Ultimate Otaku Teacher

Kagami Junichirou was known as a physics genius as 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 known as the "Don't Care Syndrome". 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?

Denpa Kyoushi (Ultimate Otaku Teacher) is a weekly manga series by Takeshi Azuma about a 22-year-old Otaku who reluctantly becomes a teacher. It seems to be inspired by Great Teacher Onizuka, but instead the main lead handles problematic students the Badass Bookworm way, unlike Onizuka's notoriously rough but nonetheless awesome tactics. Nonetheless, it still has the same theme and spirit as GTO.

Not to be confused with Ultimate Teacher - if you value your sanity.


 * Absurdly Powerful Student Council President: Makina Momozono acts as the school chairman's right-hand man and thus can decide whether a student or teacher stays or leaves the school. Until Kagami came along, that is.
 * The Ace: Kagami as a teenager, and his younger sister Suzune.
 * Alpha Bitch: Miho Kitou. She got better.
 * Anime Hair: Kagami has a rather outrageous quiff. So does Nanami, albeit lighter.
 * Badass Bookworm: Kagami is so good at Science that he was able to prove a scientific theory without breaking a sweat when the best scientists in the world have trouble disproving it. And yet he doesn't fear monsters like Seijuurou Nanami and can take punches to the face and being whacked by a baseball bat on an everyday basis. Bad. Ass.
 * Berserk Button: Makina hates people violating school rules.
 * Never diss Anime in front of Kagami. Also, don't let Suzune know you're an Otaku, unless you're a mangaka.
 * Born Winner: Kanan Chinami is born with a 2.5D voice, which is said to be the ideal voice for anime seiyuus. She did not take this too happily at first, though. But with Kagami's encouragement, she decides to become the official voice mascot of Hiiragi Private Academy.
 * Bunny Ears Lawyer: Despite being an insufferable Otaku, Kagami is a certified genius and is so good at science and technology that even CERM wants to seriously hire him.
 * The Chessmaster: Chairman Hiiragi.
 * Cloudcuckoolander: Again, Chairman Hiiragi.
 * Composite Character: Kagami is said to be one of the Great Teacher Onizuka and The God of Conquest.
 * Cute Mute: Kanan prefers to communicate through e-mails because she thinks people are more interested of her voice than herself. She got better, though.
 * Delinquents: Minako Kanou used to be part of Miho's Girl Posse, until a sympathetic person from the Internet inspired her to become a hero.  This is how Minako came to know about Nanami, by the way.
 * Desperately Looking for a Purpose In Life: Initially, Kagami was forced by her sister to become a teacher to get him out of his NEET status, then was sacked barely a month after he started, then got offered a job for CERM, then got hired by an eccentric school chairman, then gladly accepts an offer from an old classmate of his after getting talked out of teaching by the CERM representative who came to his house earlier. Apparently, it is difficult for a Hard Core Otaku to get a life.

 * Meido: Kiriko works part-time as one, which Makina uses as a ground to expel her from the school. Cue Kagami dragging Makina into a Meido on-the-job training so that she stops looking down on them.
 * Morality Pet: Minako for Nanami, and she knows it.
 * The Nicknamer: Kagami can make up a nickname for anyone he meets almost instantly, such as "Bitch Slap or Face Punch" for Minako, "Spice Girls" for Miho, "Fries" for Kiriko, "Roboman" for Nanami, "Irregular Twin Tails" for Makina, and "Anime Girl" for Kanan.
 * Older Than They Look: Koyomi Hiiragi, School Chairman of Hiiragi Private Academy; and Minami Kitayama, the 17-year-old manager of the Maid Cafe Kiriko works at who looks and acts five years younger. Of course, it is perfectly possible that Minami is a member of the Forever 17 club and has availed herself of Academy City's latest technology to keep herself younger-looking.
 * Paper Fan of Doom: Again, Chairman Hiiragi.

 * Chapter 16's To Aru Meido no Tsunde Lesson and "Sogebu!"
 * CERM teleport experiments, microwave ovens and bananas, otaku physic geniuses drinking Dr. Peter, tutturu... it sounds vaguely familiar.
