Based on the four-panel comic strip that follows the lives of a group of high school students, this animated short features a compilation of comedic vignettes during a typical day in class. The girls compare their test results, child prodigy Chiyo demonstrates her inability to perform tongue-twisters. The stoic Sakaki broods over her earlier encounter with Kamineko, a cat which delights in biting her hand, and daydreamer Osaka imagines what would happen if Chiyo lost her pigtails.
