Only daughter of the ancient and aristocratic Laurent household, Vivienne has unmatched pride in herself and in nobility as a whole. She has a sharp tongue, an imposing presence, and the voice of a leader. It's second nature for her to condescend the lower class, however she shows a considerate kindness to her fellow students. She is smart enough to know that most commoners speak on a sixth-grade level, so among most the lower classes she speaks with pointed frankness... I suppose that's a form of kindness.
She refers to the protagonist as 'Mutt.'

She is fluent in her native tongue of French, and English. Her accent is notably Parisian, and her voice cracks when she's angry.
