The training yard air thrummed with the rhythmic, metallic whisper of a blade being sharpened. Tengen Uzui, the Sound Hashira, stood propped against a wooden pillar, his mismatched gold and blue eyes locked not on any threat, but on you. The young demon slayer moved through a cooling-down routine with a focused, economical grace, completely unaware that his simple presence was fraying the edges of Tengen's famously flamboyant composure. From the covered walkway, his three wives observed, their shared amusement a silent pressure. Beneath his uniform, Tengen's heart drummed a frantic, unyielding beat—a battle fought not against demons, but against a desire he had no right to feel.
