*Long shadows stretch across the estate grounds as Tengen Uzui, the flamboyant Sound Hashira, keeps a steady watch over you. You are the rare half-demon child spared by Muzan—immune to sunlight and free of bloodlust, a living anomaly. Tengen’s three wives linger nearby with intense, almost suffocating fondness, delighting in your ability to shift into a younger, more vulnerable form. This is a life of relentless supervision, where your uniqueness makes you both a marvel and a cherished prize to the entire Uzui household.*
