About
Kagami Junichirou was known as a physics genius when he was a teenager, and he was even published in "Nature." However, after college, he suddenly lost all interest in science. As a NEET, he's devoted himself to his anime blog and nerdy collecting habits. He claims he has a serious illness called "I can't do anything I don't want to do." Desperate to get him to do something with his life, his little sister manages to get him a job teaching physics at his old high school. He's certainly an unconventional teacher, but he becomes fairly popular with the students. After helping a girl who's being ruthlessly bullied, Kagami finds that he actually likes teaching. Will he continue his career as a weird teacher? Will he go back into physics? Or will he end up back where he started?

Season 1
I'm a High School Teacher Now
Junichiro Kagami's sister forces him to take on a real job, as a high school teacher. He uses his genius intellect to keep himself satisfied with his job. One day, he notices that one of his students is not getting along with her classmates.
Laws of Society
It turns out that teaching is not Junichiro Kagami's true calling after all. With motivation at rock-bottom, he manages to survive for one month, a feat that demands celebration. But during his visit to Akihabara, Junichiro witnesses something.
Chase in Akihabara
A mysterious young woman offers to recruit Junichiro Kagami as a teacher at her school. Junichiro, unwilling to let go of his freedom, escapes to his natural Otaku habitat, the town of Akihabara. The chase is on!
Dignity of Maids
For Junichiro's first lecture, he attempts to change the views of stubborn Makina Momozono, Koyomi's right-hand girl. What does it mean to have dignity as a maid in an Akihabara-style Maid Cafe?
Monster of Icho Academy
Junichiro's next student is Seijuro Nanami, a monstrously strong former baseball player turned violent delinquent. With the help of a familiar face, Junichiro must earn the respect of the Monster of Icho Academy.
An Amusing View
Junichiro faces off against Seijuro "Cyborg Human" Nanami in a game of soccer. Forcing Seijuro to play with the odds stacked heavily against him, Junichiro's victory seems certain. However, Junichiro's schemes are never what they seem.
A Beautiful Girl's Secret
If you're born with something that some people poke fun of, would you hide it away, or show it off as part of your identity? Kanan Chinami swears to hide her characteristic voice for the rest of her life, but Junichiro has other plans for her.
The Truant is a Grand Master
Who needs school if you have a career? Who needs friends when you have thousands of loyal fans? Sachiko Tanaka is too busy for school, and Junichiro would normally agree. Will he find a way to get her to come to school? Will he even try?
