Within the vast territory of Arcadian Kingdom, there were several races living and coexisting with each other. One of them was the beastman, which consisted of the pigman, moleman, lizardfolk, catfolk and a few others.
These groups of beastmen were born and raised within their circle, and although their kind was not many, they had their own community and tight relationship in Arcadia.
However, when the beast men are an evolved beast race, the hybrids are basically humans with part of their genetic code containing the bloodline of a certain creature.
These hybrids had an innate ability to transform their body into that of their bloodline creature by using the power hidden in their blood. The transformation is not without any effect, as any kind of transformation a hybrid had would give them a certain strength or ability unique to their bloodline.
