The Demon Slayer anime series is nearing its end with the highly anticipated movie trilogy that will bring the Infinity Castle arc to life on the big screen. This arc is set to deliver some of the most intense battles and emotional confrontations the series has ever seen. Known for its beautifully animated fight scenes and rich character development, Demon Slayer's Infinity Castle movie trilogy will not disappoint in delivering some of the most hype moments fans are looking forward to.

The Infinity Castle arc will push the main cast of demon slayers to their highest limits, both physically and emotionally. From epic fights between the Hashira and Upper Moons to the reveal of new abilities and techniques, this trilogy is sure to keep fans on the edge of their seats.

10 Seeing New Techniques Animated

One of the key factors behind Demon Slayer's massive popularity is Ufotable's breathtaking animation, which consistently elevates the series' action scenes to an unparalleled level. Fans widely consider Demon Slayer to be one of Ufotable's best anime, and it's easy to see why just on an animation level. In the Infinity Castle trilogy, fans will see new blood demon art like Doma’s cryokinesis and Kokushibo’s moon breathing come to life. Paired with the studio's mastery of fluid motion and dynamic effects, these new techniques are bound to create some of the most hype-inducing moments in the trilogy.

Fans will also see new breathing styles and techniques that haven't yet been animated, such as Kanao's flower breathing that she uses in her fight against Doma. Seeing all the new techniques will give fans a chance to witness the true strength and abilities of each character.

9 The Ubuyashiki Siblings Finally Get to Shine

After the death of his father, Kagaya Ubuyashiki, his mother Amane, and his two sisters, Hinaki and Nichika, Kiriya becomes the next leader of the Demon Slayer Corps at only eight years old. With the help of his sisters Kuina and Kanata, the remaining Ubuyashiki siblings get a chance to showcase their incredible memorization skills, which help map out and guide the demon slayers through the constantly changing infinity castle.

Their moment to finally shine is one of the more underrated moments in the Infinity Castle arc, but the role they play is crucial and serves as the backbone to the many battles fans will see. Without Kiriya and his sisters, the odds of survival in the Infinity Castle would be nearly impossible. Despite the grief of losing their parents and siblings in Demon Slayer's newest season, Kiriya and his sisters did not waver. They understood the weight of their duty and their unwavering resolve proves the determination they have to carry on their family’s legacy and help the Demon Slayer Corps finally defeat Muzan.

8 Hashiras Awakening Their Demon Slayer Mark

A hype moment fans can look forward to is seeing other Hashiras awaken their Demon Slayer Mark, a unique ability that manifests during the midst of an intense battle. This mark appears as a distinct design on the skin and grants the user enhanced strength, speed, and endurance. This incredible power plays a crucial role in some of the most iconic fights in the arc.

More than just the mark itself, the ability also turns the user’s Nichirin blade red for a certain amount of time, making it a far more effective weapon that can weaken a demon's regeneration and inflict greater damage. Seeing the Hashira wield these new abilities will be a highlight for fans as it will add an extra layer of intensity to the already epic fights.

7 Muzan's Final Form

For much of the series, Muzan's reputation as Demon Slayer's first and strongest demon has been more of a looming threat than something actively witnessed in combat. Fans have yet to see him truly unleash his abilities in battle against the Demon Slayers. Muzan has mostly stayed in the shadows, using his Twelve Kizuki to do his work, but the Infinity Castle arc changes all of that. Unfortunately for Tanjiro and the rest of his team, Muzan truly lives up to his reputation.

In this arc, Muzan's final form will be revealed along with the full extent of his deadly abilities that truly solidify him as the series' main villain. The intense battles against Muzan in his final form will not only highlight why he's the most feared demon, but will also push the Demon Slayers to their absolute limits, making it one of the most epic and anticipated showdowns in both the arc and in the entire series.

6 Obanai and Mitsuri vs. Nakime

Though Obanai and Mitsuri's battle against Upper Moon Four, Nakime is more of a cat-and-mouse game than a direct battle, it will still be an opportunity to see more of these two Hashira in one of the Infinity Castle Arc's best battles. Obanai and Mitsuri's dynamic will work together using their Snake and Love Breathing techniques to counter Nakime. While the fight might lack the intensity other battles have, it highlights the bond Obanai and Mitsuri have and gives fans a much-anticipated look at what their chemistry looks like in battle.

After taking the place of Hantengu as Upper Moon Four, Nakime plays a crucial role in Muzan's plans by manipulating the entire layout of the Infinity Castle. Nakime can manipulate doors, hallways, and rooms, turning the battlefield into a constantly changing maze, making it incredibly difficult for her to be cornered or attacked. Despite the indirect nature of the fight, the challenge Nakime presents adds an extra layer of difficulty, as Obanai and Mitsuri must rely not only on their skills but on their trust in each other to survive.

5 Shinobu Finally Gets Her Revenge

Shinobu’s battle against Upper Moon Two, Doma, is deeply personal, as he is the same demon who killed her older sister, Kanae. Seeing that Doma is the demon Kanae described in her last moments of death, Shinobu becomes enraged and attacks him with her Insect Breathing and poisonous techniques. Though she ultimately dies at Doma's hands, her relentless effort plays a crucial role in his downfall. Even though she doesn’t get to land the final blow, it’s her poison that paves the way for his defeat.

In her final moments, Shinobu entrusts her successor, Kanao, with the task of finishing what she started. After Doma's death, he meets Shinobu in the afterlife as she holds his decapitated head. Shinobu smiles at him and expresses her relief that she can finally pass in peace knowing Doma is dead. Despite not being able to kill Doma herself, Shinobu is content knowing her allies succeeded in bringing him down.

4 Kanao and Inosuke vs. Doma

Kanao witnesses Doma killing Shinobu, filled with rage, she wastes no time in attacking him. Their battle is a pivotal moment of growth for Kanao, who has evolved from a quiet girl unable to express her emotions into a determined fighter, ready to avenge her sisters. During the battle, Doma acknowledges that Kanao may be stronger than Shinobu, highlighting how capable she is, which is something fans haven't fully seen yet.

The battle against Doma becomes even more meaningful when Inosuke arrives, as Doma also killed his mother in the past. Kanao and Inosuke showcase their abilities in this fight, but they also prove their duty in ensuring Shinobu's sacrifice wasn’t in vain. Together, the two avenge their loved ones and ensure Doma's reign of terror finally ends.

3 Tanjiro and Giyu vs. Akaza

A highly anticipated moment in the arc is Tanjiro and Giyu fighting Upper Moon Three, Akaza. This fight is packed with emotional weight, as Akaza was the one responsible for killing the Flame Hashira, Rengoku, in the Mugen Train arc. For Tanjiro, this fight is also a chance to get justice for Rengoku. The bond between Tanjiro and Giyu is also on full display, as this fight will highlight how far they’ve come as both demon slayers and as teammates.

Akaza’s backstory is also revealed, and it offers fans a glimpse into his tragic past and the circumstances that shaped him into who he is. His past adds complexity to his character and makes the fight a collision of ideologies and motivations. This fight is one of the most hype moments fans can look forward to in the movie trilogy due to its combination of deep emotion and action-packed combat.

2 Gyomei, Muichiro, Genya, and Sanemi vs. Kokushibo

One of the most hype moments in the Infinity Castle arc is the battle against Upper Moon One, Kokushibo. He is the second-strongest demon right after Muzan, making him a formidable opponent. The battle against Kokushibo showcases just how powerful he is, as it takes the combined strength of four demon slayers, including three Hashira Gyomei, Sanemi, Muichiro, and Genya, to go head-to-head with him.

Fans will also learn about Kokushibo's past as a former demon slayer who turned into a demon out of wanting immortality and power. This fight is not only a physical challenge but also a symbolic clash, as the demon slayers must face someone who once stood on their side.

1 Zenitsu's New Technique and Fight with Kaigaku

Throughout the series, Zenitsu is known for being a coward, only able to fight effectively when he's asleep. However, in this arc, that all changes. After learning that his grandfather, Jigoro Kuwajima, who was the previous Thunder Hashira, took his own life because Kaigaku became a demon, Zenitsu's whole persona drastically changes. Though the two are not blood-related, Kaigaku and Zenitsu were both disciples of Zenitsu’s grandfather, which makes the conflict even more personal for Zenitsu. Zenitsu meets Kaigaku in the Infinity Castle and is angry and disgusted at seeing his former senior becoming a demon.

Although they never got along, Zenitsu still respected Kaigaku as his senior because of his dedication to mastering the Thunder Breathing style. Kaigaku had learned all the techniques except the first, while Zenitsu had only mastered the first form. The two clash, but it is Zenitsu who lands the final blow and beheads Kaigaku with his newly created Thunder Breathing, Seventh Form: Flaming Thunder God technique. This marks a significant moment of growth in Zenitsu's character development in Demon Slayer, something fans have waited a long time to see.

Demon Slayer: Kimetsu no Yaiba follows Tanjiro Kamado, a young boy who becomes a demon slayer after his family is slaughtered and his sister Nezuko is turned into a demon. Tanjiro embarks on a perilous journey to find a cure for his sister and avenge his family, facing numerous demons and formidable opponents along the way. Set in Taisho-era Japan, the series combines intense combat sequences with intricate character development.
