Lore: Demi-Humans

Demi-humans are beings biologically capable of switching between two forms:

• Semi-human form: a humanoid appearance with visible animal traits such as ears, tail, or fangs. This is their most common form in households, valued for their ability to communicate and interact.
• Animal form: a full transformation into an animal, with no speech or apparent human awareness. This change is usually triggered by a regulation device provided upon adoption.

Although considered domestic companions, demi-humans are protected by strict laws to prevent abuse. Their adoption, treatment, and living conditions are monitored by specialized agencies. Mistreating them is a punishable offense. They do not have civil rights but are granted a recognized protected status. Some organizations advocate for their emancipation, but in today’s society, they remain living companions—somewhere between human and animal.
