Class F works on a Chinese maid café for the school's cultural festival. At first, the plan works out okay, but soon the Tonkonatsu duo come along and accidentally eat one of the sample sesame balls, which were made by Himeji's terrible cooking skills. Accusing them of trying to kill them, Yūji uses "Persuasive Negotiations" in the forms of "Persuasive Negations using Fists", "Persuasive Negations using Kicks" and "Persuasive Negations using Wrestling", which drives away the duo. After their departure, business starts to fail. Minami's little sister arrives, promising to help. She tells them that while she was looking Akihisa, people tell her bad rumors about the Chinese cafe. Yūji deducts that the failure of their business is because the Tonkonatsu duo is spreading ill rumors about them. This is confirmed with a visit to class A's Maid Cafe, while watching the Tonkonatsu duo shouting out the rumors. Akihisa and Yūji hatch a plan to ruin the duo's image, (which involves Akihisa wearing a maid costume) and works greatly. The duo does not appreciate this, and kidnap Hideyoshi. Akihisa misinterprets and thinks they kidnapped Himeji and Minami. The Duo states that they are going to "have their fun with them". They then use Kōta's various hidden cameras and audio cameras to find the duo in the athletic's storage. Akihisa storms toward the storage still in the maid outfit, and punches the duo. He awkwardly finds Hideyoshi playing a board game(she also explains that Minami and Himeji are at the cafe). At the end of the day, their Chinese Cafe earns enough money to buy the equipment they want (with the help of Kōta and his "deluxe photo collection") , but they can only buy the equipment under one condition: they must win a Summoning Contest. Kōta announces the favorite maid of the day, and it was Akihisa. Both Himeji, Minami and Hideyoshi ponder over this, while Akihisa freaks out over the said results.

文月学园即将举办一场盛大的校庆，名为清凉祭。当每个班级都在努力准备时，唯有2年F班却玩起了棒球。一如往常被西村老师（铁人）责骂后，明久等人只好不甘愿地开始讨论要推出什么摊位。但是，当他们得知摊位收入可以直接用来改善班上的设备，每个人都感到相当欣喜。清凉祭当天，推出中式咖啡厅的F班却来了超难缠的客人……。
Ces OAV sont la suite de la première saison et un avant-goût de la deuxième. L'école Fumizaki se préparent à son festival. Chaque classe s'y prépare en collectant des fonds. La classe F, dernière de l'école, va s'investir et profiter de cette opportunité. Exceptionnellement, elle sera autorisée à acheter du matériel neuf avec l'argent récolté à condition de gagner le tournoi de créatures, qui aura lieu le deuxième jour du festival.
