As the only comedian trio unable to pass Seiji's final test, the girls of Young Wai-Wai look back on their hilarious days at Takako-so with a mix of fondness and bitter regret. Then, seemingly out of nowhere, Yuzu's housekeeper Steward appears and lightens the mood with a message from Seiji about a comeback round. Thrilled to learn that they still have one last chance, the girls start preparing their final comedy routine with the encouragement and support of their Takako-so friends.
Yayoi Sakamoto, a diehard fan of comedians and comedy acts, enrolls in the private Kazuki High School in Nanba (Osaka's entertainment district famous as the starting point for many comedians). She reunites with Yomogi Takahashi, a childhood friend who once formed the comedy duo "Konamonzu" with her when they were little. Before long, they find themselves putting together a routine at a park like they did before, in order to enter a local shopping area's contest. At that moment, a mysterious girl calls out to them.
