Ten-year-old child prodigy Chiyo Mihama is struggling to fit in at high school with girls five years her senior: Osaka (dimwitted with a quirky perspective on the world), Tomo (a powder keg ready to explode at any moment), Kagura (the competitive athlete of the group), Yomi (the hothead), and Sakaki (shy and obsessed with animals that don't return her affection). Together with their teacher, they navigate the challenges and fun of high school.
