the eternally enthusiastic Kobold, Polt.
Upon their arrival, Polt has the girls try out various exercise equipment only to discover that none are appropriate due to their differing body shapes. Directed to the pool, Miia and Meroune engage each other in a race with the prize being that they are allowed to do anything they want to Kimihito.
While the girls use their attributes to the fullest in an attempt to win, the state of the pool water (cold and chlorinated) starts causing them pain but they still persist in the race. After Kimihito admonishes the girls for putting themselves through pain when they were supposed to be improving their health, it is revealed that Centorea had actually won the race and she spends the rest of the day holding hands with Kimihito.
