S3 for me was the perfect 'end' to the Gokusen series. It seems that Yankumi's way of teaching has finally been accepted , and she manages to not get fired for once in her life time, and surprisingly her yakuza background never came to light either.

Sawatari really deserves some applause for his character development, and Kuma is literally the perfect role model for Yankumi's current students.

What shocked me the most, is that things really did escalate more than they did in s1 and s2, and I love the freshness it brings. Mind you, I do sometimes skip over Yankumi's speeches as she usually utters the same words pretty much everytime, but I gotta admit that her fighting skills seems to be much better since s1.
