Fans eagerly awaiting the next major installment in the acclaimed *Demon Slayer: Kimetsu no Yaiba* saga have just received confirmation regarding its sheer scale, at least in terms of screen time. The upcoming feature film, *Demon Slayer Movie: Mugen Jou-hen* (also known as the Infinity Castle arc), is set to run for a substantial duration, positioning it among some of the lengthier cinematic experiences in recent memory.
The official runtime for the film has been confirmed at 155 minutes, which translates to 2 hours and 35 minutes. This figure is noteworthy on its own, but it gains particular perspective when placed alongside major live-action blockbusters.
To provide a comparative benchmark relatable to a global audience, this runtime surpasses that of not just one, but two significant entries in the Marvel Cinematic Universe. *Avengers: Infinity War*, a film known for its sprawling narrative and massive ensemble cast, clocked in at 149 minutes. Its predecessor, *Avengers: Age of Ultron*, was shorter still at 141 minutes. It appears *Demon Slayer: Infinity Castle* is prepared to hold its own against Earth`s mightiest heroes, at least in terms of willingness to occupy audience attention for an extended period.
For those unfamiliar with the source material, *Demon Slayer: Kimetsu no Yaiba* originates from a highly successful manga series set in early 20th century Japan, where swordsmen battle man-eating demons. The anime adaptation, which first premiered in 2019, has garnered widespread critical and commercial success worldwide. The `Infinity Castle` arc represents a pivotal and climactic section of the original manga story.
The decision to allocate 155 minutes to this segment suggests a commitment to thoroughly adapting the intense battles, critical character developments, and significant plot revelations contained within the `Infinity Castle` narrative. This extended duration potentially allows for a more complete and detailed rendition of the arc`s events than might be possible with a shorter theatrical cut.
The *Demon Slayer: Infinity Castle* movie is currently scheduled for release on September 12, 2025. With a runtime that confidently steps into the territory of major Hollywood epics, anticipation for this key chapter in the *Demon Slayer* story continues to build.
