SHWD

Koga is a new employee at SHWD, a company that "disposes" of Dynamis, or anti-human weapons developed in the last war. In a male dominant environment, she is happy to have a fellow female, Sawada, as her training supervisor. Opposite of her masculine appearance, Koga is very feminine at heart, and is just like any other young woman when it comes to romance.
