Olivia, former joint ruler of the Grand Duchy of Magnal and known as the Valiant Duke, was famous alongside her brother Roland for her prodigious talent with the sword since childhood. Even among the illustrious sword-wielding Magnal family, her talent stood out. She defeated opponents effortlessly, whether they were strong or weak. Her strength had reached the level of a phenomenon, and her people never thought of her as merely strong—she was a force of nature. When the Rift Crisis occurred in Noctis Nebula, Olivia chose to stand against it. She fought against countless Rift aberrations for days on end, and when the battle finally ended, no one remained near her—not enemy nor ally. She set out again in search of enemies, not out of vengeance, but because she saw it as the duty of a ruler to bring an end to the war. After a fight that took her into the Rift, she found herself on Earth. Realizing the battle was over, she began to live in seclusion on the outskirts of the city, seeking to figure out what her purpose should be now that her duty as a ruler had ended.
