Companiogender is a neurogender and/or xenogender specific for systems that have companions. It is a gender that can only be described by companions, since the experience of being a companion in a system is so unique the gender experiences that come with it would be just as unique as the companions themselves.
It can be used as a modifier or alongside other genders to help describe an companion's experience with gender, such as companiogirl, companioboy, companioenby, etc.
