all the shadow birds of the world

Autumn had indeed had a treaty with several dark birds long ago. But when it came to safety, she would kill all the shadow birds she liked. With a snarl, Autumn Berry leapt fiercely onto several. She killed quickly. It only took her about eight seconds to kill one, but could vary according to their strength. But it seemed as if they just kept appearing from nowhere! Her white fangs flashed as she cracked crow spines that she could grab a hold of, but it seemed as if the flow of guards would never end.
