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?
He may not have hit a teacher, 
but he kidnapped one!
no lo golpeó, pero lo secuestró.
Ele não bateu em um professor,
 mas sequestrou!
