Demon Slayer’s Tengen Uzui Returns to the Big Screen—With a Message on Movie Manners

In a delightful twist that blends entertainment with etiquette, anime studio Ufotable has animated a brand-new Demon Slayer: Kimetsu no Yaiba short film—this time, not to slay demons, but to slay bad behavior in movie theaters. Featuring the flamboyant Sound Hashira Tengen Uzui and his three kunoichi wives, this short video is a charming reminder to audiences about proper cinema conduct.

A Surprise Before the Show

From June 20 to July 17, select Toho Cinemas across Japan will screen this exclusive etiquette video ahead of the highly anticipated Infinity Castle movie trilogy. The short is a pre-screening treat for fans, offering a rare chance to see beloved characters in a lighthearted, non-canon setting.

The video is part of a broader promotional campaign leading up to the July 18 release of Demon Slayer: Infinity Castle, the first installment in the trilogy that will adapt the climactic arc of Koyoharu Gotouge‘s manga.

What’s in the Video?

While the full video is only available in theaters, teasers reveal that Tengen Uzui—true to his flashy persona—takes center stage in reminding viewers to:

• Silence their phones
• Avoid talking during the film
• Refrain from recording or taking photos
• Respect fellow moviegoers

His wives—Makio, Suma, and Hinatsuru—join in with their own comedic flair, making the etiquette lesson both entertaining and memorable.

Why This Matters

In an era where cinema etiquette is often overlooked, especially during blockbuster releases, this initiative is a clever way to engage fans while reinforcing respectful behavior. By using familiar characters in a fun, animated format, Ufotable ensures the message resonates without feeling preachy.

It’s also a nod to how anime culture can influence real-world behavior. Fans are more likely to listen when their favorite characters are the ones doing the talking—or in this case, the reminding.

The Bigger Picture: Infinity Castle Hype

The timing of this video couldn’t be better. With anticipation building for the Infinity Castle trilogy, this short serves as both a promotional teaser and a fan-service gem. Directed by Haruo Sotozaki, with character designs by Akira Matsushima and music by Yuki Kajiura and Go Shiina, the trilogy promises to be a cinematic spectacle.

Crunchyroll and Sony Pictures have secured global distribution rights (excluding Japan and select Asian territories), meaning international fans can expect a release soon after the Japanese premiere.

Tengen Uzui’s Return: A Fan Favorite Moment

Tengen Uzui, who played a major role in the Entertainment District Arc, has remained a fan favorite thanks to his charisma, strength, and unique dynamic with his three wives. His return—even in a short, comedic format—has sparked excitement across social media.

This isn’t just a PSA; it’s a celebration of the character and a clever way to keep fans engaged between major story arcs.

Limited-Time Magic

The exclusivity of the video adds to its appeal. Only those attending screenings at participating theaters during the specified window will get to experience it. This scarcity has already led to a surge in ticket sales, with fans eager to catch every bit of new content from the Demon Slayer universe.

Anime Meets Social Responsibility

This initiative also highlights a growing trend in Japanese media: using popular franchises to promote social messages. From disaster preparedness campaigns to public health awareness, anime characters are increasingly being used to influence behavior in positive ways.

By tapping into the emotional connection fans have with characters like Tengen Uzui, studios like Ufotable can deliver important messages that stick.

Final Thoughts

The new Demon Slayer etiquette video is more than just a cute pre-show clip—it’s a brilliant fusion of fandom and responsibility. It shows how anime can be both entertaining and educational, all while building hype for one of the most anticipated anime films of the year.

So if you’re lucky enough to be in Japan this summer, don’t just go for the movie—go for the manners. And remember, when Tengen Uzui tells you to silence your phone, you do it with flair.
