Seitarou Tanabata is all fired up for his first teaching job at a high school
But Nanba Building 13 High School l is filled with delinquents.
The students are troublemakers and even the teachers are odd.
Seitarou is already bullied by 4 students in the 3rd year, class 13 on his first day.
Then, the number 1 troublemaker, Hajime Sugoroku, returns after serving his suspencion.
Can Seitarou ever become the teacher he always wanted to be?
We actually have to pay attention in class.
