The three female high school student members of the manzai (stand-up comedy) trio Young Wai-Wai—Sakamoto Yayoi, Takahashi Yomogi, and Hosono Yuzu—have beaten the local qualifiers and are one step closer to participating in the main Teppen Grand Prix comedy competition. As a final trial, the girls must live together with the members of four other comedy teams in Takako-so, a dormitory with a distinguished history of housing famous comedians. Will the girls be able to complete the various tasks assigned to them by Seiji, the dormitory manager, and fulfill the final requirements to compete on stage?

One day, between their rehearsals and training activities, the five comedy teams at Takako-so are given a chance to appear on television. Only two teams are allowed, so the girls hold a lottery to decide who will go. The winners are Bullet Kunoichi, with members representing two parts of the western Kansai region, and Akudare Kingdom, with members from the eastern Kanto region. When the two teams arrive at the shooting location, they realize something strange is going on. A quirky producer suddenly appears on the unusual set and has the girls start competing in a bizarre quiz program.

The Takako-so residents get mislead by a string of clickbait articles with headlines like "Famous Mascot Complains to Store," "Cows Pile on Hokkaido Cookie Shop," and "Full-Scale War Breaks Out Between Takoyaki and Okonomiyaki." Meanwhile, Shirakabe Mako from Celebri-Tea struggles to do work on a frozen laptop in the cafeteria. When Yuzu offers to fix Mako's computer, what pops up on screen is a document written by White Wall, the author of all the clickbait articles.

The three Invaders return to their home prefecture of Hokkaido for a required summer school day. On the bus ride to school, Mone starts talking about Hokkaido's seven folk legends while Chihori shares random facts about space. As Yuina responds to the girls' wacky conversation with her usual comical comebacks, she is overcome with a very strange feeling about the situation.

With manager Seiji out of town for a bodybuilding competition, the girls of Takako-so try to figure out how to take care of household chores themselves.
