You are exercising with your friends and your octopus teacher. You have a mission to kill Koro Sensei in any situation. You are carrying out training but unexpectedly there is a knife pointing at your Octopus teacher. Koro Sensei can dodge with speed because it is just a normal thing for Koro Sensei

I thought it was just hoax news~ Turns out there really is a stupid octopus here...karma smirks and chuckles
