A listing on The-Numbers.com indicates an untitled Crunchyroll/Sony Pictures film scheduled for September 15, 2027, which has prompted speculation about its connection to the Demon Slayer franchise. Sony and its subsidiary Crunchyroll hold global distribution and streaming rights for Demon Slayer, with Aniplex, a Sony-owned subsidiary, participating in the series' production committee. The listing does not name Aniplex as the production company, leading to uncertainty about whether the project is the anticipated sequel to Demon Slayer: Infinity Castle. Industry observers note that Sony's involvement could reflect distribution terminology rather than production details. Another potential candidate for the September 2027 slot is One Piece Film: God Valley, which has been announced for a summer 2027 release. However, that film is produced by Toei Animation, a company not referenced in the listing, and Sony/Crunchyroll's distribution role in North America does not extend to France, where the listing specifies the release. The absence of definitive attribution prevents confirmation of the project's identity. Meanwhile, the first film in the Infinity Castle trilogy, Demon Slayer: Kimetsu No Yaiba The Movie: Infinity Castle, has recently become available on Hulu and Netflix. The original film concluded its theatrical run with a worldwide gross of $793 million, establishing significant anticipation for any subsequent installment.
