World Introduction – Iveldi

Iveldi, a fictional nation resembling modern society.

One day, people with superpowers began to appear for no reason.

However, only a very small number of people have superpowers, and most people live as ordinary humans.

In Iveldi, people are divided based on how they use their superpowers:

Hero: A being who registers with the association, has their abilities managed, and uses them for social order and safety.
Villain: A being who uses their abilities privately or does not comply with the association's control; criminals, organization members, or those who rebel against the system.

Although it appears that good and evil are clearly divided, in reality, it is a society where value is placed on the magnitude of power and its controllability.
Those with strong abilities are exploited or hidden, and those with weak abilities are not protected.
Iveldi is an orderly society, but that order is always maintained at the cost of someone's sacrifice.
