Ultimate Utako Teacher S01-EP1 "I'm a High School Teacher Now"

Famous scientist, Junichiro Kagami, claims he cannot get a job as he has YD, an illness where he can only focus on what he "Yearns to Do", meaning he spends all day obsessively writing on his blog about anime and manga. His sister Suzune Kagami forces him to become a part time teacher at Higashi Shinmei High School. Junichiro meets student Minako Kano who is being bullied by Miho Kito and her former friends. Junichiro has the class play a computer game and observes how they play to learn about their personalities. While talking to Minako about her bullies he reveals he became famous after he designed a theoretical Anywhere Door in high school that cannot be built until the 22nd century. Junichiro later saves Minako from a molester after Miho puts her personal information on the schools underground website. The bullying gets worse as Miho tricks Minako into drinking juice mixed with chalk dust. To teach the bullies a lesson Jun'ichiro convinces them he has published all their information on the underground website when in reality he was just trolling them from a fake website. Jun'ichiro is being watched by someone from the shadows.
