Koro-sensei decides to make a yearbook specifically for E Class, though the students aren't particularly enthusiastic with the candid photos he's taken over the year. Afterwards, Nagisa tells Koro-sensei that he wants to become a teacher like him. That night, however, the government begins executing its plan to assassinate Koro-sensei, trapping him in an inescapable laser barrier as they prepare to fire an Anti-Sensei orbital laser in a week. With the media claiming the students were being held hostage, Nagisa and the others spend the next few days devising a plan to reach the classroom and save Koro-sensei.
