The white chemical fog hissed from the ruptured valve, filling the warehouse with a thick, choking veil. It was the perfect cover and the perfect metaphor. In this city, the truth was always obscured by a cloud of power and influence.
"Thermal vision!" Nosaku's voice barked through the haze, stripped of its usual calm elegance. "Don't let them reach the perimeter!"
Arata grabbed Hana's hand, pulling her through the labyrinth of crates. He knew this layout. He had spent his childhood summers playing in the industrial zones of Chiryu, back when the Hanagawa Group was just a local manufacturer and not the sprawling conglomerate currently pulling the strings of the city's legal system.
"This way!" Arata hissed, ducking behind a stack of pallets labeled with the Hanagawa logo a stylized blossom that now felt like a brand of corruption.
They reached a narrow maintenance crawlspace. As they scrambled inside, the heavy thud of tactical boots echoed on the metal catwalk above them. Red laser sights cut through the fog like hungry eyes.
"Arata-san," Hana whispered, her breath coming in ragged gasps. "The logbook... if the Hanagawa Group is providing the tech and Nosaku is providing the legal cover, this isn't just a murder. It's a corporate hit. Yatsurugi must have found out they were using the Shinjuku heroin bust to fund their remote-trigger research."
"Exactly," Arata said, his eyes hard. "They didn't just kill a detective. They turned the Evidence Room into a laboratory. If we can prove that 'sugar-polymer' came from a Hanagawa lab and that Nosaku signed off on its transport, the 'Locked Room' isn't a miracle anymore. It's a crime scene with the Prosecutor's signature on the wall."
They burst out of a side fire exit and into the pouring rain. The salt air of the Aichi Chiryu docks hit them, cold and bracing. Their battered office car was a hundred yards away, but a black sedan was already idling near the exit, blocking their path.
Arata didn't stop. He sprinted toward the pier instead.
"The car is the other way!" Hana cried.
"The car is a trap!" Arata shouted back. "Look at the license plate!"
Hana glanced back. The plate was a government series. Nosaku hadn't just brought private security; he had brought the "shadow" of the Ministry. If they got into that car, they would never reach the Yatsurugi office.
They reached the edge of the pier, the dark waves of the bay churning below. Arata pulled his notebook from his pocket, wrapped it in a waterproof evidence bag, and shoved it into Hana's coat.
"Go to the old lighthouse at the end of the district," Arata commanded. "My contact is there. Give him the notebook and the cloud decryption key."
"What about you?" Hana's eyes were wide with terror.
"I'm going to give the Red Viper exactly what he wants," Arata said, a grim smile touching his lips. "A target."
Arata stood alone on the pier as the fog began to drift out over the water. The sound of the sedan's doors opening was heavy and final. Four men approached, their silhouettes sharp against the warehouse lights. In the center, strolling with a casual, terrifying confidence, was Shin Nosaku.
He had ditched his suit jacket, his dark red vest stark against his white shirt. He looked less like a prosecutor now and more like a high-stakes gambler about to go all-in.
"Valiant, Arata. Truly," Nosaku said, stopping ten feet away. "The 'Zero-Percent Lawyer' making a final stand on the docks of his hometown. It's a poetic ending. A bit cliché, perhaps, but the public loves a tragedy."
"The only tragedy here is your career, Nosaku," Arata said, his voice steady despite the rain drenching his hair. "I've seen the logbook. I've seen the Hanagawa blueprints. You didn't just hide the truth; you built the lie with your own hands. How much is the Hanagawa Group paying a Star Prosecutor these days? Or did they just promise you the Minister's seat?"
Nosaku's expression didn't change, but his eyes turned into chips of ice. "The Hanagawa Group provides stability. They provide the 'Order' that keeps this city from tearing itself apart. If a few detectives have to be sacrificed to ensure the next generation of security tech is perfected, that is a price the State is willing to pay."
"I'm not the State," Arata said, taking a step toward the edge of the pier. "And I don't accept your price."
"Then you'll accept the verdict," Nosaku said, raising a hand. "Search him. Find the device. If he resists... well, the currents in this bay are notoriously unforgiving."
As the guards closed in, Arata reached into his pocket. He didn't pull out a phone or a weapon. He pulled out a single, crumpled 100-yen coin the change from Case #1.
"Hey, Nosaku," Arata called out. "You said miracles don't happen 900 times. You're right. They don't happen because of luck. They happen because someone finds the one thing you forgot to bury."
Arata flicked the coin into the dark water and, before the guards could reach him, he vanished over the side.
