Ayanokouji Kiyotaka has just enrolled at Tokyo Koudo Ikusei Senior High School, where it's said that 100% of students go on to college or find employment. But he ends up in Class 1-D, which is full of all the school's problem children.

One month later, Ayanokouji, Horikita, and the students of Class D learn the truth of the system in place within their school...
