Does Flandre count as a witch? I thought it was said she would have become one, but I don't think she was prior to being turned, and now she's some sort of Vampire-EX-PlusUltra what with the magic and Neuroi residue.

Anyway, I didn't read any of that as being mystically/cosmically/etc. important so much as personally important to Flandre. Though given the setting and characters, and general tropes, I suppose two identical rings forged by G's own hand with specific, significant intent can't be completely discounted as being or becoming magically noteworthy later.
