Cromartie High School

It’s Takashi Kamiyama’s first day at Cromartie High. The problem is that it’s a school for delinquents and Kamiyama doesn’t exactly fit in, Luckily, he has Shinjiro Hayashida to show him around. They go through the school meeting each of its wacky and hilarious students, including the three weirdest. When they come to the weirdest of three weirdest, Mechazawa, they instantly recognize that he’s a robot. But, no one else says anything.

Kamiyama and Hayashida are the only two who seem to realize that Mechazawa is actually a robot. They spy on him to see if anyone else notices that he’s a robot. After two close calls, the boys give up. After school they spot Mechazawa getting beat up by some bullies from a rival school. Kamiyama and Hayashida spy on him some more, but nobody seems to notice, not even when they stab Mechazawa with a knife that simply breaks on his hard body.

Shinjiro Hayashida hears Shinichi Mechazawa humming a song in the bathroom. Later that day, he starts humming the same tune, but can’t remember the name or artist. He asks Kamiyama, but he can’t remember it either. Pretty soon, the whole school is humming the song thinking of what its called. At the end of the day, nobody figured it out. As Kamiyama heads out, he hears Mechazawa humming the song! He asks him about it, but accidentally says that he knows it. Now, he can’t ask the only person who knows the song’s name, or else he’ll look like a “tool”.

Noboru Yamanouchi of Destrade High is not only strong in fights, he is also a great comedy critic! However, he has a rival named Honeyboy, who might turn out to be someone he knows...

Yutaka Takenouchi is the most respected yet feared first year at Cromartie High. He is completely unstoppable in battle, thus no one dares to pick a fight with him or anger him. But he has a weakness - he gets dizzy too easily. What will happen when he takes a trip to Nikkou? And will he be able to save Maeda after spending some much time in a taxi?!

Takeshi Hokuto is the son of the chairman of Cromartie High. He doesn’t want to go to a school with delinquents, but assures himself that his father can expel anyone he doesn’t like. But, is that enough? And when Hayashida tells him that their school is municipal, can Hokuto cover up his mistake of attending the wrong school?!
