Term

 * Therianthropy
 * A subhuman with beast ears and a tail. Although not so many on the entire continent, the cohesion between relatives who worship the beast god Zorasu is strong, and it is customary for those who have been baptized in the same temple to help each other as children of the same herd (Kahawi). It is roughly divided into dog ears and cat ears, but they are accused of assassinating the first king, Broccus, who established the unified dynasty of the beast humans in the past.
 * Among the warriors, the higher ranks can consciously open up their potential called "transformation". Even if you have children with the human race, almost all the children born inherit the traits of beasts, and about 1 in 10 people are born in the form of humans. Therefore, those who value bloodlines, such as royalty and aristocrats, tend to avoid marrying a beastman.
 * Very rarely, a child is born that inherits the characteristics of both humans and beasts, even though they are human figures (about 1 in 100). Most people end their lives without knowing that, but only a very limited number of Beastman priests can open the Beastman's trait "royal gate".
 * Europa
 * A large religion where most of the human race is baptized at birth. He preaches a teaching that affirms discrimination regarding beastmen, but he knew the existence of a "royal gate holder" that was actually born between the human race and the beastmen. A magical tool that has the effect of sealing the royal gate, although it is limited, is called a "relic".
