What is the Infinity Castle?
The Infinity Castle is Muzan Kibutsuji’s eerie and seemingly endless fortress. Unlike any traditional stronghold, it is a surreal labyrinth of shifting corridors, floating platforms, and gravity-defying architecture. Its design disorients intruders and creates a battlefield where demons hold the advantage.
Who Controls the Infinity Castle?
Nakime controls the Infinity Castle, using her Blood Demon Art to manipulate its structure and summon demons within its extra-dimensional space. She is a powerful member of the Twelve Kizuki, holding the rank of Upper Rank Four, and her abilities allow her to create and rearrange the castle’s layout at will using her biwa.
Who Created the Infinity Castle?
The Infinity Castle in Demon Slayer was created by the Biwa Demon, Nakime, using her Blood Demon Art. This art allows her to manipulate the alternate dimensional space that serves as Muzan Kibutsuji’s lair, enabling her to rearrange the castle’s architecture, teleport beings within it, and even project objects to battle opponents.
How Big is the Infinity Castle?
The Infinity Castle is a pocket dimension and parallel universe that is essentially infinite in size, with its layout and rooms constantly shifting and rearranged by Nakime’s Blood Demon Art. While not infinite in the traditional sense of an unending space, its structure is so vast and complex that it appears to have no physical end, functioning more like a warped, never-ending maze that can hold an unknown number of demons.
