Infinity Castle – The Beginning of the End for Demon Slayer
What is the Infinity Castle Arc?
Demon Slayer: Infinity Castle adapts the beginning of the series’ climactic final arc, taking Tanjiro Kamado and the Demon Slayer Corps into a twisted, ever-shifting labyrinth controlled by Muzan Kibutsuji. After years of battling Lower and Upper Moon demons, Tanjiro and the remaining Hashira finally launch an all-out assault on Muzan’s stronghold. But the Infinity Castle is no ordinary battlefield—it’s a nightmarish realm designed to separate, confuse, and annihilate its intruders.
This arc promises heart-wrenching moments, high-stakes duels, and shocking revelations that will set the stage for the ultimate showdown.
Where the Story Left Off
The last instalment of Demon Slayer, The Hashira Training Arc, saw Tanjiro and his allies undergoing grueling preparation for the inevitable war against Muzan. Now, with the Demon King himself appearing at the Demon Slayer headquarters, the Corps is thrown into battle sooner than expected, leading to their unexpected descent into the Infinity Castle.
The upcoming film will pick up right where the anime left off—plunging viewers straight into the chaos of the final battle.
