Ms. Midori is smart and hard-working young teacher, and is protective of her students. She is modern and very open-minded. She is also very pro-AI, and gladly welcomed Astro into her class as her first ever robot student. When Midori was a child, she was chosen to thank the giant robot Jumbo at the first annual Robot Expo. Jumbo responded so kindly that it gave her a life-long love of robots, and she considered Jumbo a family friend ever since. She has two parents who are still alive, and it is implied she had a very normal and positive childhood.
