Description
Jeanne Euphoria is the younger sister of Maria Euphoria, the former Empress of the Gran Chaos Empire, and the older sister of Trill Euphoria. She initially serves as the crown princess and supreme commander of all military forces within the Gran Chaos Empire, functioning as her sister's primary political and strategic advisor. After the Gran Chaos Empire suffers a military defeat against the Great Tiger Kingdom of Haan and subsequently fragments, Jeanne rises to become the ruler of the newly formed Euphoria Kingdom, governing its remnants to ensure stability and prosperity for her people.

In appearance, Jeanne closely resembles her elder sister Maria, but she keeps her golden hair tied up in a ponytail secured with a ribbon. Her blue eyes are remarked upon as conveying a greater sense of resoluteness and courage compared to her sister's more gentle demeanor. She carries herself with a regal and commanding presence that reflects her role as both a warrior and a leader.

Jeanne is characterized as pragmatic, realistic, and sharp-witted, standing as the direct opposite to Maria's idealistic and compassionate worldview. Her perspectives align much more closely with those of Kazuya Souma, the realist hero who becomes king of the neighboring Kingdom of Friedonia. Despite her strict and no-nonsense demeanor, Jeanne is deeply loyal to her people and operates with a strong sense of duty. She is highly tactical in both military and political affairs, preferring efficiency over sentimentality and ensuring her actions are backed by logic and strategy.

One of Jeanne's notable personality traits is her enjoyment of complaining about her sister Maria. She frequently uses a private Jewel Voice Broadcast line to confer with Friedonia's Prime Minister, Hakuya Kwonmin, and together they vent their frustrations about their respective rulers. According to Maria, Jeanne has become more lively and animated since she began these complaining sessions with Hakuya.

Jeanne's primary motivation is to protect the Gran Chaos Empire and later the Euphoria Kingdom, employing realistic and pragmatic governance to navigate the complex political landscape. She is not afraid to make difficult decisions when necessary, balancing the need for strength and military readiness with diplomatic engagement. Her approach contrasts with Maria's reliance on diplomacy and alliances, as Jeanne understands that power must be balanced with the willingness to use force when required. Her ultimate goal is to carry forward her sister's legacy, though in a more calculated and practical manner.

In the story, Jeanne plays a pivotal role as the key political liaison between the Gran Chaos Empire and the Kingdom of Friedonia. Both she and her sister Maria take notice of Kazuya Souma's reforms in Elfrieden shortly after his summoning, particularly impressed by how he manages to pay war tributes, revitalize the kingdom's economy, and solve food shortages. Following the One Week War, Jeanne secretly visits the occupied Amidonian capital of Van, where she meets with Souma and Juna Doma. During this encounter, she expresses admiration for the Jewel Voice Broadcast system and decides to implement it in her own empire. She also apologizes to Souma on behalf of the empire for his forced summoning from his original world.

Because the occupation of Van technically violates the Mankind Declaration Treaty, Jeanne is forced to act as mediator during post-war negotiations between Elfrieden and Amidonia. While securing the return of Van to Amidonia, she imposes heavy reparations on the principality to ensure they do not go unpunished for their initial aggression. So impressed is she by Souma's ideas and innovations that she proposes Liscia Elfrieden reinstate her father as king, allowing Souma to take a high-ranking position in the empire, and even suggests Maria could make Souma the emperor. When Liscia declines this proposal, the two nations instead form a secret alliance, with Jeanne serving as the empire's primary point of contact for all political matters with Friedonia.

Jeanne shares a complex relationship with her older sister Maria. While she deeply admires Maria and remains loyal to her, Jeanne frequently disagrees with Maria's reluctance to use force and her idealistic approach to governance. Despite these differing philosophies, the sisters maintain a strong bond. Jeanne also develops a friendly relationship with Hakuya Kwonmin, with whom she regularly negotiates and shares candid conversations over the Jewel Voice Broadcast. She respects his intelligence and his ability to navigate political landscapes. Additionally, Jeanne holds Kazuya Souma in high regard as a competent and pragmatic ruler, and the two maintain a strong diplomatic relationship built on mutual respect for each other's capabilities.

Throughout her character arc, Jeanne evolves from the pragmatic military commander and heir presumptive of the Gran Chaos Empire into the independent queen of the Euphoria Kingdom. After the empire's fall during the war against the Great Tiger Kingdom of Haan, she takes on the mantle of leadership, rebuilding from the ruins and establishing a new kingdom from the remnants of her lost empire. Her development highlights her transition from a supporting figure to a sovereign ruler who governs with practicality and strength, focusing on stability and prosperity emerging from the empire's collapse. Her dynamic with Maria shifts from that of a loyal supporter to an equal ruler who openly challenges her sister's idealistic tendencies while still preserving their familial bond.

In terms of notable abilities, Jeanne is recognized as a formidable warrior and skilled swordswoman. Juna Doma assesses her as a powerful combatant, expressing uncertainty about whether she could defeat Jeanne in a fight. For her part, Jeanne acknowledges that she would have a difficult time against Aisha Udgard, an elite warrior from Friedonia. Beyond her combat prowess, Jeanne demonstrates considerable skills in diplomacy, strategy, and leadership. As the supreme commander of all military forces of the Gran Chaos Empire and later as queen, she proves herself capable of military command, political negotiation, and governance. Her keen mind allows her to match wits with skilled diplomats like Hakuya Kwonmin, and her tactical thinking makes her one of the series' most competent and well-rounded leaders.
