10 Must-See Demon Slayer Infinity Castle Fights That Will Leave You Speechless

by

On September 12, 2025, the first part of “The Movie: Infinity Castle,” originally known as “Demon Slayer: Kimetsu no Yaiba The Movie: Infinity Castle,” is set to premiere in the USA. Readers of the manga are eagerly awaiting this release as they’ll finally witness some of the epic battles from the story brought to life through animation. Divided into three distinct movies, “Demon Slayer: Kimetsu no Yaiba The Movie: Infinity Castle” will focus on the Demon Slayer Corps battling Muzan and the remaining Upper Moon demons, who are renowned for their immense power under Muzan’s command. A sneak peek of these powerful demons was already given in “Demon Slayer: Kimetsu no Yaiba The Movie: Mugen Train,” where Flame Hashira Rengoku sacrificed himself to protect Tanjiro, Zenitsu, and Inosuke from Upper Rank Three Demon Akaza.

Because the film “Demon Slayer: Kimetsu no Yaiba The Movie: Infinity Castle” is being divided into three parts, not every fight will be concluded in the initial release. Instead, several battles like Zenitsu against Kaigaku, Shinobu against Douma, Tanjiro and Giyu versus Akaza will be established and further developed in the first movie. These encounters are sure to be intense due to their high-action content, yet they will also evoke strong emotions as viewers delve deeper into the characters’ backstories. With the first movie set to release soon, manga enthusiasts are eagerly awaiting the animated adaptation of their beloved Infinity Castle Arc fights, presented in top-notch animation quality.

Mitsuri Kanroji and Obanai Iguro VS. Nakime

As the Infinity Castle Arc unfolds, viewers catch a peek at Mitsuri and Obanai’s adversaries. Interestingly, Nakime, who now owns the Infinity Castle, manages the labyrinth within it. She possesses this power through her biwa (traditional Japanese lute) and bachi pick. This instrumentation allows her to manipulate the Infinity Castle’s operations.

Now, every Demon Slayer has learned about Shinobu’s demise, which signifies the first Hashira death during the Infinity Castle Arc. This tragic event stirs up the determination among the surviving Demon Slayers to make sure Shinobu’s sacrifice was not in vain. Compared to other battles, this one seems somewhat more cheerful due to Mitsuri’s comedic antics during the fight, providing a refreshing change from the intense tension of previous fights. Moreover, although Nakime’s abilities aren’t often showcased, her prowess in controlling her domain becomes evident in this battle, demonstrating just how formidably skilled she truly is.

Despite Nakime not being a combative demon, she’s still quite challenging to deal with. This underscores the strength of the Upper Moon demons because even Nakime, who isn’t as combat-oriented as her peers, poses a significant threat. The confrontation with Nakime is crucial due to her authority over the Infinity Castle, which gives demon slayers a substantial disadvantage. Altering the control she has over this castle can significantly impact the course of other battles since demons have an upper hand when fighting within it.

Zenitsu Agatsuma VS. Kaigaku

In the Infinity Castle Arc, the skirmish between Zenitsu and Kaigaku stands out as one of the earliest fights with deep emotional resonance due to their shared past. Their connection runs so deep that their confrontations are among the most personal and heated. The tragic backstory is that Kaigaku’s betrayal led their former master, Jigoro, to take his own life in shame and despair over a student turning into a demon. Jigoro didn’t die quickly but endured a slow and agonizing demise. It’s no secret that Kaigaku has abandoned his humanity for power, and Zenitsu has come to terms with this harsh reality at this point in the story.

Since this fight is so emotionally intense, it makes their encounter between the two ex-students even more gratifying. The way Kaigaku openly disregards his former master and peers demonstrates just how little respect he has for them. Even as a human, Kaigaku’s arrogance mirrored that of a demon, fitting perfectly with his character. After transforming into a demon, Kaigaku didn’t alter his behavior drastically, as he had always valued power and control more than kindness and understanding.

This clash between Kaigaku is driven by rage, shock, and sadness. Despite having been classmates and when Kaigaku was still human, Zenitsu and Kaigaku had never seen eye to eye. Their talents were comparable, given they both learned under the same master. However, Kaigaku’s advantage as a demon makes his regenerative and physical abilities significantly surpass those of Zenitsu.

Shinobu Kocho, Kanao Kocho and Inosuke Hashibara VS. Douma

It’s common knowledge that Shinobu harbors a deep-seated animosity, one she’s held for quite some time, as Tanjiro points out at the start of the series. Shinobu is known for being tenacious and guided by her personal ambitions, which earns her respect among viewers as one of the most respected hashira. While she may not be the strongest in terms of breathing technique or physical power compared to other Hashira, she stands out as the smartest member of the group. After Kanae’s passing, Shinobu made it her mission to eliminate Upper Rank Two Douma and has been slowly administering wisteria extract into his system.

Shinobu lays out specific terms for Kanao should they meet Douma, which include Shinobu sacrificing herself in a grisly manner. Given this grim prospect, Kanao is determined to prevent it at any cost. She understands that if Shinobu crosses paths with Douma, Kanao must be present to help them defeat Douma without causing Shinobu harm. In the labyrinthine Infinity Castle, many demon slayers are scattered apart, making time a critical factor in their struggle.

From my perspective, the heartfelt conversation between Shinobu and Kanao regarding Douma sets the stage for their encounter within the Infinity Castle Arc. Given how deeply personal this conflict is, it’s no wonder that their battle against Douma turns out to be incredibly intense and urgent. Both Kanao and Shinobu harbor a fierce vendetta towards this Upper Rank demon, a sentiment that seems entirely justified considering he was the one who took Kanae’s life. The addition of Inosuke to the mix only serves to heighten the chaos, making their fight one of the most memorable in the Infinity Castle Arc due to its unpredictable nature.

Tanjiro Kamado and Giyu Tomioka VS. Akaza

Engaging in a thrilling dance of combat against Upper Demon Three Akaza, I found myself utterly captivated by this intense skirmish – one of the most memorable battles within the arc. Though fans have witnessed Akaza’s fighting prowess in “Demon Slayer: Kimetsu no Yaiba The Movie: Mugen Train”, it wasn’t until now that he was truly pushed to unleash his full potential. With an astonishing regeneration speed, immense durability, breathtaking agility, and overpowering strength, Akaza proved to be a formidable adversary. However, our duo – Giyu and Tanjiro – held the upper hand thanks to their strategic advantage in numbers and intimate knowledge of each other’s fighting styles. Furthermore, they shared the unique bond of having been trained under the same master, allowing them to anticipate and counter one another’s moves with remarkable precision.

I can’t help but feel a surge of animosity towards Akaza, given his heinous act of taking away a cherished character. Yet, it’s not entirely unexpected that such a person would be merciless, even while exuding an unnerving charm when interacting with potential powerful demons. In the upcoming clash between Tanjiro and Giyu against Akaza, who’s going solo, it’s clear they’ll face a tough battle. However, their struggle only amplifies the thrill of this fight, leaving us fans questioning just how much more they’ll be pushed to their breaking points by this formidable adversary.

Among other demons, Akaza exhibits an unusual form of compassion towards his adversaries, showing favoritism towards those who display strength. He frequently tantalizes powerful demon slayers he deems promising with power, as shown in “Demon Slayer: Kimetsu no Yaiba The Movie: Mugen Train” when he presents Rengoku with the opportunity to become a demon. His banter is part of his tactic to belittle his opponent, which can be perceived as a direct insult by any demon slayer. Akaza’s character stands in stark contrast to those of Giyu and Tanjiro, making their confrontation an exciting spectacle for fans.

Muichiro Tokito, Genya Shinazugawa, Sanemi Shinazugawa and Gyomei Himejima VS. Kokushibo

This upcoming battle with Kokushibo is bound to leave many spectators awestruck. Given Kokushibo’s immense power, it’s no wonder that this fight promises to be not just thrilling but also mind-blowing, as Kokushibo stands out as the strongest Upper Demon. His demonstration of power is awe-inspiring and nerve-wracking, more so because he employs breathing techniques similar to those used by demon slayers, albeit with much more devastating effects due to his demonic abilities. As Yoriichi’s brother, Kokushibo exhibits the prowess of a skilled demon slayer’s breathing technique, coupled with the resilience and strength characteristic of powerful demons.

In the Infinity Castle Arc, the battle between Kokushibo, a formidably powerful demon second only to Muzan, promises to be exceptionally violent for fans. Given that Kokushibo’s might is such that a single mistake could lead to instant death for the demon slayers facing him, it’s not surprising that they resort to all their strategies and techniques in an effort to defeat him. Despite the seemingly impossible odds, these demon slayers never waver, consistently giving their utmost when confronting demons.

In this critical battle, realizing his overwhelming power, yielding is instantly fatal. This precarious scenario elevates the fight to the most compelling in the series. Members of the Demon Corps draw courage from teamwork, a key factor in their survival against adversaries that are naturally stronger. This underscores the incredible might of the Demon Corps and their endurance over time despite the demons’ inherent strength. Based on loyalty, trust, and unity, they amplify their power and chances of surviving encounters with terrifyingly strong demons.
