After losing her family to a Yoma attack, Priscilla made the decision to battle all she deemed evil in the world. Upon joining the Organization, she swiftly ascended to rank #2, and it was rumored that she still possessed untapped powers, potentially more than any other Claymore before her. Similar to Teresa, Priscilla had the capability to fight with immense strength even without utilizing her Youki, rendering her a formidable adversary for anyone dependent on sensing the flow of Youki.
Priscilla was among the four Claymores dispatched to execute Teresa when she defied the organization's rules. However, during their confrontation, Priscilla ended up awakening and killed Teresa while she was off guard. She became one of the most terrifying Awakened Beings ever known.
