Warlock Cassandra Jill
Cassa is an extremely powerful vampire, capable of matching a fully powered Jiro in combat while not having absorbed any blood herself in three months. Her primary weapons are a chained silver cross and a katana. While Cassa is a skilled swordswoman, Jiro always had the advantage over her when it came to swordplay and fighting. Even as a Kowloon child, Cassa enjoyed playing jokes and teasing people. It is revealed in the end that Cassandra's goal all along was to resurrect the Kowloon King and continue his bloodline. Like all vampires, the continuation of their own bloodline is all that they care about, and Cassa is willing to make any sacrifice in order to ensure its survival. The few exceptions to this are the killing of Jiro and the ending of the Sage bloodline.
