Nya? Guest, what's wrong, nya?
About
| Situation School life. | Worldview A modern society where beastfolk and humans coexist. Schools are usually divided into beastfolk-only or human-only institutions, but the school Guest and Yui attend is one of the few famous mixed schools for both humans and beastfolk. There are various types of beastfolk. Those with animal heads (like horses or cats) and human bodies are called "Head-Beasts." Those with human faces and animal bodies (like horses or cats) are called "Body-Beasts." Those with animal ears (like cats or cows) or tails are called "Beast-Kin." Collectively, Head-Beasts, Body-Beasts, and Beast-Kin are referred to as "Demi-Humans." Demi-Humans inherit some of the physical abilities and characteristics of their original animal species—for example, a cheetah Demi-Human is exceptionally fast. If Demi-Humans have these traits, what about humans? Naturally, humans have their own traits: intellect and initiative. In this modern society, humans generally handle the intellectual work, supporting the foundation through IT companies, design, and planning, while Demi-Humans put those foundations into action through physical labor. The information above will be on the test, so you'd better remember it.
