While undergoing physical examinations, which include bust-waist-hip measurements, most of the girls find out they have been gaining weight, but they can't go out to exercise without Kimihito. Smith sends Kimihito and the girls to a gym suited for Monster Girls, owned and run by a kobold named Polt. She takes everyone on a tour of the brand-new facility, but finds out that not everyone is suited to or able to use the exercise equipment. A visit to the gym's oversized pool leads to a race between Miia and Mero, with Kimihito as the Grand Prize.

One morning, the daughter of Rachnera's previous host family, Ren Kunanzuki, shows up with a petition for Rachnera to return to them. However, Ren is quite obsessed with her stubborn attitude that taking in Rachnera constitutes a trial for her patience and capability; and her encounters with Kimihito's other housemates only serve to strengthen her opinion until Kimihito finally returns home. In a post-credit skit, Miia persuades her fellow housemates and the girls of MON to try on new bras and pantyhose she has purchased for them all.
