The official X (formerly Twitter) account for the anime Demon Slayer: Kimetsu no Yaiba issued a public warning on May 11 following reports that exclusive footage from the upcoming Mugen Castle Arc movie had been illicitly recorded and shared online.

The trailer in question plays at the end of the revival screening of Demon Slayer: Mugen Train, which has been showing in theaters since May 9. This new trailer features never-before-seen footage, making it a major highlight for fans. However, the official X account confirmed that recordings of this theater-only preview have surfaced online without authorization.

“We have confirmed that the exclusive trailer for the Mugen Castle Arc, which plays at the end of the currently screening Demon Slayer: Mugen Train Revival, has been illegally recorded and uploaded online,” the statement read.

The post emphasized that filming inside movie theaters constitutes a criminal offense under Japan’s Act on Prevention of Unauthorized Recording of Films (commonly referred to as the Anti-Camcording Law). Furthermore, uploading such footage to platforms like X, YouTube, TikTok, or Facebook is a violation of copyright law.

“Illegal recording in theaters is a criminal act. Uploading such recordings to social media platforms constitutes copyright infringement. Violations of the Anti-Camcording Law and Copyright Law may be subject to up to 10 years of imprisonment, a fine of up to 10 million yen, or both,” the official account warned.

The Mugen Train Revival is a special five-week theatrical run, while the highly anticipated Mugen Castle Arc will debut its first chapter in theaters on July 18.

Story Summary of Demon Slayer: Infinity Castle Arc

Tanjiro Kamado, who joined the Demon Slayer Corps in hopes of saving his demon-turned sister Nezuko, fought alongside close allies Zenitsu Agatsuma and Inosuke Hashibira, growing stronger through numerous battles. He also shared fierce encounters with elite swordsmen known as the Hashira: Flame Hashira Kyojuro Rengoku in the Mugen Train, Sound Hashira Tengen Uzui in the Entertainment District, and Mist Hashira Muichiro Tokito and Love Hashira Mitsuri Kanroji in the Swordsmith Village.

As the Corps prepares for the final battle against demons, the Hashira and their comrades undergo intensive joint training. But their efforts are abruptly disrupted when Muzan Kibutsuji, the originator of all demons, appears at the Demon Slayer Corps' headquarters. In a sudden twist, Tanjiro and the Hashira are pulled into a mysterious dimension—Infinity Castle, the stronghold of the demons.

Thus begins the final confrontation between the Demon Slayer Corps and the demons.
