The train back to Tokyo was quiet and Kairo spent most of it looking out the window at nothing in particular.
Yuki was on the seat beside him instead of his back for once, legs pulled up, shoulder pressed against his arm, watching the side of his face with the attention she gave to things she was worried about but hadn't decided how to say yet. He could feel her looking. He didn't say anything about it.
She is the first and she will be the last and the others are only echoes.
Sixteen remain.
He turned it over the way he turned things he didn't have enough information for yet — not anxiously, just methodically, the way he'd approached every floor above Floor 23. What did he know. The archive had been built around something that already existed. The game had launched nine years after the first files were dated. Synchronisation was a stat only he and Yuki had. And now there were nodes — copies, echoes, whatever the Sapporo figure had been — sitting inside gates across the world, waiting, counting down to a file that would open today.
Today. The sun was coming up over the fields outside the window.
"You're going to think yourself into the floor," Yuki said.
"I'm thinking."
"You've been thinking since Sapporo. Your face is doing the thing."
"I have one face."
"You have the thinking face and the observing face and the face you make when I eat the last of something you wanted," she said. "Right now it's the thinking face but worse."
He looked at her. She looked back at him with the calm certainty of someone who had been studying a subject extensively and was confident in her findings. He looked back out the window.
"The Berlin payment cleared," he said.
She looked up. "Two million?"
"Yes."
She was quiet for a moment. "That's a lot of money."
"I'm buying a penthouse," he said.
She sat up fully. "What."
"The apartment is too small."
"The apartment is fine—"
"You've been hanging off me for six months in four hundred square feet," he said. "Which you'd do regardless of the space. But a penthouse has a better view."
She stared at him. He watched the fields. "When did you—"
"Sent the inquiry on the train to the airport yesterday."
"We were—" she stopped. Thought about the train to the airport specifically. What they had been doing. "You sent a property inquiry while I was on your lap."
"You were asleep. I had a free hand."
She looked at him for a long moment with an expression he couldn't entirely read. Then she grabbed his arm with both hands and pressed her face into his sleeve and made a muffled sound into the fabric. "What," he said. "Nothing," she said. "Nothing, you're just — you." She looked up at him, ears pink, the full smile. He looked at her and then looked firmly back out the window. "Can I see it," she said. He handed her his phone with the listing already open. She looked at it for four seconds. "There's a very large bathtub," she said. "Yuki." "I'm just noting it," she said, completely innocent, and kept scrolling.
The penthouse viewing was at noon.
The agent was a small precise woman maintaining professionalism through what appeared to be significant internal effort. She showed them the entryway, the ceilings, the kitchen, and then the main room — Tokyo in every direction, the bay to the south, Shinjuku to the west, the whole city spread out below floor-to-ceiling glass like it was presenting itself for inspection.
Yuki had her hands against the glass inside of twenty seconds.
"We closed a gate there," she said, pointing toward the Shinjuku district. "Seven months ago. There used to be a black circle right there." The agent followed her finger and nodded with the expression of someone filing this firmly under beyond my pay grade.
"We'll take it," Kairo said.
The agent blinked. "The viewing isn't quite—"
"I'll send the deposit today."
She made calls. Yuki found him in the hallway and stood in front of him and looked up at him. "You didn't check the second room," she said. "Checked the plan," he said. "What's it for." "Whatever you want," he said.
She went still for exactly one second. Then she stepped forward and put her arms around him, face against his chest. He put his arm around her and looked at the city over her head and said nothing.
"I want a plant," she said, into his chest.
"One plant."
"A large one."
"Yuki."
"The ceilings are high enough."
"Fine," he said. She made a satisfied sound against his shirt. The agent came back around the corner, stopped, looked at them in the white robes against the floor-to-ceiling glass with all of Tokyo behind them, and quietly went back the way she'd come.
They were back in the apartment by three.
It felt smaller now. Kairo sat on the floor against the bed and Yuki was beside him with the laptop open, the developer archive loaded, the new file sitting there with today's date on it like it had been waiting patiently.
"Ready," she said.
"Open it," he said.
She clicked.
Nothing happened for one second. Two.
Then the headache hit.
Not gradually — immediately, both of them, all at once, like something reaching directly through the space behind his eyes with a specific destination in mind. Beside him Yuki made a sharp sound and grabbed his arm and he realised she had it too, the exact same thing at the exact same moment, and neither of them had moved.
The laptop screen had gone white.
Text appeared. Not typed. Just there.
SYNCHRONISATION SEQUENCE INITIATED.0%.1%.
"Kairo—"
"I have it too," he said. "Don't close it."
2%.3%.
The pressure built with each number in a way that stopped feeling like a headache and started feeling like something with a destination. Her grip on his arm was getting tighter. He kept his eyes on the screen.
4%.5%.
The pressure spiked.
Yuki made the sound she made when something had actually hurt her — small, involuntary, immediately suppressed — and he turned toward her and the vision took him whole.
It didn't feel like watching something.
It felt like being somewhere.
He was on his knees in mud. Cold mud, deep, churned by too many feet moving too fast through rain. His knees were soaked through to the bone. His hands were shaking. He looked down and she was in his lap — rough commoner's cloth, undyed wool, her hair dark with mud and rain and spread out beneath her — and the cloth at her ribs had been cut through in five places and the wounds beneath were the kind his brain registered once and kept registering, over and over, the arithmetic of it, the irreversible arithmetic that didn't leave anything to negotiate with. Her insides were visible in the gaps and he had his hands pressed uselessly over them and she was looking up at him.
Red eyes. The same red eyes. Exactly.
Her lips were moving. She was saying something to him directly, clearly, without fear — he could see that, could see she was saying it on purpose and without panic — and he couldn't hear her over the sound coming out of his own chest. A sound with no shape and no ceiling. Something that had bypassed every filter he'd ever built for himself and was simply there, already fully present, his voice breaking apart against it. He was crying and he couldn't feel himself crying because the rest of it was too large. Behind him a village was burning. He registered it in fragments — soldiers moving through smoke with drawn swords, people running, the specific orange of fire catching on thatch roofs, screaming that wasn't his underneath the screaming that was. None of it registered as something that required his attention. None of it existed in any meaningful sense. There was only what was in his lap and the useless pressure of his hands and the red eyes that were still open, still looking at him, still present.
She raised one hand.
It trembled badly. She raised it anyway, all the way up, and she pressed her palm against his jaw — just held it there, warm despite everything, just her hand against his face — and she was looking at him with those eyes and saying something he still couldn't hear and he bent toward her, bending completely over her, as if getting closer would let him hear, as if proximity could fix the arithmetic—
The earth moved.
Not an earthquake. Not anything structural. Something responding — the ground registering the sound coming out of his chest and deciding it agreed, deciding that whatever was contained in that sound deserved acknowledgment from the ground up. The mud shifted under his knees. Something behind him fell. Somewhere in the smoke the soldiers stopped moving and one of them looked at the sky because the sky was doing something it wasn't supposed to do.
He didn't look at the sky.
He was looking at her hand on his face. At her lips still moving. At her eyes, which were still open, still the same red, still—
Still.
The specific quality of that moment had a border in it, a before and an after, and his whole body knew which side of the border he was on now and the sound that came out of him when he understood it wasn't screaming anymore. It was what came after screaming. It was the thing underneath the screaming that the screaming had been covering and now nothing was covering it and it had no name and the mud was cold and her hand was sliding from his face and he caught it and held it and held it and held it—
SYNCHRONISATION PAUSED.5%.
The screen held on those words and didn't move.
The headache stopped.
Kairo was crying.
He didn't know when it had started. It was already fully present when the vision cut off — no lead-up, no build, just there, real and without his permission, belonging to a version of himself in rough wool kneeling in burning mud. His whole chest hurt with something that wasn't his and also was completely his. He could still feel the weight of her in that version's arms. Could still feel the exact shape of the moment her hand had slid from his face. His body didn't know the difference between something that had happened to him and something that had happened to a version of him five seconds ago and apparently had no interest in learning.
Yuki made a sound beside him.
He turned and grabbed her.
Both arms, fully, before the thought was complete — pulling her against his chest and pressing his face into her hair and holding on with the specific grip of someone whose hands remembered exactly what it felt like to hold on and have it not be enough. She made a soft broken sound against his shirt, something she didn't try to suppress, and held him back immediately with everything she had. Both arms around him. Face against his chest. No hesitation, no question, no pulling back.
He pressed her closer.
She let him. She didn't move, didn't shift, didn't try to pull back to look at him. She just stayed exactly where she was and held on and let him hold her and the apartment was small and familiar and dim around them and nothing in it was burning. He could feel her heartbeat against his chest. He could feel her breathing. He pressed his face further into her hair and catalogued every point of contact between them with the deliberate thoroughness he gave to things that mattered — she was here, she was warm, she was breathing, she was here.
He held her tighter anyway.
She didn't say anything for a while. Just held him. Just stayed. At some point her hand moved to the back of his neck and rested there, warm and still, and he felt the specific care in it — not trying to fix anything, not asking anything, just present.
"I'm here," she said, eventually. Very quietly. Into his shoulder. "Right here."
He pressed his lips to her hair and kept them there.
"I saw you," she said, quieter still. "Through her eyes. What happened to you."
He didn't answer that. He pulled back just far enough to look at her face — actually look at it, her eyes, the red that was open and present and looking directly back at him — and something in his chest registered the specific aliveness of them in a way it hadn't before and probably would never stop doing now. He pulled her back in. She tucked her face into his neck and wrapped her arms around him again without being asked and stayed there completely.
The laptop sat dark on the floor beside them.
5%.
Only five. Whatever the sequence was building toward had barely started and had already done this much. He didn't know what a hundred percent looked like. He didn't know what the file contained or what the synchronisation was connecting or why it had stopped. He didn't know what the vision was or where it had come from or what the version of himself in commoner's wool had done next, kneeling in the mud with the earth shaking around him.
He held Yuki and looked at the wall and thought about all of it and none of it had answers yet.
But she was warm against him. Her heartbeat was steady under his hands. Her hair smelled the same as it always had and her arms were around him and outside Tokyo was going on being Tokyo, indifferent and enormous and completely unaware of any of this.
"I'm not going anywhere," she said, like she'd heard the thought.
He said nothing.
He held her tighter, and she held him back, and he stayed exactly where he was for a long time.
