Leaks that surfaced on Weibo and other forums online are suggesting that Demon Slayer‘s Infinity Castle Arc, one of the longest arcs of the manga, will not be adapted into an anime series.
Instead, the Infinity Castle/Fortress arc will be adapted into a movie or multiple movies. Most of the leaks online have come to the conclusion that the arc will be translated into a movie trilogy for the big screen. Some even said that in order to not rush the content, atleast five movies will be needed to adapt the story properly if the Sunrise Countdown arc is also included.
However, there is no confirmation regarding any of these information right now, and it would be wise to take it all with a pinch of salt.
The movie adaptations, if true, will air after the Hashira Training arc which was announced in the final episode of Demon Slayer Season 3 – The Swordsmith Village Arc.
No official details about the Demon Slayer Infinity Castle arc movie adaptations are available right now. Even the leaks that have surfaced, aren’t very concrete, so it would be wise to wait.
While some fans greeted the leaks with excitement, saying that the movie adaptations were good hands, i.e. Ufotable, some felt that Ufotable and Aniplex were trying to milk the most out of the fan-favorite franchise.
A section of fans even felt that waiting for movies to get released will probably ruin the experience, even though it would be great to watch the fights on the big screen. There is also a high chance that anime-only fans will get spoilers for the upcoming parts, if the wait is too long, and that would kill the enthusiasm.
There were even fears of the plot being rushed, since fans felt that the Infinity Castle Arc could not be adapted properly in just a movie or even three movies.
Despite all that, there is a general consensus that if Demon Slayer‘s final arcs (including the Sunrise Countdown arc) get adapted into multiple movies, it would forever change how production studios look at anime and adaptations in general.
