by A brand-new movie etiquette lesson video created in collaboration with TOHO Cinemas and the upcoming film Demon Slayer: Kimetsu no Yaiba Mugen Castle Arc Chapter 1: Akaza Returns has been released in full on Aniplex’s official YouTube channel.
The special video features fan-favorite character Tengen Uzui alongside his three wives—Makio, Suma, and Hinatsuru—in an original short animation produced by ufotable, the studio behind the anime adaptation of Demon Slayer.
This newly animated etiquette guide blends humor, character charm, and cinema manners—delighting fans while promoting proper theater behavior.
What Is the Movie Etiquette Video About?
The collaboration was created to coincide with screenings of Mugen Castle Arc Chapter 1: Akaza Returns, which premiered on July 18, 2025.
In the video:
- Tengen Uzui dramatically explains cinema rules in his signature flashy style
- Makio, Suma, and Hinatsuru assist in demonstrating proper theater manners
- Viewers are reminded not to use smartphones during screenings
- Talking loudly and disturbing other moviegoers is discouraged
- Proper etiquette such as remaining seated during the film is emphasized
Rather than a standard instructional announcement, the segment is fully animated in ufotable’s polished style, making it feel like a bonus mini-episode rather than a commercial.
For beginners, movie etiquette videos are short animations shown before films in Japanese theaters to remind audiences of viewing rules. This collaboration elevates that concept with original animation and beloved characters.
Why Tengen Uzui?
Tengen Uzui, the former Sound Hashira, is known for his flamboyant personality and larger-than-life presence. His theatrical nature makes him a perfect fit for delivering bold and energetic etiquette reminders.
His wives—Makio, Suma, and Hinatsuru—add comedic timing and personality to the lesson, turning what could have been a routine PSA into a memorable fan experience.
This approach not only entertains but strengthens fan engagement ahead of the film’s continued theatrical run.
