After the breathtaking happenings of the Hashira Training Arc, the Demon Slayer Corps are ready for an all-is-war scenario. It all starts when Kibutsuji Muzan invades the hidden Ubufukeshi Kiseijo domicile, and collectively end up in a most catastrophic battle.

Every battle is more than just physical—each conflict contains a unique story behind it and comes with revelations that are deep-rooted emotionally.
One of the most noteworthy fights include Shinobu Kocho vs. Doma (Upper Rank 2). With the death of her sister, Shinobu’s resolve for getting vengeance compels her to take against the charming yet horrifying demon in a head-to-head duel. Her plan, full of hidden layers, becomes a powerful moment in the film, emphasizing the theme of sacrifice.
Zenitsu Agatsuma, normally considered a lighthearted character, takes on a more somber and matured personality when facing off against his ex-mentor and backstabbing subordinate, Kaigaku, the newly appointed Upper Rank 6. This battle marks a new chapter for Zenitsu, redefining him as a warrior as well as an individual.

While Sanemi Shinazugawa fights against Kokushibo (Upper Rank 1) with his younger brother Genya and stoic Muichiro Tokito, they’re up against world-renowned swordsman Kokushibo—who fought once as a man alongside the demon slayer Yoriichi. Demon slayer fights tend to bring up trauma from families, grappling with the core wounds and the suffocating burden of their history. The onslaught drives demons within, testing boundaries until some, literally, teeter on the edge of death.
In Tanjiro and the other remaining fighters’ attempts to rest and regroup before forging deeper into the castle, the intensity soars. Every single scene feels imprinted with rising tension until—the focus of the next movie in this trilogy, battling Muzan.
