Reiko Terajima

Reiko Terajima is a chemistry teacher at Katagiri High School and the homeroom teacher of class 3-1. Reiko has shoulder-length brown hair that is either styled in a small ponytail or loose. She is almost always wearing a white lab coat. 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.
