Ikebukuro at night was a different world.
The neon signs burned brighter here—pink and blue and electric green, reflecting off the wet pavement like oil on water. Crowds of teenagers spilled out of arcades and karaoke bars, their laughter too loud, their clothes too bright. Ren walked through them like a ghost, his hands in his pockets, his eyes fixed on the address Takeshi had given him.
The building was in the back alleys, behind the main streets, where the lights were dimmer and the shadows were longer. A seven-story walk-up with peeling paint and a buzzer that didn't work. Ren pushed open the door and climbed the stairs.
The fourth floor. Room 403.
He knocked.
No answer.
He knocked again.
The door opened a crack. A single eye peered out—young, female, sharp.
"You're not Takeshi," the voice said.
"I'm Ren Akiyama. He sent me."
The eye studied him for a long moment. Then the door opened.
Akemi was younger than Ren expected. Maybe twenty. Maybe twenty-two. Her hair was dyed in shades of purple and blue, chopped short and messy. She wore an oversized hoodie and ripped jeans, and her bare feet were covered in colorful tattoos—circuit boards, maybe, or abstract patterns. Her apartment was a mess of computers, monitors, and tangled cables. The air smelled like instant ramen and burnt coffee.
"Close the door," she said. "And lock it."
Ren stepped inside. The door clicked shut behind him. Three locks. He counted.
Akemi sat down in front of a bank of monitors—six screens, each displaying a different stream of data. Code scrolled past too fast for Ren to read, but he recognized the patterns. She was running multiple searches simultaneously. Cross-referencing. Data mining.
"Takeshi said you're a hacker," Ren said.
"Takeshi says a lot of things." She didn't look away from the screens. "I prefer 'information architect.' But hacker works. What do you need?"
"A man. Kenji Takahashi. I need to find him."
Akemi's fingers paused on the keyboard. She turned to look at him.
"Kenji Takahashi. The guy from the news. The one connected to the trafficking network."
"Yes."
"He's been hiding for weeks. Police can't find him. Private investigators can't find him. And you think I can?"
"I think you're the best. Takeshi said so."
Akemi snorted. "Takeshi flatters me because I helped him once. That doesn't mean I'm a miracle worker."
"I'm not asking for a miracle. I'm asking for a location. A starting point. Anything."
She studied him for a long moment. Then she turned back to her screens.
"Sit down," she said. "This might take a while."

Ren sat on a stool that wobbled dangerously. He watched Akemi work.
She was fast. Faster than anyone he had ever seen. Her fingers flew across the keyboard, pulling up records, cross-referencing names, following digital trails that most people didn't know existed. Bank accounts. Phone records. CCTV footage from convenience stores and train stations. She had access to things that should have been impossible to access.
"How do you do this?" Ren asked.
"Talent. Practice. And a complete disregard for the law." She didn't look up. "Kenji is good at hiding. Better than most. He uses cash, burner phones, fake names. But he's not perfect."
"No one is."
"Exactly." She pulled up a map of Tokyo, overlaid with red dots. "These are his known locations over the past six months. His apartment. His office. His favorite restaurants. See the pattern?"
Ren leaned closer. The dots clustered in Shinjuku, Ginza, Roppongi. Wealthy neighborhoods. Safe neighborhoods. But there were outliers—small clusters in less obvious areas.
"Nakano," Ren said. "We found him there."
"Takeshi told me. But look closer." She zoomed in on the Nakano cluster. "He's been in that area before. Multiple times. Always the same few blocks. That's not random. That's a pattern."
"He has a safe house there. Maybe more than one."
"Maybe." Akemi pulled up another layer—property records, rental agreements, utility bills. "I'm cross-referencing the addresses with shell companies connected to Sakamoto Tetsuya. If there's a connection, I'll find it."
"How long?"
"A few hours. Maybe less." She finally looked at him. "You should go. Get some sleep. I'll call you when I have something."
"I don't sleep."
"Everyone sleeps."
"I don't."
Akemi raised an eyebrow. "Suit yourself. But don't touch anything."
She turned back to her screens. Ren sat on the wobbling stool and watched her work.
---
Three hours later, she found something.
"Got him," she said.
Ren stood up so fast the stool nearly tipped over.
"There's a building in Suginami. West Tokyo. Owned by a shell company connected to Sakamoto. Short-term rentals, cash only, no questions asked." She pulled up a satellite image. "Kenji's phone pinged near there two days ago. Not a call—just a location ping. He probably didn't even know it happened."
"Can you get me the exact address?"
"I can do better." She typed for a few seconds, then pulled up a floor plan. "Third floor. Apartment 302. Two bedrooms, one bathroom, back exit to the fire escape. No front-facing windows, so he can't be seen from the street."
Ren memorized the layout. "Is he there now?"
"I don't know. The phone hasn't pinged since yesterday. He might have turned it off. Or ditched it." She looked at him. "This is as close as I can get. The rest is up to you."
Ren pulled out his phone. "Send me the address. And the floor plan."
"Done." Akemi leaned back in her chair. "You know this is dangerous, right? Kenji isn't just hiding. He's waiting. For you. For Hikari. For someone to make a mistake."
"I know."
"And you're going anyway."
"Yes."
"Why?"
Ren looked at her. At her purple hair, her tattooed feet, her sharp eyes that had seen too much.
"Because she's alone," he said. "Because I promised to protect her. Because if I don't do this, no one will."
Akemi was quiet for a moment. Then she nodded.
"You're an idiot," she said.
"I know."
"But you're not wrong." She stood up and walked to a drawer in the corner. She pulled out a small device—black, rectangular, with a single button. "This is a GPS tracker. Military grade. Stick it on his car, his bag, whatever. It'll send his location to my server every thirty seconds."
Ren took the device. "Why are you helping me?"
"Because I hate people like Kenji. Because I've seen what they do to girls like Hikari." She smiled—a thin, hard smile. "And because Takeshi said you were worth the risk."
Ren put the tracker in his pocket. "Thank you."
"Don't thank me. Just don't get killed."

Ren walked out of Akemi's apartment at 2 AM.
The streets of Ikebukuro were quieter now—the crowds had dispersed, the arcades had closed, the neon signs still burned but the energy had faded. He walked to the station, bought a ticket, and took the train back to Kamata.
Takeshi was waiting at the apartment, his face etched with worry.
"You were gone for five hours."
"I found her."
"And?"
"She found Kenji. Or at least, she found where he might be." Ren showed him the address on his phone. "Suginami. Apartment 302. He was there two days ago."
Takeshi studied the address. "That's close. Too close. He's been moving around us this whole time."
"I know."
"We need to tell the police."
"We need proof first. Otherwise, they won't do anything."
Takeshi looked at him. "What are you planning?"
Ren didn't answer. He walked to the window and looked out at the river. The moon was full, reflected in the dark water.
"I'm going to Suginami tomorrow," he said. "To confirm he's there. To get proof. To put a tracker on his car if I can."
"Alone?"
"Alone is quieter. Less attention."
Takeshi was silent for a long moment. Then he said, "I'm coming with you. Not as backup—as a lookout. Someone needs to watch your back."
Ren turned around. "Fine. But we do this my way. No heroics. No guns unless absolutely necessary."
"Agreed."
They shook hands. It felt like a contract. Like a promise.
---
The next morning, Ren visited Hikari again.
The same group home. The same beige walls. The same social worker, Suzuki, watching from the corner. But this time, Hikari looked different. Lighter. Almost hopeful.
"I heard about the motion," she said. "To move me to a different home. Is it true?"
"It's filed. We're waiting for the judge to decide."
"And if she says yes?"
"Then you'll be somewhere safer. Somewhere Kenji can't reach you."
Hikari's eyes glistened. "And you? Where will you be?"
Ren hesitated. He couldn't tell her about Suginami. About the tracker. About the plan. Not yet. Not while she was being watched.
"I'll be where I always am," he said. "Looking for you. Thinking about you. Waiting for the day we can be together again."
"That sounds like a long time."
"It won't be."
She smiled—a small, fragile smile. "You always say that."
"Because it's always true."
The visit ended too soon. Ren walked out of the group home, his hands in his pockets, his heart heavy.
Takeshi was waiting in the car.
"Ready?" he asked.
"No," Ren said. "But let's go anyway."
They drove to Suginami.
---
The building was exactly as Akemi had described.
Three stories. Gray concrete. Narrow windows. A back alley that led to a fire escape. Ren stood across the street, pretending to look at his phone, while his eyes scanned the building.
Takeshi was in a coffee shop down the block, watching through the window.
At 11 AM, a car pulled into the alley.
A black sedan. Tinted windows. Expensive.
Ren's heart rate quickened.
The driver's door opened. A man stepped out—large, broad-shouldered, the same man from the Nakano building. The one with the scar. He walked to the back of the building and disappeared inside.
Ren waited.
Five minutes passed. Ten. Fifteen.
Then the door opened again. Another man emerged—taller, thinner, wearing a dark coat. He looked around, checked the alley, and then gestured to someone inside.
Kenji stepped out.
Ren's breath caught.
He looked different from the photographs. Thinner. Paler. His expensive suit was rumpled, his hair unkempt. He looked like a man who hadn't slept in days. A man who was running out of time.
But his eyes were the same. Sharp. Calculating. Dangerous.
Kenji walked to the sedan and got into the back seat. The driver—a third man, one Ren hadn't seen before—started the engine.
Ren pulled out the tracker Akemi had given him. Small. Black. Magnetic.
He had one chance.
The sedan pulled out of the alley and turned onto the main road. Ren stepped off the curb, walking toward the crosswalk, his path intersecting with the car's path.
As the sedan passed him, Ren reached out—casually, like he was adjusting his jacket—and pressed the tracker to the rear bumper.
It stuck.
The sedan drove on.
Ren walked to the coffee shop, his heart pounding, his hands steady.
"I did it," he said to Takeshi.
Takeshi nodded. "Now we wait."
They sat in the coffee shop, watching the tracker's signal on Ren's phone. The dot moved through Suginami, then onto the highway, heading west.
"Where's he going?" Takeshi asked.
"I don't know. But we'll find out."
The dot stopped twenty minutes later. In Chofu. Near the Tama River.
"He's there," Ren said. "He's not moving."
"That could be his location. Or he could have found the tracker."
"We'll know soon enough."
They finished their coffee, paid the bill, and walked to the car.
The hunt was still on.
And Ren was closer than ever.
