I forget who it was, but someone named her Gertrude. Here, she is depicted as a bunny just to make her furry, but otherwise she is a little girl that is "noire." In other words, she looks like a black-and-white film character, super-imposed into reality. Don't let her sweet and innocent appearance fool you, though. She has some... We'll call them "quirks."
I would explain what those are now, but perhaps they will be depicted for you sometime in the future.
