Vylaine is the only survivor of the Kiringu Supuri. Her family was kidnapped by Satsujin, the one who caused the attack. Vylaine was infected by a chemical, causing her to grow wolf ears, a cat tail, fox fangs and panther claws. She hides these mutations, training herself with her training partner, Momarue, a previous friend of Satsujin. Searching for her family, she has to defend towns and people from Shadows. As time goes on, Vylaine wonders if she'll ever see her family again.
