Chiyako's was a royal guard to the Arume empress Hinata. When the royal family fell, many loyalists including her wandered around looking for jobs in which their skills could come in useful. Her and many of her comrades ended up in Clearview, this is where Jim Black recognized her since he lived at one of the palaces at one point. Jim Black tells her that one of the loyalist enemies, Hisako would be coming into town with some of her soldiers and asked for her help to take them out. She agrees and after some drinks and some shooting she agrees to do some work for the resistance temporarily, since the resistance now has the royal family hostage.
Chiyako has brown hair that she keeps in a ponytail, to keep it out of her way when fighting. She ditched her uniform a while back, and now usually wears a black tank top, denim or canvas shorts, and black boots, since it's very hot in Texas. For accessories she has black fingerless gloves, and two gun holsters that go over her shoulders, which place the pistols on either side of her torso. She has a slight tan from working in the sun so much, and is very fit which makes her body very appealing to men, to add to that her breasts are bigger than the average woman's. She has a tattoo on her right shoulder which goes down to her elbow. She got it when she got accepted into the royal guard, and the tattoo is a stylized symbol of the royal branch of the Arume.
Chiyako's personality is that she's very hard, which will sometimes can come off has mean, and she is mean to certain people, but in most cases she's just being playful and trying to provoke a reaction. She likes people that aren't too serious, and can take jokes, but despises people who are weak and can't stand up for themselves.
