Attending the Summer Festival comedy show with the other Gosei Angels, Hyde cannot get the punch lines of an owarai duo to the others' dismay as they tell him to loosen up and enjoy the show. However, Moune and the others in the audience are captured by Hit of the Tengu. The Goseigers run after him as Gosei Knight arrives to fight the Yuumajuu. Upon learning that he has a Goseiger in his gourd, Hit decides to make the others laugh to make his job easier. Though the serious Gosei Blue and Gosei Knight fight him, the two are unable to work together as Hit tickles Gosei Pink and Gosei Black with his attack to suck them into the gourd before flying off. Gosei Knight decides to handle things by himself, angered that Gosei Blue got in his way. At the Amachi Astronomical Institute, Hyde sets a plan to make Alata laugh in order to draw Hit into a trap. After Alata attempts to give Hyde ideas by impersonating various comedians (such as Louis Yamada LIII), Hyde manages to laugh after hearing simple word puns, attracting Hit's attention. With Gosei Knight tracking him down to the fight with Gosei Red and Gosei Blue, Hit uses comedic flatulence to capture a laughing Gosei Red before he battles Gosei Blue and Gosei Knight once more. Gosei Blue gets an idea and talks Gosei Knight into defeating Hit with a word pun that forces Hit to destroy the gourd to save himself from being trapped within it. Becoming Super Gosei Blue with the other Goseigers, they and Gosei Knight defeat Hit with a Super Sky-Land-Sea/Knight Dynamic combo. When Hit enlarges, Gosei Ground holds him off so Seaick Gosei Great can disable him before Gosei Ground uses the GrounDrastic to destroy the Yuumajuu. Soon after thanking Gosei Knight for his help, Hyde makes himself laugh with his unintentional word pun, much to everyone's dismay.
