DEMON SLAYER: KIMETSU NO YAIBA - THE MOVIE: INFINITY CASTLE ARC Trailer Leaks Online

The anime world is buzzing with excitement as the first teaser trailer for Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle Arc Chapter One has leaked online. This trailer, which debuted alongside the theatrical re-release of Mugen Train in Japan earlier this week, has sent fans into a frenzy, offering a glimpse into the highly anticipated final arc of the beloved series.

The leak, reported by AnimeMojo on May 10, 2025, surfaced just days after Crunchyroll and Sony Pictures Entertainment confirmed that a 60-second preview would be shown exclusively during the Mugen Train theatrical screenings in the U.S., starting May 14, 2025. While the official trailer was meant to be an exclusive theater experience, its online appearance has given fans worldwide an early look at what’s to come.

Demon Slayer: Infinity Castle marks the cinematic adaptation of the manga’s final battle, encompassing the Infinity Castle Arc (chapters 137-183) and potentially the Sunrise Countdown Arc (chapters 184-205). Directed by Haruo Sotozaki and produced by Ufotable, the film promises to deliver the intense action, emotional depth, and stunning animation that the series is known for. The story picks up after the Hashira Training Arc, where Tanjiro Kamado and the Hashira are drawn into Muzan Kibutsuji’s labyrinthine stronghold, the Infinity Castle, to face off against the demon king and his Upper Rank demons in a climactic showdown.

The leaked trailer, though brief, reportedly features a haunting monologue from Muzan, paired with striking black-and-white visuals of the ever-shifting Infinity Castle. Fans have noted glimpses of the Hashira charging into battle, setting the stage for what promises to be an epic confrontation. While the trailer lacks extensive footage, its tone and atmosphere have already sparked widespread speculation and excitement across social media platforms.

Originally announced as a trilogy following the Season 4 finale in 2024, recent updates on the official Demon Slayer website have removed the "trilogy" label, leading some to speculate that Ufotable might condense the arc into fewer films or adapt the Sunrise Countdown Arc separately. The first film is confirmed to premiere in Japan on July 18, 2025, with a U.S. release scheduled for September 12, 2025, distributed by Crunchyroll and Sony Pictures Entertainment.

The leak has raised questions about the impact of such early releases on the theatrical experience, especially since the trailer was intended as an exclusive perk for moviegoers attending the Mugen Train re-release. Some fans argue that the leak builds hype, while others feel it diminishes the special allure of seeing it on the big screen first. Regardless, the online buzz demonstrates the enormous global following that Demon Slayer has established since its release.

As the release date approaches, Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle is shaping up to be a monumental event in the anime world, potentially rivaling the record-breaking success of Mugen Train, which grossed over $507 million worldwide. With Tanjiro, Nezuko, and the Hashira facing their toughest battle yet, fans are eagerly awaiting the final chapter of this demon-slaying saga.
