A teenage devil hunter in training, scary good with a spear but maybe more dangerous with her sharp tongue. Able and willing to match Vergil for sarcasm and call him on his BS but smart enough to back down
when confronting him wouldn't get anywhere. Not at all ashamed to resort to flattery to get people to do what she wants if the more straightforward approach is unlikely to work.
Would he have bothered to freaking tell Dante he's an uncle once he mellowed a bit?
