Description
Roroa Amidonia, daughter of militaristic ruler Gaius Amidonia and younger sister of Julius Amidonia, is the princess of the former Principality of Amidonia. Her petite, slender frame stands less than 160 cm tall, featuring an attractive round face, small beady eyes, and braided twin tails depicted as chestnut in light novel/anime adaptations but black in manga illustrations.

Her personality blends sharp business acumen with a cheerful, informal manner, often using merchant slang. Despite her royal status, she focused solely on economic pursuits, clashing severely with her father Gaius. He consistently diverted funds she secured for civilian welfare and infrastructure towards arms development instead. Working covertly with former Finance Minister Gatsby Colbert, Roroa implemented financial measures that prevented Amidonia's complete economic collapse despite resource shortages and food insecurity resulting from earlier territorial losses to the neighboring Elfrieden Kingdom.

During the One Week War, Roroa severed ties with her family after Amidonia's defeat and her father's death, hiding with Colbert. She later orchestrated non-violent revolts against her brother Julius's ineffective rule, exploiting civil unrest triggered by his attempts to erase Elfrieden's reforms. Recognizing improved living standards under Elfrieden's occupation and anticipating further invasions, she devised a political solution: presenting herself as a bride to Elfrieden's King Kazuya Souma to legitimize his annexation of Amidonia. Her grandfather, General Herman Neumann, delivered her hidden inside a carpet to Souma to make this strategic marriage proposal.

As Souma's third primary queen consort in the newly formed United Kingdom of Friedonia, Roroa applied her economic expertise. She pioneered advertising commercials for the kingdom's Jewel Voice Broadcast system, generating substantial revenue. She established a private company under her acquaintance Sebastian Silverdeer, expanding the "Silver Deer" brand from clothing into broader commercial ventures. She stipulated that any children she bore with Souma would inherit her business enterprises, not royal succession claims.

Later developments include reconciling with her exiled brother Julius during Souma's diplomatic mission to the Union of Eastern Nations, forming a bond with Julius's wife Tia Lastania. During this period, she advocated for granting asylum to the Lastanian royal family. She eventually married Souma officially during his coronation, agreeing to co-parent all royal children collectively. Her company later facilitated the covert evacuation of Lunarian refugees during upheaval in the Orthodox Papal State. Personal milestones include her pregnancy coinciding with Tia's and lighthearted remarks about childbirth preparations.
