Def Reika Kitami

 

[MoonlightShadow]

That would be Onizuka

 

[Rinko]

I would go with Korosensei
He is from the assassination classroom anime and I like the way he teaches them everything.

 

[Star_Of_Hope]

I am not sure.
All the characters mentioned above are great. I would like to add Eight tails from Naruto to this list.
