During one of the Gears' attacks on the colonies, the young Baiken watched both her parents die before her and ended up losing her right arm and her left eye. However, it was during this chaos when she was able to witness the real culprit behind the attack, the Creator of the Gears. She then swore to hunt "that man" down and seek her vengeance.
Beautiful cosplay! I have never seen this character in the Guilty Gear games I played, but I heard the tatami mat was something of a signature move of hers? Thanks to Wilson for sending this in!
