A lively group of six high school girls, with colourful personalities, tries to master their daily life at school: there is the gifted 10-year-old Chiyo, the carefree klutz Ayumu, the shy but kind Sakaki, the mischievous Tomo, the short-tempered glasses-wearing Koyomi, and the extroverted tomboy Kagura. Together with their quirky teachers Kurosawa Minamo and Tanizaki Yukari not a day passes without some minor incident occurring.
