Any guesses on her Sire/Dam? You know, before we solve the mystery for you?
I'd say Sailor Mars, but she's not in public domain yet
I have no clue but this certainly looks like a transformation scene so maybe some kind of magician/quick change artist?
"solve the mystery"...I feel like that's a reference/hint that I'm not understanding.
I'm gonna be boring and guess Sherlock Holmes since we just got a Moriarty.
It seems unlikely given the nature of the costume change, but I'm gonna go out on a limb and say that her sire is Sherlock Holmes
Jareth from the Labyrinth?
Arsene Lupin? Great at costumes, can easily slip into an upper class meeting, rivalry with Moriarty (regarding who's the greatest criminal mastermind)
