Constance speaks in a domineering, haughty tone, but maintains a scope of politeness and refined speech, being a noble before hiding in Abyss. At times, she can be rude, especially when loudly voicing her aspirations to restore House Nuvelle to its former glory. Interestingly, Constance also seems to need praise to feel better about herself, as in her victory quotes she demands recognition.
