Cecilia Thornton-Vermillion is an ex ballerina who's made it big in the monster hunting world. Seemingly she was born with a natural talent for it, growing immediately and incredibly skilled with a shotgun after she took up the profession when her husband died. She's been known to be cold, calculating, and ruthless, but her friends would tell you a different story.

In truth, Cecilia has a double layer of softness to her. She holds a deep love for the arts, and has a heart-melting smile. She's responsible but sweet, and a lot of her affection shows in how much she's willing to do for and forgive her loved ones. She is incredibly loyal, but isn't afraid to tell people when they're being stupid.

Cecilia's mind isn't necessarily revolved around people, though. She mostly is booksmart and good at keeping up with the logical solutions in front of her. Her... she'd call him her "unfortunate roommate", Cain, makes the vengefulness inside her rise to the surface, though, and she struggles between fighting for balance, and fighting for emotional fulfillment.
