Yōko Shirogane

Yōko Shirogane (白金　洋子,), born Yoko Eisenwaren is an anti-hero and deuteragonist,

As well as her metallic hair and nails, one of Yōko's other weapons of choice is a Swiss sabre known as Nagel. Due to her ability to forge metal-based objects from metal at will, she is often in possession of a number of different Nagels at any given time, usually similar in appearance. Aside from these mostly expendable sabres, she kept a particularly detailed model for personal use: Edelweiss.
