Tamae Okamine (岡峰 珠恵, Okamine Tamae?) is a homeroom teacher for Shido's class. Her students usually called her by her nickname, Tama-chan, due to her younger appearance. As she is 29 years old and still single, she is very anxious to get married. Despite being in her late 20's, Tamae has a much younger appearance (due to her childish face), with a small body build while wearing thin-rimmed glasses. She is 150 cm tall, as stated in the anime, and has light brown middle length hair.
