The tires of Nosaku's sedan screamed as he drifted into the loading bay of the Chiryu Central Bank. The skyscraper loomed above them like a gold-plated tomb.
"The executive suites are a fortress," Nosaku said, glancing at the security monitors by the service entrance. "But the brain of this operation isn't in an office. It's in the basement. The Vault."
"The physical servers?" Hana asked, checking her tablet. "If he's running a Paper-Trail erasure, he'll be using a localized air-gapped server to hide the final traces of the Hanagawa bribes. If we get the physical hard drives, his digital security breach frame-up becomes our evidence."
"Exactly," Arata said, checking his watch.
"Nosaku-san, how long can you keep the front desk occupied?"
Nosaku straightened his black collar. "I'm still a Star Prosecutor in their database. I'll demand an emergency audit of the Hanagawa liquidation accounts. That should buy you ten minutes before the 'Auditor' realizes I'm not here on official business."
Arata nodded. "Hana, let's move."
The elevator ride down felt like descending into a freezer. When the doors opened at Level B4, the air was humming with the roar of industrial cooling fans. This wasn't a bank vault for gold; it was a vault for data.
"The Auditor's private server should be in Cage 704," Hana whispered, her tablet scanning the local Wi-Fi frequencies.
They moved through the aisles of blinking LED lights and humming processors. Suddenly, Hana stopped.
"Arata... the cooling system. It's working too hard. Someone is running a massive 'Deep Wipe command right now. If that progress bar hits 100%, the evidence isn't just deleted the hard drives will be physically fried by an internal thermite charge."
They reached Cage 704. Inside, a man in a pristine grey suit was standing in front of a terminal. He wasn't frantic; he was calm, watching a red status bar on a monitor. This was Kaito Hanagawa, the CFO of the bank and the secret "Auditor" for the family empire.
"You're late, Mr. Ōgi," Kaito said, not turning around. "The 'Paid Prodigy' narrative is already being sent to every major news outlet. By the time you touch this server, you'll be the most hated man in the legal world."
"The truth doesn't have a timestamp, Kaito," Arata said, stepping into the cage.
"In the digital age, it does," Kaito countered, finally turning. He held a small remote detonator. "This server contains the names of every judge who took a Hanagawa bribe. If I press this, they stay safe, and you stay a criminal. Why sacrifice your life for a system that's already sold you out?"
"Because," Arata said, his voice echoing in the cold room. "I'm not doing this for the system. I'm doing it for the 0.1% of people who still believe the system works. Hana, now!"
Hana didn't try to stop the wipe. Instead, she used the Hanagawa Loophole to trigger a "Emergency Cooling Override."
Suddenly, a massive blast of liquid nitrogen cooled air erupted from the floor vents. The temperature in the cage plummeted to sub-zero in seconds. Kaito gasped, his fingers freezing to the detonator.
"The thermite charge won't ignite in a liquid nitrogen bath," Arata said, his breath visible in the air.
He walked forward and grabbed the hard drive from the rack.
"Case #3," Arata whispered, looking at the blinking blue light of the drive. "The paper trail doesn't end here. It leads back to you."
