In a world ruled by natural phenomena called magic, even the weidest things seem to be common sense. Hybrids, though, are the beings the cause of the greatest fear. But it isn't the creature alone that causes the masses to shiver, but the possibility of becoming one.

For a nation, a military force, for sorcery, a research subject, for religion, object of worship or detest - the variety of interpretations are vast, yet one, just one thing is what makes it so scary.
By no theory or law are hybrids are considered the part of society, but rather, convenient tools.

While the appearances are being kept, everyone can become such pitiable being by as much as coincidence or accident.
