8. Muten Roshi from Dragon Ball
He might look like a weak perverted old man, but he is stronger than you could ever imagine. Although he put his student through rough training, they became like family.
This sensei even let his students hang out and even live with him well into their adult years. That’s dedication.
7. Genkai from Yu Yu Hakusho
Despite her age and her rather slight build, Genkai is not a teacher you would want to mess with.
Like Master Roshi above, she took a harsh hand with her students, but gave them the tools to survive in a brutal world. She imbued her students with great power, and while it seems like she didn’t love them, she would put her life on the line for them.
6. Nozumu Itoshiki from Sayonara Zetsubo Sensei
As a teacher full of despair and a history of multiple failed suicide attempts, you would think Nozomu would be a poor choice for a good teacher.
However, it is his despair that often brings light to his students as he teaches them to look at the world with a more critical eye.
5. Kumiko Yamaguchi from Gokusen
Good teacher by day and yakuza heir-apparent by night, Kumiko isn’t afraid to get a little tough with her students.
When you are teaching a classroom full of thugs, sometimes a little strength can go a long way to keep them in line and set them towards a more righteous path. After all, thugs often follow strength, and Kumiko has it in spades.
4. Junichirou Kagami from Ultimate Otaku Teacher
Although a certified genius, Junichirou spent much of his life as an otaku and NEET.
