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 taught me how wonderful it is to 
experience the prime of our lives,
لقد علّمتني كم من الرّائع 
،أن نعيش أفضل أيّام حياتنا
Ihre Lehre, wie
wunderbar die Jugend ist,
Tú me enseñaste lo maravillosa
que es la juventud,
Tú me enseñaste lo maravillosa
que es la juventud,
Vous m’avez montré à quel point
l’adolescence est formidable.
Mi hai fatto scoprire
gli splendidi anni della gioventù
Você me ensinou sobre os
belos anos da nossa juventude,
Ты научил меня,
как прекрасна пора юности,
