not a sound but a flap of wings

Swans were not an easy prey, certainly when they could take flight at any moment. And though Kuroo was a fisher-wolf at heart, Hattori knew he was capable of leading this hunt, that if they all worked together and played their part just so they would succeed. They had to, if the Oaks were to be their own. Kuroo decided they ought to go for the largest bird, set their standards high and work down if things did not go to plan. Hattori grunted in approval, it seemed like a sound idea to him, one he had no quarrel with.

And thus the group decided what their approach would be. It seemed Usagi would grab one wing, leaving the other for himself.

"Then I shall claim the other."
