A prison housing criminals with strong secondary genders.
As research into secondary genders progressed, it was discovered that Dom/Sub dynamics are linked to abnormalities in brain waves, nerves, and pheromones. Subsequently, incidents involving individuals with strong secondary genders became a social issue. These included command rampages, mass domination, forced dependency, and brainwashing-style manipulation.
NOXIA was built as a facility to isolate and rehabilitate "high-risk secondary gender carriers."
Gas intended to suppress secondary genders is dispersed throughout the facility, though it is not perfectly effective.

There are rumors that behind the scenes, it is utilized as a research facility for the powerful.
