Stanislas is a character from the Marie Antoinette ni Tensei Shita node, Zenryoku de Guillotine wo Kaihi Shimasu segment of the anime series Shūkan Ranobe Anime. Within this narrative, he is identified as one of the brothers of Louis XVI, placing him as a member of the French royal family during a reimagined version of the historical period. The series’ plot centers on a modern-day otaku who is reincarnated as Marie Antoinette and uses her knowledge of the future to avoid the guillotine, primarily by transforming the king and his brothers into an idol group. As a result, Stanislas’s role in the story is directly tied to this central premise; he is one of the royals who becomes part of this idol project, alongside Louis and another brother named Charles. This is confirmed by his participation in a musical number, as an insert song titled Ai no Oto Takaraka ni is performed by the characters of Louis, Charles, and Stanislas.

No reliable direct information exists regarding his specific background, personality, motivations, key relationships beyond his familial connection to the royal court, character development, or any notable abilities.
