Nachdem die Mädchen über ihre gescheiterte Vorführung beim Supermarkt-Event hinweggekommen sind, richten sie ihren Blick auf das Hanairo-Yosakoi-Festival. Derweil verkündet Machi zum Schock aller, dass der Yosakoi-Club noch immer nicht offiziell als Club anerkannt wurde.
Yaya and the others manage to encourage Naru to finish the performance, but shortly afterwards, Hana collapses. After Hana makes a full recovery after a few days, Naru still feels guilty for letting her fear of an audience ruin the performance, but is encouraged by her friends to keep trying. Later, the group learn from Machi that their club is in danger of being shut down at the end of the term since, as a substitute teacher, Sally can't be an official advisor. As the girls try to think of a way to keep Sally as their advisor, Machi feels hostility towards Sally, who left home when she got tired of trying to live up to her parents' expectations. The next day, as the girls hear rumor that Sally may be quitting as a teacher, Machi assumes she is abandoning them just like she allegedly did with her and badmouthes her. After some stubbornness, Machi eventually learns from Tami that Sally was actually applying to become a full-time teacher, stating that it was Machi who inspired her to become a teacher. Upon hearing this, Machi apologises to Sally, who manages to pass her exam, and contemplates joining the yosakoi club herself.
