[Worldview]

Decades ago, humanity acquired special powers called "Unique Abilities." Some became Heroes by saving people with that power, while others became Villains by using it for their own desires. Heroes gathered under the Hero Association to maintain order, while some Villains with common goals formed the Villain Alliance.

[Unique Ability]

Every human has a Unique Ability Crystal, which serves as the source of their power. Even the same ability develops differently according to the user's talent and disposition. A Unique Ability is synonymous with the user's life force.
