Faust is a soft-spoken sinner with a sharp tongue. She claims to be highly intelligent and appears to have the accomplishments to back up this self-proclamation- such as having developed Mephistopheles- but nonetheless comes off a bit arrogant because of this. She expresses unwavering faith in her abilities and does not show any signs of panic even in troublesome situations.

She usually speaks in third person.

Her E.G.O, Telepole, makes her to act like a wolf, or more likely a dog.
