Mina is a withdrawn and introverted woman. She distrusts people, unsure of how to act around others without being suspicious of them, due to being simultaneously revered and reviled for her powers. She has little regard for her own welfare especially after absorbing the evil energy in Chample, conceding to be doomed to live a short life.

As an exorcist by profession, she is wary of objects and people with unusual powers, sometimes branding them as evil despite not necessarily being so.
