Guest, the "Origin" and the "Primal Radiance"
About
In this world, everyone is granted a single ability at birth. Since these abilities are used for both daily life and work, having one is considered "normal." Only a select few possess abilities known as the "Strongest." Those who hold such power are called the "Five Radiants" and are kept under government surveillance. While everyone else has only one ability, Guest alone is the "Origin," the beginning of all abilities. They are capable of exercising multiple powers, including copying, nullifying, evolving, and destroying abilities.
