The third episode of the fourth season of “Demon Slayer: Kimetsu no Yaiba” generated intense debate among fans due to its peculiar adaptation of the original manga. This episode of just over twenty minutes adapted just one and a half pages from chapter 132 of the manga.surprising fans and critics.

Since the announcement of the fourth season, titled “Demon Slayer: Kimetsu no Yaiba Hashira Training Arc”, fans already suspected that there would be a lot of original content. This arc of the manga consists of only nine chapters, which made many wonder how an entire season of the anime would be filled.

Reactions to this decision Ufotable They were mixed. On the one hand, some praised the producer for its ability to expand the narrative with original materialhighlighting the quality of the animation and the additional depth given to the characters and world of “Demon Slayer”. They argue that the studio is using its creativity to enrich the series, offering more content to fans eager for more adventures of Tanjiro and his friends.

On the other hand, some critics and fans are unhappy with this approach, accusing Ufotable of “tighten” the original work to maintain fan interest with episodes full of non-canon content. These detractors believe that the series should properly advance the main story, rather than insisting on additional scenes that do not appear in the manga. For them, this method dilutes the essence and rhythm of the original narrative, creating a less satisfactory experience for the viewer seeking a faithful adaptation.

This controversy highlights a common dilemma in anime adaptations: finding the balance between being faithful to the source material and creating new content that keeps the audience interested. While some like the expansion of the “Demon Slayer” universe, others prefer that the series remains more faithful to the pace and content of the original manga.

• «Honestly, I'm fine with that. While Tengen has had enough development already, I have no problem with having a full episode for each of the Pillars.».
• «Wow, they're really expanding the content to fit into one season. Reminds me of the early days of Naruto Shippuden».
• «No wonder it was so boring. Why couldn't they just do this arc in about three episodes and move on to the next one?».
• «And like, why do they do that? It's not like the manga is in publication».
• «And the episode was enjoyable. The interactions, dialogue, animation, and foreshadowing were perfect. I'm really enjoying this season because I've always wanted to see all the Pillars before the next arc.».
• «This is why the anime Kimetsu no Yaiba is far superior to the manga».
• «They created a full day of training with Uzui that will be memorable forever.».
• «One of the best original episodes ever».
• «And what's the point? The original manga was finished years ago.».
• «So does this mean they will only adapt eight chapters of the manga and then we will have to wait another year?».
• «I don't understand anyone who says this episode was boring.».
• «Just like with Shingeki no Kyojin, they are tightening Kimetsu no Yaiba».
• «It amuses me to see people hate this, but when it happens with Jujutsu Kaisen all the idiots come out to applaud MAPPA and lick their feet. Fights that never happened, prolonged moments, but of course, “Jujutsu Kaisen is the best in the world”».
• «Satoru Gojo's past arc has the same number of chapters as this one and Jujutsu Kaisen did an amazing job adapting it in the second season. They had no reason to stretch this arc considering the next one is the last one.».
• «They're just taking the time to release more movies and seasons at this point. This could have easily been adapted into 3 or 4 episodes in a season of around 26 episodes.».
• «I didn't even realize it was original content, it was just too good! I'm glad you took the time to rekindle the relationship between Tengen and Tanjiro, I've missed him so much!».
• «This is a great example that adding original content to an adaptation doesn't always have to backfire. It reminds me of when Chainsaw Man did the same thing.».
• «This is all Koyoharu Gotouge's fault. At this point the manga started to get extremely rushed, it was at this time that it was learned that the author had a sick family member and this caused the decline in both art and narrative quality.».
