Takeshi left before noon.
He didn't say where he was going—something about "old contacts" and "people who owe me favors"—but Ren didn't need to be told. He was going to look for Lee Mina. The woman who had escaped from Sakamoto's network. The woman who had seen what Kenji really was.
"Stay inside," Takeshi said at the door. His hand rested on the gun in his jacket pocket—not because he was threatening anyone, but because that was where his hand always rested now. "Don't open the door for anyone. Don't answer calls from numbers you don't know. If something happens, there's a safe room in the back of the closet. The code is 0712."
"Your birthday?" Hikari asked.
"My sister's." Takeshi's jaw tightened. "She would have been thirty-four this year."
He left.
The door clicked shut. Three locks. Ren counted them. Deadbolt, chain, and a sliding bar that had been installed recently—the screws still shiny, the metal still bright. Takeshi had been preparing for something. Maybe for Kenji. Maybe for someone worse.
"What do we do now?" Hikari asked.
"We wait."
"For how long?"
"I don't know."
She walked to the window and looked out at the river. The morning fog had burned off, replaced by a pale winter sun that didn't provide any warmth. A woman walked her dog along the embankment. A child rode a bicycle, too fast, wobbling. Normal life. The kind of life that Ren had never really had.
"I hate waiting," Hikari said.
"I know."
"I hate feeling useless. Like all I can do is sit here and hope that someone else fixes my problems."
"You're not useless." Ren sat down on the couch—Takeshi's couch, old and lumpy, covered in a blanket that smelled like cigarettes. "You're the reason any of this is happening. Without you, Kenji wouldn't be scared. Without you, Kobayashi wouldn't have taken the case. Without you, Takeshi wouldn't have found us."
Hikari turned around. "Kenji isn't scared of me. He's scared of you."
"Kenji doesn't know me. He knows rumors. Old news. A reputation I left behind three years ago." Ren leaned his head back against the couch. "He's scared of what I represent. A variable he can't control. A person who doesn't want his money."
"And that's enough? Being a variable?"
"For now." Ren closed his eyes. "Eventually, we'll need more."

The afternoon passed slowly.
Hikari found a book on Takeshi's shelf—a mystery novel with a cracked spine—and read it on the balcony, wrapped in a blanket. Ren sat at the kitchen table with his phone, researching. Sakamoto Tetsuya. Lee Mina. Human trafficking networks in the Kanto region. Every article made him angrier. Every name he found—victims, mostly, but also perpetrators who had never been charged—made his hands shake.
At 4 PM, his phone rang.
Unknown number.
He almost didn't answer. But something—instinct, paranoia, the same voice that had kept him alive for three years—told him to pick up.
"Akiyama-kun." Kenji's voice. Smooth. Warm. Like honey poured over broken glass. "I was starting to think you'd changed your number."
"I'm considering it."
"Don't. I'd just find the new one. I'm very good at finding things. And people." A pause. "Speaking of which, I heard you moved. The Kamata neighborhood. By the river. Charming. Very... working class."
Ren's blood went cold. Kenji knew where they were. Of course he knew. Takeshi had said his apartment was safe, but safe was relative. Safe meant "harder to find," not "impossible."
"What do you want, Kenji?"
"I want to make you an offer. A real one. Not the nonsense I offered before—doubling her rent, that was insulting. I see that now. You're not the kind of person who can be bought with money."
"I can't be bought at all."
"Everyone can be bought, Akiyama-kun. The trick is finding the right price." Kenji's voice dropped, became intimate, conspiratorial. "For you, I think the price is information. Specifically, information about your mother."
Ren's grip tightened on the phone.
"I know what happened to her, Ren. Not just the cancer. The real story. The reason your father stopped paying for her treatment. The reason she died alone in a hospital room while you were on television, smiling for the cameras, pretending everything was fine."
"You're lying."
"I'm not. I have documents. Medical records. Financial statements. Your father's signature on a form that redirected her treatment funds to a different account." Kenji paused. "I'll give them to you. All of them. No strings attached. In exchange, you convince Hikari to come home with me."
Ren said nothing. His mind was racing, calculating, trying to find the flaw in Kenji's logic. But there was no flaw. Kenji had found the one thing Ren couldn't ignore.
His mother.
"Why do you want her so badly?" Ren asked. His voice was steady, but it cost him everything. "She's not worth anything. Her family's money is gone. Her name is ruined. What do you gain by controlling her?"
"Control is its own reward, Akiyama-kun. You of all people should understand that. You've spent three years controlling your environment—controlling how people see you, what they expect from you, how much they can hurt you. I'm the same. I control things. It's what I do."
"And if I refuse?"
"Then I'll get her anyway. Through the courts. Through the police. Through whatever means necessary. But it will be messy. People will get hurt. You might even get hurt." Kenji's voice hardened. "You're smart, Ren. Smarter than most adults. So be smart about this. Give me what I want, and I'll give you what you want. A fair trade."
Ren ended the call.
His hands were shaking. His heart was pounding. His vision had narrowed to a tunnel—the phone in his hand, the wall in front of him, the memory of his mother's face.
Don't cry, Ren. Mommy is fine. Mommy is just tired.
You're not fine. You're dying.
Everyone dies, sweetheart. The question is whether you live first.
Hikari appeared in the doorway. She must have heard his voice, or maybe she had just sensed that something was wrong. She was good at that.
"Who was that?"
"Kenji."
Her face went pale. "What did he want?"
"To make a deal." Ren looked up at her. His eyes were dark, empty, the eyes of a boy who had stopped believing in happy endings a long time ago. "He has information about my mother. Medical records. Proof that my father stopped paying for her treatment. He'll give them to me if I convince you to go with him."
Hikari walked across the room. She knelt in front of him, took his hands in hers, and looked into his eyes.
"Are you going to take the deal?"
"No."
"Why not?"
"Because your life isn't worth a stack of papers." His voice cracked. "Because my mother is dead, and you're alive. Because I couldn't save her, but I can save you."
Hikari's eyes filled with tears. She didn't wipe them away. She let them fall.
"You're a good person, Ren Akiyama."
"I'm not."
"You are. You're just broken. Like me." She leaned forward and pressed her forehead against his. "Broken people can still be good. They just have to try harder."
They stayed like that for a long time. Forehead to forehead. Hands clasped. Breathing the same air.
When Ren finally pulled away, his face was different. Harder. More certain.
"I'm going to destroy him," he said. "Not for me. For you. For Tanaka Yui. For Lee Mina. For every person he's ever hurt."
"Then let's destroy him together."

That night, Takeshi returned.
He looked exhausted—dark circles under his eyes, his jacket rumpled, his hands stained with what looked like coffee and something darker. But he was smiling. A real smile. The kind that reached his eyes.
"I found her," he said.
Ren stood up from the couch. "Lee Mina?"
"Lee Mina." Takeshi walked to the kitchen and poured himself a glass of water. He drank it in one long gulp, then set the glass down. "She's living in Chiba. Small apartment. Works at a laundromat. Uses a different name. Different hair. Different everything."
"Did you talk to her?"
"No. She saw me coming and ran. I followed her for six blocks before I lost her." Takeshi's smile didn't waver. "But I left a note. Told her who I was. Told her about Kenji. Told her about Hikari."
"And?" Hikari leaned forward.
"And she called me two hours ago. She wants to meet. Tomorrow. At a place she chooses." Takeshi looked at Ren. "She wants you there too. Both of you."
"Why us?" Ren asked.
"Because she wants to see if you're real. If Hikari is real. If this is another trap or if it's actually a chance to do something." Takeshi's expression sobered. "She's been burned before. By cops. By journalists. By people who promised to help and then disappeared when things got dangerous."
"We're not going to disappear," Hikari said.
"I know that. You know that. But she doesn't." Takeshi pulled out a chair and sat down heavily. "Tomorrow, you have to convince her. Not with words. With... whatever it is that made me believe in you."
Ren looked at Hikari. Hikari looked at Ren.
"We'll be ready," Ren said.

The next morning, they took a train to Chiba.
Takeshi sat across from them, his eyes scanning the carriage, his hand never far from his pocket. Hikari sat by the window, watching the city turn into suburbs turn into something that wasn't quite either. Ren sat beside her, his mind running through scenarios, contingencies, lies he could tell and truths he could reveal.
The meeting place was a small park near the coast. Empty this time of year—too cold for families, too far for tourists. The wind blew off the water, sharp and salty, cutting through their jackets like a knife.
A woman sat on a bench near the edge of the park.
She was small. Smaller than Ren expected. Her hair was short and dyed brown, but the roots showed black. She wore a heavy coat that was too big for her, like she had borrowed it from someone larger. Her hands were buried in her pockets. Her eyes—dark, wary, watching—followed them as they approached.
"Lee Mina?" Takeshi said.
The woman nodded. "You're the investigator."
"I am. These are the kids I told you about. Ren Akiyama and Hikari Tachibana."
Mina looked at them. Her gaze was sharp, assessing. She had the kind of eyes that had seen too much—the same eyes that Ren saw in the mirror every morning.
"You're young," she said.
"So are you," Hikari replied. "You're only twenty-four."
Mina's expression flickered. "I feel a hundred."
She gestured to the bench. There was room for two. Ren and Hikari sat. Takeshi stood a few meters away, giving them space but staying close enough to intervene if something went wrong.
Mina looked at Hikari first. "Your stepbrother. Kenji. What did he do to you?"
"He tried to control me. To own me. To use me as a bargaining chip." Hikari's voice was steady. "He broke into our apartment. He sent men to threaten us. He's using the court system to force me to live with him."
Mina nodded slowly. "That's how it starts. Control. Then isolation. Then... worse." She looked at Ren. "And you? Why are you involved? You're not family. You're not getting paid."
"No," Ren said. "I'm not."
"So why?"
Ren was quiet for a moment. The wind blew. A crow cawed somewhere in the distance.
"Because she asked me to help her," he said. "And because no one helped me when I asked."
Mina stared at him. For a long time, she didn't speak. Then she reached into her coat and pulled out a folded piece of paper. She handed it to Ren.
"It's a list," she said. "Names. Dates. Locations. Everything I remember about Sakamoto's network. Everything I remember about Kenji's role in it."
Ren unfolded the paper. The handwriting was small, cramped, like she had tried to fit as much as possible onto a single page. Dozens of names. Some were victims. Some were perpetrators. Some were places—warehouses, apartments, buildings that looked normal from the outside.
"This is..." Ren looked up at her. "This is enough to put him away for life."
"I know." Mina's voice was barely a whisper. "I've been carrying this list for three years. Waiting for someone to give it to. Someone who wouldn't use it and then forget about me."
"Why us?"
"Because you're young. Because you're fighting for each other. Because you haven't learned yet that the world doesn't care." She smiled—a sad, broken smile. "Maybe that's naive. But I'd rather be naive than dead inside."
Ren folded the paper carefully and put it in his pocket.
"Thank you," he said.
"Don't thank me. Just make sure he pays." Mina stood up. "I have to go. If they find out I talked to you—"
"They won't," Takeshi said. "I'll make sure of it."
Mina nodded. She looked at Hikari one last time. "Take care of each other. The world is hard. But it's easier when you're not alone."
She walked away. Her small figure disappeared into the trees, and then she was gone.
Ren sat on the bench, the list burning a hole in his pocket.
"We have it," he said. "We have everything we need."
Hikari took his hand. "Now we finish it."
Takeshi walked over and stood in front of them, his shadow falling across the bench.
"Kobayashi is waiting at her office," he said. "Let's go."
They walked back to the station. The wind was cold. The sky was gray. But for the first time in a long time, Ren felt something that might have been hope.
Real hope. Not the dangerous kind. The kind that came from knowing you had done everything you could.
