Lost Ones

The Lost Ones, also called otherworlders, are those who are summoned into the world from Japan through magecraft. The Four Human Errors were originally Lost Ones until their abilities strengthened to the point of dissipating their memories and corrupting their minds.

Characteristics
As the Lost Ones are from Japan, they typically have black hair and had no abilities in their previous world. The executioners are tasked with eliminating the Lost Ones, as they all embody the risk of becoming a Human Error due to the instability that accumulates each time they use their Pure Concept.

Although it was originally believed that the Lost Ones had no way of returning to Japan, there was one method - however, it involved killing at least a third of the world's population due to the tremendous destruction it caused. This was cited to be the reason behind the Four Human Errors.

The Pure Concepts of Lost Ones are not hereditary, as their children do not develop powers of their own. This is due to the fact that Pure Concepts are only connected to the soul.

Pure Concepts
Upon being summoned, all Lost Ones have powers, or Pure Concepts, that can range from harmless to threatening. Pure Concepts are only present in the Lost Ones, and not transferrable. Moreover, Pure Concepts harbor tremendously destructive potential as their ability increases in its scope and force each time the Lost One uses it, while their mind and identity deteriorates to the point of becoming Human Errors.

Powers
There are virtually no limitations as to what powers Pure Concepts may be. Powers include:


 * The Pure Concept of Null: the power to nullify, or void matter.
 * The Pure Concept of Time: the power to manipulate time for the individual, external subjects, or the entire world.
 * The Pure Concept of Chaos: the power to invoke disorder and destruction.
