Gokusen Season 3 (2008)

Sinopsis

Sawatari Goro now works at Akado High School as a vice principal. Although the head director of the school board specifically orders him to handle the problematic class 3-D, the students are just too much for him. So Sawatari goes far away to a southern island to search for Yankumi and convince her to work for Akado. Yankumi accepts the offer, only to find that her class (again) is full of punks, where two rival groups of students are always at each other's throats. Will Yankumi's strong belief in students and teaching work this time? (Source: MyDramaList) ~~ Adapted from the manga “Gokusen” (ごくせん) by Morimoto Kozueko (森本梢子).
