Reiko Terajima

Reiko Terajima is a chemistry teacher at Katagiri High School and the homeroom teacher of class 3-1. Described as "kind, but strict", Reiko is gentle and caring around her students and the other teachers. She can also be a little lenient with her students, accepting Izumi Miyamura's explanation of his pierced ears without putting up much resistance. However, when dealing with Shin Yasuda, her personality completely changes, and she is hostile towards him.
