Roanna Fontaine, eldest daughter of Duke Fontaine, belongs to a noble house renowned in Beltrum Kingdom for pioneering magic research and inheriting potent magical aptitude. Her childhood intertwined with Princesses Christina and Flora Beltrum, though courtly decorum enforced restraint, tempering their camaraderie with formal deference. The Fontaine family’s influence wanes under political strife, key members confined by adversaries like Duke Arbor’s faction, leaving Roanna’s standing in the fragile Restoration movement dependent on dwindling resources and her lineage’s fading prestige. Her striking appearance mirrors noble refinement: cascading honey-blonde curls arranged in meticulous ringlets—playfully dubbed “drill hair”—frame piercing emerald eyes, while her poised figure exudes disciplined elegance. A solemn bearing and rigid posture reinforce her guarded demeanor, her sternness toward lower-born individuals arising not from cruelty but a rigid adherence to aristocratic duty. At Beltrum Royal Academy, Roanna secured consistent academic excellence, trailing only Christina and Rio in rankings. As class representative, she initially scorned Rio’s illiteracy, her pride wounded when he rivaled Christina’s prowess. Though she publicly defended him against nobles like Alphonse Rodan, accusing him of cheating, their rapport remained cool, strained by Christina’s dominance and Roanna’s unyielding self-importance. Exiled to Galarc after Beltrum’s collapse, she aligned with Flora and the Huguenot faction, ascending as Hiroaki’s attendant and betrothed. Tasked with curating his charismatic image, she tempered his recklessness—dissuading futile duels with Rio or rash confrontations—while skillfully mediating his political dealings. Their alliance deepened into playful mutual flirtation, though his unpredictability tested her pragmatic resolve. Post-academy interactions with Rio remained diplomatically reserved. She acknowledged his heroism toward Flora and privately lamented Beltrum’s blunder in ostracizing him, yet rebuffed proposals to wed him, steadfastly dedicating herself to Hiroaki and the Restoration’s cause. The web novel highlights her diplomatic acuity, securing alliances like the Rikka Firm’s aid through shrewd negotiations. The light novel underscores her precarious position: familial survival hinges on her choices, her political isolation mitigated solely by her title’s lingering authority. Amidst these trials, she treads a delicate balance—upholding familial honor, navigating court intrigues, and shielding Hiroaki’s reputation—all while concealing the weight of her unraveling legacy.
