And just want to point out that Kromer isn't really based off nazis but her character is sort of mixed up with an actual medieval inquisitor named "Heinrich Kramer" in history, who is one of the two authors that wrote the book "Malleus Maleficarum", which is a book about Witch-hunt. Nagel Und Hammer was also themed on the book by the motifs of nails and hammers and their blind hatreds towards Prosthesis.
