First, I should figure out what "Black Lilith" is. A quick search in my mind tells me that "Koutetsu no Majo Annerose" translates to "Steam Girl Annerose" in English. It's a Japanese anime series or maybe a video game where the protagonist is Annerose. "Black Lilith" is likely a character or a version of a character in that series, possibly an antagonist or a powerful being.
