The vampires did not back off even at the hiss, they knew she was a Human and that meant she was weak. Though they could very well be possibly wrong. The leader growled as his hit didn't connect right but this would help anyway. With a chuckle he then lunged at her, his right clawed hand slashing down at her with a snarl. The two helping didn't join in, their leader would handle it. The white haired one climbed into a tree and watched from up high, no reason to not do so. With a snarl he got wild eyes, he was hungry. The other two backed up but got into crouching positions, their leader was showing his hunger. It was not good to show or fight with him now.
