Demon Slayer: Kimetsu no Yaiba is totally a big deal in the anime world, breaking records and blowing everyone’s minds. Now, with the news of the new Demon Slayer: Infinity Castle movie trilogy coming up, fans are super hyped.

Given the overwhelming success of Demon Slayer: Mugen Train, which became the highest-grossing anime film of all time, even surpassing Hayao Miyazaki’s Spirited Away. Now, everyone’s tuning in to watch Infinity Castle to see if this initial film of the trilogy can break its own record and revolutionize the game for anime in world cinema once more.
The phenomenon of Demon Slayer: From manga to global sensation
When Demon Slayer: Kimetsu no Yaiba, written by Koyoharu Gotouge, initially aired as an anime series in 2019, it gained popularity instantly, with its beautiful animation, heartwarming story, and endearing characters capturing the hearts of the viewers.

Ufotable’s animation prowess raised the bar for the industry, and the series became a work of art. The franchise got to a new height with the release of Demon Slayer: Mugen Train in 2020, which became the highest-grossing anime film of all time and grossed over $507 million worldwide, surpassing Hayao Miyazaki’s Spirited Away released in 2001.
With Infinity Castle on the horizon, the series is gearing up for an even greater movie domination. The Infinity Castle arc is genuinely one of the most action-packed and dramatic storylines in Demon Slayer, serving as the climactic battle against Muzan Kibutsuji and the Upper Moons. With three movies planned, the trilogy will break down the final manga arc into a cinematic experience unlike any other anime adaptation.
Can Infinity Castle break Mugen Train‘s record and challenge Hayao Miyazaki’s legacy?
Hayao Miyazaki may have pioneered the genre’s cinematic success, but Demon Slayer is here to set the new gold standard. If history is any indication, Demon Slayer: Infinity Castle can easily surpass Mugen Train‘s record-breaking box office numbers.

The first movie is dropping in Japan on July 18, 2025, and it’ll hit global theaters in August, with U.S. and Canada showings kicking off on September 12, 2025. Everyone’s really looking forward to this release since it’ll be available in Japanese with English subtitles and also an English dub.

Moreover, Ufotable has made sure that the film will be optimized for IMAX and premium formats so that the fans are able to experience the full glory of the demon fights and emotional narrative on the big screen. The audio and music, which were composed by Yuki Kajiura and Go Shiina, will also add to the intensity of every fight scene and emotional moment.
There are several reasons why Infinity Castle is likely to be the highest-grossing anime movie in history. The anime fan base has expanded tenfold since Mugen Train, so the potential size of the audience is even larger now. Since Infinity Castle is split into several films, each film can surpass the last one’s box office.
So after all these analyses, the main question remains: with Mugen Train making history by grossing over $507 million worldwide, could Infinity Castle push past the $600 million mark? Given the excitement surrounding its release, the possibility remains very high.
Demon Slayer: Kimetsu no Yaiba series and Mugen Train movie are available to watch on Crunchyroll and Infinity Castle will also be available on the same platform.
