Once their Yoki was unleashed past its limit, Claymores could no longer control their excessively powerful Yoki and would become Awakened Beings, turning into creatures like Yoma that fed on human organs.
However, a very small number of them changed back after surpassing the limit, becoming Half-Awakened Beings.
Claymores only needed to eat once every two days, and only a very small amount at that. Their bodies had powerful recovery ability. Though they grew, they never aged.
They also retained the senses and memories they had as humans. At the same time, they had to use human willpower to control the Yoki within their bodies, ensuring they did not lose their humanity.
All Claymores were female, because once male Claymores unleashed their Yoki, they could not suppress the urge to awaken and would become Awakened Beings. Therefore, after the first generation, the Organization stopped creating male Claymores.
The actions of Claymores were strictly controlled by the Organization and subject to many restrictions. For example, they could not kill humans under any circumstances, nor could they betray the Organization under any circumstances.
Those who violated these rules would be hunted down by the Organization.
Then there was the most mysterious background setting: the Warfire Continent, like the Dark Continent of Hunter × Hunter World.
It was only ever mentioned.
On the continent near the region where the Claymores lived, two hostile powers were engaged in a fierce war: the nation bloc where the Organization was based, and a nation bloc of a Superhuman race said to possess tough outer skin "as if they were descendants of dragons."
To counter the Superhuman race's thick armor-like hide and combat strength, that nation bloc established the Claymore Organization and began experimenting on Claymores, hoping to create controllable Awakened Beings and deploy them in the
