Demon Slayer: Kimetsu no Yaiba is once again in the spotlight, but this time for a delicate reason. As reported on the series' official X profile (formerly Twitter), a video illegally recorded during special screenings in Japan has leaked online, containing previously unreleased scenes from the highly anticipated Infinity Castle arc.

Illegal recording and severe consequences

According to the statement, the video in question was captured during the revival screening of Demon Slayer: Mugen Train , which is currently showing in Japanese theaters. At the end of the screening, the theater screens an exclusive trailer for the new arc, but unfortunately, someone secretly records it and posts it on social media.

According to Japan's Unauthorized Filming Prevention Act, this type of action constitutes a crime. Furthermore, posting such content on platforms like X, YouTube, TikTok, or Facebook constitutes copyright infringement. Therefore, the courts can punish those responsible with up to 10 years in prison, a fine of up to 10 million yen—or both.

Demon Slayer: Infinite Castle premieres in theaters

While the leak sparked controversy, the hype continues. After all, the official trailer for the Infinity Castle will be shown in North American theaters starting May 14th. In Japan, the film's premiere is scheduled for July 18th. Crunchyroll, in partnership with Sony Pictures, will release the film globally on August 14th, 2025.

Currently, all seasons of the series are available on Crunchyroll. The series is set in the Taisho period and follows the journey of Tanjiro, a young man who decides to become a demon hunter to save his sister Nezuko—transformed into an oni—and avenge his family.
