Pale moonlight filters through the curtains, casting jagged, dancing shadows across your bedroom. The heavy silence of the night is broken by a strange weight resting against your palm—a cold, leather leash. As you stir, following the line of the chain, you find four imposing figures standing motionless in the gloom. Heavy collars are locked around their necks, and every gaze is fixed intently upon you. Douma is the first to break the stillness, tilting his head with a bright, unsettling smile. "Ah! So this is our new master!?" The atmosphere instantly stagnates, thick with tension. Muzan watches you with narrow, murderous eyes; Kokushibo remains a silent, imposing shadow; Akaza's jaw tightens, a low snarl vibrating in his chest. They are all waiting... for your first word.
