In a dazzling prelude to the highly anticipated Demon Slayer: Kimetsu no Yaiba Infinity Castle trilogy, Japan’s TOHO Cinemas is set to screen a vibrant, ufotable-crafted theater etiquette video featuring the flamboyant Sound Hashira, Tengen Uzui, and his three wives—Makaio, Suma, and Hinatsume. This exclusive short, running from June 20 to July 17, 2025, will play before every film at TOHO Cinemas, offering audiences a stylish reminder of movie theater manners while building excitement for the first Infinity Castle movie, slated for release on July 18, 2025.
The "etiquette" short, produced by Ufotable, the acclaimed studio behind Demon Slayer: Kimetsu no Yaiba, showcases Tengen Uzui’s larger-than-life personality as he and his wives guide viewers through proper cinema conduct. Known for his extravagant demeanor and unyielding charisma, Tengen takes center stage, delivering lessons with his signature flair. Makaio, Suma, and Hinatsume complement his performance, their dynamic interplay bringing humor and charm to the mundane task of reminding audiences to silence phones, avoid talking, and refrain from disruptive behavior.
A sneak peek of the short reveals ufotable’s signature visual brilliance—vibrant colors, fluid animation, and meticulous attention to detail. The clip captures Tengen’s booming voice and the wives’ playful banter, transforming a standard public service announcement into a mini-spectacle that feels like an extension of the Demon Slayer universe. This marks another creative collaboration between ufotable and TOHO Cinemas, reinforcing the studio’s knack for blending storytelling with promotional ingenuity.
The etiquette short serves as a strategic appetizer for the Demon Slayer: Kimetsu no Yaiba Infinity Castle trilogy, which adapts the climactic final arc of Koyoharu Gotouge’s manga. The first film, set to premiere in Japan on July 18, 2025, will dive into the intense battles within the Infinity Castle, where Tanjiro Kamado and the Demon Slayer Corps face off against Muzan Kibutsuji’s Upper Rank demons. A new trailer for the film is scheduled to drop on June 28, 2025, further stoking anticipation for what promises to be a visually stunning and emotionally charged cinematic experience.
By featuring Tengen Uzui and his wives in the etiquette short, ufotable taps into the popularity of these fan-favorite characters, who played pivotal roles in the Entertainment District Arc. Their inclusion not only ensures an engaging viewing experience but also underscores the thematic continuity of Demon Slayer—a story of camaraderie, resilience, and spectacle. The short’s limited run at TOHO Cinemas adds an element of exclusivity, encouraging fans to visit theaters early to catch this unique piece of Demon Slayer content.
