The standard paint scheme for the Ghost regiments begins with a base coat of gray so light that it appears almost white. The Second Ghost’s warriors use dull orange accenting. To remind them of their lives in the yakuza, they also decorate their Mechs with full-body designs. The Second’s design is koi fish scale patterns, with some warriors adding swimming fish. – Canonized by Dak, 2014.
