Although raised as a princess in Orb and taught to be proper, sophisticated, and elegant; Cagalli is far from it, for she is quite stubborn, rebellious, masculine, and often free-spirited. Cagalli is also shown to dislike being called a princess and when someone calls her one she instantly tells them not to call her that again. Despite rebelling against both her father and her responsibilities as a princess, she is quite loyal to her country and more than willing to give up her life to save it. In Destiny, Cagalli becomes the leader of her country in place of her father. However, she is shown to be reluctant in speaking against the pro-Alliance leaders of Orb and had trouble difficulty in handling situations when it involves her country's future. Eventually, she discovers that she is a capable leader and both her people and herself regained their trust in her.

As Chief Representative of Orb, Cagalli is shown to be a competent diplomat with considerable knowledge in foreign policy.
