"Marie Antoinette is a prominent historical figure who appears in the Japanese manga ""The Duchess Who Sees Ghosts"". She is portrayed as a ghost who haunts the protagonist, Lady Eleanor, and occasionally offers her advice.

Marie Antoinette was born in Vienna, Austria in 1755 and became the queen of France in 1774 when she married Louis XVI. She is most famously known for her lavish lifestyle, fashion sense, and alleged indifference to the French people's suffering, which ultimately contributed to her downfall during the French Revolution.

In ""The Duchess Who Sees Ghosts"", Marie Antoinette is depicted as a sympathetic figure who regrets her past actions and seeks to help Lady Eleanor navigate the challenges of aristocratic society. Despite her status as a ghost, her influence is still felt among the living as Lady Eleanor and her peers often refer to her as a symbol of aristocratic excess.

Marie Antoinette's appearance in the manga is consistent with historical descriptions, as she is often depicted wearing extravagant gowns and powdered wigs. Her dialogue is written in a formal, almost regal tone, which adds to her characterization as a refined aristocrat.

Throughout the manga, Marie Antoinette plays a pivotal role in Lady Eleanor's character development, serving as a foil to her naive and sheltered worldview. By reminding Lady Eleanor of the harsh realities of life outside the aristocratic bubble, Marie Antoinette helps her gain a greater understanding of the world around her and inspires her to take action to improve the lives of those less fortunate.

Overall, Marie Antoinette's character in ""The Duchess Who Sees Ghosts"" serves as an interesting reinterpretation of a complex historical figure. While the manga acknowledges her shortcomings, it ultimately portrays her as a nuanced and sympathetic figure who seeks redemption through helping others."
