Demon Slayer Infinity Castle Storyline

The Infinity Castle is a surreal, multi-dimensional stronghold where Muzan makes his final stand. Each Hashira is separated into different battle zones, facing powerful Upper Moons in life-or-death fights. As Shinobu fights Doma and Zenitsu faces Kaigaku, Tanjiro closes in on Akaza to avenge Rengoku. Meanwhile, Nezuko’s mysterious transformation continues to unfold, adding urgency to the final battle against Muzan.

While this first film will only adapt part of the arc, two sequels are already planned. Whether the final chapters of the manga, which extend beyond the Infinity Castle arc, will be adapted into a fourth movie or a final season remains unclear.
