The popular Japanese medium Myjitsu has generated great expectations among anime fans by publishing an article about the possibility that the acclaimed adaptation of this series will conclude with a movie or a series of movies after the fourth season. This speculation arises due to the length of the last story arc of the work, which makes it difficult to decide if it will be a new season or a movie.
The third season of the anime "Kimetsu no Yaiba" concluded on June 18, and the production of a fourth season that will adapt the "Training with the Pillars Arc" was immediately announced. The next arc, "Training with the Pillars", is set in the fifteenth and sixteenth volumes of the original manga, and focuses on the group led by Tanjiro Kamado's interactions with the Pillars of Demon Slayers, preparing for the final showdown.
However, the challenge lies in the subsequent story arc, the "Infinite Dimensional Strength Arc", considered the climax of the story. Fans have expressed their desire to see it adapted into a high-quality movie, but due to its length of 69 chapters, it is a challenge for the production to decide how to bring it to the screen without sacrificing fidelity to the original manga.
The first season of the anime adapted the first 53 chapters into two cours, while a 117-minute film covered the "Infinity Train Arc," which consists of 13 chapters of the manga. Following a similar pace, it is estimated that the "Infinite Dimensional Fortress Arc" could be split into two parts, a two-court TV series followed by one or two movies.
"Kimetsu no Yaiba" is an extremely popular franchise internationally, with performance tours and events all over the world. The interest in the series is such that streaming platforms like Crunchyroll have struggled to handle the demand from viewers looking to see the season three finale.
In view of its global relevance, it is likely that the production will consider releasing the second part of the "Infinite Dimensional Fortress Arc" simultaneously in different territories, which would be an unprecedented event. However, it is not yet confirmed if the final arc will be completed solely with a theatrical release, as it could follow the lead of the "Infinity Train Arc", which transitioned from a movie to a TV series.
In conclusion, Ufotable, the company responsible for the production of "Kimetsu no Yaiba", is already announcing new projects, but the pace of production and future plans are still unclear. Fans are eagerly awaiting how this successful franchise will play out in the future.
