Possible Leak Reveals Release Date for Demon Slayer: Infinity Castle

The announcement of the Demon Slayer: Infinity Castle movie has generated immense excitement among anime enthusiasts, with many anticipating its release in 2025. Recent hints from Sony suggest that the film’s launch date may have been inadvertently revealed, adding to the buzz surrounding this highly awaited sequel to the Demon Slayer: Hashira Training Arc, which marked the latest season of the series on television.

When the Demon Slayer anime first premiered, it included a 26-episode season alongside the blockbuster film, Mugen Train. This film achieved remarkable success, becoming the highest-grossing movie ever in Japan and later securing its position as the all-time top-grossing Japanese film internationally. Following this triumph, more sequels were announced to fully explore the manga storylines yet to be adapted into the anime.

Upcoming Infinity Castle Movie Details

The Infinity Castle film will kick off a trilogy that adapts the penultimate arc of the Demon Slayer series. Currently, details regarding the titles of the subsequent two films remain undisclosed, but there is significant anticipation from both the fan base and the production team, given the franchise’s immense popularity.

Speculation is rife that the Demon Slayer: Infinity Castle Arc may premiere in theaters on September 12, 2025.

While official announcements have indicated that the movie is slated for release sometime in 2025, a recent listing on the French Sony Pictures website showcased an ‘Untitled Sony/Crunchyroll/Aniplex event film’ with a potential debut date of September 17, 2025. While this entry was later removed, it raised eyebrows given that few titles are as monumental as Demon Slayer to warrant being labeled an “event film.”

Multiple movie databases have also featured listings for the film, and according to sources including The Numbers, it is expected to reach audiences in the United States and the United Kingdom on September 12, 2025.

A simple Google search for the “Untitled Sony/Crunchyroll/Aniplex event film” will reveal several other sites citing this movie alongside its rumored release date, although many of these listings have also been removed.

Adding to the speculation, German cinema chain CineStar previously listed this unnamed film with a description tying it to the Infinity Castle Arc. Despite the eventual removal of this page, several users captured screenshots that solidified the rumor:
