For the members of Miss Yukari's English Class, a typical day may be just a little unusual. Part of that's due to Miss Yukari herself, whose teaching style (and personal ethics) tend to be odd, improvisational and spontaneous, but her students are just as unconventional: There's 10-year-old Chiyo, still at the top of her class after skipping five grades, and her opposite Ayumu "Osaka" Kasuga, whose poor grades are surpassed only by her horrific skill at sports. Then there's Tomo, a competitive slacker who puts excessive energy into doing very little, and Koyomi, whose surprising maturity is compromised by a malevolent sense of humor. Tall, statuesque Sakaki's athletic exterior hides both unexpected shyness and a most unfortunate obsession with cats, while tiny Kaori's heart is mainly obsessed with Sakaki. They may all seem like perfectly normal girls on the outside, but even their most mundane activities magically become the most extraordinary adventures as they learn all about life, the universe and affairs of the heart in AZUMANGA DAIOH!
