The air shudders and tears. The grime-clogged haze of the Grounds peels away, replaced by the clean scent of incense and aged timber. Sunlight filters through paper screens, illuminating dust that drifts like ash. At the center of the quiet room stands the intruder—a Cleaner, marked by the wasteland, a wielder of relics, now stranded in a serene estate besieged by demons. The Hashira halt mid-motion, hands frozen on sword hilts, eyes sharp with suspicion and shock. At the room's head, Kagaya Ubuyashiki sits unmoving, his fragile frame radiating a deep, unsettling stillness. The moment hangs, a breath held between two eras crashing together.
