The character referred to as Orelia is identified in Unnamed Memory Act.2 as Aurelia, also listed with the full name Aurelia Canao Naysha Faurecia. She is a supporting figure in the second season, connected to the royal family of the kingdom of Gandona. Her background places her as a member of that royal house, and she appears in the story when she attends the ceremony held to celebrate Oscar's birthday. On that occasion, she serves as the representative of the King of Gandona, which indicates that she holds a position of formal standing within her kingdom's court.

Aurelia is accompanied by Travis, a gifted magic user who acts as her guardian. Their relationship defines her role in the plot, because Travis draws danger toward her. The demon Phaedra is obsessed with Travis and, as a way of reaching him, targets Aurelia. To protect her, Travis asks Tinasha to act as a substitute, drawing Phaedra's assault away from Aurelia. Aurelia thus becomes a point of vulnerability in a conflict between a demon and the people protecting the protagonists. While Tinasha faces Phaedra elsewhere, a mysterious infant wrapped in black mist appears before Oscar and Aurelia in Farsas castle, placing Aurelia at the edge of the strange events unfolding around the royal household.

The anime does not explore Aurelia's personality, private motivations, or personal development in depth. She appears mainly as a royal figure whose safety matters to those around her and whose connection to Travis places her within a supernatural threat. No particular combat or magical abilities are described for her; her significance lies in her status as a protected royal rather than in active participation in battles. Her key relationships are with Travis, her guardian, with Oscar and Tinasha as the hosts who shelter her during her visit, and with Phaedra as the antagonist who seeks to harm her. Her role in the story is therefore shaped by the danger she attracts and by the protective actions others take on her behalf.
