It all could still have been a lie, even if he seemed very sincere, it could be a lie. Maron had been told the full story of demons and how very tricky they were when she was recruited. She had been terribly surprised to meet the little angle Fin and even more surprised to find out that she as the reincarnation of Joan of Arc had to transform into a magical thief to save people's lives and protect God. The stories Fin had told her of demons and how evil they could be, had by this time been backed up by personal experience with them. She had seen gentle fathers turn into heartless monsters who hit their children, a shy nice boy turn into a wolf, and even been tempted into giving up herself by their cruel words. Everything he had just said could have been a lie, just another trick into getting close to her!

"You had better be telling the truth. I won't allow you to hurt anyone here!"

Even if she had no powers and couldn't at this moment seal a demon... There had to be a way to stop him if he was actually evil! She would definitely be keeping an eye on him, that much she could do.
