Ladies and Gentlemen, meet Yagami-san, the only one section chief you would never want to work with, unless you like the kind of stupid guy who got in the workplace by a gigantic cosmic error in the arrangement of the stars on the recruitment day.

In a school where after school activities are mandatory among all students, Hajime and her friend Sayo come across a new club that they have never seen before. The club is called "The Cultural Activity Preservation Club." The two enter the room to find all kinds of analog jobs and activities, such as handcrafting mats and toothpicks. This is a unique cultural manga mixed with comedy so as not to bore you, this is Double J!

Welcome to Cromartie High—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!
