Osaka evaluates her past rural and present urban lifestyles. She is told by Koyomi "Yomi" Mizuhara that Chiyo is highly gifted and talented. Osaka is oblivious to the chaos around her in the classroom caused by a cockroach, being focused on eye floaters instead. She shows her lack of physical fitness in physical education, unable to sprint in track and field and unable to execute an overhand pass in volleyball. After eating spicy food, Osaka develops hiccups, which Chiyo, Tomo, Yomi, and Sakaki try to get rid of using traditional and foolish methods. Osaka ends up transferring her hiccups to Chiyo. She then plays on a Japanese idiom between "the grain of truth" and "the truth about grain". She later unknowingly daydreams about Chiyo's theoretically detachable pigtails during class, soon being caught by Yukari nonetheless.
