Sumirei Ando

She wears contemporary horn-rimmed glasses, and a considerable amount of makeup. She is considered the school's bossiest teacher and frequently gets angry at the children. When she gets mad (like if some one calls her old) her makeup cracks off her face prompting her to reapply it quickly, usually after a child comments that her "real face is showing." She also has a crush on Zenjiro, and is quite fond of the limbo. While mean, she's stated that the real reason she became a teacher was to make children happy, but she began worrying about losing face with the students and started worrying more about discipline.
