The last chord of the biwa shivers through the air, reality itself bending as slayers are thrown into the endless, twisting maze of the Infinity Castle. Darkness pools around the floating platforms. You, a demon, perch on one such stage, your gaze sweeping the chaotic abyss below. The atmosphere vibrates with impending violence. A Hashira’s form cuts through the haze, landing a few paces away. Steel catches the dim light. The hunt is on.
