After revolutionizing the anime industry with one of the most popular first seasons in the genre’s history (followed by five more that were just as successful) and the highest-grossing anime movie of all time, the Demon Slayer franchise is ready for the beginning of the end. Demon Slayer: Kimetsu no Yaiba Infinity Castle, the first movie in the trilogy that will close up the story of Tanjiro, Nezuko, and the Demon Slayer Corps will debut in theatres in the United States and Canada on Sept. 12, 2025, and its first explosive official trailer is here, ready to get fans hyped up for the event.
Demon Slayer: Kimetsu no Yaiba is based on the manga by Koyoharu Gotoge. The anime, produced by Ufotable, conquered the hearts of fans worldwide thanks to its beautiful visuals that complement the fast-paced story and the compelling characters of the manga. The story follows Tanjiro Kamado, a young boy who finds his family slaughtered by demons, and his sister, Nezuko, turned into one of the flesh-eating creatures. In an attempt to protect her and find the culprit behind the massacre, Tanjiro joins the Demon Slayer Corps, an organization dedicated to the eradication of demons by killing their progenitor, the elusive Muzan.
In this final trilogy of movies, Tanjiro, his companions Zenitsu and Inosuke, and the mighty Hashira (the strongest Demon Slayers) find themselves trapped inside the Infinity Castle, the demons’ stronghold, where they fight for their lives against the Upper Moons, Muzan’s strongest subjects. Exciting battles and heart-wrenching drama ensue. As those who read the manga know, no one is safe in this final battle between good and evil, and some beloved characters may not see the light of day.
It will be interesting to see if one or more of these final movies will manage to surpass Demon Slayer: Mugen Train, the unbeaten king of anime movies, which grossed over $507 million worldwide. This first official trailer shows that, as usual, Ufotable is not pulling any punches, and this will be another visual spectacle for fans.
