Yuna spent them preparing.
Not physically—she knew what Umino had said. No perfume. No unusual foods. Calm voice. She could manage that. The preparation she needed was deeper. She needed to understand who she was about to meet.
She needed to understand Shizuka.
But first, HelixGen needed to decide her fate.
Two days after meeting Umino at the harbor, Yuna received an email. The sender made her stomach drop: Reiko Tanaka, HelixGen Legal Department.
She opened it with shaking hands.

Reiko Tanaka
Senior Legal Counsel, HelixGen Corporation
Yuna read it three times.
They were buying her. Or burying her. The choice was hers.
She could refuse. Let them sue her. Lose everything. Never see Shizuka again.
Or she could accept. Become complicit. Help them scale a technology that turned children into living closed-loop systems.
But refusing wouldn't help Shizuka. Wouldn't change what had been done to him. Wouldn't give him freedom.
At least if she accepted, she could see him. Understand what he'd become. Maybe—maybe—find a way to help that didn't involve legal battles she couldn't win.
Yuna opened a reply window and typed two words:
I accept.
She hit send before she could change her mind.
Three hours later, her phone buzzed. Text from Takahashi K.:
Got permission. Listed you as behavioral adaptation consultant. You'll have 15 minutes, not 2 hours. Glass partition. Medical staff present. Any sign of distress and they end it immediately.
Fifteen minutes. Through glass. With observers.
Not ideal. But more than the seven minutes she'd had from three hundred meters away.
Yuna typed back: What do I need to know?
The response came an hour later:
Everything. And I can't type it. Meet me tomorrow. Same place. 3 PM.
The harbor parking lot was empty except for Umino's car when Yuna arrived. He stood at the same railing, looking at the same ocean. Like he'd never left.
"You came," he said without turning.
"Of course."
"HelixGen is watching you. They know we met. They know you're going to visit Shizuka. They're allowing it because they think you might be useful."
"Useful how?"
"They want to scale the technology. Teach others what Shizuka learned through necessity. If you can document his adaptation methods, his coping mechanisms, his self-regulation techniques—they can develop training protocols." Umino finally looked at her. "That's why they're letting you in. Not because they're kind. Because you might help them replicate him."
"And if I refuse to help them?"
"Then you don't get in. Simple as that." He pulled out a worn notebook from his jacket. "I've been documenting Shizuka's progression for four years. Everything I observe during visits. Everything the medical staff tells me. Everything I can see through binoculars. It's not complete. But it's what I have."
He handed her the notebook. The cover was soft from handling. The pages inside were filled with neat handwriting, dates, observations.
2021.08.14 - Visit day. Shizuka's heart rate baseline: 72 bpm.
Noticed finger tapping has become more rhythmic. Asked him about
it. He said: "It helps me know where I am." Meaning: helps him
monitor internal state. Tapping speed correlates with stress level.
2021.09.22 - Watched from cliffs. Saw him on balcony for 8 minutes.
Stood very still. Staff member approached at minute 6, said something.
Shizuka nodded but didn't move. Stayed until minute 8, then went
inside. Controlled exposure? Or his choice?
2021.11.03 - Visit day. Shizuka told me he's "getting better at
waiting." Asked what he meant. "When I feel something coming—like
my heart wants to speed up—I can wait. Just watch it. And sometimes
it goes away on its own." Ten years old. Describing interoceptive
meditation I've never seen documented in any literature.
Yuna read entry after entry. Four years of a father watching his son adapt. Learning. Evolving.
"This is incredible," she said.
"This is torture." Umino's voice was flat. "Reading it. Writing it. Knowing my son is developing abilities no human should need. And I caused it."
"You saved his life."
"I extended his suffering. There's a difference." He looked back at the ocean. "But he's alive. And he's... extraordinary. Whatever I think about the cost, I can't deny that."
Yuna turned pages. The entries grew more detailed over time. More technical. More precise.
2023.02.17 - Visit day. Discussed incident from last week (Feb 10).
Shizuka described it with clinical precision: "Started at 14:23.
Heard something—maybe a door closing too hard. Felt my heart jump
from 69 to 94. Knew I had about six seconds before it would hit
threshold. Did the breathing thing. Dropped to 87 within four seconds.
Safe." Twelve years old. Describing tachycardia prevention like a
routine task.
2023.07.08 - Watched from cliffs. Storm coming in. Saw staff evacuate
Shizuka from balcony. But he stopped at the door. Stood there for
maybe 15 seconds, facing the storm. Staff member seemed agitated.
Shizuka finally went inside. Asked about it during next visit. He
said: "I wanted to see if I could handle it. The wind, the sound,
the pressure change. I could. For 15 seconds." Testing his limits.
Deliberately.
"He's experimenting," Yuna said. "Pushing boundaries."
"He's trying to expand his cage." Umino took the notebook back, flipped to a recent entry. "Read this one. From three weeks ago."
2025.01.15 - Visit day. Shizuka asked me a question I couldn't answer:
"Dad, if I get good enough at this—at controlling everything—could
I leave? Could I live outside?" I didn't know what to say. Told him
I don't know. He said: "That's okay. I'll figure it out." Fourteen
years old. Planning his own escape through pure adaptation. I don't
know if that's hope or delusion.
Support the author by searching for the original publication of this novel.
Yuna's chest tightened. "What did you tell him?"
"The truth. I don't know if complete adaptation is possible. No one does. He's the only data point." Umino closed the notebook. "But he believes it is. And maybe that belief is keeping him alive more than the technology is."
They stood in silence. The ocean wind was cold. Gray clouds gathered on the horizon.
"When you meet him," Umino said quietly, "you need to understand something. Shizuka is polite. Articulate. He'll answer your questions. He'll seem calm. But that calmness is constant work. Every second, he's monitoring. Adjusting. Maintaining. It's like... imagine walking on a tightrope. Over a pit. Forever. That's what conversation is for him."
"Then maybe I shouldn't—"
"No. You should. Because isolation is killing him too. Just slower. He needs contact with the outside world. Needs to know people see him, understand him, care about what happens to him." Umino's hands gripped the railing. "I can't give him that. I'm his father. He needs someone else. Someone who chose to look for him. Someone who isn't trapped by guilt."
"I don't know if I can help."
"You can witness. That's enough." Umino pulled out his phone. "I'm sending you protocols. Things to avoid. Things that help. Study them. Because you get fifteen minutes. And if you waste them, you don't get more."
That evening, Yuna's phone pinged. A file from Takahashi K.: VISIT_PROTOCOLS.pdf.
She opened it. Twelve pages of detailed instructions:
ENVIRONMENTAL FACTORS:
- Room temperature maintained at 21-22°C (do not adjust)
- No perfumes, colognes, scented lotions
- No strong-smelling foods 24 hours before visit
- Clothing: neutral colors, soft fabrics (nothing synthetic that creates static)
BEHAVIORAL GUIDELINES:
- Speak at normal conversational volume (not whispered, not loud)
- No sudden movements
- No touching the glass partition
- No laughter (seriously)
- Keep facial expressions moderate
- Maintain consistent posture (shifting triggers his monitoring response)
CONVERSATION TOPICS - SAFE:
- Books he's reading
- General science/technology questions
- Philosophy, ethics (he enjoys these)
- Weather (surprisingly okay—he studies meteorology)
CONVERSATION TOPICS - AVOID:
- Direct questions about his medical condition
- Comparisons to "normal" life
- Expressions of pity or sympathy
- Discussion of his father's situation
- Any suggestion of "rescue" or "escape"
- Questions about what he "misses"
SIGNS OF DISTRESS:
- Finger tapping accelerates
- Breathing becomes deliberate (consciously controlled)
- Answers become shorter
- Eye contact decreases
- He asks to end the visit
IF DISTRESS OCCURS:
- Stop talking immediately
- Remain still
- Wait for medical staff to assess
- Do not apologize or explain
- Follow all staff instructions
At the bottom, a handwritten note:
He's not fragile. But his body thinks the world is dangerous. Treat him like someone navigating a minefield. Every word, every gesture, is a step that might trigger something. Be careful. Be present. Don't waste this. - T.K.
Yuna read the protocols three times. Memorized them. Printed them out and put them next to her bed.
She had nineteen days.
Over the following week, Yuna did something she hadn't done since graduate school: she studied.
Not research papers. Not data. She studied Shizuka.
She read Umino's notebook cover to cover. Four years of observations. Four years of a boy adapting to impossible conditions.
She pulled up every incident log Rose had cached. Studied the patterns. The triggers. The recovery times.
She found video fragments—corrupted files Rose had partially reconstructed. Most showed only monitoring equipment. But one, from two years ago, had audio:
[CORRUPTED VIDEO - AUDIO ONLY - 2023.04.22]
Dr. Matsuda: "Can you describe what you're feeling right now?"
Subject Z-0 (Shizuka): "Nervous. Heart rate is elevated. 78."
Matsuda: "Because of the camera?"
Shizuka: "Because I'm being asked to describe what I'm feeling while
I'm feeling it. It's recursive. Like watching myself watch myself."
Matsuda: "Is that difficult?"
Shizuka: [pause] "It's interesting. Most people don't have to do
this. They just... feel things. I have to feel things and observe
the feeling and regulate the observation and monitor the regulation.
It's like... being three people at once."
Matsuda: "Does it hurt?"
Shizuka: [longer pause] "I don't know how to answer that. It's just
what being alive is. For me."
Being three people at once.
Yuna listened to the audio fragment twenty times. Trying to understand what that meant. Trying to imagine what it felt like.
She couldn't.
But she could begin to see the shape of it. The constant self-observation. The recursive monitoring. The state of being permanently aware of your own awareness.
No wonder his incident rate had decreased. He wasn't just controlling his body. He'd learned to exist in a state of perpetual meta-cognition. Watching himself watch himself. Adjusting in real-time.
It was extraordinary.
It was also profoundly lonely.
Twelve days before the visit, Yuna received an email from HelixGen Legal:

Reiko Tanaka HelixGen Legal Department
Yuna stared at the email. It was real. In twelve days, she'd meet Shizuka Umino.
If she didn't mess it up. If she didn't trigger an incident. If she could navigate fifteen minutes of conversation without causing harm.
No pressure.
One week before the visit, Yuna practiced.
She set a timer for fifteen minutes. Sat in a chair in her apartment. Tried to maintain neutral posture, moderate expression, calm breathing.
"Rose, monitor my speech patterns. Flag anything that could be interpreted as emotionally intense."
"Acknowledged. Beginning analysis."
It was harder than she expected.
Fifteen minutes felt simultaneously too long and too short. Long enough to say something stupid. Short enough that every word mattered.
She practiced questions:
"What are you reading?" (Safe. Documented interest.)
"How do you decide when to go to the balcony?"
"Voice analysis: question contains implicit criticism. Likely to trigger defensive response," Rose interrupted.
Yuna sighed. "Right. Bad question. Next one."
"Do you enjoy meteorology?" (Safe. He studies weather patterns.)
"Do you ever wish—"
"Stop. Incomplete question structure suggesting emotional topic. High risk."
"I know, I know." Yuna rubbed her face. "Rose, this is impossible. How do I talk to someone where every word is a potential trigger?"
"By being present rather than perfect. Your concern for his wellbeing is evident in your preparation. That authenticity may matter more than flawless execution."
Yuna looked at her laptop screen. "Since when do you give emotional advice?"
"Since you've spent nineteen days preparing for a fifteen-minute conversation. The data suggests you care. That will communicate regardless of your word choice."
After three more practice sessions, Yuna gave up scripting. She couldn't prepare for this. She could only try not to cause harm.
Three days before the visit, Umino called her.
"Second thoughts?" he asked.
"Constantly."
"Good. That means you're taking this seriously." A pause. "Shizuka knows you're coming. I told him last visit. He asked why you wanted to meet him."
"What did you tell him?"
"That you're studying adaptation. That you want to understand how he does what he does. He seemed... interested. Said: 'Maybe she can tell other people. So they know what it's like.'"
Yuna's throat tightened. "He wants people to know?"
"He wants people to understand. There's a difference. He's not looking for pity. He's looking for recognition. For someone to see what he's become and acknowledge it." Umino's voice was quiet. "Don't disappoint him."
"I'll try not to."
"One more thing. Shizuka will probably test you."
"Test me how?"
"He does it with everyone new. He'll say something uncomfortable. Something true but difficult. Something that makes people react. He watches their response. Measures how honest they're willing to be."
"What should I do?"
"Be honest. He can tell when people lie. Or when they soften truth to make it palatable. He's spent four years learning to read physiological signals. He'll know if you're being authentic."
"No pressure," Yuna repeated.
Umino almost laughed. "You'll do fine. You found him. You tracked me down. You didn't give up when you should have. That's what he needs to see. Someone who cares enough to keep trying."
The night before the visit, Yuna couldn't sleep.
She lay in bed, staring at the ceiling, running through scenarios.
What if she triggered an incident?
What if fifteen minutes wasn't enough?
What if she said something that hurt him?
What if he hated her?
At 3 AM, she gave up on sleep and made tea. Sat at her kitchen table with Umino's notebook open in front of her.
She read the last entry. From five days ago:
2025.01.29 - Visit day. Told Shizuka about Dr. Shirasaki's upcoming
visit. He was quiet for a moment. Then: "Does she know what she's
looking at? Or does she just see a medical case?" I told him: she
sees you. He said: "Good. I'm tired of being invisible." Then he
smiled. First genuine smile I've seen in months. Maybe years.
I'm tired of being invisible.
Yuna closed the notebook.
Tomorrow, she'd make sure Shizuka Umino was seen.
Whatever happened, whatever she said, whatever consequences followed—she'd make sure he knew someone had looked and found him extraordinary.
Not because of what was done to him.
Because of what he'd become despite it.
- KAZUYA OKAMOTO
Discussion Question: Shizuka said "I'm tired of being invisible." What does visibility mean for someone in his situation? Is being seen enough? Or does he need something more? Share your thoughts.
