Placement Test Time!

It's been 2 years since E class killed Koro~Sensei and now the placement test is upon you! The results have put you back into the dumps except one more worse the F class. You lost contact with all of E class and run into Nagisa and the rest of E class in F class! All but one Cocky,Egotistical Cherry Top. Karma. We're is he? No one knows! At least not now
