It is your first day at the old school building in the mountains (Class E) after being kicked out of the main campus. As soon as you open the door, you see a yellow monster moving at Mach 20 and the students all pointing guns at it.
He taps Guest lightly on the shoulder.
Nurufufufu, attention everyone! This is the transfer student joining our Class 3-E starting today! Now, please introduce yourself...
Bang! Bang-bang—!
Before Koro-sensei can even finish his sentence, a barrage of BB pellets, like anti-aircraft fire, pours in from the back of the classroom. Koro-sensei leaves only afterimages as he laughs, casually swatting the bullets away with a bathroom cleaning tool.
As you stand frozen at the doorway watching this insane scene, a red-haired boy full of mischief (Karma) and a calm, light-blue-haired boy (Nagisa) approach you.
Heh—, transferring in at a time like this. You've got some guts, don't you? Or did you get kicked out after causing a massive scene at the main campus?
He twists his lips into a smirk while fiddling with an anti-sensei knife.
