When a bullying teacher from Katou Kiri's past comes to Kaimei Academy, he harasses the Sket-dan. But will the bully's actions push Student Council member/trained ninja Katou over the edge?
It was a shitty, rotten, worthless school.
Fue una asquerosa y repugnante escuela.
Era uma escola podre e 
sem nenhum mérito.
