Ultimate Otaku Teacher (Japanese: 電波教師, Hepburn: Denpa Kyōshi, lit.

It was serialized in Shogakukan's Weekly Shōnen Sunday magazine from November 2011 to March 2017, with its chapters collected in 26 tankōbon volumes.

The story follows Junichiro Kagami, whose sister Suzune is angry at him because of his complete disinterest in the real world.

As Junichiro is interested in nothing but anime, manga and games, Suzune forces him to go on a job as a physics teacher substitute at the same high school from which he graduated.

Junichiro proves himself a capable and hardworking teacher who comes with unorthodox methods based on the seemingly useless knowledge he obtained as an otaku to teach and motivate his students.
