The train journey back took just over five hours. Yuna sat in an empty car, staring at her phone.

  The message from the unknown number was still there:

  Find Dr. Takeshi Umino. If you can.

  If you can.

  Meaning: he's hidden. Or hiding. Or disappeared so thoroughly that finding him would require resources Yuna didn't have.

  At Nagoya Station during the transfer, she found a quiet corner café and opened her laptop.

  "Rose, I need everything you can find on Dr. Takeshi Umino after March 2021. Employment records, property purchases, social media, anything public."

  "Searching public databases... Results: zero. No employment records, no property transactions, no social media presence under that name after March 15, 2021."

  "He vanished completely?"

  "Or changed his identity. Name change records are sealed in Japan. However, I can search property registration records—those are public. Shall I search for recent property purchases in Mie Prefecture? Male, age 45-50, single-name registrations?"

  "Do it."

  Several minutes passed. Yuna sipped her coffee, watching commuters rush through the station.

  "Search complete," Rose announced. "I found 23 property purchases matching the demographic profile in Mie Prefecture between March and August 2021. Filtering for locations within reasonable distance of Wagu... Six candidates remain. Shall I display the list?"

  "Yes."

  The screen populated with addresses. Yuna scanned them. Five were in larger cities—Ise, Matsusaka. One was in Toba City.

  Takahashi Kenji, age 47. 3-15-8 Uramura-cho, Toba City. Detached single-family house. Purchase date: April 2021.

  Toba City. Forty minutes from Wagu. Forty minutes from Tidewater Facility.

  Close enough to watch. Far enough to hide.

  "Rose, can you find any other information about Takahashi Kenji?"

  "Searching... No employment records. No social media presence. No utility company listings—those are private. Property registration shows single-name ownership, no mortgage. Cash purchase."

  Cash purchase. Someone who didn't want a paper trail.

  Yuna stared at the list. Six possibilities. But Toba was the closest to Wagu. If Umino wanted to watch his son from a distance, that's where he'd be.

  Close enough to watch. Far enough to hide.

  Yuna closed her laptop. She couldn't approach any of these addresses directly—if one of them was Umino, showing up could put him in danger. Might put Shizuka in danger.

  She needed to be careful.

  Back in her apartment, Yuna spent two days planning her approach.

  She studied the six candidates. Five seemed unlikely—wrong locations, wrong profiles. But Takahashi Kenji in Toba... the timing matched. The location matched. The cash purchase suggested someone hiding.

  But she couldn't be certain. Not yet.

  On the evening of the second day, her phone buzzed. Text message. Unknown number—the same one from before.

  You're looking at six names. Takahashi Kenji in Toba is the one you want. He watches the facility every night from the cliffs. Confirmed.

  Yuna stared at the message. Someone inside HelixGen was watching her search. Guiding her. But why?

  She typed back: How do you know I'm searching? Who are you?

  Three dots appeared. Then disappeared. No response.

  But the confirmation was there. Takahashi Kenji. Toba City. That was Umino.

  Yuna pulled up the property records again. She couldn't just knock on his door and ask: "Are you secretly Dr. Umino, father of the human test subject I've been illegally investigating?"

  She needed confirmation first. Proof this was the right person. A way to make contact that wouldn't trigger HelixGen's surveillance.

  Yuna opened her laptop. "Rose, can you access any photos of Dr. Umino from before his disappearance?"

  "Searching academic databases... Found: author photo from published paper, 2018. Quality is low—90x90 pixels, compressed."

  The image appeared on the laptop screen. A man in his forties, dark hair graying at the temples, wire-rimmed glasses, tired smile. The photo was too small to show much detail, but Yuna memorized what she could.

  She needed to see Takahashi Kenji. Compare him to this image. Confirm identity before making contact.

  On the third day, Yuna took the train to Toba.

  Toba was a small coastal city, quieter than Wagu, built around fishing and pearl cultivation. The address—3-15-8 Uramura-cho—was in a residential area: modest houses, narrow streets, the smell of salt water in the air.

  From the station, she walked. Twenty minutes on foot through winding streets brought her to the neighborhood. She'd dressed casually—jeans, a jacket, sunglasses. Just another person out for a walk on a Monday afternoon.

  The house at 3-15-8 Uramura-cho was a small detached home. Single story, faded blue paint, a tiny garden with overgrown weeds—not an apartment building, but a standalone house with its own entrance. One car in the driveway—an old sedan, maybe fifteen years old.

  Someone lived here. But were they home?

  Yuna found a bench at a small park across the street. Pretended to read a book on her tablet. Waited.

  At 2:17 PM, the front door opened.

  A man emerged. Forties, dark hair, no glasses—but the face structure matched. Thinner than in the photo. More tired. But possibly the same person.

  He walked to his car, got in, drove away.

  Yuna stayed on the bench. He might come back soon. She'd wait.

  At 3:45 PM, the car returned. The man got out carrying grocery bags. Went inside.

  Yuna took photos with her phone. Sent them to Rose.

  "Rose, facial recognition. Compare these images to the 2018 photo of Dr. Umino."

  "Analyzing... Confidence level: 73%. Similar facial structure, but subject has lost approximately 8 kilograms body mass. Hair is shorter. Posture suggests chronic stress. Cannot confirm with certainty, but probability is high."

  73%. Not definitive, but promising.

  Yuna needed to get closer. Needed to hear his voice, maybe. Or see something that would confirm identity beyond doubt.

  But approaching him directly was still too risky.

  She spent the next three days observing Takahashi Kenji's patterns.

  Royal Road is the home of this novel. Visit there to read the original and support the author.

  He left the house at 9 AM each morning. Returned around 4 PM. Always alone. Always carrying groceries or other supplies. Never speaking to neighbors. Never receiving visitors.

  A man living in isolation. By choice or necessity.

  On the fourth day, Yuna followed him.

  He drove to a small convenience store, bought supplies—food, cleaning products, batteries. Then to a bookstore. Then to a coffee shop where he sat alone for an hour, reading a newspaper.

  Yuna watched from a distance. He looked... tired. Defeated. Like someone carrying a weight they couldn't put down.

  At 3:30 PM, he left the coffee shop and walked to a parking lot overlooking the harbor.

  Yuna followed on foot, staying fifty meters back.

  The man—Takahashi, or Umino, or whoever he was—stood at the edge of the lot, looking out at the ocean. His hands gripped the railing. His shoulders were tense.

  And he stayed there. Ten minutes. Fifteen. Just looking at the water.

  Yuna moved closer. Not confrontational. Just... walking along the harbor like any other person would.

  At thirty meters, she stopped. Pretended to look at the ocean too.

  The man didn't turn. Didn't acknowledge her presence.

  But after a moment, he spoke. Quietly. Not looking at her.

  "You've been following me for four days."

  Yuna's breath caught. "I—"

  "Three days at my house. One day trailing me through town. You're not very subtle." His voice was flat. Exhausted. "Whatever you're selling, I'm not interested. Whatever you want, I can't help you."

  "I'm not selling anything."

  "Then what do you want?"

  Yuna took a chance. "I want to know about your son."

  The man's hands tightened on the railing. For a long moment, he didn't move. Didn't speak.

  Then, very quietly: "I don't have a son."

  "You did. Shizuka Umino. Born April 2010. Enrolled in experimental telomerase treatment at age nine. You were Dr. Takeshi Umino. Researcher at ReGeneLab. You tried to pull him out. They stopped you."

  The man turned slowly. His eyes were red-rimmed. Tired beyond measure.

  "Who are you?"

  "My name is Yuna Shirasaki. I'm a researcher at ReGeneLab. Or I was. I found your son in the data. I've been trying to understand what happened."

  Umino—because it had to be him—stared at her. "You need to leave. Right now. If HelixGen knows you're talking to me—"

  "They're already watching me. They know I went to Tidewater. They know I saw Shizuka on the balcony."

  "Then you're already finished. They'll destroy your career. Bury you legally. Make sure you never work again." He turned back to the ocean. "Go home. Forget about my son. There's nothing you can do."

  "I don't want to forget. I want to understand." Yuna moved closer. Still keeping distance. "I saw him. For seven minutes. Standing on that balcony. His fingers were tapping—the monitoring rhythm. He looked... adapted. But also alone."

  Umino's jaw clenched. "He is alone. Because I put him there. Because I was desperate and stupid and I believed them when they said it would work."

  "It did work. He's alive."

  "He's not alive. He's maintained." Umino's voice cracked. "There's a difference. Being alive means you can laugh without risking death. Means you can smell the ocean without triggering a panic response. Means you can be a kid. Shizuka can't do any of that. I didn't save him. I just... extended how long he has to suffer."

  The wind off the harbor was cold. Somewhere, a seagull cried.

  "Do you see him?" Yuna asked quietly. "Do they let you visit?"

  "Once a month. Two hours. Supervised. We sit in a room with glass between us. He tells me about what he's reading. I tell him about my day. We pretend everything is normal." Umino wiped his eyes. "He's fourteen. He should be worried about school and friends. Instead, he's learning to control his own heart rate. And I did that to him."

  "You were trying to save his life."

  "I was trying to save myself from watching him die. There's a difference." He looked at Yuna. "What do you want from me? Absolution? I can't give it. Information? I don't have any."

  "What happened? How did you end up here, watching from a distance?"

  Umino was quiet for a long moment. Then: "February 2021. Shizuka had been in treatment for eleven months. The incident rate was still extremely high—forty, fifty per month. He was learning to adapt, but it was slow. Painful. And I saw what it was doing to him. The isolation. The constant monitoring. The fear."

  He gripped the railing harder. "I decided to take him out. Just for a weekend. Somewhere quiet, controlled. I thought if I could give him even a glimpse of normal life... So I went to the facility. Told them I was taking him home for family emergency. I had my car ready. I had a place prepared."

  "What stopped you?"

  "Shizuka." Umino's voice broke. "He was ten years old—almost eleven. I told him we were leaving. And he looked at me and said: 'Dad, I'll die if I go outside. You know I'll die.' And I said: 'We'll be careful. We'll manage it.' And he said..."

  Umino wiped his eyes. "'I want to live, Dad. Even like this. I want to live.'"

  The ocean stretched endless before them.

  "Security arrived five minutes later. They'd been watching. They took Shizuka back to his room. Then they took me to Legal." Umino laughed bitterly. "They gave me a choice: sign an NDA, accept a new identity, relocate within observation distance, and I could keep monthly visits. Or refuse, and I'd never see him again. And they'd make sure I never worked in research anywhere."

  "They blackmailed you."

  "They gave me the only option that kept me in Shizuka's life. So I signed. Changed my name. Moved here. And I've been watching ever since."

  "You watch it?"

  "Every night. From the cliffs. With binoculars. I see his room light come on at 8 PM. Go off at 10:30. I see him on the balcony sometimes. And I know he can't see me. Know I'm not allowed to contact him except during authorized visits. But I watch anyway." His voice was hollow. "It's all I can do."

  Yuna felt something twist in her chest. This man had been watching his son from a distance for four years. Unable to help. Unable to leave.

  "I want to understand what he needs," Yuna said. "Not what HelixGen needs. Not what the research needs. What Shizuka needs."

  "He needs to be free. But he can't be free. His body won't survive outside that facility." Umino's hands shook on the railing. "So what he needs is impossible. Just like everything else about this situation."

  "What if—"

  "There is no 'what if.' I've spent four years thinking through every possibility. I've consulted with doctors, lawyers, ethicists. There's no path out of this that doesn't end with my son dead. So the best I can do is make sure HelixGen keeps their promise to keep him alive. And that means I stay invisible. I don't make trouble. I don't interfere."

  "But you're here. Talking to me."

  "Because you already know everything. Because HelixGen already knows you're investigating. And because—" He stopped. Took a shaking breath. "Because I'm tired of being the only one who knows. The only one who carries this."

  They stood in silence. The ocean stretched before them, endless and indifferent.

  "Next month," Umino said finally. "I have a scheduled visit. First Wednesday. 2 PM. If you want to see him—really see him, not from three hundred meters away—I can try to bring you. As a colleague. Someone consulting on his treatment."

  "They'll never allow it."

  "They might." Umino's expression was grim. "Because I have leverage they don't want to lose. I still know things. I still have documentation they think was destroyed. And I've made it clear: if they want my continued cooperation—my silence—they need to show good faith."

  "They threatened to sue me for fifty million yen."

  "Of course they did. That's how they operate. Fear first. But you're still here. Still investigating. Which means the lawsuit is a threat, not a certainty." He looked at her. "They've been watching you since you accessed the Z-0 files. The question was never whether to stop you—they already did that with your suspension. The question is whether you're useful alive or buried. I'm convincing them you're useful."

  "Useful how?"

  "If I say you're reviewing behavioral adaptation protocols. If I say you're interested in helping develop training procedures for future subjects. HelixGen wants to scale this technology. They want to know how to teach others what Shizuka learned through necessity. If you can offer that knowledge..."

  "I don't have that knowledge."

  "Neither do they. But they don't know that." Umino pulled out his phone. "Give me your number. I'll contact you if I can arrange it. No promises. No guarantees. But maybe."

  Yuna gave him her number. He saved it without comment.

  "One condition," he said. "When you see Shizuka—if you see him—don't pity him. Don't treat him like a victim. He hates that. He's adapted. Evolved. Become something extraordinary. Whatever you think about the cost, don't diminish what he's achieved."

  "I won't."

  "And don't promise him anything. Don't tell him you'll help him escape or expose the truth or save him. Because you can't. All you'll do is give him false hope. And he's survived this long by accepting reality as it is."

  Umino turned to leave. Then paused.

  "My son is extraordinary. Remember that. Not because of what was done to him. Because of what he did with it. What he turned himself into. That's the only good thing in this entire nightmare."

  He walked away. Got in his car. Drove off.

  Yuna stood alone at the harbor railing, watching the ocean.

  Four years. Umino had been watching his son from a distance for four years. Carrying guilt and grief and the knowledge that there was no escape.

  And Shizuka—fourteen years old—was living with the same knowledge. Adapted. Extraordinary. Alone.

  Yuna pulled out her phone. No new messages. No calls.

  But her contact list now had one new entry:

  Takahashi K.

  A father's shadow. Living close enough to watch. Too far away to help.

  She walked back to Toba Station. The train home gave her time to think.

  That night, back in her apartment, Yuna couldn't sleep.

  She kept thinking about Umino's words: He needs to be free. But he can't be free.

  And Shizuka's adaptation. The way his incident frequency had decreased over four years. The way he'd learned to sense his own internal state before machines could.

  Maybe there was no path to freedom. Not the kind normal people had.

  But maybe there was a path to something else. To mastery. To control so complete that the facility became optional instead of necessary.

  Maybe Shizuka was already working toward that. Learning. Adapting. Evolving.

  I can feel it. I'm holding it small.

  Yuna opened her laptop and pulled up the incident logs again. Studied the progression. The pattern of improvement.

  And she began to wonder: what would happen if Shizuka's adaptation continued? What would he become in another four years? Another eight?

  Would he remain dependent on the facility forever?

  Or would he eventually outgrow the need?

  Her phone buzzed. Text message. Unknown number—but not the same one as before. A new unknown number.

  First Wednesday next month. 2 PM. Don't eat anything unusual that day. Don't wear perfume. Keep your voice calm and quiet. If you trigger an incident, the visit ends immediately and you never come back.

  - T.K.

  Takahashi Kenji. Umino.

  He'd gotten permission. Or he was going to try.

  Yuna would get to see Shizuka. Not from three hundred meters. Not through binoculars.

  Face to face.

  If she could survive the scrutiny. If she could prove she was useful to HelixGen. If she could keep Shizuka stable.

  And if she didn't get him killed.

  Discussion Question: Umino says Shizuka "needs to be free but can't be free." Is freedom always physical? Can someone be free while confined? Or is Umino right that there's no freedom in Shizuka's situation? Share your thoughts.
