Kayla is the younger sister of Tanya, Kelly's, Luke's and Rio's friend, as well as Amur's, Lou's and Sadie's auntie/only relative left alive. She is under Kaitlin's command and she had romantic feelings towards Snape. Kayla was there when her sister was murdered, making her furious towards all wolves, even Fang, who was only half wolf. Yukimura however taught her not to hate wolves just because an evil one killed Tanya. She learnt from her mistakes and never threatened anybody else ever again.
