Azumanga Daioh: Minamo Kurosawa

A gym teacher at the girls' school. In the girls' first year of high school, she is the homeroom teacher of Class 5. During their last two years, she is the homeroom teacher of Class 2. An old high school friend and rival of Yukari, they have a juvenile, exasperating, but funny relationship with each other; Yukari relentlessly insults and freeloads from Nyamo, but Nyamo gets her digs in, too. "Nyamo" is a nickname from her student days, but Yukari calls her that, and so does Tomo. Other students call her Kurosawa-sensei. Whereas Yukari appears to be an older version of Tomo, Nyamo resembles Yomi (more in personality than looks) and the two teachers' odd relationship is similar to the one that Tomo and Yomi share.
