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?
After he gets down on his hands and knees 
and licks my shoes, he's expelled, dumbass!
¡Te arrodillarás, me lamerás los zapatos 
y luego quedarás fuera de la escuela, idiota!
Ele será expulso...
