The Sunrider’s chief engineer. She is a seemingly genius scientist who can perform feats of engineering which would be considered impossible by most standards. However, Chigara only nervously laughs and waves away any accolade whenever she pulls off a scientific miracle. Her home world was one of the scientific centers of the galaxy, but was completely destroyed by a micro black hole in the Diode Catastrophe. The catastrophe was believed by experts to be an scientific experiment gone wrong, but Chigara maintains it was the work of sabotage.
