The holding cell was at the Shinjuku police station — the same building where Ren had first met Captain Ishida, the same gray walls and fluorescent lights that had made him feel so small. But this time, he wasn't sitting in the lobby. He was standing behind a one-way mirror, watching Detective Watanabe question one of the men from the warehouse.
The man's name was Ishikawa Taro. He was forty-two years old, with a shaved head and a neck tattoo that disappeared into his collar. His hands were cuffed to a metal ring on the table, and his eyes — dark, flat, empty — stared at nothing.
Watanabe sat across from him, a file folder open in front of her. "You've been identified by a witness, Ishikawa-san. The woman you kidnapped. She's willing to testify."
Ishikawa said nothing.
"The other men in your crew — we picked up three of them last night. They're in cells down the hall. They're not talking either. Not yet."
Still nothing.
"But they will. Eventually. They always do." Watanabe closed the folder. "You have a daughter, don't you? Mai. She's twelve. She goes to Sakuragaoka Elementary."
Ishikawa's eyes flickered. Just for a moment.
"Nothing has to happen to her. Nothing will happen to her. But if you don't cooperate — if you force us to build a case without your testimony — your wife and daughter will be questioned. Their names will be in the news. Their faces will be on television."
"You can't do that." Ishikawa's voice was rough, like gravel.
"I can. And I will." Watanabe's voice was calm, almost gentle. "Unless you give me something. A name. A location. Something that ties your employer to the kidnapping."
Ishikawa stared at her. His jaw was tight, his hands were clenched.
"Protection," he said finally. "For my family. And immunity for me."
"Immunity isn't my decision. But protection — that I can arrange."
Ishikawa was silent for a long moment. Then he said, "His name is Akira Akiyama. He hired us through a middleman. We never met him directly."
"Do you have proof? Records? Messages?"
"The middleman's name is Tanaka. No first name — just Tanaka. He paid us in cash. But he used a phone. A burner. I kept the number."
Watanabe's pen moved across her notepad. "And the middleman — where can I find him?"
"I don't know. He always came to us. Always at night. Always alone."
Watanabe leaned back. "That's not enough."
"It's all I have."
"It's not enough to arrest Akiyama. It's not enough for a warrant. It's not even enough for a search."
Ishikawa's face went pale. "You promised —"
"I promised protection for your family. And I'll give it. But I can't promise immunity if you don't give me something I can use."
The room was silent. Ren watched through the mirror, his hands in his pockets, his heart pounding.
Then Ishikawa said, "There's something else. Something I didn't mention."
Watanabe leaned forward. "What?"
"The warehouse. Akiyama came there once. Three days before we took the woman. He wore a mask, but I saw his eyes. And he left something behind."
"What?"
"A briefcase. He was carrying it when he arrived. He wasn't carrying it when he left."
Watanabe's eyes narrowed. "Where's the briefcase now?"
"Locked in the office. Second floor. Behind the loose panel in the wall."
Watanabe stood up. She walked to the door and opened it. Ren stepped back from the mirror, but she wasn't looking at him — she was looking at the officers in the hallway.
"I need a team at the warehouse," she said. "Now."
---
The warehouse looked different in daylight.
Abandoned, mostly — broken windows, rusted fences, the kind of place where teenagers went to drink and homeless people went to sleep. But the office on the second floor was still there, the door still locked, the loose panel still hidden behind a stack of old boxes.
Ren stood outside the yellow tape, watching the forensic team work. Hikari was beside him, her hand in his.
"What do you think is in the briefcase?" she asked.
"I don't know. But my father wouldn't have left it unless it was important."
"Or unless he wanted us to find it."
Ren looked at her. "You think it's a trap?"
"I think your father is always planning something. Even when he's losing."
The forensic team emerged from the building. One of them was carrying a briefcase — black, scuffed, locked with a combination lock.
Detective Watanabe walked over to them. "We'll open it at the station. You can watch from the observation room."
Ren nodded. "Thank you."
"Don't thank me yet. It might be nothing."
"But it might be everything."
---
The station's observation room was even smaller than the one at the courthouse.
Ren stood at the window, looking down at the evidence room where Watanabe and her team were gathered around the briefcase. Hikari stood beside him, her shoulder pressed against his.
Takeshi was in the corner, his arms crossed, his eyes fixed on the same scene.
"They're opening it," Ren said.
The briefcase opened.
Inside were folders — thick, bulging, filled with papers. Watanabe pulled one out and started reading. Her face went pale.
"What is it?" Ren whispered, even though she couldn't hear him.
Watanabe looked up at the mirror — at him — and held up the folder.
On the cover, written in black marker: TACHIBANA FAMILY — ASSETS AND LIABILITIES.
Hikari's breath caught. "That's — that's about my family."
"Your father's company," Ren said. "Your father's arrest. Your mother's breakdown." His voice was cold. "My father was involved. Somehow."
Watanabe opened another folder. Then another. Each one had a name written on the cover — judges, lawyers, police officers, politicians. Names from the list Hikari's mother had given them. Names they had been trying to verify for weeks.
"He kept records," Ren said. "He kept evidence of his own crimes."
"Or his leverage," Takeshi said. "A man like your father doesn't keep records for the police. He keeps them for himself. To use when people try to betray him."
Ren watched as Watanabe pulled out a small notebook — leather-bound, worn, the pages filled with handwriting he recognized.
His father's handwriting.
"What does it say?" Hikari asked.
"I can't read it from here. But I'm going to find out."
---
Watanabe met them in the lobby an hour later.
Her face was grim, but her eyes were bright.
"The briefcase is a goldmine," she said. "Records of payments. Names of accomplices. Dates, times, locations. Your father wasn't just involved in the kidnapping — he was involved in everything. The trafficking network. The hospital conspiracy. The corruption in the courts."
Ren's heart pounded. "Is it enough to arrest him?"
"It's enough to arrest him and hold him without bail. It's enough to charge him with conspiracy to commit murder. It's enough to put him away for the rest of his life."
"Then do it."
Watanabe nodded. "I'm going to request a warrant now. We'll move as soon as we have it."
"How long?"
"Hours. Maybe less."
Ren looked at Hikari. She was smiling — a real smile, bright and warm.
"We did it," she said.
"We did it."
But even as he said it, Ren knew it wasn't over. The arrest was just the beginning. The trial would follow. The testimony. The appeals. The years of legal battles.
His father would fight. His father would lie. His father would do everything in his power to destroy them.
But they had the evidence. They had the witnesses. They had the truth.
And for the first time, Ren believed that was enough.
