Hanae Sugimura is a blue- haired teacher with glasses.
She teaches in class 3-1, and she's often seen with the sports club, especially talking with the head Keishi Onozawa.
She greets me with "good morning". Then she tells me that I'm not in her class and I should be in mine, and not to run in corridors.
She will apprehend you if she sees you killing someone or dragging a corpse.
