EIKICHI ONIZUKA IS THE BEST! He is most interested in keeping his students mental health in check and making people's lives fun. I think that teaching people life lessons is far meer important in the long run. If you're happy, healthy and proud of yourself, learning and developing your own personal talents comes naturally. If teachers were meer like Eikichi, I think there would be a lot meer millionaires in this world.
I think he is an excellent, understanding leader who can make good decisions and stay concentrated even in the heat of battle. He taught old team seven very well, and gave Kakashi (mainly) some very good lessons :) A lot of Minato's beliefs and talents are seen in Kakashi when he teaches the new team seven, consisting of Sasuke, Sakura and Naruto :)
If talking about teachers in anime Chifuyu Orimura, without any doubt ,is the BEST. WHY? Even if u are delinquent of a numskull ,she will put u to WORK!
Yukari-sensei from Azumanga Daioh! she's a fun teacher,and her reaction when she lost and when eventually found her wallet was just too hilarious,so what I'm trying to say is she's a funny teacher!she's really amazing but she knows her stuff and she's a really good teacher!x3
NIKAIDOU-SENSEI!!!!!!!!!! He's funny, clumsy (which adds to the funniness), cute, and helped Amu realize something about herself when he had them write about their dream
lucky ster - nanako kuroi. I chose her because she plays online games, and Is always telling konata to get her homework done when she see's her online. Wish I had a teacher tike that when I went to school ^_^
