With only three days left at Takako-so, the fifteen comedians are given one final test. Seiji orders them to stay inside the dormitory for three full days, no matter what happens. It sounds like a simple task at first, but Seiji also calls on some unusual visitors to challenge the girls' confidence as budding comedians and entertainers. Despite having already overcome so many trials, the five teams must put their sense of humor on the line one last time to face their biggest battle yet.
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.
