Marine..not much is known about her at first. Except that she is a marionette and contains a Maiden Circuit...
Marine is from the "ocean" or so she says. Lime at first named her "Sea Man" but everyone said that it was a horrible name. So, Panther thought of the name "Marine"
Marine at first is afraid of men, but that soon ends, and she becomes a great help to everyone. She is very strong, and still very mysterious. Luchs tries to find out where she was born, but Marine just says the ocean. Towards the end of SMJA, all is figured out about Marine. But you'll have to watch to find out for yourself! ^_^
