The main character of the series, originally just another above-average student until he decided to enroll at Cromartie. Everyone else at Cromartie assumes that he's the toughest kid in school, since a rabbit would never go into a den of lions (unless it was a really badass rabbit). He has ambitions to change the school for the sake of bettering its student body.

Is this the real life? Is this just fantasy? 
 
The only thing for certain is that for Kamiyama, Cromartie High School is his reality. And what a surreal reality it is. 
 
Because this is where the toughest, meanest (and often dumbest) students are sent to do time. At Cromartie, purple-mohawked bruisers and pencil-chomping street thugs are just part of every day life. And so is a 400-pound gorilla. And a macho brute named Freddie who travels with his own theme music. And, of course, Mechazawa, the student voted most likely to need an oil change. So pack your bags, put on your best tough-guy swagger, and get a lesson in insanity from the hilarious losers at Cromartie High. This is one class you won't ever want to cut.

Welcome to Cromartie High&mdash;a melting pot of underachievers and overzealous bullies, where the fist rules and the student body has the combined I.Q. of a rusty nail. After a whole lot of bad judgment and a little bad luck, Takashi Kamiyama is now attending this academy of dunces. Here, his only homework will be defending himself against the foul-mouthed robots, semi-intelligent apes and masked villains that roam the halls of Cromartie High School!
