The Demon Slayer Infinity Castle Arc: What Is It?
The demon slayer infinity castle arc picks up right after the Swordsmith Village storyline concludes. Muzan Kibutsuji finally makes his boldest move yet, pulling every major character into a nightmarish dimension controlled by Nakime, the terrifying Biwa Demon.
Inside the demon slayer infinity castle, gravity shifts without any warning. Rooms rotate on invisible axes, staircases flip upside down, and hallways stretch into impossible geometry that defies all logic.
It is a living fortress designed specifically to separate the Hashira and kill them one by one in isolated chambers.
This arc adapts chapters 137 through 183 of Koyoharu Gotouge’s manga. That makes the demon slayer infinity castle the longest single continuous battle sequence in the entire Demon Slayer series by a wide margin.
