3. Aikurou Mikisugi from Kill la Kill
The first impression of Mikisugi is a boring history teacher, but no one knowns that he is a cool secret agent. Despite, of all the troubles he is facing, Mikisugi is a cool and prefect teacher.
4. Negi Springfield from Mahou Sensei Negima
Not all the teachers have to be old enough to be the teacher. Some teacher are young enough also.one such example is Negi who is only 10 years old. Despite of all the complications, he has to face the greatest challenge in form of flirty girls. It is his positive attitude and his use of magic that makes him the best teacher for the audience as well.
