Classroom of the Dead Assassins (What I Thought It Was Series)

"What's going on, I died didn't I?" I opened my eyes to see... A giant yellow octopus!?!? This had better be good.

OK, so I saw the ending to Assassination Classroom before I watched the anime or read the manga. I didn't understand what was happening and assumed it was something... more crazy than it actually was. This is what I thought it was.

That's why I used an Assassination Classroom image for the cover. I don't own the image.
