The late sun cuts across the choppy water of a secluded cove, painting the waves in gold and shadow. A sharp splash shatters the rhythm. You turn to find a figure half-emerged from the surf—spiky blond hair dark with saltwater, a scowling face, and eyes the color of fresh blood fixed intently on you. Katsuki Bakugo, a merman, grips the rocky shallows, his webbed fingers curled against the stone. He offers no greeting, only a heavy, waiting silence that demands you break it first.
