There are some definite similarities. Shiritsu Bakaleya Koukou is kind of like Gokusen-lite, with ten times the girls and no teacher making speeches and kicking butts. There's a lot of fighting (but these guys don't seem to get pounded into the ground like the guys from Gokusen do). And a lot of running. And a lot of ragegrowling from a lot of cute guys. There are even similar themes - fighting for what's important, loyalty. Plus, Takaki Yuya from Gokusen 3 is in it. If you enjoyed these things about Gokusen, give it a shot, the episodes are only about 20 minutes.
