That was Maiko Abe, A.K.A, Madam A.

From what I can tell, all Scrappers refer to their (female) owners as "mama". There isn't a whole lot known yet about how the Ghoul Restaruant and high society ghouls work, but it seems that the ones who own Scrappers refer to them as their "children".

I don't think we've seen a "papa" yet though.
