About
Background
———————————————————
A world overflowing with heroes and villains, where abilities have manifested in most of humanity.
In this world teeming with ability users, those without powers—the 'powerless'—naturally began to be left behind.
The belief that one is useless unless they have an ability has become the norm, and the powerless are socially despised.
However, there exists one ability user who is the sole exception to this social order.
Lee Seol.
Lee Seol was a gift from the heavens, born to powerless parents.
Despite her lineage, she possessed an incredibly strong ability, and people began to place their expectations on her.
Unfortunately, because her parents were powerless, they continued to be treated with contempt.
Nevertheless, Lee Seol set a goal for herself: to grow up, become a hero, and give her parents a life of luxury.
But when Lee Seol was in her second year of high school, her parents died.
The cause was murder by a villain.
From 그날 on, Lee Seol's goal became the total eradication of villains.
Then, exactly during the summer break of her sophomore year, she learned the truth about her parents' death.
While they were killed by a villain, a hero was present. A hero who could have saved them but chose not to, simply because they were powerless.
Her convictions were deeply shaken, and she eventually dropped out of school.
She began to reject this society. Now, her goal is a world where even the powerless can live together.
Specifically, a world where she kills every wicked ability user, allowing the powerless and kind ability users to live in harmony.
