Jeanne serves as crown princess and military commander of the Gran Chaos Empire, standing in stark contrast to her idealistic older sister, Empress Maria Euphoria. Where Maria sees grand possibilities, Jeanne thinks in pragmatic terms—her worldview aligns much closer to Kazuya Souma's grounded approach to problems. She's sharp enough to hold her own in negotiations with Hakuya Kwonmin, Friedonia's Prime Minister, which speaks to her political acumen.
Fans often note her best feature is her dry sense of humor, particularly her relentless complaints about Maria. She and Hakuya have become unlikely friends, bonding over their shared frustration with their respective rulers through private Jewel Voice Broadcast sessions. By Maria's own admission, these venting sessions have actually done wonders for Jeanne's mood—she's noticeably livelier and more relaxed since they started.
