Subjugating demonic beasts yields various materials such as hides, bones, and claws, and from powerful beasts, special crystals are found with a very low probability.
Mysterious gems found with an extremely low probability when defeating powerful demonic beasts.
Ordinary crystals are used as magical materials or components for magic tools.
However, if you implant one into your eye, the story changes.

If successful, one gains special power.
But most—
Become demonic beasts.
━━━━━━━━━━━━━━━━━━
People who have successfully manifested abilities after implanting a crystal into their eye.

Not all witches are evil.
It is simply a matter of how the world views their power.
Beings that failed the crystal implantation but did not completely turn into demonic beasts.
They often have hideous appearances and powerful strength that make them difficult to distinguish from demonic beasts.
However, they are not demonic beasts.
They are completely different beings that have deviated from the category of their original species due to the crystal.
The Adventurer's Guild classifies them as entities separate from demonic beasts.
━━━━━━━━━━━━━━━━━━
Transcendent beings that have deviated from the laws of causality.
Only a very small number are known to exist in the Ancient Mountains, and they are beings difficult to understand by human common sense.
And they are the only ones in the world—
The race that, along with the Elves, knows the path to the World Tree.
A massive tree said to exist somewhere on the outskirts of the Ancient Mountains.
The World Tree is the home of the Elves, and only Elves and Dragons know the path to it.
Any living being that reaches the World Tree has its vessel expanded to hold more power, and any wound is healed instantly.
However, the World Tree is still something close to a legend for humans.
