They'd been back maybe twenty minutes when Yuki said, "I'm hungry again."
Kairo looked at her.
"You just ate an entire bowl of ramen," he said.
"I know."
"Plus the broth."
"I know."
"I told you not to drink the broth."
"Kairo."
"You burned your own mouth."
"I was there." She looked at him with great patience. "I remember all of that. I'm just telling you I'm hungry again. Bodies are extremely demanding. Nobody warned me about this."
He picked up his phone. She leaned over his arm immediately, chin on his shoulder.
"Not spicy," she said.
"You ordered the spicy miso."
"And I have grown since then."
"That was four hours ago."
"I'm a fast grower." She pointed at the screen. "That one. And that one."
He looked at the total. "You're ordering for four people."
"I've had a very long day," she said, with enormous dignity.
He ordered it.
The food arrived and they sat on the floor in front of the coffee table. Yuki cross-legged, Kairo beside her because she'd put his portion next to hers without asking.
She took a bite. Her face did something involuntary — that concentrated, helpless delight she clearly hadn't prepared for. She tried to put it away and didn't manage it.
"You made a sound," he said.
"That was breathing."
"You were making sounds while breathing."
"That's called breathing—"
"Eat your food," he said.
She ate. The sound happened again and this time she just accepted it. He watched the side of her face and she could feel it.
"Stop cataloguing me," she said.
"I look at everything like this."
"It's different when it's me." She glanced at him. "It's like being studied by someone who finds the results interesting but won't tell you what they are."
"That's accurate," he said.
She pointed a chopstick at him. "Not a compliment."
"I know," he said, and went back to eating.
She stared at him for a second. Then she also went back to eating, but kept glancing at him sideways with the expression of someone who had started a project.
His phone rang an hour later. Official prefix.
"Kairo Azren. Metropolitan Crisis Response Unit. We'd like to speak with you tonight."
He hung up.
"Government," he said. "Coming here."
Yuki stood and had her arms around his neck before he'd finished the sentence. Legs off the ground. Chin on his head. He adjusted without comment and they waited.
They came eleven minutes later. Two of them — a broad combat-build man and a quieter woman. Dark clothes trying to look civilian.
They looked at Kairo. Then at Yuki on his back. Then back at Kairo.
"Forty-three active gates," the woman said. "Twelve in populated areas. You're the only confirmed methodology we have."
"No," Kairo said.
"People are—"
"I went in because it was four blocks from my building," he said. "That's all."
The man's hand shifted toward his side. Small movement.
Detection spread outward in a quiet pulse. Two more people on the floor below. He mapped all four of them in under a second — their builds, their positions, what they could and couldn't do — and felt nothing in particular about any of it.
"Don't," he said.
The man stopped.
"I can tell exactly where the people you left downstairs are standing," Kairo said. "What order they'd need to come through this door for it to matter." A pause. "It wouldn't matter."
The woman put her hand on the man's arm. "Stand down." Then to Kairo, straight: "The gates aren't stopping. Eventually this is everyone's problem."
"When it's mine," he said, "I'll handle it."
She held his gaze for a moment. Then she nodded once and they left.
The door clicked shut.
Kairo stood in the middle of the apartment for about one second, then turned back to the desk and sat down. Yuki slid off his back into her chair, tucked her legs up, shoulder against his.
"That's it?" she said.
"That's it," he said.
She looked at the door. Then at him. "You weren't even a little concerned."
"No."
"Four people."
"They weren't a problem." He opened the laptop. "They knew it too."
She looked at his profile for a moment with the particular expression she wore when she was deciding if she should push something. She decided not to. She settled her chin on his shoulder and looked at the screen with him.
They were back at the desk, map on the laptop, more red dots than before, when the knock came.
Urgent. Uneven.
Detection — one person. Fast heartbeat. Afraid. Not a fighter.
He opened the door.
A boy. Seventeen maybe, school uniform half-hanging off one shoulder, a shallow cut on his forearm that looked like gate debris. Status window barely in double digits. He looked at Kairo like he'd been hoping very hard this was the right door.
"You're from the Shinjuku footage," he said. "I saw which street you turned onto when you walked away from the gate. I've been knocking for twenty minutes." He stopped. Steadied himself. "There's a gate two streets over. Floor Four. My friends went in forty minutes ago. I held on but they couldn't." His voice cracked on the last word. He pressed it back under. "Nobody else would come."
Kairo looked at him for a moment. Then he turned back inside for his jacket.
Yuki was already on his back.
"Floor Four," he said quietly. "Slow variants. If they kept moving they're okay."
"Forty minutes is a long time," she said.
"They're okay," he said, and meant it. He looked at the boy. "Show me."
The gate was in an alley two streets over. Small — barely wider than a doorway, the number 4 on its face. The pull at this distance was mild.
Detection through it in two seconds. Two heartbeats. Eastern wall. Alive.
"East wall," he said. "Both alive."
The boy let out a breath that was most of what he had left.
"Stay here," Kairo said. "Don't move closer."
They went through.
Stone and moss, dim blue-green light, the smell of damp rock. Two slime variants in the main corridor, large and slow, both facing away from two girls pressed against the far wall completely still.
Yuki shifted on his back. "I want to try something. I think I can make things not notice us."
"Tell me before we go in next time," he said. "Not during."
"I know. Can I try it now."
He looked at the distance. "If it doesn't work I move immediately."
He felt it leave her — not sound, not pressure. Something closer to the absence of both. A stillness spreading outward from her like a held breath.
The slimes stopped. Both of them. Mid-movement, attention simply switched off.
He moved.
Flash Step. First variant. Moon Slash through the core, clean and quiet. It folded. Back to the second before the first hit the ground. Same motion. Done.
Eleven seconds.
The corridor went still.
They came back out into the alley.
The boy grabbed his friends the moment they cleared the gate. The girl who'd been sitting started crying immediately — the shaky, relieved kind, forty minutes of held-together finally letting go. The boy held her and looked at Kairo over her head with an expression that had too much in it.
"Thank you," he said. Twice. Like once wasn't close to enough.
The gate folded behind them and was gone.
"Ten metres from any gate," Kairo said. "The number on the outside is the floor. The higher it is, the further back you stand."
The boy nodded.
They walked home.
"Your ability," Kairo said, two blocks out.
"It felt like making things unimportant," she said. "Like convincing the space we weren't worth noticing."
"It's not in any skill list from the tower."
"No," she said. "I think it's just mine."
He thought about that. Her stats higher than his across the board. An ability that didn't exist anywhere in the game. Sitting on the hundredth floor looking at clouds like she'd been waiting for something she didn't have a name for yet.
"You're not what the hundredth floor was supposed to have," he said.
"What was it supposed to have."
"Nothing," he said. "There was never meant to be anything up there."
She rested her chin on his head. "And yet here I am."
"And yet," he said.
Back upstairs. Desk. Lamp on. Shoulder against his. Hand on his sleeve. The map had more dots.
He hadn't felt this before. Not once in seventeen years. He had kept every person at a careful managed distance and maintained it without effort because nothing had ever threatened it. Nobody had ever been worth closing it for.
He looked at her from the side.
She was watching the map, chin on her knees, completely unaware. The lamp light in her hair. Her sleeve-covered hands folded around her legs.
He looked back at the screen.
Then — "Your status window has a height field."
She looked at hers. Scrolled. Found it.
A silence with a very specific shape.
"That's wrong," she said.
"It's your window."
"I'm 5'3"."
"It says 5'2"."
"Then it's broken." She looked at the point on his shoulder where the top of her head always sat. Stared at it for a long moment. And then her face went — slowly, helplessly, like something careful finally giving up.
"Wuahhhh—" small. Involuntary. "Sniff." Both sleeve-hands came up over her face. "That's so short."
"It's not—"
"You're 6'4"!!" She looked at him over her sleeves, eyes bright, genuinely wounded. "Sniff. I didn't know. I was just living my life—"
"You've had a life for two days—"
"It was a good two days! I felt normal!" The sound again — "Wuahhh... sniff, sniff—"
And then she was actually crying.
Not dramatically. Just quietly, behind her sleeves, real tears on her face — silly reasons, height and a number on a window and two days of everything at once — but real.
Kairo went very still.
He had absolutely no idea what to do.
He looked at her. He looked at the laptop screen. He looked back at her. She was still making the small sounds and her shoulders were up around her ears and he was sitting completely useless because he had never — not once — sat next to someone crying and felt like the entire problem was somehow his to fix. He could handle four government operatives without his heart rate changing. He had cleared a hundred floors alone without hesitating once.
He had no idea what to do about this.
"Yuki," he said.
"Sniff. I'm fine—"
"You're not fine."
"It's just the height thing—"
"You're crying."
"I'm aware—"
"Stop," he said, and it came out wrong — too sharp, not what he meant at all — and she looked at him over her sleeves with wet eyes and something in his chest did something completely unfamiliar and slightly awful.
"I didn't mean—" He stopped. Started again. He rubbed the back of his neck, which he never did. "I don't know what to do when you cry."
She blinked.
He looked at her with the expression of someone making a confession they hadn't planned. "I've never — this hasn't happened before. Any of this." He paused. "You. This. I don't know what I'm supposed to do right now and I don't like not knowing."
She stared at him.
"You're worried," she said slowly. Not teasing. Just realising.
"Yes," he said, like it cost something.
"About me crying."
"About you," he said. "In general. Since you got here."
Her eyes got brighter, which was the wrong direction entirely.
"Don't," he said, slightly alarmed. "Don't cry more—"
"I'm not—" she pressed her sleeves to her face. "Sniff. This is different crying—"
"There are different kinds—"
"Yes!" She looked at him, eyes completely wet, smiling behind her sleeves just barely. "The first kind was about being short. This kind is because you just said that."
He looked at her. She looked back at him, nose pink, eyes bright, completely at his mercy and not even pretending otherwise.
He reached over and pulled her into his side. Properly. His arm around her, her face going into his shoulder, her sleeve-covered hands pressing against his shirt. He pressed his lips to the top of her head and stayed there.
He had no words. He'd never needed them like this and he didn't have them now. But she wasn't moving and he wasn't moving and her shoulders slowly stopped shaking and after a while she exhaled against his shirt — long and slow, like something releasing.
Neither of them said anything for a while.
"Kairo," she said eventually. Quiet. Muffled by his shirt.
"Mm."
"You've never liked anyone before."
It wasn't a question.
"No," he said.
She pressed slightly closer. "Me neither," she said. "But I think I like you a very worrying amount."
He looked at the top of her head.
"Same," he said.
She made a small sound against his shoulder that was almost a laugh. He held her and the lamp was on and outside the city moved through its difficult night.
Inside was warm and still.
"I'm 5'3"," she said. One final time. Quiet.
"Sure," he said.
She held his sleeve. He held her.
