Elden Ring - The Malenia Conspiracy
I've been asked about this theory since some of the earliest days of Elden Ring's launch, and for the longest time, I didn't have any real answer to give, but I finally realized there's one potential thing that might give some additional insight on this, although it might seem like a ridiculous way of checking.

Special thanks to Last孤影众, who imported Malenia's model and animations into Sekiro.
