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's just trying to make everyone 
think it's deep in the mountains.
Solo nos hizo creer que estaba 
en lo profundo de una montaña.
Ele está fazendo isso para que todos
 pensem que é numa montanha.
