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?
Hey. If you're gonna stay at this 
school, prepare yourself, Katou!
Oye, si vas a permanecer en 
la escuela prepárate, Kato.
Ei. Se quiser continuar aqui, 
é melhor se preparar, Katou!
