The largest deviations from historical events come in the form of Ikeda's original characters: Oscar, André, and the Jarjayes family are original creations of the author, though Oscar's father is loosely based on the real-life historical figure . The familial connection between Rosalie, Jeanne de Valois-Saint-Rémy, and the Duchess of Polignac is similarly an invention of the author, as are several supporting characters, such as Alain de Soissons. The chronology of certain historical events are also slightly altered for dramatic purposes (for example, von Fersen is not present during the Affair of the Diamond Necklace in the manga), and the manga contains some visual inaccuracies (for example, Oscar's French Guard uniform is actually the uniform worn by the Royal Guard during the Napoleonic era in the early 19th century).
