Atsuko has blonde hair that ends in two extremely long pony tails, both held by a small red and black chequered bow. She has a straight fringe which is kept in place by two clear bobby pins at the left of her forehead. Her eyes are bright blue, and usually wide open, and she has very light skin. Her apparel consists of a thin white tank top, usually covered up by a long sleeved black, buttoned up coat with a pocket on the top left. A small bow tie is positioned below her neck, which has a plastic skull emblazoned on top of a red ribbon. A chequered, small skirt covers her legs, with two small straps on either side. On her feet are long leather boots that almost reach to her knees.
