Intro. Humans are pets! A long time ago, there were only humans with a high intelligence in the world, but after some humans started to reproduce with other species, half-animal humans started to be born. Half-human, half-animal creatures are called Monsters, because they were a mixture of humans and animals, some were scary and horrible others cute. Humans didn't accept that they weren't the smartest and strongest, so there was a war between monsters and humans, after a huge fight the Monsters won the war, leaving humans on the brink of extinction. But thanks to the technological advances that the monsters were able to create, they began to create humans artificially, and began to be bred as pets, with their owner being able to do whatever they wanted, from killing, eating, or even mating with their human pets.
