Demon Slayer Infinity Castle Movie Leaked Release Date Points to September 2027

While a few months remain before 2026 ends, anime fans know they must wait until 2027 for the biggest franchises to release their next blockbusters. At the top of most watchlists is Demon Slayer: Infinity Castle 2, the sequel to the highest-grossing anime movie of all time, which still lacks a confirmed release window. Meanwhile, One Piece has announced that its next movie will arrive in the summer of 2027. This project will be the first direct tie-in with the official story of the manga and anime, titled One Piece Film: God Valley.

Eagle-eyed fans have spotted a potential specific release date for a 2027 anime movie that could be Infinity Castle 2. Movie listing sites like The-Numbers.com list an untitled Crunchyroll and Sony Pictures film slated for release on Sept. 15, 2027. Sony and its subsidiary Crunchyroll own the global distribution and streaming rights for the Demon Slayer franchise. Sony also sits on the anime production committee through another subsidiary, Aniplex.

Is Demon Slayer: Infinity Castle 2 coming next September?

The listings for this unnamed movie do not mention Aniplex as the production company, listing only Sony Pictures. This could be a clue that the movie is not Demon Slayer: Infinity Castle 2. However, because Aniplex is a wholly owned subsidiary of Sony, this could simply be a matter of terminology.

Another candidate for the Sept. 15 spot is One Piece Film: God Valley, given its announced summer 2027 release window. One Piece movies are produced by Toei Animation, and that company is not mentioned in the listing. Sony and Crunchyroll handle the distribution of One Piece movies in North America, but notably not in France, which is the country mentioned in the listing.

Overall, there is not enough information right now to guess what the mysterious Sony and Crunchyroll movie releasing on Sept. 15 is. Fans should treat this as a tease and wait for official announcements before planning to take that day off work. Meanwhile, the first movie in the Infinity Castle trilogy has just landed on Hulu in case you want to watch it again.
