Demon Slayer made history in 2025 when it debuted its final arc with the newest theatrical release, Demon Slayer: Infinity Castle Part 1 - Akaza's Return. This movie premiered in Japan on July 18, 2025, and it went on to become the highest-grossing Japanese anime movie of all time, surpassing the previous record holder, Demon Slayer: Mugen Train.
Ever since this smash-hit release, we've all been looking forward to the next big installment in the final trilogy of the franchise, that is, Demon Slayer: Infinity Castle Part 2. Over a year after the release of Part 1, Ufotable has yet to reveal the exact release date of the movie. However, a new unnamed Sony animated movie is listed for release in September 2027, and the likeliest contender to fill this spot is Demon Slayer: Infinity Castle Part 2.
Sony Pictures film is a massive Japanese-owned entertainment company, first founded in 1987. The company has been behind some insanely successful movies. In 2025, it was also behind the biggest Japanese animated movie of all time, Demon Slayer: Infinity Castle Part 1. Since the release of this successful project, Sony Pictures Film and Ufotable Studio have been rather quiet about Demon Slayer: Infinity Castle's next release, which, right now, is referred to as Infinity Castle Part 2. Unfortunately, we still have no update on its official release.
That said, on September 17, 2026, Sony Pictures officially unveiled a new movie listing. This movie is listed with no title at the moment, making it impossible to exactly pinpoint what project it is. What makes this movie undoubtedly an anime one is its listing, stating its launch on Crunchyroll, a platform exclusively focused on anime-related releases. The listing also indicates a possible release date. For the domestic market, the release date is set for September 17, 2027. Meanwhile, the international release is oddly listed on September 15, 2027. This is about the gist of the new data revealed about this movie, and most fans believe it pertains to none other than Demon Slayer's next installment, Infinity Castle Part 2.
Immediately upon seeing a new anime movie release listed by Sony for September 2027, fans immediately ran to the conclusion that it could be Ufotable’s next big hit movie: Demon Slayer: Infinity Castle Part 2. There are many reasons why this could indeed be the second of the trilogy. It has long been rumored that Demon Slayer: Infinity Castle Part 2 would be released sometime in 2027. Beyond just rumors, it is because a 2-year gap between each movie would be the perfect amount of time to wait, keeping fan interest high and ensuring enough time for a proper production. This also lines up with the major reports that the finale of the trilogy will be coming 2 years after the second movie, in 2029.
It must be mentioned that Infinity Castle Part 2 is also being released with the backing of Sony Entertainment, which owns production and distribution rights. Out of the major movies that are set to be released in 2027 under Sony, Demon Slayer is definitely the biggest of the bunch, and the one most likely for this release window. Of course, this listing is no official confirmation of Demon Slayer's return, and we'll have to wait a few more months for an official confirmation to drop during Jump Festa 2027.
Demon Slayer: Infinity Castle Part 1 was released in Japan in Summer 2025, specifically July 18, 2025. A September release might be an odd choice for Ufotable for Part 2. Ufotable knows that the summer season is the most profitable one for releasing massive hits, especially with students out of school and ready to watch their next big hit. The listing also seems to point to an almost semi-release between domestic and international audiences, which was not the case for Infinity Castle Part 1.
For the first movie, the international release started a month after Japan. There could, however, be some explanations behind these issues. For one, the September 2027 release could specifically be just for international theaters. The dates listed could still be changed, and Japanese fans could instead get the movie 2 months beforehand.
