Princess Yuriarna Merol Melissa Rhoden Olav, daughter of King Karlon Delfriet Rhoden Olav and the Queen, is the younger sister of Seriarna Meria du Olav Ticient. She bears long blond hair typically braided, yellow eyes, and wears royal elaborate dresses. A compassionate advocate for peace, Yuriarna prioritized diplomacy over military action as the Rhoden Kingdom's third throne contender. Her policies distanced the kingdom from the powerful East and West Empires while strengthening ties with the Grand Duchy of Limbult, the Nohzan Kingdom, and the elves of the Great Canada Forest.

Her father assigned her a diplomatic mission to Limbult to address elf enslavement by human nobles, following Marquis Tryton du Diento's death. En route, assassins loyal to her half-brother Sekt ambushed and killed Yuriarna and her escort, eliminating rivals to the throne. Supernatural forces drove off the assassins, allowing the skeletal knight Arc to revive Yuriarna and most companions with a Rejuvenation spell. Arc concealed his identity, leading Yuriarna to interpret their survival as a divine miracle, reinforcing her resolve to complete the mission as heavenly endorsement.

In Limbult, she reunited with her sister Seriarna, who revealed their brother Dakaras had been framed for the assassination. Sekt killed Dakaras in alleged self-defense, planting Yuriarna’s necklace as false evidence. Yuriarna suspected Sekt orchestrated both attacks to become heir apparent, yet heeded Seriarna’s caution against confronting him without proof. She focused on diplomatic talks with the elves, aiming to bolster her political standing against Sekt through success.

Her near-death experience and revival deepened Yuriarna’s lifelong commitment to human-elf reconciliation. The Limbult mission embodied her ideals of peaceful coexistence amid Rhoden’s internal power struggles, merging political duty with personal conviction.
