One of the most notorious delinquents of Cromartie. Though he is a robot, no one but the main characters seems to notice, including himself. Other delinquents rely on him and he gives good advice.   Mechazawa is bad with machines: "Why are you bringing ME your electronics? I want to help you guys in any way I can -- even if I gotta put my life on the line! But when it comes to MACHINES, I'm helpless myself."  From the character profile: People seem to find this robot deliquent a bit unbelievable; however, both male and female readers are enamored of Mechazawa for his cerebral and down-to-earth remarks. But whatever way you look at it, Mechazawa is a robot - though he obnoxiously tries to play himself of as a human.

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!
