The available sources for the anime series "Meiken Jolie" (Belle and Sebastian) contain no record of a character named Diana. Character lists consistently feature Sebastian, Belle, Poochie, Cecil, Anne-Marie, Isabel, Sarah, Dr. Guillaume (Dr. Phillips), Mr. Albert, Robert, Maria, and others while omitting Diana entirely. Her absence persists across all documented contexts: narrative descriptions, episode synopses, and production credits remain devoid of references to Diana. This lack of information extends uniformly through plot summaries, episode guides, and character compendiums.
