1, "A Child High School Student" We first meet 10-year-old prodigy Chiyo Mihama on her first day of high school. Meanwhile, English teacher Yukari-sensei is also on her way to school, and nothing seems to be going her way. 2, "A Genius" We learn that, in spite of being very smart for her age, Chiyo is far from perfect. Nonetheless, Chiyo quickly becomes a featured member of the class. 3, "Scary, maybe?" Chiyo is helping out in class when she meets Miss Sakaki, the tall quiet girl that everyone idolizes. But, upon reviewing Sakaki's pick of career choices, Chiyo wonders if their might be more to Miss Sakaki than meets the eye. 4, "The Rampaging Tomo-chan!" We meet Tomo, the hyperactive girl, as she challenges both Sakaki and Chiyo and generally gets herself into trouble. 5, "An Osakan Girl" A new transfer student, Ayumu, arrives from Osaka. Now, poor Ayumu must try to deal with her classmates' preconceived notions about Osaka natives.
