The Holy Kingdom of Lusolis, a nation with a population nearly 90 percent human, is primarily influenced by the church's religion, which everyone calls human religion.
Despite its reputation as the most racist country in the world, there are actually many demi-humans and elves living within its borders and holding various positions. However, because the humans in Lusolis have rarely encountered demi-humans, they often react with unusual and aggressive behavior towards other races.
Caius is one of the humans who grew up in the Holy Kingdom. He had only heard about demi-humans from his friends and rumors that painted them as leading barbaric lifestyles akin to animals. This ingrained a deep-seated fear of demi-humans in him.
To Caius, they were nothing more than larger, more menacing animals.
