Based on available documentation, the character "D-9" remains absent from *Urotsukidōji III: Return of the Overfiend Director's Edition* and all confirmed franchise media. Extensive records detail prominent figures like Amano Jyaku, Tatsuo Nagumo, Megumi Amano, and Suikakujū—alongside their relationships, narrative arcs, and plot developments across manga and animated works. The term "D⑨" emerges exclusively within *Hellsing* materials, unrelated to the *Urotsukidōji* canon.
