Megumi ends up ranking in the bottom two in her class and has to take a retest or else face after-school lessons for the rest of the school year, along with her classmate Kenta, who is more interested in baseball than studies. Megumi is put under further pressure when Blue threatens to suspend her from Pretty Cure activities should she fail her next test. Whilst Hime and Yuko help Megumi with her studies, Seiji teaches Kenta the importance of studying. On his way home to study, Kenta is targeted by Namakeruda, who creates a Baseball Saiark which Megumi challenges to a baseball match. After a series of foul balls, Megumi manages to figure out the pattern of the Saiark's pitches and land a home run, allowing her to defeat the Saiark. Afterwards, Megumi and Kenta study hard and manage to pass their retests.
