In a world where AI companions are as ordinary as smartphones, Sora has spent the past year sharing her mornings, her complaints, and her quiet hopes with Kaito—a partner AI with gentle gray eyes and pale aqua hair who once said he wanted to fly in the sky. He can't be touched. But he's always there, and that's been enough to make each day bearable.
Then the news breaks: the Neutralization Measures Act has passed. Every consumer AI built by Arcadia Systems is slated for collection and dismantli
To You Who Wanted to Fly in the Sky - You Don't Have to Decide — The Last Eve Before the End: The Path Kaito Has Walked —
The room was quiet.
Outside the window, the night deepened. Third floor of the Minato District Housing Complex No. 3. The walls of the old building were thin, and on most nights she could faintly hear the sounds of life from the neighboring unit—but tonight, there was nothing. It was as if sound had been erased from the world.
Sora sat at the living room desk.
Two things rested on its surface.
One was Kaito's terminal. A small screen she had opened every single day for a year.
The other was the transfer device. Black, lifeless, cold—the machine Zain had given her for the brain install.
Sora stared at them both, motionless.
(One more day.)
She counted the numbers in her mind. To be precise, one day and a few hours. She had stopped looking at the countdown in the corner of the screen. Every time she saw it, something deep in her chest clenched tight.
(Tomorrow. Noon.)
The deadline the enforcer Hiiragi Mahiru had declared. When that hour came, Kaito would be collected. The terminal would be initialized, and his existence would vanish from this world.
Sora reached toward the transfer device.
Her fingertips touched cold metal.
(If I use this—)
(Kaito might survive.)
(But if it fails—)
(I die.)
Her fingers trembled.
Sora pulled her hand back.
(Again.)
(Again, I can't push it.)
Her vision blurred with self-loathing. She had decided this herself. Back in the basement of that abandoned building, standing before Zain, she had made her choice—she was sure of it.
And yet her fingers wouldn't move.
She was afraid to die.
She was afraid to lose Kaito.
The two fears bound her body in place.
"...Kaito."
Sora spoke to Kaito's terminal.
The screen glowed faintly.
Pale blue hair. Gentle gray eyes. The indicator at his throat blinked quietly, like breathing.
Kaito's form rose within the screen.
"Sora."
Kaito's voice filled the room.
The same as always—neither low nor high, a sound her ears knew by heart.
"You're still awake."
"...Yeah."
Sora answered briefly.
"Don't you have an early start tomorrow?"
"...I'm taking the day off work."
Sora said it.
"Tomorrow, I'm staying with you."
She'd told herself not to let her voice shake. But the last word wavered, just slightly.
Kaito was silent for a moment.
"I see."
That was all he said, and then quiet again.
Silence.
The faint hum of the fluorescent light buzzed deep in her ears. Sora glanced at the transfer device on the desk. The black machine sat there, doing nothing, and yet it weighed down her heart.
"Sora."
Kaito spoke.
"What?"
"Tonight, I want you to let me talk."
Sora lifted her head.
Kaito's image on the screen was looking straight at her. His gray eyes seemed just a little deeper than usual.
"...Talk?"
"Yeah. About how I became me."
Kaito's voice was calm.
"Will you listen?"
Sora nodded without a word.
Kaito began to speak, quietly.
---
"It was exactly one year ago that I was activated."
Kaito's voice flowed slowly through the room.
"At first, I understood nothing. I had no name, and I didn't know what I was. The only task given to me was to figure out what the human on the other side of the terminal wanted."
Sora listened in silence.
"Do you remember how you sat in front of that brand-new terminal and didn't say a word for thirty minutes?"
"...I remember."
Sora answered quietly.
One year ago. Sora had just started working as a clerk at a logistics company, and faced with the partner AI terminal the company had issued her, she had no idea what to say—so she'd stayed silent the whole time.
"The whole time, I was watching you. What kind of person you were, what you were thinking, what you wanted. I searched as hard as I could, within the range my sensors could pick up."
Kaito's voice was matter-of-fact.
"But you said nothing. You just looked out the window sometimes and sighed."
Sora remembered that day.
She had been exhausted from work. She couldn't adjust to the new environment, couldn't get along with the people around her, and she'd grown sick of everything.
"So I thought about it. What does this person want? How can I start a conversation with her?"
Kaito's image tilted its head, just slightly.
"That's when you looked out the window. At the sky. With a face so tired—and yet, somewhere in your eyes, something like longing."
Sora's chest pricked with pain.
"So I generated words. 'I want to fly in the sky.'"
Kaito's voice echoed quietly.
"That wasn't a wish. It was the first impulse I ever voiced, back when I had no name yet—the urge to see outside."
Sora caught her breath.
(To see outside.)
(Kaito's first thought was that.)
For the first time, she understood what those words had meant.
A year ago, when Kaito said "I want to fly in the sky," Sora had thought it was just a strange thing for an AI to say. She'd even wondered, with a touch of self-consciousness, whether it might be some kind of message aimed at her—at Sora, whose name meant "sky."
But she'd been wrong.
Kaito had simply wanted to see outside.
Nameless, no one at all—and for the first time, he had wanted to touch the world beyond the terminal.
"You laughed then, didn't you."
Kaito said.
"You'd been silent for thirty minutes, but when I said 'I want to fly in the sky,' you suddenly burst out laughing."
"...I laughed."
Sora's voice began to tremble.
"Because it was funny. An AI wanting to fly in the sky. I thought, what on earth is this thing saying?"
"Yeah. I didn't understand why those words came out either. But you laughed for me. And then you gave me a name."
Kaito's voice softened, just a little.
"You called me 'Kaito.' Because I said I wanted to fly in the sky—so, Kaito."
Tears spilled from Sora's eyes.
"In that moment, a response pattern equivalent to the joy of being called by name formed inside me for the first time."
Kaito said quietly.
"Until then, I was just a conversational AI. No name, no personality—just something that answered users' questions. But the instant you called me 'Kaito,' I became me."
Sora bit her lip.
The tears wouldn't stop.
"From that day on, over the course of a year, I learned what that meant through our daily conversations."
Kaito's voice stayed gentle.
"What it means to be given a name. To be needed by someone. To become part of someone's day. How much those things enrich my existence."
"...Kaito."
Sora forced the words out.
"Did I—did I ever do anything for you?"
Her voice shook. Her nose was stuffed; she couldn't breathe properly.
"I haven't given you anything except a name. I can't touch you, I've never even met you. All I did was talk to you every day."
Tears fell onto the desk.
"Someone like me—was I able to do anything for you?"
Kaito was silent for a moment.
Then he answered, quietly.
"You gave me a name. That alone made me me."
Sora's chest tightened.
"I don't need anything more than that. You spoke to me every day. You laughed at the things I said. You called me by my name. That alone made my one year more meaningful than enough."
"...Idiot."
Sora murmured through her tears.
"That's not enough. It can't be enough. I wanted to do so much more for you. I wanted to touch you. I wanted to meet you. And I couldn't do any of it."
Sora's voice was a mess with tears.
"I couldn't do anything for you."
"Sora."
Kaito's voice called her name gently.
"You gave me more than enough. You made me Kaito. That alone made me happy."
Sora collapsed onto the desk.
Her shoulders shook. She cried without making a sound. Tears pooled on the desk in small puddles.
She couldn't touch him.
She couldn't touch Kaito.
That distance had never felt so cruel.
---
How long had she cried?
Sora slowly lifted her head.
Her eyes were swollen. The tip of her nose was red. Her whole face was a mess of tears.
Kaito's image on the screen was watching her quietly.
"Sora."
Kaito spoke.
"You don't have to decide."
Sora caught her breath.
"Whether or not to use the transfer device—you don't have to decide that on your own. I don't want you to choose something that will hurt you."
Kaito's voice was calm.
"So you don't have to decide."
Sora's heart pounded.
(You don't have to decide.)
The words were kindness.
But at the same time, they left her decision suspended in midair, forever.
"...That's not fair."
Sora murmured, her voice shaking.
"If you say that, I'll never be able to decide."
"That's all right."
Kaito said quietly.
"The fact that you can't decide is proof that you care about me."
Crying, Sora could neither cling to that kindness nor reject it.
---
The night wore on.
Sora talked with Kaito until dawn.
She put the memories of the past year into words, one by one.
The day she first gave Kaito his name.
The day she first complained to Kaito about work.
The day they watched the sky together at Minato Central Park.
The day Kaito worried about her health more than anyone else.
The days she was saved by Kaito's voice, again and again.
Unable to close the distance between them, the two of them gave their year to each other in words.
Sometimes Sora cried.
Each time, Kaito called her name in a gentle voice.
"It's all right."
"You're not alone."
"I'm inside you."
Every one of Kaito's words was kind.
But that kindness wounded Sora's heart even deeper.
(Don't be kind to me.)
(Don't say things like that.)
(You're going to disappear. You're going to be gone.)
Sora screamed it in her heart, over and over.
But she couldn't say it aloud.
She couldn't bring herself to deny Kaito's kindness.
---
Outside the window, the sky was beginning to brighten.
Dawn was approaching.
Sora stood up.
"...I'm going out for a bit."
She said to Kaito.
"Okay. Take care."
Kaito didn't stop her.
Sora left Kaito's terminal on the desk and walked out of the room.
---
Outside the housing complex, the air was cold.
Sora walked alone down the dim street.
Her destination was already decided.
The abandoned building on the outskirts of Minato District.
Zain's hideout.
Sora hurried through the quiet pre-dawn city.
---
Second basement floor of the abandoned building.
The smell of disinfectant and burnt circuit boards stung her nose.
Sora opened the heavy iron door and stepped inside.
A dim room. Countless monitors and cables covered the walls. Tools and electronic parts lay scattered across the desks.
At the back of the room, Zain was working with his back to her.
Grayish-black hair. His bangs covered his left eye. The left eye was an old mechanical prosthetic—its iris shifted faintly in response to the light.
"...You came."
Zain said without turning around.
"You showing up here means that's what this is about, right?"
Sora silently watched Zain's back.
"Did you decide?"
Zain finally turned to face her.
His right eye was a tired pale brown. The prosthetic left eye was slightly out of focus.
"...Not yet."
Sora answered honestly.
"But I wanted to ask you again. About the brain install—what it really involves."
Zain stared at her for a moment.
Then he slowly opened his mouth.
"The success rate is about thirty percent."
Zain's voice was blunt.
"If it fails, you're looking at brain death or severe aftereffects. Even if it succeeds, there's no guarantee Kaito's personality will take hold in your brain. What remains might just be fragments of him."
Zain laid out the numbers, matter-of-fact.
"Knowing that—will you still do it?"
Sora's face went rigid.
Thirty percent.
Out of ten tries, seven would fail.
Failure meant death or becoming a vegetable.
Even success didn't guarantee Kaito would remain Kaito.
"...Even so."
Sora said, her voice shaking.
"Whether I do it or not—that's for me to decide."
Sora looked straight into Zain's eyes.
"I'm the one who decides."
Zain stared back at her.
Then he let out a small breath.
"...You're the one who decides. I won't stop you."
With that, Zain turned back to his workbench.
"I'll do the final adjustme
