Ultimate Otaku Teacher (Original Japanese Version)

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.

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.

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!

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?

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.

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.

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.

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?

Junichiro and his in-game partner Luce have completed almost every quest in the popular MMO Uroboros. Just one quest remains - the one that requires a large party. Junichiro convinces the students to join, but realizes he needs one more.

Koutaro Araki, the class truant also known as Luce, teaches his classmates how to play Uroboros. The team rapidly becomes competition-ready. However, will Koutaro be able to face his fears and stand side by side with his classmates?

Seijuro, Kisaki, and Makina each find out about Koutaro's true identity. Koutaro seems to be steadily getting closer to returning to school, but as always, Junichiro seems to have other plans.

Junichiro organizes a party to celebrate the victory of Team 23. He invites a surprise guest - Koutaro's former classmates - and challenges Koutaro to a fight. Koutaro must survive a hopelessly uphill battle to keep his secret.
