The KS is a unit of currency used within the Yamatai Star Empire. KS is the abbreviated form of Kikyou Satsu. Which means “bellflower note.” They are commonly used in electronic form by a KS Card.
KS are also available in a bill form. KS bills are not made of paper; the bills are made of polymer fibers which are combined under precise temperature, pressure and extruded as a rectangular bundle. This bundle is then sliced to paper thinness. The method of manufacture of the material makes them virtually impossible to counterfeit. After the cutting to proper thinness, the sheets are then embossed and dyed with the appropriate images, denomination, and 14 digit-alpha-numeric number. All hard currency is created by the Department of Finance.
