Demon Slayer: Infinity Castle Movie Must Do One Thing Better Than the Manga

by

Fans in Japan have already seen the much-awaited “Demon Slayer: Infinity Castle” movie, but international viewers must wait a while longer to witness this incredible series on the big screen. Following Season 4 of the anime, based on the Hashira Training Arc from the manga, Ufotable declared a trilogy to wrap up the story. The final installment of the Hashira Training Arc laid the groundwork for the upcoming arc as the Demon Slayers confront Muzan before being drawn into the Infinity Castle. The film will arrive in U.S. theaters on September 12th, 2025, marking the beginning of the final battle against the Upper Moons. Originally established over a thousand years ago, the Demon Slayer Corps aimed to end Muzan’s reign of terror and eliminate all demons from the nation.

Muzan, transformed into a demon, has eluded the sun and human detection for centuries due to his powerful status as a progenitor. Even if the Demon Slayer Corps managed to locate him, they could not defeat him. The only known exception was Yoriichi Tsugikuni around 500 years ago, but Muzan escaped and made himself harder to find. Kagaya then laid a trap for this villain, initiating the Infinity Castle Arc. Although this storyline is exciting, the manga’s emotional flow could use improvement, which may be addressed in upcoming anime films.

Demon Slayer’s Infinity Castle Arc Didn’t Originally Have Enough Emotional Payoff

What made the fights in the Infinity Castle Arc of Demon Slayer stand out is that they all had a pre-existing context or buildup. Most characters battled demons they shared some kind of history with, which not only amplified the combat intensity but also the risks, as the Demon Slayers were compelled to defeat these monsters. Characters like Shinobu, Zenitsu, Tanjiro, Giyu, and many others not only worked together for a common objective, but also pursued personal vendettas. These character pairings are why each fight was rich in emotional moments, contributing to the heightened tension of the arc.

In essence, this implies that there will likely be some sad events unfolding as the Demon Slayer Corps confronts Muzan and the Upper Moons – a battle that stands as the toughest in their history. Regrettably, the manga’s progression felt hurried, making it hard to absorb the intense moments. One instant we witness Shinobu in a heart-wrenching battle, only for the focus to swiftly shift to another character in quick succession. The narrative perspective often jumped from one character to another in brief intervals.

As a devoted fan, I can’t help but feel a tad disappointed with the pacing in the latter part of “Demon Slayer.” The battles and emotional moments seemed to pass by in a flash, not leaving as lasting an impact as I had hoped. The transition from the battle to the epilogue felt abrupt, almost as if the manga was rushing through the heart-wrenching tragedies that unfolded during the fight. This hasty progression somewhat muted the weight of the sacrifices made by our characters, a factor that may have contributed to the criticisms leveled at it when it first came out.

Ufotable Can Still Save Demon Slayer’s Final Arc

I’ve witnessed on numerous occasions how Ufotable skillfully amplifies the epic narrative of Demon Slayer. One such instance is the Infinity Train film, which, though it encompassed only a handful of manga chapters, was transformed into a true work of art by the animation studio. The story remained untouched, but the emotional beats were stretched out, making all the difference. By the end of the film, fans found themselves moved to tears by Rengoku’s poignant goodbye. It’s crucial that Ufotable handles the final arc with equal care and attention, as the farewells and backstories should carry significant emotional weight.

The studio could devote extra attention to each character, enhancing their representation beyond the manga. If the anime takes its time not with the narrative but in how it presents these moments, it can transform rushed scenes into memorable ones. Readers of the manga are aware that the Infinity Castle arc is the most intense and exhilarating part of the story, which means anticipation is higher than ever. Fortunately, Ufotable possesses the skill to execute this masterfully.
