プリシラ・ウルサイス

Priscilla is a student at Rewolf Black Institute and the younger sister of Irene. She and her sister are from a war-torn country, and got saved by the student council president of Rewolf Black Institute, Dirk Eberwein, as an exchange for Irene becoming Gravisheath's owner. Priscilla is kind hearted and watchful over her sister and even those she has just met.

Priscilla is a rare regenerative type Strega that is able to heal herself over time by regenerating anything lost. While she can regenerate, if something like her blood is taken in large quantities over a short period of time, she can still die.
