As the school sports festival approaches, Tatsuko from class 5-1 suggests a new 'Eel Scooping' event, which doesn't sit well with Suzuka. Meanwhile, Illya informs Miyu about the main dance event that comes with a tempting prize but requires rigorous preparation. The group of friends, including the sarcastic Nanaki, composed Suzuka, enthusiastic Tatsuko, lively Illya, timid Mimi, and reserved yet skilled Miyu, set out to claim victory in the dance competition to uphold their class's reputation and support their teacher, Taiga Fujimura, who they mistakenly believe is involved in a high-stakes wager they must win.
