We are just a few days out from the release of Demon Slayer: Kimetsu no Yaiba – Infinity Castle in theaters in the United States.
If you didn’t know, the 2025 film is set to be released in American theaters starting Sept. 12. The film is an animated dark fantasy action film based on the “Infinity Castle” arc of the 2016–20 manga series Demon Slayer: Kimetsu no Yaiba by Koyoharu Gotouge. This is the first part of a two-part film. While there isn’t an official release date for the second part, fans speculate that it will be released in 2027.
If you aren’t aware by now, Demon Slayer is a franchise that started as a manga and then became an anime. Movies were later made to depict certain arcs from the books that were, more often than not, omitted from the anime. If all of this is piquing your interest and you want to get in on all the Demon Slayer goodness, why not begin by reading the manga? Multiple volumes are available to shop right now on Amazon.
