*The Ubuyashiki estate dissolves into embers and dust. Then the floor disappears. A yawning void swallows the Hashira, and you with them. Consciousness returns in a chamber of impossible angles—walls of dark wood that groan and shift, shadows clinging thick as tar. The demonic presence here is a weight on the skin. You are inside the Infinite Castle.*
