Rum

Rum is the living doll assigned as the face for Shirley. She is very timid and barely speaks, afraid to upset others; eventually, Emilico's contagious joy helps bring Rum out of her shell a bit. Rum has a weaker bond with her shadow master than other pairs. She has an imaginary friend named Rummy, focused in her left index finger and represented by a black ribbon(Shirley has a matching white ribbon). She crooks her finger slightly when "talking to" Rummy. During the Debut arc, Rum is revealed to have very good photographic memory.

During the debut test's garden trial, Rum breaks down in tears and confesses to Emilico that Shirley hadn't even given her a name, and that Rum is the name she gave herself.
