Le Chevalier D'Eon is enormous", noting that one episode had a one hundred-page script. Muto noted that their main focus while writing was the "...'emotion' of each character". Muto was present during the productions' post-recording sessions, primarily because he believed that it would be easier for the staff to have a writer on-hand in case problems arose during recordings. According to Furuhashi, the script for the series took about roughly ten months to complete, and that thanks to their collaboration with a novelist (Ubukata), the script contained 30 to 40 percent more information than a regular television script. Design and animation Art director Hiroshi Ono stated that he initially could not make up his mind whether to work on this project or not, saying "The information they gave me was enough to see that this was not going to be a straightforward job. The story takes place in Versailles and stretches from France to Russia and England. This means that you can't reuse the same background elements throughout the series, and instead you have to create new ones for each episode. Traveling stories are always the most difficult projects of all." Ono was responsible for the background designs used in the series, and he used photographs and classical paintings as references. 3D CGI was used in the creation of certain backgrounds and settings for the series, such as the Hall of Mirrors. toi8 of Studio 4°C took on the role of designing the weapons and props for the series. He utilized different reference materials for his designs, saying that he "relied on images in books and on the web" as well as films such as Fanfan la Tulipe and The Affair of the Necklace. toi8 was initially asked to work on the series' character designs, but the job was passed on to Tomomi Ozaki due to time constraints. Ozaki noted that Furuhashi requested that the characters "should not look like manga characters or too real; and not too anime-like," and that he wanted the designs to be faithful to historical details. She said that she sometimes referred to historical portraits from the series' time period as reference for her designs, and also cited specific sources for her designs.
