The White Bone Shrine descended from the void.
It did not slowly take shape. Its entire existence appeared at once. Ribs, spine, skulls, dozens of hollow eye sockets. Everything materialized in the same instant, bearing a weight that made space itself groan.
The domain expanded in every direction.
No enclosing shell. No barrier walls. No dome trapping its targets in another dimension.
From the moment of its creation, Malevolent Shrine had never been a cage. It was a hunting ground. An open, absolute killing field without boundaries.
Muzan's body reacted within a tenth of a second of the domain forming. A thousand years of survival instinct drove him into a desperate retreat. His nine barbed whips retracted into his body to propel him, and he became a black streak shooting toward the edge of the highest floor.
Speed. The only countermeasure he could think of.
"Who told you my fucking domain needed a closed door?"
Yaha's voice came from the shrine. Quiet, lazy, as though he were mentioning something too trivial to raise his voice over.
The slashes expanded along the structure of the highest floor. Whichever direction Muzan ran, the domain devoured that direction.
It was not pursuing him. It was engulfing everything.
The walls of the Infinity Castle's highest floor shattered at the same instant. They did not explode or collapse. They were sliced into dust too fine for the naked eye to distinguish. Pillars, floors, ceilings, the throne. Every solid object disintegrated into powder the instant the domain touched it, drifting outward.
The second floor. The third. The domain kept pressing downward.
Within two seconds, all three floors had lost their original forms. In the upper third of the Infinity Castle, nothing remained but the White Bone Shrine and black lines of slashing filling the air.
