A ghostly-masculine and feminine gender in the Spectral Gender System. These individuals feel connected to ghosts, and feels both a masculine and feminine gender connection that isn't the same as a feminime or masculine human gender is.
For example, these individuals could feel small or large connections with the terms bigender and etc, but feel an inhuman connection to a gender that's Ghostly/fully ghost.
Though it isn't exclusive to just ghostkin individuals, as the gender system says, it is an optional term for all spectral identities
