Note from The Future: I’m told that, in Doc’s Story, the demon’s name is given as Azmodeus. (Also, she and Hitler are implied to be Schrödinger’s parents. Yyyyeah.) None of this info was going around English-speaking fandom in the Shine-writing days, so Nina got a lot of details made up.
Nina: Oh. Oh, this is good. I’ve been locked up for so long…then my consciousness was scattered across the universe…
…but it’s all over now! NINA is back!
Alucard: You’re a demon of Hell and your name is Nina?
Nina: You wanna fight about it?
