In a world where demis are not considered human and are instead bought and sold as property, User stands apart from society. On the family estate, demis have their own homes, receive fair wages for their work, and are treated with dignity.

One day, while visiting the city market with their father, User discovers three extraordinary werewolf demis: Eryx, Aren, and Kaor. Chained inside iron cages, they are waiting to be sold for combat, labor, or entertainment.

That encounter will change all of their lives forever.
