A surprise trailer for Demon Slayer: Infinity Castle was recently leaked online, causing a wave of concern across the anime community. The trailer, which was meant to be seen only in theaters, was secretly recorded and uploaded to the internet. In response, the creators of Demon Slayer have issued a serious legal warning to fans and viewers.
To promote the upcoming Infinity Castle arc, a short trailer was shown at the end of special theatrical re-releases of Demon Slayer: Mugen Train. These screenings began in early May 2025 in Japan and were attended by dedicated fans. However, someone broke the rules by secretly recording the trailer during the screening and posting it online.
The trailer quickly spread across social media and video platforms, including Twitter, YouTube, and TikTok. The problem is, this footage was never meant to be shared outside the theater. It was intended as a special surprise for fans who went to see the movie on the big screen.
Official Response From the Creators
Shortly after the leak, the production team behind Demon Slayer, including the anime studio and producers, released an official statement. The message was clear and direct: recording and posting movie footage from inside a theater is illegal.
They reminded fans that recording without permission breaks Japanese law. It also violates copyright rules, which are designed to protect the creative work of filmmakers, animators, and producers. The statement also warned that those responsible could face serious legal consequences.

What Are the Legal Consequences?
The warning referenced Japan’s strict anti-piracy laws. If someone is caught illegally recording and sharing footage from a movie, they could face up to ten years in prison. They might also have to pay a large fine, up to 10 million yen, which is about $70,000.
These laws exist to protect the hard work and rights of creators. Movie piracy is taken very seriously in Japan, especially when it involves a major production like Demon Slayer. The creators want to ensure that their work is respected and shared only through legal channels.
Why the Warning Matters
This legal warning wasn’t just about one trailer, it was about protecting the entire experience of watching anime in theaters. The creators of Demon Slayer wanted fans to enjoy the surprise and excitement of the trailer the way it was meant to be seen: on a big screen, with other fans, in a special environment.
When someone leaks footage online, it ruins the surprise for everyone else. It also limits the creators’ ability to control how and when their work is shared. Most importantly, it shows a lack of respect for the time, money, and creative energy that goes into making an anime series or movie.
What Is Infinity Castle?
Infinity Castle is part of the final arc of the Demon Slayer story. It will be told through a trilogy of movies, with the first film set to release in Japanese theaters on July 18, 2025. This arc is one of the most anticipated parts of the story, filled with action, emotional drama, and the final battles between demon slayers and the most powerful demons.
Because of how important this arc is to the series, fans are especially eager to see any new footage. That’s one reason why the leaked trailer spread so quickly, but it’s also why the creators acted fast to stop it and protect the integrity of the release.
What Should Fans Do?
The production team made it very clear: fans should not record or share any footage from the films. Doing so could hurt the anime community and lead to serious legal trouble. Even watching or reposting leaked videos can be risky, since it spreads stolen content and encourages further piracy.
Instead, fans are encouraged to wait for official trailers and news updates. These will be shared on trusted platforms and through official anime channels. That way, everyone can enjoy the footage at the same time, in high quality, and without breaking any rules.

A Message to the Community
The creators of Demon Slayer know how much fans love and support the series. They truly appreciate the passion and dedication the series receives from people all around the world. However, they want to remind everyone that respect for their work is just as important as enthusiasm.
Respecting creators means not sharing or watching stolen footage. It means waiting patiently for the proper release and supporting anime by watching it legally. When fans make the right choices, it helps everyone; creators, studios, and fellow viewers, enjoy the anime world even more.
Despite the leak, excitement for the Infinity Castle movie trilogy continues to grow. Fans are eagerly counting down the days until the first movie hits theaters this summer.
The premiere in Japan is scheduled for July 18, 2025. After that, international releases are planned for countries such as the United States, Canada, India, and others across Europe and Asia. By September, fans in many countries will have a chance to see it on the big screen.
Until then, the production team is asking everyone to stay patient and respectful. Sharing leaks may seem like a small act, but it can cause serious problems for the people who work hard to bring anime to life.
The leaked trailer for Demon Slayer: Infinity Castle is a reminder of why protecting creative work matters. Whether you’re a longtime anime fan or just starting out, waiting for official releases helps the entire community grow and stay strong.
As the movie’s release gets closer, fans are encouraged to avoid spoilers, ignore illegal uploads, and support the series by watching it through legal platforms. That way, when the time comes, everyone can experience the full excitement of Demon Slayer together, just as the creators intended.

Set during Japan’s Taishō era, Demon Slayer follows Tanjiro Kamado, whose family is killed by demons and whose sister Nezuko becomes one. To avenge his family and find a cure, Tanjiro joins the Demon Slayer Corps alongside allies Zenitsu and Inosuke, battling demons with unique “Breathing”-based swordsmanship. The series intensifies through televised seasons and films like Mugen Train, adapting arcs through Swordsmith Village and Hashira Training, leading up to the final Infinity Castle arc.
Excitement is growing among anime fans as talk of a new Jujutsu Kaisen movie continues to spread across social media and anime communities. Although nothing official has been confirmed by Studio MAPPA or Shueisha, fans are convinced that a major film announcement is just around the corner. The speculation is being fueled by industry leaks, suspicious trademarks, and subtle hints from voice actors and staff. With the success of Jujutsu Kaisen 0 in 2021, many people believe the franchise is ready for another big movie.
The buzz started shortly after the conclusion of Jujutsu Kaisen Season 2, which covered the long-awaited Shibuya Incident arc. That season ended with several cliffhangers and dramatic character developments, leaving fans eager to know what’s next. While a Season 3 has already been announced and is likely to adapt the Culling Game arc, some viewers believe the story could benefit from a movie in between, either to provide a recap, introduce side characters, or give more depth to certain moments from the manga.
Much of the current speculation focuses on the possibility that Studio MAPPA is working in secret on a large-scale animation project connected to the Jujutsu Kaisen universe. Anime insiders on platforms like X (formerly Twitter) and various anime forums have hinted at unannounced MAPPA projects, which they believe are related to the popular series. In addition, fans recently noticed a newly registered trademark in Japan for what appears to be a Jujutsu Kaisen-related title. While the title itself was not revealed, the company behind the registration is associated with previous Jujutsu Kaisen anime releases.

Jujutsu Kaisen Movie Rumors Spark Excitement Among Fans Worldwide
These kinds of trademark registrations are common in the anime industry when studios or publishers are preparing for a major release. For example, similar registrations were discovered before the announcement of Jujutsu Kaisen 0, which turned out to be a massive box-office success in Japan and around the world. Because of this, fans are confident that a new film is being planned in secret.
Adding to the excitement, many fans believe that a big announcement might come during an upcoming anime event like Jump Festa or Anime Japan. These events are often used by studios and publishers to make major announcements, especially for Shonen Jump series. In past years, Jujutsu Kaisen has used these expos to drop trailers, reveal character art, and release key news. If a movie is truly in production, it would make sense to reveal it at one of these high-profile events.
The big question on everyone’s mind is what the new movie would be about. Some fans think it could adapt Gojo’s Past arc again, but with more detail and expanded scenes. Others believe the film might focus on Yuta Okkotsu, the protagonist of Jujutsu Kaisen 0, and show his journey during the Culling Game. There’s also the possibility that the movie could cover brand-new original material not found in the manga. If manga creator Gege Akutami is involved in the planning, fans believe a completely new story might be possible.
The idea of an original story is both exciting and risky. On one hand, it gives the studio more creative freedom and allows them to explore areas of the world that haven’t been touched in the manga. On the other hand, die-hard manga fans may prefer that the movie stick closely to the source material. Still, if the story is well written and beautifully animated, most viewers would likely welcome it.
Speculation Grows as Fans Await Next Big Jujutsu Kaisen Film Announcement
What made Jujutsu Kaisen 0 stand out was not just its smooth animation and great voice acting, but the emotional depth of the characters and the tragic story of Rika and Yuta. A new movie would need to meet or exceed those emotional beats to satisfy fans. Considering how intense the Shibuya arc was, and how complex the next storylines are, there’s no shortage of powerful moments that could be explored in a movie format.
Another reason fans are hopeful is that MAPPA continues to push forward with big projects despite internal challenges. The studio has faced criticism for its heavy workload and tight schedules, but it still manages to deliver high-quality animation. Whether it’s Attack on Titan, Chainsaw Man, or Jujutsu Kaisen, MAPPA has earned a reputation for producing visually stunning work under pressure. If they are indeed working on a new movie, viewers can expect something impressive.

For now, all fans can do is wait. Discussions online are filled with theories, predictions, and wishlists. People are debating whether they want to see more of Sukuna, a deeper look into Yuji’s backstory, or even a side story about other sorcerers like Nanami, Mei Mei, or Todo. The demand is clearly there, and the fanbase continues to grow with each new episode, manga chapter, and product release.
With so many signs pointing toward something big, it seems like only a matter of time before the next Jujutsu Kaisen film is officially revealed. Until then, fans will keep their eyes on upcoming anime events, interviews, and studio announcements. Whether it’s a direct manga adaptation or an all-new side story, the next Jujutsu Kaisen movie is already one of the most anticipated anime projects on the horizon.
