Choi Jihoon es asignado a la Escuela Secundaria Daehun, la peor escuela secundaria en Corea. Se compromete a ser el "Jjang (Top gangster)" aquí, pero la realidad es bastante dura.
On the first day of school, Sin-woo hears about the dangerous student council who even the teachers avoid. When he saves a kid from being cheated by them, he becomes known as 'one punch man.' After being expelled from defending a friend from the student council's torment, he is invited to join them, which confuses him.
