For fans of Assassination Classroom, the journey of Class 3-E and their eccentric yellow teacher Koro-sensei seemed to have ended years ago. Yet, in 2025, the franchise is making an exciting return with a brand-new anime movie that adapts stories from the manga that were never animated before. This news has electrified the fandom worldwide, proving that Assassination Classroom still holds a special place in the hearts of anime fans.
A Quick Look Back at Assassination Classroom
Assassination Classroom (Ansatsu Kyoushitsu), created by Yūsei Matsui, first ran as a manga in Weekly Shōnen Jump from 2012 to 2016. The story follows the eccentric alien-like teacher Koro-sensei, who claims he will destroy Earth within a year unless his students can assassinate him first. While the premise is bizarre, the series balances dark comedy, action, and heartfelt lessons about growth, friendship, and perseverance.
The manga received a two-season anime adaptation by Lerche (2015–2016), covering most of the story and concluding with the unforgettable finale. However, not every chapter and side story made it to the screen. That’s what makes the new movie announcement so exciting—it promises to revisit unadapted material while giving fans more time with beloved characters.
The Big News: A New Assassination Classroom Movie
In early September 2025, the official Assassination Classroom team announced a new anime movie project. The film will cover unadapted manga stories that were skipped in the original TV run. This means fans can finally see some of the lighthearted and character-driven chapters brought to life on screen for the very first time.
The movie also arrives as part of the celebration of Assassination Classroom’s enduring legacy, reminding audiences of why the series remains so impactful even years after its conclusion.

Here’s the official teaser trailer for the upcoming movie:
Which Stories Will Be Adapted?
While the production team has not revealed the full list of chapters, reports suggest that the movie will focus on unadapted side stories and bonus chapters from the manga. These often highlighted Class 3-E’s daily life, comedic antics, and deeper bonds between students.
Fans speculate that some of the most requested unadapted stories may include:
- Extra training sessions with Koro-sensei’s unusual methods.
- More focus on lesser-seen students in Class 3-E.
- Slice-of-life moments that blend humor with emotional growth.
If true, this will allow audiences to relive the Assassination Classroom world with a fresh perspective, without retreading the already-adapted ending.
Staff and Production Details
- Studio: Lerche, the same studio behind the original anime, is returning to handle the movie.
- Director: Seiji Kishi (who directed the TV anime) is reportedly back to oversee the film.
- Voice Cast: Jun Fukuyama will reprise his role as Koro-sensei, while the students of Class 3-E will also have their original cast return.
This consistency ensures that the film retains the same spirit and tone as the anime fans already love.
Release Date and Distribution
The movie is currently set to premiere in 2025 in Japan, with an international release expected shortly afterward. Streaming platforms like Crunchyroll or Netflix are strong contenders to host the movie globally, though official details have not been confirmed.
Given the series’ massive popularity, fans can expect a relatively quick worldwide release once it debuts in Japanese theaters.
Why Fans Are Excited
There are several reasons why the announcement of this movie has generated so much hype:
- Unadapted Content Finally Animated: Longtime manga readers have always wanted to see these chapters animated, and now it’s happening.
- Nostalgia Factor: Assassination Classroom left a lasting impact, and revisiting the world after so many years feels special.
- Original Staff Returning: Having Lerche and Seiji Kishi back reassures fans that the movie will maintain the quality and tone of the original anime.
- A Fresh Experience: Since the main story was already concluded, the film provides a lighter, more fun experience without altering the ending.
Will There Be More After This Movie?
While nothing has been officially confirmed, some fans are hopeful that this project could open the door to even more Assassination Classroom spin-offs, OVAs, or side-story adaptations. With the success of other Shōnen Jump revival projects, it wouldn’t be surprising if this movie leads to further content down the line.
Final Thoughts
The announcement of a new Assassination Classroom movie is a reminder of just how beloved the series remains. By adapting previously skipped manga stories, the film offers both old fans and new viewers a chance to return to Class 3-E and spend more time with Koro-sensei and his students.
For longtime followers, this is both a nostalgic trip and a rewarding chance to experience the world in a new way. For newcomers, it’s an opportunity to explore more of the humor, heart, and creativity that made Assassination Classroom one of the most unique anime series of its generation.
One thing is certain: even years later, Koro-sensei continues to teach us lessons—this time, through brand-new stories finally getting the spotlight they deserve.
