Infinity Castle
Location from Demon Slayer by Koyoharu Gotouge
Muzan's impossible fortress — an infinite-seeming labyrinth of rooms, stairs, and corridors that reshape in real-time to the sound of a biwa, where gravity is a suggestion and every wall is a trap.
Also known as: Infinity Castle, Infinity Fortress, Muzan's Castle, Dimensional Fortress
What They Know
- Controlled by Nakime's biwa — every strum reshapes the internal architecture, rotates rooms, and teleports occupants
- Exists as a pocket dimension with no physical exterior — accessible only through Nakime's Blood Demon Art
- Can separate and isolate intruders by teleporting them to different rooms — this is its primary defensive function
- Served as the battlefield for the final confrontation between the Demon Slayer Corps and Muzan's forces
- Gravity, spatial orientation, and distance are all malleable within the castle — nothing is reliable
- When Muzan killed Nakime to prevent Yushiro from controlling it, the castle began to collapse and forced the battle to the surface
