That's... not at ALL what Assassination Classroom is about. Like, not even CLOSE. There are no zombies ANYWHERE in AC.

Alien destroys the moon, announces that he'll destroy Earth in a year if he isn't killed, then becomes a teacher at a middle school to teach kids while also training them in assassination so that they can kill him. Where exactly did you get "porn movie but with sex replaced with zombies" from that? Or is there a joke I'm missing?
