It was discovered that with prolonged usage, the Lost Ones would lose control of their Pure Concepts, bringing disaster and calamity to the world.

Even today, there exists four legendary disasters, dubbed "Human Errors", which effects continuously rage on: the Sword of Salt, which turned the whole Western continent into salt that is gradually melting into the sea; the Pandæmonium, a fog-like dead zone in the Southern archipelago from which monsters regularly emerge; the Mechanical Society, which controls the wild frontier in the East; and the Starhusk, which carved out the center of the Northern continent and set it afloat.

To prevent such calamities again, the summoning of Lost Ones has become strictly forbidden and heavily managed by the Faust, a class of Church members in society.

Top-class Executioner Menou has been tasked with eliminating Akari Tokitō, a Lost One who has been summoned by King Grisarika of the Noblesse, the noble class.
