The first sneak peeks of the 2021 Demon Slayer Mugen Train film in theaters worldwide. Some viewers chose to illegally record and distribute these leaks, and Demon Slayer's team is taking action by issuing a serious warning to anyone planning to engage in similar behavior.
With the new movie coming out this July 2025 in Japan, Demon Slayer's team wants to ensure that no one spreads any parts of the film illegally, and they will fight back against those who do. Anyone who posts Demon Slayer leaks will be subject to legal action, hefty fines, and even jail time.

It's True, Demon Slayer's Best Movie Is Returning to Theaters In a Way Nobody Has Seen Before
Demon Slayer: Mugen Train is easily the biggest anime movie of the decade, and fans can relive it in theaters in a brand-new way starting next month.
Distributing stolen content like this falls under the Film Piracy Prevention Act and the Copyright Act, the X post explains, meaning that those responsible could be hit with either "imprisonment of up to 10 years or a fine of up to a million yen, or both." This stern message will likely prevent future spoilers from emerging online, since this is quite a consequential punishment. The Infinity Castle trilogy, which will mark Demon Slayer's finale and draw the anime to a close, is set to be one of the biggest and most anticipated events in anime history.

Rather than simply continuing to make new anime seasons until the manga's conclusion, Demon Slayer's team elected to think larger, likely inspired by the success of the franchise's past films like Mugen Train, and create a three-part movie event to be shown in theaters worldwide that will conclude the series. Since these films are likely to be Demon Slayer's most successful projects and will show off some of the most emotional and jaw-dropping moments in the manga, Demon Slayer's team does not want any spoilers to take away from the long-awaited time when the Infinity Castle finale finally hits screens.

Believe It or Not, One of Anime's Top Piracy Platforms Now Brings In More Visitors Than Disney+
The rise of illegal pirated content is a major problem that is getting out of control, and one popular anime piracy website proves it.
Anime piracy has been a sizable problem in the industry for quite a while, and its negative effects are only growing as technology gets more advanced. Countless websites exist that are solely dedicated to distributing pirated anime illegally, and even though studios, companies, and anti-piracy organizations are cracking down on the problem with increased vigor, the issue is still out of control. Few companies have released a warning as grave as the one for Demon Slayer though, so the threat of legal action may just be enough to keep the pirates at bay this time.
