They were halfway down the parking structure stairs when Kairo stopped.
Yuki walked into his back.
She stepped back and looked up at him. He was looking at the wall like it had said something mildly interesting.
"What," she said.
"The gate is four blocks from our building."
She waited.
"It's going to keep pulling things in," he said. "Cars, debris, people who don't know the radius. Eventually something comes out of that floor and then it's a problem that's literally at our door."
Yuki looked at him. "You said you weren't getting involved?"
"I said I hadn't decided yet."
"You very specifically said not today?"
"Today's not over."
She stared at him. He had already started walking again, hands in his pockets, completely unbothered.
"Kairo," she said, following him.
"It's Floor 7," he said over his shoulder. "I've killed that crawler forty-two times. It takes about four minutes on a bad day and I wasn't even trying most of those."
"So you want to go in?"
"I want to close it. There's a difference." He pushed through the stairwell door onto the ground level and held it open for her. "The crawler dies, the floor clears, the gate closes. Then it's not our problem anymore."
Yuki walked through the door and stopped in front of him.
"Our problem?" she said.
He looked at her. "You're coming."
She blinked. "You're asking me?"
"You wanted to go outside. The gate is outside. It's efficient."
"That is the least romantic way anyone has ever asked someone to do something together."
"It's not romantic. It's pest control."
She looked at him for a long moment. Then she looked down at her hoodie sleeves and pushed them up with the expression of someone who had made a decision.
"Fine," she said. "But I want that warm food after."
"Fine."
"And you have to actually ask me next time instead of just announcing it."
"Would you like to come?"
She smiled. Just briefly. "Yes."
She stepped up onto the lowest stair behind him, bringing herself level with his back, and looped her arms around his neck from behind. Her legs came up off the ground completely, her chin settling on top of his head, her weight easy across his shoulders.
He adjusted without comment and started walking.
"You didn't even hesitate?" she said from above him.
"You do this constantly."
"You could tell me to get down?"
"I could," he agreed.
He didn't.
The cordon was a mess.
Six officers holding a line, two news vans at the outer edge of the block, a cluster of people behind a barrier all holding up phones, and three people in tactical gear near the gate who had been arguing in the same spot since the support-build incident.
Kairo walked toward the cordon with Yuki on his back. She had her chin on his head and her legs dangling and was looking around at everything with the quiet curiosity of someone experiencing a street level view of Tokyo for only the second time in her life.
"There are a lot of people?" she said.
"More than I'd like."
"Are they all scared?"
"Some. Some are filming."
She looked at the people holding phones behind the barrier. "Of the gate?"
"Probably us too at this point."
She went slightly still on his back. He felt it.
"Should I get down?" she said.
"Does it bother you?"
A pause. "No," she said, and settled her chin back on his head.
One of the officers held up a hand as they approached. "Sir, this area is restricted—"
"I'm going in," Kairo said.
The officer looked at him. Young, probably first year, his hand still raised uselessly in the air. He looked at Yuki on Kairo's back. She gave him a small wave with two fingers, her sleeve flopping over her hand.
The officer's hand slowly lowered.
"You're… going in?" he said.
"The gate is four blocks from my apartment," Kairo said. "It's annoying."
He walked past him.
There was a brief strangled sound from behind them as the officer tried to decide whether to stop him and concluded he probably shouldn't.
The tactical gear woman near the gate turned as they approached. Mid-twenties, dark circles, the look of someone who hadn't slept and was running entirely on responsibility. She looked at Kairo. Then at Yuki, still on his back, arms around his neck, chin on his head, legs dangling, oversized white hoodie, complete composure.
She opened her mouth.
Closed it.
Looked at both of them again — the white hair, the red eyes, the matching everything, the calm that sat on them like they had somewhere better to be and were doing this on the way.
"Who are you?" she said finally.
"Someone who's cleared that floor before," Kairo said.
"That's not an answer?"
"It's the only one that matters right now."
She stared at him. He looked back at her with the flat unhurried expression he wore everywhere, and after a few seconds she seemed to decide that pressing further wasn't going to get her anywhere useful.
"There's a civilian in there," she said, redirecting. "Pulled through about twenty minutes ago."
"Support build, wrong approach angle," Kairo said. "I watched."
"You watched?"
"From the parking structure."
She stared at him. Yuki's chin was still resting on his head. The woman looked at her, as if looking for some confirmation that this was normal. Yuki offered nothing.
"They've been in there twenty minutes," the woman said.
"They're hiding," Kairo said. "The crawler doesn't pursue into tight spaces. If they found a corner in the first thirty seconds they're fine." He looked at the gate. "Terrified, but fine."
She absorbed this. "We were about to send a team."
"Don't," he said. "The crawler has a phase where it seals exit routes. Multiple targets trigger it. One person moving fast doesn't." He paused. "Send them in after I come back out if you want. The floor will already be clear."
The woman looked at him for a long moment. Then at Yuki.
"Is she going in too?" she said.
"She is," Yuki said pleasantly, from on top of his head.
The woman looked like she had several things she wanted to say and was choosing not to say any of them.
"At least tell me your name?" she said. "In case you don't come back out."
"We'll come back out," Kairo said.
He walked toward the gate. Yuki rode his back with the complete composure of someone who found this entirely normal and waved at the woman over his head with two fingers as they passed.
The woman watched them go. Around her the officers who had been close enough to hear the exchange were looking at each other.
Nobody had an explanation.
They stood at the gate threshold.
The pull was steady from here, a constant low pressure, and the air around it had that specific quality he remembered from standing in front of floor portals — slightly wrong, like a room with no windows.
Yuki's arms tightened slightly around his neck. Not from fear. Taking it in.
"It looks different up close," she said.
"Worse or better?"
She considered it. "Just different." A pause. "Still ugly."
"Going in now," he said.
"Okay," she said, and held on.
He walked them both through.
The Floor 7 environment landed around them the same as always. Cold stone, low ceiling, the smell of damp rock. The temperature dropped immediately and Yuki's arms tightened around his neck.
"Cold," she said.
"Cold climate floor."
"You could have warned me?"
"You'll be fine."
"That's not what I said."
He activated Detection. Mapped everything in two seconds. Crawler in the central chamber. One human presence, eastern alcove, alive.
"Civilian's east," he said. "Alive."
"Told you," Yuki said from his back.
"I said probably."
"Same thing."
He moved toward the central chamber. Yuki stayed on his back, arms around his neck, legs off the ground, and said nothing because she could feel the shift in him — the way his steps changed, quieter, deliberate, the particular quality of attention he had when something was about to happen.
She stayed very still and held on.
He looked down at his empty hands.
No katana. He flexed his right hand slowly, feeling the mana sitting in his body the way it always did now — present and real, no headset required.
Moon Slash wasn't a weapon technique. It never had been. The blade was wherever he decided it was.
He let the energy run down his forearm and settle along the edge of his hand, thin and cold and faintly luminescent, like light held just below the skin.
That would do.
The crawler was where it always was.
It turned the moment he entered the chamber, plating catching the ambient light, joints making the low mechanical sound he had heard forty-two times. It registered him as a target and it registered the weight on his back and it began moving.
He was already faster.
Flash Step in a real stone corridor hit differently than the game — the shockwave off the walls came back at him and he adjusted mid-movement, Adaptive Combat filing it away without being asked. Everything was heavier here, more present, the ground pushing back, the air resisting, and it was better for it.
Yuki's grip tightened around his neck when he moved. Not panic. Just holding on, adjusting her weight the way she always did, her chin tucked now against the side of his head instead of on top of it.
Third pass. Edge Retention stacked.
He brought Moon Slash down through the joint between the second and third dorsal plates with the edge of his hand, the energy releasing in a single clean line that went exactly where he sent it.
The crawler made a sound it had never made in the game — lower, more real, more final — and then nothing.
Twenty-three seconds.
He let the energy dissipate from his hand and shook it once. Yuki slowly uncurled from where she'd tucked herself against his neck and lifted her head.
The chamber was quiet.
"That was your hand," she said.
"Moon Slash works on whatever edge I give it."
She looked at the side of his face. He could feel it. "You fought a floor boss with me on your back."
"It's Floor 7."
"With me on your back," she said again.
"You weren't heavy."
She stared at him. He started walking toward the eastern alcove and she stayed on his back and said nothing for a moment, and then very quietly, to herself more than him, said, "That was the coolest thing I've ever seen."
"You've been alive for less than a day."
"Still counts," she said, and pressed her chin back on top of his head.
The civilian was a delivery driver in his thirties, jacket, company logo, the full evidence of someone who had been extremely in the wrong place. He looked up when they came around the corner with the expression of someone who had made peace with dying and was now confused about why that hadn't happened yet.
He looked at Kairo.
He looked at Yuki on his back, chin on his head, legs dangling, completely at ease.
White hair. Red eyes. White hair. Red eyes.
"Are you two—" he started.
"No," Kairo said.
"We're not siblings," Yuki said.
The man blinked. "I was going to ask if you were angels?"
A silence.
Yuki turned her face toward Kairo's ear. "He thought we were angels," she said.
"We're not," Kairo told the man.
"He thought we were angels," she said again, louder.
"Can you walk?" Kairo asked the man.
The man looked at Yuki, who was still quietly glowing about the angel thing. "Are you sure you're not—"
"Let's go," Kairo said.
They came back through the gate into cold morning air.
And then something happened that nobody was prepared for.
The gate didn't stay.
It started slowly — the edges pulling inward the way smoke pulls toward an open window, the dark void thinning at its border, the number 7 on its face flickering once, twice, and then going dark entirely. A low sound came from it, deep and resonant, felt more than heard, the kind that made the officers at the cordon step back without deciding to.
The crowd went completely silent.
The gate folded. Not violently — it simply drew itself inward, smaller and smaller, the air sighing back into the space it had occupied for twelve hours, until there was nothing left but an empty intersection and debris on the asphalt and a faint smell like rain on stone that faded within seconds.
Nobody moved.
Then everyone moved at once.
The tactical gear woman crossed to Kairo in about four steps. She looked at him, at the empty intersection, back at him, and she had the expression of someone whose entire framework for the situation had just been quietly dismantled.
"It closed," she said.
"Clearing the floor closes the gate," Kairo said. "Makes sense."
"We didn't know that would happen?"
"Nobody did," he said. "Now they do."
She stared at him. Then at Yuki still on his back, perfectly settled, watching the spot where the gate had been with an expression that was hard to read — something between relief and something that went deeper than relief.
"How long were you in there?" the woman said.
"About four minutes total. Twenty-three seconds for the crawler."
She went very still.
Around them the crowd had erupted, phones still raised, news drones closing in, officers doing the thing people do when something happens that none of their training covered. The delivery driver had sat down on the kerb and was staring at the empty intersection with the expression of someone mentally rewriting the last hour of their life.
Kairo looked at him. "Let them check you over."
The man looked up at Yuki. "Thank you," he said sincerely. "Both of you." A pause. "Can I at least know your names?"
Yuki opened her mouth.
"No," Kairo said.
She closed it. Looked at the side of his face. He was already turning away from the crowd, from the cameras, from the tactical gear woman who still hadn't managed to form a complete sentence.
Yuki stayed on his back as he walked and the crowd parted in that particular way it parted when it wasn't entirely sure what it had just witnessed.
Two blocks away she spoke.
"I wanted to tell him my name," she said.
"I know."
"It was a nice moment?"
"It was a moment where footage of us is being uploaded to every platform and you were about to attach a name to our faces."
She considered this. "That's fair." A pause. "You're still not as cool as you think you are."
"I don't think I'm cool."
"That's what makes it worse," she said.
He said nothing. The ramen place was on the next block, small, six seats, the kind that had been there longer than either of them had been alive.
"I want ramen," she said.
"I know."
"What if I hate it?"
"Then we try something else."
"You're not going to tell me I'll definitely like it?"
"I have no idea what you like. You've never eaten anything."
"That's a terrifying sentence?"
"You'll be fine."
She rested her chin more firmly on his head and he could feel her looking around at the street, at the sky, at all of it.
"Kairo," she said.
"Mm."
"I'm glad the gate was near our building."
He walked them toward the warm light coming through the ramen place's small window.
"Me too," he said.
She didn't say anything else.
Neither did he.
