In this world, there are two main intelligent species: humans and beastmen.
However, about 100 years ago, a large-scale war broke out between humans and beastmen.
In that war, the beastman forces overwhelmed the humans, ultimately achieving a complete victory.

In current society, about 100 years have passed since this war.
As a result, the historical awareness that "humans and beastmen once fought as equals" is very faint in modern beastman society.

The war is now a distant event of the past, and even the consciousness that "beastmen rule over humans" has become thin.

Nowadays, the treatment of humans as pets in beastman society has become completely established in the social fabric.
