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?
They're just taking out their 
pent-up energy on each other!
!إنّهما ينفّسان عن طاقتيهما المكبوتة على بعضيهما
Sie lassen nur ihre überschüssige
Energie aneinander aus!
¡Solo descargan sus energías
el uno contra el otro!
¡Solo descargan sus energías
el uno contra el otro!
Ils se rentrent dedans
juste pour extérioriser !
Riversano solo la propria energia 
l'uno sull'altro!
Estão apenas trocando a energia
reprimida um contra o outro!
Они просто вымещают друг
на друге скопившуюся энергию!
