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?
You always play favorites with Hajime! 
You biased old lady! Old lady!
!أنت تفضّلين هاجيمي دائمًا
!أنت متحيّزة أيّتها الجدّة! الجدّة
¡¿Por qué siempre favorece
a Hajime?! ¡No sea injusta, señora!
¡¿Por qué siempre favoreces
a Hajime?! ¡No seas injusta, señora!
Allez, la vieille ! T’abuses !
Y en a que pour Hajime, la vieille !
Fai sempre favoritismi
nei confronti di Hajime! Non vale!
Você sempre puxa para o lado
do Hajime! Isso não é justo!
Ты всегда потакаешь Хадзимэ!
Вредная тётка! Тётка!
