Kunigaoka holds a school festival in which all the classes are competing to make the most money with their stalls. As Gakushu and the rest of A Class use business connections and idols to draw in customers, E Class takes advantage of their mountain location by using local ingredients to create natural tasting dishes that prove a hit with visitors. As many familiar faces show up to E Class' restaurant, Nagisa is forced to crossdress again when Yuji, the boy from the island resort, comes to visit him while still under the presumption that he is a girl. Although Nagisa ultimately reveals his true gender, Yuji, impressed by his honesty, posts about the restaurant on his world famous food blog, causing a gigantic influx of customers the next day. On the advice of Koro-sensei, E Class eventually close their stall early to avoid disrupting the mountain's ecosystem with excessive foraging, after Hiromi arrives to patch things up with Nagisa. Meanwhile, the reputation of E Class, having come in third behind the A Class and High school class in spite of closing early, begins to show marked signs of improvement among students on the main campus.
