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?
Can I be honest? I just joined the Student 
Council because I wanted this armband.
Escucha, la verdad es que ingresé al 
consejo porque quería este brazalete.
Posso ser sincero? Só entrei no
 Conselho Estudantil por esta faixa.
