The first Demon Slayer: Infinity Castle film showcases three major battles that are central to the story and have left fans on the edge of their seats. One of the standout fights is Shinobu Kocho taking on Doma, the deadly Upper Rank Two demon, in a clash that combines strategy, agility, and sheer determination. Another highlight is the high-stakes battle between Tanjiro Kamado and Giyu Tomioka against Akaza, Upper Rank Three, which delivers breathtaking swordplay, emotional intensity, and peak animation. Finally, Zenitsu Agatsuma faces off against Kaigaku, the newly appointed Upper Rank Six, in a dramatic showdown that tests Zenitsu's courage and mastery.
Yes, Akaza is dead. The major turning point in the film is the fall of Upper Rank Three, Akaza, one of the most feared members of the Kizuki and infamous for having killed the Flame Hashira, Kyojuro Rengoku. His battle against Tanjiro Kamado and Giyu Tomioka is a fierce test of endurance, skill, and raw power, showcasing not only Akaza's incredible combat abilities but also the unwavering determination of the Demon Slayers. In a shocking display of resilience, Akaza continues to fight even after being decapitated, driven solely by his indomitable will. However, the tide turns when Akaza is confronted by long-buried memories of his human life. Guilt, regret, and sorrow slowly erode his fighting spirit, forcing him to confront the choices he has made as a demon. Unlike many other antagonists, Akaza's death is profoundly emotional, rather than being struck down by a Demon Slayer's blade, he ultimately chooses to end his own life, seeking redemption and the chance to reunite with the loved ones he lost.

Kaigaku, the newest member of the Twelve Kizuki and former senior disciple of Zenitsu, faces off against his old comrade in a one-on-one battle fueled by betrayal. The fight ends with Zenitsu defeating Kaigaku using his newly created Seventh Form: Honoikazuchi no Kami.
Meanwhile, Insect Hashira Shinobu Kocho confronts Upper Rank Two demon Doma, whose polite facade hides a history of atrocities. Using her poison-coated Nichirin blade and Insect Breathing techniques, Shinobu fights to avenge her sister Kanae, but Doma's adaptability overwhelms her, ultimately leading to her death.

As Akaza fought, memories of his past as a human named Hakuji resurfaced. He had once stolen medicine for his sick father, who later took his own life to avoid being a burden. Hakuji then lived with Keizo, a dojo owner, and cared for his sick daughter, Koyuki, finding happiness and even being promised the dojo and Koyuki's hand in marriage.
Tragedy struck when a rival dojo poisoned Keizo's well, killing him and Koyuki. Devastated, Hakuji killed everyone in the rival dojo, and with nothing left to live for, he accepted Muzan's offer to become a demon.
Demon Slayer: Infinity Castle Part 1 concludes at a dramatic and pivotal moment in the story. Following the shocking death of Insect Hashira Shinobu Kocho, her adoptive sister Kanao Tsuyuri prepares to step into the fray against the formidable Upper Rank Two demon, Doma, who has yet to fully grasp the consequences of his actions. The film's ending sets the stage for an emotionally charged continuation, promising a battle that is not only a clash of strength and skill but also one driven by personal grief, vengeance, and the weight of loss. Fans can expect the next installment of the Infinity Castle arc to explore these themes deeply, heightening the stakes for the Demon Slayer Corps and delivering a continuation that is both intense and heartbreaking.
