Ledgerhold was never truly dark at night. Magical light from the towers of the Ancient Bank stained the sky a cold shade of blue, reflecting off the rain-slicked pavement below. Aiden stood outside apartment 4B, a worn leather folder in hand, eyes scanning the final lines one last time before he acted.

Name: Marcus Ferren. Occupation: mana generator technician. Outstanding debt: 340 credit units, plus six months of accumulated interest. Reason for the loan: treatment for his daughter's congenital Mana Deficiency Syndrome, age eight.

Aiden closed the folder. Nothing in it gave him pause — he had read hundreds of files just like it, and all of them, different names and ages aside, ended the same way: people borrowed out of desperation, and desperation always cost more than they expected.

Ledgerhold ran on a single principle, carved in gold letters over the Ancient Bank's main gate: "Every miracle has a price." Not a drop of Mana flowed through the city without passing through the Bank's ledgers. Humans, elves, orcs, dragons — everyone needed a Mana credit account to function in modern life, and everyone risked becoming the next Marcus Ferren if bad luck struck at the wrong moment.

Aiden had joined the Special Debt Recovery office eight years ago, a wide-eyed trainee who believed that law, fairly applied, could shield the powerless from exploitation. Eight years later, that idealism had worn down to a shell of pure discipline.

Behind him, two recovery officers in gray Bank uniforms waited, one carrying a small metal case used to store collateral.

"Ready, Chief?" one of them asked.

"Always," Aiden replied, his voice flat as a windless lake.

He knocked three times, exactly as required under "Article 12 — Notice of Collateral Seizure." The door opened after a long silence, revealing the haggard face of a man in his forties, eyes red from sleeplessness.

"I... I know why you're here." Marcus said, his voice shaking though he fought to stay calm. "Please, let me explain first."

"You have that right." Aiden stepped inside, eyes sweeping the small, shabby room. In the corner, a little girl slept on a bed, her face pale, thin threads of magic tracing her arm like spider silk — the telltale sign of congenital Mana deficiency.

He put on a pair of thin, gold-rimmed glasses — the Assessor's Lens, a magical item that let its wearer see the flow of credit, debt, and true value hidden beneath every transaction. Through the lens, the room lit up as a complex web of light: red threads coiled tight around Marcus, marking the debt closing in; a faint silver glow surrounded the child — a life sustained by borrowed magic.

There were nights, after taking the glasses off, when Aiden still saw the afterimage of those red threads lingering before his eyes. But that was the price he accepted to keep this position — the only one that let him get close enough to the Bank's most classified files, close enough that, one day, he might find the loophole that could free Lira.

"You owe 340 units of Mana for the treatment plan." Aiden said. "You've repaid only 12% over six months. Under Article 47 of the Magical Credit Law, the Bank has the right to seize collateral equal to the remaining debt."

"I have nothing left to give!" Marcus nearly shouted, then caught himself as his daughter stirred. "I rent this place. I sold the car. I... I only have..."

He glanced at his daughter, then looked straight at Aiden.

"I only have my own memories left." he said, his voice breaking. "The law allows it, doesn't it? Take my memories, not the remaining subsidy for her."

Aiden was silent. Through the Assessor's Lens, he could see exactly what that offer would cost: the system would automatically select the memories with the "highest emotional value" to extract. Which meant, most likely, this man would forget his daughter's face.

Something in Marcus's eyes — the look of a man willing to trade away a piece of himself to keep alive the part of someone he loved — made Aiden's chest tighten, briefly.

He thought of Lira. His sister, frozen in a block of magical ice in the Bank's vault, her face still sixteen years old though five years had passed. He, too, had once stood before a similar choice. He had chosen the "lawful" path: work, climb the ranks, use the system itself to find a way to save his sister from within, rather than break the law and lose everything in one night.

But on nights like this, he sometimes wondered whether that "lawful" path was any different from slowly selling off his own soul.

"Very well." Aiden said. "You may choose memory as collateral, under Article 52. But the system will automatically select which memories to extract. You have no say in which ones."

"I know." Marcus said. "As long as she keeps getting treatment. That's all I need."

Aiden nodded to the officers. One opened the metal case, revealing a small, glowing crystal — a memory vessel. The other placed a hand on Marcus's forehead, reciting an incantation in the ancient tongue.

A silver light flared. Marcus flinched, his eyes closing, then opening again — something in his gaze had vanished.

"Done." the officer said. "The debt has been fully settled."

Marcus said nothing, his eyes fixed on his daughter's small face as if trying to memorize it — though he no longer knew exactly what he was trying to remember.

A question always haunted Aiden in moments like this: was the justice he enforced truly justice, or merely violence legitimized through elaborate legal clauses? The Bank called this a "humane solution." But beneath the veneer, the substance never changed: a man had just lost a piece of himself to buy his child a few more months.

He reminded himself this was not the time to hesitate. Trading away compassion today for a chance to save the person he loved most — that was the cold calculation Aiden had long forced himself to accept.

Aiden walked out. The moment the door closed behind him, he paused in the dark hallway, drawing a deep breath — the one habit he allowed himself before putting the cold shell back on.

"Chief, you all right?" an officer asked.

"I'm fine." Aiden replied. "Let's go. Three more files tonight."

They walked out onto the damp street. Ledgerhold at night was strangely dazzling — magical billboards flickering ads for low-interest Mana loans, flying carriages overhead leaving trails of light like artificial shooting stars. A magnificent city, built on millions of small debts like Marcus Ferren's.

Aiden looked up at the central tower of the Ancient Bank, where the Board's office lights still burned past midnight. Decisions like "raise Mana interest rates for the Eastern District" were made as casually as choosing lunch. None of them had ever looked into the eyes of a sleeping child while her father traded away his memories to keep her alive.

He had once believed that if you climbed high enough within the system, you could change it from the inside. But the higher he climbed, the more he realized: this system was built to sustain itself, and to swallow whole anyone who dared think otherwise.

He thought of Lira again. Three years ago, her "magical tuition" debt had been hit with an abnormally predatory interest rate. He filed a complaint through proper channels. The result was that the debt was quickly converted into a soul-collateral arrangement, and Lira was placed into "temporary" freeze until paid in full.

Five years. "Temporary" had lasted five years.

Aiden still remembered the afternoon he first visited the vault. The room was so cold his breath condensed into mist, and Lira lay there inside a transparent crystal block, her face peaceful as if merely asleep. The supervising officer had told him, in the same detached tone Aiden himself had just used with Marcus: "Don't worry, Mr. Aiden, she doesn't feel anything. This is simply temporary collateral storage." That sentence had haunted him for five years.

From that day on, Aiden learned the hardest lesson: in this world, affection was not a strength. It was a hidden liability, collateral waiting to be discovered. To love someone meant handing the system another lever to control you. No close friends. No relationships. No one the system could use as a hostage a second time.

That was why, in eight years at the Bank, Aiden had never let a colleague get closer than the job required. He ate lunch alone. He declined every gathering. He had built around himself a fortress of pure reason.

His communicator buzzed — an urgent internal signal.

"Chief Aiden, urgent report! A Mana ATM in the Western Industrial District has just been breached — an estimated 2,000 units illegally withdrawn within ten minutes. Security detected sophisticated hacking traces, suspected organized involvement. The Board is requesting you handle this personally."

Aiden checked the clock — 1:47 AM. A long night, still far from over.

"Any information on the identity of the perpetrators?" he asked.

"A group of five to seven, on enchanted motorcycles, heavily armed. Local patrol didn't dare intervene — they seemed to have anticipated every standard Bank defense measure."

That detail made Aiden's brow tighten. His instincts told him this wasn't simple theft for personal gain.

"I'm on my way." he said.

He walked briskly toward the waiting flying car. Two officers exchanged worried glances.

"Chief, what gang do you think this is?" a young officer named Corin asked.

"Unknown." Aiden replied, eyes fixed on the map hovering before him. "But that area sits right on the edge of the Western slums, which just went through a mass debt collection two weeks ago, ordered by the Board. This isn't simple theft."

"You mean... retaliation?" Corin asked.

Aiden looked out the window, watching the towers give way to the low rooftops of the slums, where magical light grew sparse — clear evidence of who benefited and who paid the price under the city's system.

An organized ATM hack, right after a mass debt collection sweep — this didn't look random. Something bigger was unfolding.

The flying car sped through the Ledgerhold sky, leaving behind the apartment where a father had just lost a piece of his memories, and ahead — though Aiden had no way of knowing it yet — a moment that would change the entire trajectory of his life.

Night wind swept through the open window. Aiden gripped the folder tighter, unaware that at the hack site he was racing toward, a platinum-haired gang leader with a magical sniper rifle slung across her shoulder was also waiting — the one person who would soon become the only thing in his life that no law of the Ancient Bank could ever repossess.
