Louis is a supporting character in the anime series Shūkan Ranobe Anime, specifically appearing within the segment Marie Antoinette ni Tensei Shita node, Zenryoku de Guillotine wo Kaihi Shimasu. He is a fictionalized version of the historical King Louis XVI of France. In this reincarnation comedy, the modern otaku protagonist is reborn as Marie Antoinette and, to avoid her looming execution, decides to turn Louis and his royal brothers into an idol group. Louis is therefore a key participant in Antoinette’s plan, serving as both her husband and one of the central members of the new palace idol project. His role is to be molded alongside his brothers into a performer who can win public favor, thus altering the course of history. His personality is not extensively detailed in available sources, but the premise suggests he is initially a somewhat conventional or passive figure who is caught up in Antoinette’s energetic schemes. Over the course of the story, he likely undergoes development as he adapts to the unconventional idol activity, learning to sing and dance while navigating the absurd situation. Key relationships include his wife Antoinette, who drives the idol project, and his brothers Charles and Stanislas, who are also part of the group. Notable abilities are not explicitly listed, but by the logic of the segment he acquires performance skills as part of the idol group. Louis is portrayed by voice actor Toshiki Masuda.
