Through a sensational “Infinity Castle Arc” trailer, revealing high-octane animation sequences,Demon Slayer: Kimetsu no Yaibaonce again reminds the franchise’s worldwide audience of why the anime is a cinematic masterpiece — standing tall among unforgettable entertainment blockbusters. The highly anticipated movie revolves around three high-stakes fights that will impact the story’s underlying narrative profoundly.
However, lurking beneath fans' enthusiasm to witness the movie’s cinematics is a possible dealbreaker thatDemon Slayerfilmmakers need to overcome. The originalDemon Slayermanga series had pacing problems, concluding the story in an abrupt, jarring manner that failed to flesh out the plot satisfactorily. Now, all hopes rest on the theatrical Infinity Castle trilogy to remedy this flaw, not escalate it.

With Three High-Stakes Battles At The Movie’s Epicenter, Pacing Might Be A Problem
The Pacing Problem Is Glaringly Apparent In The Manga
One setback holding theDemon Slayerseries back from pristine perfection is pacing; even themanga struggles with this problem. Concluding in May 2020, theDemon Slayerseries wrapped up the story with 205 chapters — a surprising number, considering the plot depth and character variety present in the story’s final arc.
Fans with keen eyes would have discovered howDemon Slayer’srecent installments subtly rush through battles, character reveals, and critical developments tied to the heart of the story. This problem emanates from the manga that underutilizes the final arc’s potential by lowering the curtain prematurely on pivotal fights that determine its trajectory.

Alarmingly, theInfinity Castle Arc is at the coreof this problem, and the upcoming movie trilogy will have to innovatively adapt the battles in a way that resolves the lapses originating from the manga.The major highlight is the three anticipated clashes, starring Tomioka Giyu & Tanjiro’s battle with Akaza, Zenitsu’s vengeful fight with Kaigaku, and Shinobu’s skirmish with Doma.
These battles are unavoidable steps theDemon SlayerCorps must take to reach Muzan. Thankfully, viewers already have a solid connection to the battling characters the movie brings to the big screen. Still, the problematic battles are not far off, as they will slowly creep into the trilogy over the course of its full run.
The manga resolves significant battles in the Infinity Castle Arc underwhelmingly. Although it hosts flashy fights and memorable events that manga readers will forever treasure, it fails to extensively introduce readers to major characters in the arc.
Addressing The Pacing Issue Should Be Among The Film Creators’ Priorities
Sometimes, Necessary Tweaks Are Needed To Propel An Adaptation Towards Greatness
To fully immerse themselves in a story, viewers need to be connected to both heroes and villains. It gives the fictionalized expression depth and relatability, forming a genuine emotional connection that guarantees lasting effects on viewers' minds long after the screen turns blank.
In this regard,Demon Slayer’sfinal arc is sorely lacking, and this problem is exacerbated by the story’s hurried approach to the series’ titular antagonist, Muzan. Once the battle line with Muzan is drawn, the story strides heedlessly towards the demon, neglecting focal factors that elevate the story’s worth.
Demon Slayer: Infinity CastlePart I will debut much earlier in Japan on July 09, 2025. On the contrary, US and Canadian audiences will be able to stream the film on Crunchyroll on June 18, 2025.
In some situations,compromising on the faithfulness of a manga adaptation may be necessaryto redeem the unsatisfying aspect of the original work. On a glaring note, theDemon Slayerpacing problem tightly fits into this necessity.
To address this adjustable problem, the “Infinity Castle Arc” needs to take a measured approach to its climactic battles, allowing viewers to connect with characters and central developments before serving them electrifying battle sequences. Together, both elements are a surefire winning formula that will guarantee the unarguable success of Ufotable’s tripartite movie approach to the arc.
