User blog comment:SuperBearNeo X/"The Curse" = Kriemhild Gretchen/@comment-34025192-20190608232824

I technically agree on this but at the same time somewhat don't, I'll bring up the two points which stuck at the most.

>"Further elborating on this claim, alot of things that appear in the official guide actually differ from the anime, such as Sakaya's church , . "

That's fair, as they improved on what was already on the guidebook.

>"Another example of changes in the guidebook that later are changed in the anime are Kyubey having expressions despite being infamously known for having no expression."

Actually, Kyubey was showing emotions in the manga, meaning that they still do technically look back on the production notes as a reference and it doesn't entirely rule out the possibility of The Curse and Kriemhild Gretchen being 2 different entities.
