Toho Execs PredictDemon Slayer’sInfinity Castle Films Will Be the Most Successful Yet
The Trilogy Is Already Predicted To Surpass the Studio’s Current Top Film,Your Name
According toa post on Mantan Web,Demon Slayer’sInfinity Castle trilogyis predicted to not just rule the theatrical box office when it releases, but completely change it forever. PastDemon Slayermovies that have hit theaters have been immensely successful, earning some of the highest revenues of any anime films ever, so it is no surprise that the upcoming trilogy is anticipated to shake up the box office completely. Executive Managing Director Ichikawa Minami commented that"the film industry’s box office revenue for this year, including both Japanese and foreign films, will be “around 200 billion yen.”
Of this 200 billion yen, Minami predicts that Toho, the studio making theDemon Slayerfilms, will be responsible for 91 to 92 billion of those yen, which is a staggering percentage. Toho has had quite a few hit films lately, includingYour Name,which was the company’s highest-earning film ever at 85.4 billion yen.The studio has proven their reliable track record for creating films that fans adore, and with a massive franchise likeDemon Slayerin their hands, it is no great shock that the Infinity Castle trilogy is predicted to carry the 2025 box office on its shoulders.

Demon Slayer Mugen Train Already Changed the Anime Industry Forever
Mugen Train Altered How Studios Approach Anime Movies
Demon Slayer’s first movie,Mugen Train, was a bold experiment in one particular way: it was a canonical film to the main series, continuing the story that had been told in the TV anime. For decades, most anime movies have been side stories at best, like theMy Hero Academiafilms, or outright non-canonical, like the numerousDragon Ballfilms of the 1990s. This was largely done in order to reach as wide an audience as possible, allowing those who are only vaguely familiar with the franchise in question to enjoy the movies on the same level as the most dedicated fans.
Mugen Train, however, was a direct continuationof the anime’s story–the final scenes of season 1 are the first scenes of the new film, connecting them. This approach allowed them to take a very dramatic, fairly stand-alone arc of the story and give it the Big Screen treatment, enhancing the quality of the animation and storytelling to film levels.Demon Slayer’s success with this approach inspired other series to attempt the same, such as withJujutsu Kaisen 0and the upcomingChainsaw Manmovie. EvenDragon Ballhas gotten in, withSuper Heroconsidered a canon continuation ofDragon Ball Super.

The once-unthinkable canon anime film is now quickly becoming standard practice, all because ofDemon Slayer’s success withMugen Train. Taking the most important story arcs and giving them the high quality that a film needs to succeed is definitely winning over fans, and it’s proven that, provided the arc can stand on its own, it has little impact on non-fans seeing the film.
