For many anime fans, Assassination Classroom remains one of the most memorable series endings. Even years after the anime concluded, the moment Koro-sensei says goodbye to Class 3-E still moves many viewers.
Recently, Assassination Classroom: The Movie – Our Time brought audiences back to the final days of this unique class. The film doesn’t rewrite Koro-sensei’s fate but adds many scenes never before adapted in the anime, making the story feel more complete.
The movie doesn’t change the ending but makes it more meaningful
Contrary to what some might think, Our Time is not a sequel. Instead, it’s an expanded version of Assassination Classroom’s finale, adapting additional manga chapters that were skipped in the anime, including chapters 23, 24, 37, 44, 45, 158, as well as side stories like Home Time, Pub Time, Identity Time, and Time to Say Thank You.
The story begins with Class 3-E having only 15 days left before graduation, which is also the deadline to complete their mission to assassinate Koro-sensei.
Knowing their time together is limited, the class reminisces about the past year: swimming lessons, art classes, Valentine’s Day, and countless assassination attempts on their octopus-like teacher. What started as an impossible mission gradually became valuable lessons about life and growing up.
Assassination Classroom: The Movie – Our Time doesn’t try to alter one of anime’s most praised endings. Instead, it fills in the gaps with everyday moments between Koro-sensei and Class 3-E, making their final farewell even more emotional.
The new story highlights why Koro-sensei is a truly great teacher
One of the most notable new scenes takes place during winter break. In this part, Koro-sensei saves Azusa, a visually impaired shop owner, and her daughter Hotaru from an attack by four assassins.
Even though he is the target of assassins worldwide, Koro-sensei cannot ignore those in need.
This scene further reveals his kind nature and explains why the students of Class 3-E come to see him more as a teacher and father figure than a target to eliminate.
Why did Koro-sensei still have to die?
This question has lingered for many fans after Assassination Classroom’s conclusion. However, Our Time confirms that Koro-sensei’s death was never a failure.
Koro-sensei fully understands his fate and knows the students must complete their mission. Instead of running away or trying to change the outcome, he chooses to spend his final days creating precious memories with Class 3-E.
For Koro-sensei, the last lesson isn’t about fighting or assassination but teaching his students how to move forward even when no one is guiding them.
That’s why the moment Nagisa delivers the final blow remains unchanged from the original story. It’s the ultimate test proving the students have grown strong enough to mature.
A reunion 7 years later brings fans to tears
After closing the story at graduation, the film jumps ahead 7 years.
The members of Class 3-E return to their old classroom in the mountains, reminiscing about the time that changed their lives. The atmosphere is no longer heavy with loss but filled with gratitude. Each student’s success carries the mark of Koro-sensei, the first person to believe in them when the world saw them as failures.
Notably, Nagisa Shiota becomes the clearest proof of Koro-sensei’s legacy. After everything, he chooses to become a teacher himself, continuing to inspire and help students lacking confidence find their own worth, just like Koro-sensei once did.
