Demon Slayer Infinity Castle Arc release date leaked only. Here's what we know

A potential release date for the highly anticipated "Demon Slayer: Infinity Castle Movie" has surfaced, pointing to a Fall 2025 premiere. The movie, continuing the story from the "Hashira Training" arc, is expected to resolve the cliffhanger ending of the previous season.

A listing on German CineStar, a cinema chain, shows an "Untitled Crunchyroll/Sony/Aniplex Event Film" described as the "Kimetsu no Yaiba 'Infinity Castle Arc' Movie" with a September 25, 2025 release date in Germany. This follows a now-deleted listing on Sony's website with a similar description. Social media fan pages are buzzing with speculation based on these listings.

The movie follows Tanjiro Kamado's journey as a demon slayer. Crunchyroll’s official synopsis states, “It is the Taisho Period in Japan. Tanjiro, a kindhearted boy who sells charcoal for a living, finds his family slaughtered by a demon. To make matters worse, his younger sister Nezuko, the sole survivor, has been transformed into a demon herself. Though devastated by this grim reality, Tanjiro resolves to become a “demon slayer” so that he can turn his sister back into a human, and kill the demon that massacred his family.”



The "Infinity Castle Arc" sees Tanjiro and the Hashira facing Muzan Kibutsuji inside the Infinity Castle. Haruo Sotozaki is directing the film, with Akira Matsushima as Chief Animation Director and Character Designer. Yuki Kajiura and Go Shiina are composing the music.

Previous seasons of "Demon Slayer" are currently streaming on Netflix, JioCinema, and Crunchyroll.

Since its debut in 2019, Demon Slayer has become a global phenomenon, breaking numerous records and earning widespread acclaim. Its earlier films, particularly Mugen Train (2020), achieved unparalleled success, with Mugen Train grossing over $473 million worldwide, making it the highest-grossing anime film globally. The film's remarkable success was underscored by its 98% rating on Rotten Tomatoes, cementing its place in anime history.

This final arc is set to bring Demon Slayer to a thrilling conclusion, following Tanjiro's long journey to cure his sister Nezuko, who was transformed into a demon. The Infinity Castle arc is anticipated to be the most significant chapter yet, with action-packed sequences and emotional moments that will resonate with the millions of fans worldwide.
