Some time before the story started, Marble opened the item shop "Marble's" in Palmacosta and has since then run it together with the family, her daughter Cacao and her husband, as well as her granddaughter, Chocolat, who she was very close to. Between this and the start of the story, she was taken by the Desians for openly opposing them, and was eventually taken to Iselia Human Ranch. There, she was given an Exsphere and forced to work. Not long before the present storyline, Marble somehow met Genis Sage while he was sneaking around outside the ranch. They got along well, and they managed to meet each other in secret without the guards knowing, in which Genis often would give Marble his lunch.
