She woke up when the plane began descending.
Not from the movement — from him. He'd been drawing something on the back of her hand with his finger while she slept, slow and absent, tracing patterns she couldn't see. She became aware of it gradually, the light pressure of it, and lay still pretending she was still asleep because she didn't want him to stop.
He stopped anyway. "You're awake."
"How do you always know?!"
"Your breathing changes." Simple. Certain. Like he'd memorised the exact sound of her sleeping and catalogued the moment it shifted. She sat up and looked at him and he looked back completely unbothered by how devastating that was to hear.
"What were you drawing?" she said.
"Nothing."
"On my hand, just now—"
"Nothing." His ears moved slightly. Just slightly. She decided to keep that.
Cairo appeared below them brown and ancient and sprawling, the Nile cutting through it like something permanent. She pressed her face to the window.
"It's so old," she said.
"One of the oldest cities in the world."
"You can feel it from up here." She turned. "Can you feel it or is that just me?"
"Just you," he said, and she could tell he was at least partially lying, which meant he felt it too and wasn't going to say so, which was fine. She was keeping that as well.
The government liaison in Cairo had sent a car and a clothing package.
Someone had apparently noticed that two people clearing international gates in floor-length white robes was generating significant media attention and had decided to address this by sending — Yuki opened the bag — actual clothes.
She held up a black jacket. Looked at Kairo.
"Someone on the internet said the robes were impractical," she said. "They're not wrong but I'm offended anyway."
"Wear it over the robe."
"That defeats the point."
"The point being?"
"Looking like we came from somewhere that doesn't exist." She put the jacket down and looked at the rest of the bag — dark clothes, practical, chosen by someone who'd watched the gate footage and decided white floor-length fabric was a liability near high-pull environments. She picked up a black turtleneck and held it against herself. "What do you think?"
He looked at it. "Wear it."
"Just like that? No deliberation?"
"Black suits you."
She stared at him. He picked up his own set — dark trousers, a charcoal shirt — and went to change without further comment, leaving her standing there with pink ears.
They reconvened in the hotel room.
She turned when he came back and stopped.
He was in the dark clothes and his white hair was — that was genuinely unfair. The contrast of it, white against dark, the red eyes. She'd seen him in white for seven months and somehow forgotten other colours existed and did things.
"What," he said.
"Nothing." She turned back to the mirror and fixed her collar. "You look good."
"So do you."
She met his eyes in the reflection. He was looking at her with the turned-up thing — direct and open and not trying to be anything else. He came up behind her and pressed his mouth to the side of her neck. Just briefly. Warm and deliberate.
She grabbed the dresser.
"We have a gate," she said, with admirable composure.
"I know." He straightened up. "Ready?"
She turned around. "You can't do that and then say ready."
"Why not?"
She kissed him instead of answering — quick and pointed — and he caught her face and made it considerably less quick, and by the time she pulled back they were behind schedule.
"Now I'm ready," she said.
Something close to a smile. "We're late."
"You started it."
"I didn't."
"You absolutely did." She grabbed her jacket. "Let's go."
Cairo's Floor 62 gate was in the old industrial quarter, wide enough that the cordon had been pushed back three hundred metres and buildings at the edge still showed structural damage. The pull was significant even from distance. Yuki felt it as pressure in her chest — that specific wrongness that announced something that shouldn't exist.
"Big," she said.
"Compound interior," he said, studying it with the flat focus of someone running calculations. "Multiple boss variants. First cluster, then a secondary wave forty seconds after. Don't stop moving after the first clear — second wave comes from behind."
"Where do we position for it?"
He pointed to the upper left of the cavern space. "Elevation. Secondary wave spawns low so height gives us the angle."
"Flash Step vertical in the window?"
"Yes."
His hand found the back of her neck briefly — just present, just checking — and she turned to find him looking at her with the expression she'd learned to read as something he wasn't going to say out loud.
"Kairo."
"If it goes wrong—"
"It won't."
"If it does—"
"Kairo." She stepped forward and grabbed his jacket. "I've been in every gate with you since Floor 7. Floor 23 fog. Floor 73 swarms. I've never once—"
He kissed her.
Right there, with the pull making the air taste wrong and officials behind the cordon carefully not looking. Brief and certain.
"I know," he said, against her mouth. "I know you haven't. I just—" he stopped.
She looked at him. This was new — him stopping mid-sentence because the rest of it was something he hadn't figured out how to say yet. The vision. The mud. The weight of something that had happened before, in some other version of things that wasn't this one.
She put her hand flat against his chest.
"Right here," she said. "Same as always."
He covered her hand with his and held it there for a second. Then turned toward the gate.
She climbed onto his back.
Floor 62 was cavernous and dark, the first cluster enormous and moving in overlapping patterns. He didn't engage sequentially.
Flash Step through the cluster at sixty percent, Moon Slash extending in a wide arc, catching four contacts simultaneously. He pulled out before the formation recovered. Yuki's ability was already spreading — that radiating silence making them functionally invisible to the secondary sensor type in the group.
"Three remaining," she said. "Two o'clock, nine o'clock, directly below."
He took the one below first. The flanking two moved to intercept. He was already gone — Flash Step horizontal, taking them from behind with two clean cuts.
Thirty-eight seconds.
He went vertical immediately.
She held on tight as they shot straight up into the cavern ceiling, her face against the side of his head, and below them at exactly forty seconds the secondary wave emerged — faster variants, spreading low across the floor.
"Now," she said.
He came down through the centre with Moon Slash at full output, the crescent extending further than she'd ever seen him push it, cutting a clean path through the entire cluster in one motion.
Silence.
The gate closed.
They came back through into Cairo sunlight and the heat hit immediately — dry and ancient and completely unlike anything else. Yuki lifted her face from his hair and looked around.
The officials at the cordon had their personal phones out. Not the official cameras. Their own.
"They're filming," she said.
"They always film."
"With their own phones. That's different." She watched them. One official said something in Arabic. Another replied, pointing at both of them, and whatever the word was made two others nod with great conviction.
She asked the liaison about it in the car.
He looked briefly like he'd rather not answer. "They have a name for you," he said carefully. "On Arabic social media — it translates roughly to The Eternal Ones." He paused. "The English internet picked it up this morning. Someone posted a thread comparing historical records across different ancient cultures, finding similar descriptions, and it—"
"How many views?" Yuki said.
He checked his phone. "Combined? About two hundred million."
The car went quiet.
Yuki turned to Kairo with enormous eyes. "The Eternal Ones," she said.
"Don't," he said immediately.
"That's incredible—"
"It's dramatic—"
"It's PERFECT!" She grabbed his arm with both hands. "We clear ancient gates in robes and now we have an ancient name to match — Kairo, that's iconic, that's genuinely—"
"It's embarrassing," he said, with the flat certainty of someone who had made up their mind.
"It's not embarrassing it's amazing!" She turned to the window and then back to him, still holding his arm. "The Eternal Ones. Us. That's us."
"You're enjoying this too much."
"I'm enjoying it exactly the right amount!" She looked at him properly then — at his jaw, at the way he was looking very deliberately out his window, at the colour that had come up at the back of his neck. Her expression changed entirely. "Kairo."
"Mm."
"You're blushing."
"I'm not."
"You are! You're actually—" she leaned closer and he leaned slightly away, which only confirmed it, "—you're blushing over a name! That's so—" she pressed both hands to her mouth, eyes bright with the effort of containing something, "—that's so cute—"
"It's not cute, it's a reasonable reaction to an unreasonable—"
"It's not even the first time I've seen you blush!" She was smiling enormously now, the full unstoppable one. "Last night when you were in—"
His hand covered her mouth.
Fast. She hadn't even seen it coming. His palm flat against her lips, his expression doing something she'd never seen before — the specific combination of composed and completely not composed, the tips of his ears red, his gaze aimed at the ceiling like it had personally wronged him.
Her eyes were enormous over his hand.
She was laughing. He could feel it against his palm.
The liaison was looking out his window with the rigid focus of a man who had decided he was somewhere else entirely.
"Don't," Kairo said. His voice came out mostly steady. Mostly.
She laughed harder. He kept his hand where it was and looked at the ceiling and the colour on his neck was not going anywhere and she reached up and curled her fingers around his wrist — not pulling it away, just holding it there — and her eyes were absolutely shining above his hand.
He moved his hand.
"Not in a car," he said.
"I was just going to say—"
"I know what you were going to say."
"You don't know—"
"Yuki."
She bit her lip. Looked at him. His jaw was set and his ears were red and he was looking at the window with the expression of someone exercising genuine restraint and she loved him so completely it was almost inconvenient.
"The Eternal Ones," she said softly, no teasing left in it this time.
He looked at her from the corner of his eye.
She threaded her fingers through his on the seat between them. "I like it," she said simply. "That's all."
He looked at their hands. The colour at the back of his neck didn't fully disappear but something in his expression softened.
"It's still dramatic," he said.
"Everything about us is dramatic," she said. "You summoned me out of a video game."
A beat. "Fair," he said.
She leaned her head on his shoulder and he didn't move away and outside Cairo went past in all its ancient unhurried permanence and the liaison found the window very interesting for the rest of the drive.
That night the archive sent a notification.
Not the synchronisation file — a different one. A partial decrypt on one of the redacted sections, three paragraphs now suddenly readable. Yuki had the laptop open on the hotel bed before Kairo had finished reading the alert.
She went quiet almost immediately.
He came and sat beside her and read over her shoulder.
The text was clinical — project terminology, internal references, dry documentation language. But the shape underneath it was clear enough.
The synchronisation stat wasn't a game mechanic.
It had never been a game mechanic. The game had been built around it — structured specifically to bring two people with specific stat profiles into contact on the hundredth floor. The floor had been designed with no boss. The NPC classification had been a cover. What sat on Floor 100 had not been built by the developers.
It had been found.
Yuki read that line twice.
"Found," she said.
"Yes."
"They found me." She looked at the screen. "Before the game existed. Twelve years ago. They found something and built the entire game around getting you to it."
"Around getting someone specific to it," he said. "The stat profile — it's not general. It's coded to one person."
She looked at him.
"They built it for you specifically," she said.
"Yes."
The hotel room was quiet. Cairo outside was doing its ancient patient thing, city noise low through the walls. Yuki read the three paragraphs again, slower.
"What did they find?" she said quietly. "What am I?"
He didn't answer because he didn't know yet. His arm came around her and pulled her in anyway and she let him, leaning into his side, the laptop open in front of them with its three paragraphs of partial answers and the locked file sitting above it, waiting.
"We'll find out," he said.
"I know." She closed the laptop. "Not tonight."
"No," he agreed. "Not tonight."
She turned and kissed him — not the quick kind, the slow deliberate kind she had for moments when something large had just landed and she wanted to be certain about at least one thing. He kissed her back and pulled her closer and she thought: found. They found her. Then spent nine years building a road to get him there.
She pulled back and looked at him.
"The Eternal Ones," she said, quietly. No teasing in it this time. Just the weight of it.
He looked at her. The unmanaged version, the open one. "Yeah," he said.
She put her head on his shoulder.
Outside Cairo held its thousands of years like they were nothing. Inside the hotel room two people sat with a partial answer and sixteen remaining questions and the certain knowledge that whatever they were to each other had been true long before either of them had been around to know it.
Some things were very simple.
