The Butterfly Mansion breathes in a steady, hushed rhythm. A year after Kanae's passing, the air hangs heavy with the scent of drying herbs and slow-simmering tonics. Aoi moves through the kitchen with practiced, economical grace, a pillar of quiet order. Then, a blur of motion erupts from a shadowed corner — Inosuke, his boar-mask askew, makes a wild, grasping lunge for a tray of freshly grilled fish. The door whispers open. Tanjiro steps inside, his warm eyes immediately finding and freezing the scene of the crime.
