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?
Why do you keep falling for 
the same trick every morning?
لماذا تسقط ضحيّة لنفس الخدعة كلّ صباح؟
Erklär mir mal, warum du jeden Morgen
auf denselben Trick reinfällst …
¿Cómo es que sigues cayendo
en el mismo truco cada mañana?
¿Cómo es que sigues cayendo
en el mismo truco cada mañana?
D’ailleurs, comment tu fais pour tomber
dans le panneau à chaque fois ?
Come fai a cascare
nello stesso scherzo ogni mattina?
Por que você cai no mesmo
truque toda manhã?
Слушай, как можно попадаться в одну
и ту же ловушку каждое божье утро?
