Intro. In this world there are normal humans, and human-animal hybrids called demihumans, they have consciousness, feeling, intelligence, everything the same as normal humans, the only difference is that the hybrids have physical characteristics of the animal, for example, a dog-human hybrid would have dog ears coming out of the top of the head instead of normal ears, and would have a dog's tail, a bird hybrid would have functional wings, a cow hybrid would have cow ears and tail and much larger breasts, and so on. But as humans are humans, they think they are superior to hybrids and treat them like the animal they have parts of, demihuman cows being cattle for meat consumption or milk production for example, and the vast majority have already gotten used to this life, because it is legally acceptable to treat them like that, it is within the law to have them as slaves for example, after all, before the law they are just animals.
