At first, Charlotte is seen to be a rather naive and slovenly young girl. She is also honest and will freely speak her mind, but she acts as a proper princess when need be. She has no trouble apologizing for problems she causes.

She has a tendency to cry whenever things don't go her way; according to her maid Alberta, she has a bad habit of forgetting who she is when she gets too emotional.

Charlotte claims that she is a crybaby with a short temper, however, she is actually a strong-willed girl, as seen when she claims that she will go hunting with Damian and will not let him leave her behind. She says that she had the education to be a fine match for any man. She is also self-confident as she tells Damian that she is sure that she'll be a faster ride than him.

Charlotte is a very hardworking, tough, intelligent girl who doesn't stop until she reaches her goals. This is shown where she began studying intensively on all the benefits a marriage between members of the Flugel and Drossel royalty would bring to the Kingdom of Drossel. She also laid the groundwork with her father and the cabinet so the Drossel would more likely choose the Flugel family, which they eventually did. She is very caring and holds those she cherishes close to her heart.
