Tokyo Metropolitan Cromartie High School is a highly feared high school and surprisingly full of idiots that has been dubbed "the big league of bad guys" with a selection of delinquents. Takashi Kamiyama, is an honor student, but in order to go to the same high school as his best friend who helped him in high school, he took the entrance exam for Cromartie High School, so Kamiyama ended up entering the school alone.
