Loretta Oratorio is a thief and crest sorceress traveling with Mirabelle, a Crimson Noble, and Jerusha, a Popepi Pipepo. The trio specializes in treasure hunting and stealing from wealthy targets. Loretta strategically leverages her physical appearance, often using her beauty to distract victims before thefts. She casts spells through magical cards called crests, though her effectiveness as a sorceress is hampered by her preoccupation with their monetary value.

Loretta adheres to a strict personal moral code governing crest acquisition and usage, reacting with visible outrage to violations. Despite her opportunistic theft, she occasionally upholds ethical boundaries in specific magical contexts. Her treasure hunts frequently intersect with Sheyenne Rainstorm and his companions, encounters that typically cost her potential gains. This recurring misfortune leads Loretta and Mirabelle to label Sheyenne the "God of Poverty" and actively evade him.

Her methods involve elaborate deceptions, such as posing as a long-lost heiress or infiltrating all-female robbery gangs to access valuables. She maintains a contentious relationship with Sheyenne, resulting in clashes during their encounters. Loretta has black hair cut to neck length, blue eyes, a mole, and frequently wears lipstick. No significant long-term character development or background story beyond her established role as a thief and sorceress is detailed in the available information.
