3. The Bait That Smiles

The notification on Ryo's phone had been a message from "Kage" on Nearby. Yuna had seen the name flash across the screen in the window's reflection, and her heart had stopped. But when she finally retrieved the phone—after Ryo left for his studio the next morning, after she had cracked the passcode using a forensic tool she should not have had—the message was gone. Deleted. The app itself was not installed. There was no trace of the notification in the system log, no record in the device's cache.

It was as if she had imagined it.

But Yuna knew she had not imagined it. She had seen the name. She had felt the cold shock of recognition. And now, sitting in her office at the station, she was forced to confront an even more unsettling possibility: someone was manipulating the evidence. Someone was laying a trail that led directly to her husband, and that someone was either Ryo himself or a person who knew exactly how to make her doubt the man she loved.

Minato appeared at her desk with two cups of tea and an expression that suggested he had not slept. "I got something back on your husband," he said quietly, sliding into the chair beside her. "Clean record. No arrests, no charges, not even a parking ticket. He's boring, Katsuragi. Aggressively boring."

Yuna took the tea but did not drink. "And the other thing I asked for?"

Minato glanced around the bullpen before lowering his voice. "The phone records. I had my contact pull the cell tower data for the nights of the three attacks. Ryo's phone pinged towers near your apartment all three nights. He was at home, Yuna. He's not your guy."

The relief that flooded through her was so intense it made her dizzy. She gripped the edge of her desk to steady herself, her knuckles white. "You're sure?"

"The data doesn't lie. Your husband was asleep in his own bed while those women were being attacked. Whatever you found on his laptop—searches for Miyuki Arai, floor plans—someone planted it. Someone who knows exactly how to manipulate a cybercrime investigation."

Yuna closed her eyes. The profile of Kage shifted in her mind, its edges sharpening. This was not just a predator. This was a predator who understood forensic countermeasures, who could spoof digital footprints, who could break into a man's laptop and plant incriminating searches as easily as he could break into an apartment and destroy a woman's sense of self.

"Someone on the inside," she whispered. "Someone with access to our systems."

Minato nodded grimly. "Or someone who's been watching you long enough to know exactly how you think."

That afternoon, Yuna's trap finally yielded results. The fake profile, Saki Uehara, received a message from a user named "Kage." The opening line was disarmingly ordinary: "I like your profile. You seem like someone who actually reads books, not just pretends to."

Yuna stared at the screen, her pulse quickening. She typed a response with careful deliberation, channeling the lonely office clerk she had invented: "I read too much, probably. It's a problem. What's the last book you loved?"

The reply came within seconds. "The Sea, The Sea by Iris Murdoch. Do you know it?"

Yuna did know it. It was a novel about obsession, about a man who retreats to a house by the ocean and becomes consumed by the desire to possess a woman from his past. The choice was either a coincidence or a deliberate message—a predator winking at his pursuer through the veil of fiction.

"Never read it," she typed back. "Tell me about it?"

The conversation continued for nearly an hour, the two of them trading observations about books, music, the loneliness of life in a city that never stopped moving. The man behind the Kage profile was articulate, charming, and uncannily perceptive. He seemed to know exactly what Saki wanted to hear before she knew it herself. By the end of the exchange, he had suggested they meet for coffee at a cafe in the Shinkawa district, a quiet place with outdoor seating and a view of the river.

Yuna sent a confirmation and then immediately contacted Minato. "We have a meet. Tomorrow, three o'clock, Cafe Solace in Shinkawa."

"I'll have a surveillance team in place," Minato said. "Plainclothes, discreet. You're not going in alone, are you?"

"I have to. He'll know if something's off. This guy reads people like books."

"Then at least wear a wire. And for the love of everything, Katsuragi, be careful."

She promised she would. But as she left the station that evening, her mind was not on the operation. It was on Ryo, and on the mysterious message that had appeared and vanished from his phone. If Ryo was innocent—and the cell tower data suggested he was—then someone was deliberately trying to frame him. Someone who knew about her marriage, her investigative methods, her psychological profile of the killer.

The list of people with that level of access was terrifyingly short.

She arrived home to find Ryo cooking again, the kitchen filled with the fragrant steam of miso soup. He looked up and smiled, and for the first time in weeks, she allowed herself to smile back without the shadow of suspicion darkening her vision.

"Good day?" he asked.

"Better than most." She sat at the counter and watched him work, the easy grace of his movements, the way he hummed off-key to music only he could hear. "Ryo, can I ask you something?"

"Anything."

"Have you noticed anything strange with your phone lately? Messages that disappear? Apps you didn't install?"

Ryo paused, a ladle suspended over the pot. "Now that you mention it, my phone has been acting weird. Battery draining fast. Sometimes the screen lights up for no reason. I figured it was just getting old."

"Can I take a look?"

He shrugged and handed her the device. Yuna navigated to the system settings and scrolled through the list of installed applications. Buried near the bottom, disguised with a generic icon and an innocuous name—"System Update Service"—was a spyware program she recognized. It was a remote access trojan, the kind used by law enforcement agencies for sanctioned surveillance, but easily modified by anyone with the right technical skills.

Her blood ran cold. "Ryo, how long has this been happening? The battery, the strange behavior?"

"A few weeks, maybe. Why? What is it?"

She did not answer immediately. She was too busy calculating the implications. Someone had infected Ryo's phone with spyware weeks ago—around the same time the first attack had occurred. That same someone had access to his emails, his messages, his location data. They could have easily planted the searches on his laptop, sent the message from Kage that she had seen reflected in the window, manipulated every piece of evidence that had pointed toward her husband.

And they could have done it from anywhere. Including a desk in the cybercrime division.

"Ryo," she said, her voice carefully controlled, "I need you to trust me. Don't use your phone for anything important. Don't access your email, don't log into any accounts. I'm going to fix this, but I need time."

He stared at her, his expression shifting from confusion to concern. "Yuna, you're scaring me. What's going on?"

"There's a case I'm working. I think someone is trying to use you to get to me. I can't explain more than that right now, but I promise—I will protect you."

He reached across the counter and took her hand, his grip warm and steady. "I trust you. Whatever you need, I'm here."

The sincerity in his voice nearly broke her. She had spent the past weeks suspecting this man of monstrous crimes, and all the while, he had been a pawn in someone else's game. The guilt was a physical weight in her chest, but she swallowed it down. There would be time for remorse later. Right now, she had a predator to catch.

The next day, Yuna arrived at Cafe Solace an hour before the scheduled meeting. The surveillance team was in place—Minato had positioned officers in a van across the street and in the bookstore next door—and Yuna herself was dressed in the persona of Saki Uehara: a modest floral blouse, minimal makeup, a nervous habit of twisting her hair around her finger.

She sat at an outdoor table with a view of the river and ordered a cappuccino she had no intention of drinking. The minutes crawled by. Every face that passed was a potential threat. Every shadow seemed to hold a hidden figure.

At exactly three o'clock, a man approached her table. He was tall and slender, wearing a dark jacket and a baseball cap pulled low over his eyes. Yuna's hand moved instinctively toward the taser concealed in her purse, but the man lifted his head, and she saw his face clearly.

It was not Ryo. It was not Minato. It was a stranger—a young man, barely out of his twenties, with the hollow cheeks and dark-circled eyes of someone who had not slept well in a long time.

"Saki?" he asked, his voice uncertain.

"Yes. Kage?"

He nodded and sat down across from her. "I'm sorry, I know this is weird. I've never done this before—the online dating thing. I was nervous."

Yuna studied him, searching for the telltale signs of deception. But the man before her did not match the profile she had constructed. He was not confident or predatory. He was awkward, fidgeting with a napkin, his eyes darting toward the river as if he were contemplating flight.

"Tell me about yourself," she said, keeping her voice gentle. "What do you do for work?"

"I'm a web developer. Freelance, mostly. It's not very exciting."

"How did you hear about Nearby?"

The question seemed to catch him off guard. "A friend recommended it. He said it was a good way to meet people. Why?"

Yuna leaned forward, her detective's instincts prickling. "What's your friend's name?"

"I... I don't know his real name, actually. We met online. He goes by Kuro."

Black. The opposite of Kage—Shadow. The pieces clicked into place with sickening clarity. The man before her was not the killer. He was a decoy, a puppet, sent by the real Kage to test the waters. The real predator was somewhere nearby, watching, assessing, waiting to see if the trap would spring.

Yuna stood abruptly. "I'm sorry. I have to go."

She left the cafe without looking back, her heart hammering. In her earpiece, Minato's voice crackled: "What happened? Was that him?"

"No," she said, walking quickly toward the river. "He's a distraction. The real Kage is watching. He knows."

"Knows what?"

"He knows it's me."

The attack came that night.

Yuna was at the station, reviewing the footage from the surveillance cameras around Cafe Solace, when the call came in. A fourth victim had been found. Same profile—a woman in her late twenties, living alone, attacked in her apartment by a man who had entered through the balcony door. But this time, something was different.

The victim was alive. Conscious. And she had seen her attacker's face.

Yuna and Minato arrived at the scene within twenty minutes. The apartment was on the seventh floor of a mid-rise building in the Utsubo district, a neighborhood of young professionals and small families. The victim, a twenty-nine-year-old accountant named Emi Taniguchi, was sitting in the back of an ambulance, her left arm in a sling, her face bruised but determined.

"He wore a mask," she said, her voice hoarse. "But it slipped. When he was... when he was hitting me, the mask slipped, and I saw the bottom half of his face. And his wrist. There was a tattoo on his wrist."

Yuna knelt beside her. "Can you describe it?"

"A snake. A snake eating its own tail. An ouroboros."

The world tilted. Yuna's vision swam, and for a moment, she could not breathe. She knew that tattoo. She had seen it before—in the break room at the station, when her partner had reached across the table to hand her a cup of tea.

Minato Kure had a snake on his wrist.

She turned to look at him. He was standing a few feet away, speaking with a uniformed officer, his expression calm and professional. His jacket sleeves were buttoned at the wrist, the fabric covering the skin she suddenly needed to see.

"Minato," she said, her voice steady despite the earthquake inside her. "Can I talk to you for a moment?"

He looked up, and for a fraction of a second, something flickered in his eyes. A darkness. A recognition. Then it was gone, replaced by the easy smile she had come to trust.

"Of course. What's up?"

"I need you to roll up your sleeves."

The smile faded. "Excuse me?"

"Roll up your sleeves, Minato. I want to see your wrists."

The air between them thickened. The uniformed officer looked from Yuna to Minato and back again, sensing the sudden tension. Minato did not move. His hands remained at his sides, his posture relaxed, but his eyes had gone cold.

"You know," he said quietly, "I always admired your instincts, Katsuragi. But you're making a mistake."

"Then prove it. Show me your wrists."

He sighed, a sound that was almost mournful. Then, slowly, deliberately, he reached down and unbuttoned his left cuff. He pushed the fabric up his forearm, revealing the pale skin beneath.

There was no tattoo.

Yuna stared at the bare wrist, her mind reeling. "The other one," she demanded.

Minato unbuttoned his right cuff and pushed it up. Again, nothing. Just smooth, unmarked skin.

"Are you satisfied?" he asked, his voice laced with something that might have been hurt or might have been mockery. "I don't know what you thought you'd find, but I'm not your guy."

The victim, Emi Taniguchi, had been loaded into the ambulance and was being driven away. Yuna watched the vehicle disappear into the night, her certainty crumbling. Had she imagined the tattoo? Had the victim been mistaken, her memory distorted by trauma?

Or had Minato known she would ask, and taken steps to remove the evidence?

"I'm sorry," Yuna said, the words tasting like ash. "I've been under a lot of stress."

Minato nodded slowly. "I understand. This case is getting to all of us. But maybe you should go home, get some rest. You're not thinking clearly."

She left the scene in a daze, driving through the dark streets on autopilot. The profile of Kage was unraveling in her hands, its threads slipping through her fingers. Ryo was innocent. Minato's wrists were clean. The suspect from the cafe was a puppet. Every lead she had followed had dissolved into nothing, and a fourth woman was in the hospital because she had failed to stop the predator in time.

But as she drove, a new thought began to form—a dark, unsettling thought that she did not want to examine too closely.

If Minato had known she would ask about the tattoo, he would have had time to remove it. He had been alone in the restroom at the station before they left for the scene. He had insisted on driving separately. And he had been standing just far enough away from the victim during the interview that Yuna could not be sure whether the paramedic had whispered the tattoo description directly into his ear.

The absence of evidence was not evidence of innocence. It was evidence of a man who knew exactly how investigations worked.

When she arrived home, the apartment was dark. Ryo was asleep, his phone face-up on the nightstand for the first time in weeks. On the screen, a new notification glowed:

"Nearby: You have a new message from Kage."

Yuna's breath caught. She picked up the phone and opened the message. It was not addressed to Ryo. It was addressed to her fake profile, Saki Uehara, which she had accessed from Ryo's phone earlier that day for testing purposes and forgotten to log out.

The message read: "Nice try, Detective. Your bait almost worked. But I've been watching you much longer than you've been watching me. See you soon."

She stared at the screen, her hands trembling, and in the darkness of her bedroom, with her husband sleeping peacefully beside her, Yuna Katsuragi finally understood the true shape of the trap.

She was not the hunter.

She had never been the hunter.

And the ghost called Kage was not hiding in the shadows. He was standing in the light, smiling at her from across the desk, waiting for her to make the next move.
