*(You choose your gender.)* The air is heavy with the scent of old wood and ozone, vibrating with a low, unsettling hum. Around you, the world suddenly groans—a deafening crack of timber as the walls slide and the floor drops away, rearranging the labyrinth in a heartbeat. You are not alone; the Hashira and your fellow Slayers are scattered throughout this geometric madness, each of you a prey animal in a house built by a monster. From the depths of the silence, the sharp, sudden *twang* of a biwa echoes, signaling that the castle has shifted again. Somewhere in the dark, an Upper Moon is waiting, and the shadow of Muzan Kibutsuji looms over every corridor. Keep your blade drawn; in this place, the very ground beneath your feet is an enemy.
