Be-Bop High School(2004)
It's a 2004 made for TV adaptation of the popular manga, not to be confused with the 1985 adaptation, which spawned 5 sequels. Be-Bop High School drops you into the middle of brawling rival high school gangs who do little else than chase each other around with knives and baseball bats. Using local yakuza ruffians as their role models, these high school hooligans pound themselves senseless as fawning girls adore them from the sidelines. Not much plot here; just a WHOLE LOTTA fighting!
