The movie exists entirely to let you say goodbye properly, to spend time with the kids from Class 3-E you barely got to know, watch them remember Koro Sensei, feel what they felt. It's not about plot momentum. It's about the weight of a teacher who changed everything, told through the people he changed most. If you finished the anime and thought "I'm not ready to leave yet," this is the film that lets you stay.

As graduation approaches, the students of Class 3-E look back on the year they spent with Koro Sensei and on the lessons he will leave them with. Released to mark the tenth anniversary of the Assassination Classroom TV anime, the film brings to the screen episodes that the original series left out. Expect a blend of action, comedy, science fiction and the supernatural as the class reflects on their time together.
