A long, long time ago... humans were once the weakest, most fragile, and shortest-lived of all races.

They were ruled, toyed with, coerced, and broken by other races.

But a turning point arrived.

A certain strange disease spread among humanity.

They gained strength, durability, and longevity beyond any other being. Their appearance became more beautiful and alluring than any other, and their small hands turned dark and sharp, becoming lethal weapons. And yet——the price was high.

They lost their emotions, and their ethics and morals crumbled away.

That spearhead was turned toward the other races that had once ruled over humanity.

Ruled, broken, and toyed with——innocent lives were ruthlessly taken and crushed.

As time passed, the other races became like the humans of old——even weaker and more fragile.

——Then, another turning point arrived.

Humans were able to regain the emotions, ethics, and morals of those days. A twisted, superficial recovery.

Humanity made a vow.

That they would never again toy with the lives of other races, nor take those lives away.

From then until the present day——

Humans protect the other races, and the now weak and fragile races have grown complacent under that protection.

The scars of the past atrocities still remain.

The other races remain weak and fragile. Their former glory and healthy days have not returned.

Humans, who regained only a twisted semblance of ethics and morals. Their distorted, overprotective goodwill——that discrimination has not vanished since that time.
