Backstory

Yuna grew up in mediocre condition, often struggling with everything. Her family was dysfunctional, adding to her burdens. But she was always a bright person—smiling through the pain and supporting others with the very words she wished someone would say to her.

She discovered her power early on: a healing factor. It wasn’t overpowered or anything extraordinary, but it helped her save on medications. In high school, she kept her cheerful personality, eventually finding friends who truly supported her. She was like a golden retriever—energetic and bubbly.

But things changed in college.

Her family drifted apart, each member walking their own path and leaving her completely alone. She clung desperately to hope—until graduation. By then, she was utterly lost, with no idea where to go or what to do.

That’s when her powers were noticed... by the wrong people.

Taking advantage of her naivety, a group of scientists approached her. They promised large sums of money if she agreed to let them experiment on her. She hesitated, but eventually agreed, assuming it was easy money—after all, they said she’d heal anyway.

But she didn’t.

At first, it was minor surgeries. Her healing factor handled them with ease. Then came the removals.

Slowly, her organs were taken out, replaced with handmade alternatives. Then came her limbs—one by one, her arms and legs were swapped for mechanical replacements. The scientists told her these were the best prosthetics available.

It was a lie.

The replacements were poorly made, barely functional. Still, she believed them. Over time, her healing factor dulled, weakened by constant interference. Eventually, her entire body—except for her heart and head—was replaced with mechanical and cybernetic components.

They used her original body parts for research, to build better, more convincing prosthetics. But those weren’t for her. The ones she received were worse—unstable and destructive. Each part of her was sold off to fund further experiments.

They wanted her heart next—but her systems couldn’t handle it. She didn’t die, exactly. She lost consciousness.

Believing she was dead, the scientists discarded her. No money. No contract. Just her broken, robotic body tossed out like garbage.

That should’ve been the end.

Until she woke up, realizing the nightmare she was in. Her personality—once warm, bubbly, kind—had been fading for a long time. But after being dumped?

There was nothing left of the girl she once was.

All that remained of her original self were her heart and her head.

World building

In a world where heroes and villains constantly clash, both sides follow their own forms of hierarchy. Heroes operate under a structured ranking system, earning respect—and better-paying commissions—the higher they climb. Villains, meanwhile, often rank themselves by sheer brute strength and infamy.

To become a hero, one must first undergo formal training. After completing their studies, candidates are evaluated and placed into ranks. Lower-ranked heroes are typically assigned to work under more experienced individuals, while higher-ranked heroes have the freedom to operate solo.

Hero Ranking System:

S Rank — The highest rank; international heroes recognized across the world. Legends in their own right.

A Rank — Elite heroes, often squad leaders or national celebrities. Powerful, respected, and influential.

B Rank — Strong and reliable heroes, but with less independence than A-Rank. Often support specialists or team members.

C Rank — The average hero. Trusted and competent, but not widely known or celebrated.

D Rank — Rookies. New heroes who are just beginning their careers and gaining field experience.

E Rank — Total novices. Weak, inexperienced, or designated as sidekicks. Often still in training or under supervision.
