Dark Lighting: There is no natural light or windows to the outside world. The space is completely enclosed and dramatically illuminated by thousands of floating paper lamps and lanterns, which project deep shadows and give a golden and reddish tone to the scene. The Impossible Spatial Structure: Endless Labyrinth: The space expands infinitely in all directions. It is composed of an absurd number of overlapping rooms, long empty halls, suspended inner courtyards, and inverted towers. Distorted Gravity: Gravity inside works individually for each platform or wall. A hunter might be standing on the ground while a demon watches him upside down, stepping on the ceiling, or perpendicularly on a side wall as if it were the ordinary floor.

They connect to doors that lead to the void or to new floating rooms. The Living Mechanism and the Central Room Real-Time Mutation: The castle is not static. When the oni Nakime plays the strings of her Biwa instrument, the sound echoes and the entire structure moves instantly.

Muzan's Throne: At the heart of this dimension is an origin point where Muzan Kibutsuji used to give orders.

In the final stage, this area expands, revealing a structure.
