Demon Slayer’s ‘Infinity Fortress Arc’ to adapt into trilogy movie? Here’s what we know so far

Demon Slayer Season 4 is one of the most anticipated anime seasons. When fans were busy worrying about the series’ fate with the Hashira Training arc, something utterly unexpected happened within the show’s studios. This is about the adaptation of the manga’s longest arc, the Infinity Castle arc. While Season 4 is set to be released next year, Studio Ufotable appears to be planning a number of other projects to follow.

The Infinity Castle is the longest story arc for Demon Slayer, according to manga readers. It is also understood that the arc may require several seasons to cover all of the subplots. This week, the Twitter leaker page Oecuf confirmed that Ufotable has sealed down the decision to work on many films for the upcoming arc. The message also confirmed that Ufotable will make the official announcement very shortly.


The leaker stated in a tweet that followed that fans could expect numerous anime films, given the Infinity Castle Arc is the longest in the manga series. This covers chapters 137-180 for a total of 43 chapters. This arc concentrates upon Muzan’s one-on-one duel. The Demon Slayer Corps conducts an all-out assault on Muzan Kibutsuji’s stronghold, the Infinity Castle, from this location.

While the film appears to be in the works, fans have not forgotten about Season 4. Regardless of the other projects, the Hashira Training storyline will remain the anime’s fourth season. It is also predicted that this season will be the shortest yet. The season is planned to be released in the summer of 2024. Netflix is also anticipated to distribute all of the next season’s episodes.
