The Almighty Otaku Teacher
Ultimate Otaku Teacher (Denpa Kyoushi note ) is a shonen manga series by Takeshi Azuma, which was serialized in Weekly Shonen Sunday from 2011 to 2017 and compiled into 26 volumes.
Junichirou Kagami is a 22-year-old Otaku who has no interest in the real world and buries himself in anime, manga and video games. Frustrated with his lack of ambition, his younger sister Suzune forces him to get a job as a teacher at his old high school. Though Junichirou is reluctant at first, he soon proves to be surprisingly capable at his new job, using unorthodox methods from his otaku knowledge to motivate his students.
The manga has an anime adaptation by A-1 Pictures which aired as part of the spring 2015 anime lineup, and ran for 24 episodes.
Tropes in Ultimate Otaku Teacher include:
- Anime Hair: Kagami has a rather outrageous quiff. So does Nanami, albeit lighter.
- 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.
- Brother–Sister Incest: It's strongly implied a few times that Kagami's sister likes him this way. For the most part, this seems one-sided.
- Demoted to Extra: More or less with everyone with an introduction arc devoted to them. After their initial arc, they don't have nearly as much screen time as they once did. Justified since the manga is already building up a large cast.
- Gender Bender: In the battle against Subaru's team to determine whether Kagami and Subarunote would become lovers or not, the chosen game is a Magical Girl virtual game simulator, where the game avatars are all...well, magical girls. This means that male players still get female avatars, which means that Kagami, Nanami and Fuwa all get bent. It's the return of Kagamin!
- Improbable Age: According to Kagami, Minami was once an exchange student in a Maid Academy in England, and she's now 17 years old. How the hell did that happen?!
- Improbably Female Cast: The female-to-male ratio is quite largely in favor of the females regarding the characters that surround Junichirou. However, it does start to even out by the time of the SS group war where many of the main campus students introduced are male.
- King Incognito: Chairman Hiiragi poses as a manga shoplifter in search for potential teachers for her school.
- The Little Shop That Wasn't There Yesterday: In her attempt to place herself at the top 10 of Incho Academy, Kanan stumbled across the home tutor service which claims to have helped a lot of students ace their exams and subscribed to it. Turns out that the legendary tutor was actually Kagami.
- 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.
- Nice Job Breaking It, Hero: Kagami's Routine Breaker program allows ever student to pass ever test given to them so they can focus on what they want to do, however he didn't consider the effect it would have on students that don't know or don't have anything in particular they want to do. This is the case Tachibana who ends up Driven to Suicide as a result.
- The Nicknamer: Kagami can make up a nickname for anyone he meets almost instantly, such as "Bitch Slap or Face Punch" for Minako, "Spice Girl" for Miho, "Fries" for Kiriko, "Roboman" for Nanami, "Irregular Twintails" for Makina, "Options" for Chairman Hiiragi, and "Anime Girl" for Kanan.
- Not What It Looks Like: When Minako and Kagami reunite, she cries about him not taking responsibility and quitting school over one of the most significant moments of her life. Right in front of his sister.
- 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.
- Playful Hacker: Kagami as a result of being a hardcore otaku. He created a chatroom which has defenses comparable to that of the Pentagon(!), a home tutor service which have helped a lot of students ace their exams, and his very own MMORPG!
- Red Baron: Kiriko Shikishima the "Cutter Girl" and Seijuurou Nanami the Monster of Hiiragi Private Academy.
- Shout-Out
- Kagami's lifelong dream is to create a Dokodemo Door.
- In Chapter 12, a student wonders if Kagami was "the Great Teacher Onizuka" since he tamed "that monster Seijuurou Nanami".
- Chapter 16's To Aru Meido no Tsunde Lesson and "Sogebu!" note
- CERM teleport experiments, microwave ovens and bananas, otaku physic geniuses drinking Dr. Peter, tutturu... it sounds vaguely familiar.
- Chapter 51 features the "I will be your eyes" scene from a certain fantasy manga.
- The end of Episode 17 has Kagami and Koutaro playing a video game similar to Capcom's Commando (Capcom), complete with Capcom sounding music from their old arcade games from the 80s.
- Teacher/Student Romance:
- It gets brought up from time to time that Kiriko and Kanan have feelings for him, most clearly during the Madoka arc. He also seems to unintentionally be gaining a harem with at least three girls so far - but this is also very much on the back burner.
- Kotarou also seems to have feelings for him, quite possibly the most extreme.
- Wholesome Crossdresser: Kotarou. He looks so much like a girl, the chairman banned him from wearing the male uniform.
- Wide-Eyed Idealist: Chairman Hiiragi dreams of an interesting country of Japan, and the vision she sets for her school is to turn students into wacky yet well-adjusted students.
- Write Who You Know: In-Universe, Sachiko's usual MO when writing manga. Hilarity Ensued when she applied this trope to pretty much anyone, but ended up in a rather spectacular failure.
