Female Devil (She has a numbered name, but they didn't put it out there in the first 10 chapters and there's no wiki out there yet that helped me find her name *cries*) is seductive and beautiful, and she holds her beauty as a weapon in her line of contract work.

Voice Type: Medium-low / Low. Go for a charming and sultry voice for her, though she won't be purposely putting on the charms all the time.
