Noriko Kashiwagi

Noriko Kashiwagi (柏木 典子 Kashiwagi Noriko) replaces Morooka as Class 2-2's homeroom teacher after he is killed, and she is also the biology teacher for Yasogami High. She flirts with her students, or, to the least, tries to grab their attention. Even though her personality is the polar opposite of Morooka's, she is greatly hated by the students of 2-2.
