"Hmm, I hadn't expected you to be shallow enough to notice physical changes." There was a hint of defensiveness in her tone rather than her usual sarcastic teasing. Even if he wasn't judging right now she was still...strangely worried about a future judgement coming. How odd. The only time she ever cared about someone seeing her demonic features had been when they were someone she actually cared about an opinion of. Irritating.

"In my world dark magic taints you and dark magic is offensive magic," she replied a bit curtly. "Sometimes your features change when you use it. This form was the form I took without a soul, when pieces were taken bit by bit. They show up sometimes when I use a lot of black magic all at once. Is that a problem?" She tilted her head slightly and then looked forward towards the trail they were following.

"Onwards then!" She tried to give a bit of enthusiasm to her statement to take away from any potential emotions besides that he might pick up. "I could clean it up for you." But would she? Probably not now.
