This is a list of characters from the manga series Azumanga Daioh by Kiyohiko Azuma, later adapted to anime.
Azumanga Daioh chronicles the everyday life in an unnamed Japanese high school of six girls and two of their teachers: child prodigy Chiyo Mihama and her struggle to fit in with girls five years older; reserved Sakaki and her obsession with cute animals while certain ones seem to hate her; spacey Ayumu "Osaka" Kasuga with a skewed perspective on the world; Koyomi "Yomi" Mizuhara's aggravation at an annoying best friend; Tomo Takino, whose energy is rivaled only by her lack of sense; sporty Kagura and her one-sided athletics rivalry with Sakaki; their homeroom teacher Yukari Tanizaki; and her friend, physical education teacher Minamo "Nyamo" Kurosawa. Secondary characters include Kimura, a creepy male teacher with an obsession with teenage girls, and Kaorin, a female classmate with a crush on Sakaki.
Four of the girls were included in Newtype's top 100 anime heroines of 2002: Osaka was awarded 7th, Chiyo 11th, Sakaki 21st, and Yomi 78th. Together they made Azumanga Daioh the 2nd most popular series of 2002 for female characters.[1]
