The gate had closed behind Rika, but the feeling of the city had not.

It lingered on her clothes, in the damp weight of the mop in her hand, in the way her eyes kept moving even after the walls of the estate cut the outside world away. The others noticed it, even if none of them said so. She carried the city in with her—not its streets or its noise, but its pressure. The knowledge that one bad sound, one weak point, one stupid mistake could undo everything faster than people liked to believe.

The estate held itself differently.

It was not safe. Rika knew that the same way she knew a floor was dirty before she knelt to scrub it. Safe places invited carelessness. This wasn’t that. It was controlled. Ordered. Watched. The paths were clear. The doors closed properly. The air didn’t smell like rot and hot pavement and panic. It smelled like old wood, dust, faint cleaning chemicals, and somewhere under that, the soft green breath of plants drifting in from the grounds.

That was enough to matter.

Shizu led her into the house without ceremony. Rei stayed near enough to react if something happened, racket low at her side, shoulders set in that tense athletic stillness Rika recognized immediately. Not from school, not exactly. From the type of people who always seemed ready to move even when standing still.

Yumi appeared once at the edge of the hall holding a cable and a screwdriver, took one quick look at Rika, and said, “Good. Another person who looks like she knows how to hold a stick,” before vanishing back toward whatever she had been taking apart or improving.

Rika watched her go.

“That one always like that?” she asked.

Rei gave the smallest shrug. “Seems to be.”

Shizu didn’t turn around. “She’s useful.”

That sounded less like praise than acknowledgment.

Rika respected that.

They passed through a long hallway lined with dim portraits and furniture too heavy to move in a hurry. Nothing in the house looked abandoned. Unused, maybe. Waiting, definitely. But not abandoned. Whoever had maintained this place before the world broke had done so with care. Whoever was doing it now had not let that habit die.

That part belonged to Shizu. It was obvious almost immediately.

Not because anyone said it.

Because things were where they should be.

A lamp with fresh oil. A folded cloth left near a basin. A corridor runner straightened after being disturbed. The details didn’t matter until they did. Rika noticed them all. They told her more about the girl in the maid dress than any introduction would have.

“How many doors open to the outside?” Rika asked.

Shizu answered without slowing. “More than I like.”

“How many are still usable?”

“Enough.”

Rika let that sit for a beat. “Locked?”

“The important ones.”

That was probably the closest thing to reassurance she was going to get.

They entered a side room just off what might once have been a sitting room or family parlor. Now it had become what surviving people always turned rooms into once the original purpose stopped mattering: a place to gather, set things down, think, and leave again quickly if they had to.

There was water on the table. A lantern turned low. A pile of folded blankets in one corner. A chair pulled near the window, not for comfort but for line of sight. Two backpacks rested beneath a sideboard. A tennis bag lay against one wall with the zipper half open. On the mantle sat a flashlight, batteries, and a kitchen timer.

Useful things. Reachable things.

No one had named the room what it had become, but the room knew.

Shizu poured water into a glass and set it down. Then another. Then a third. She hesitated before the fourth, glanced at Rika’s hands, the grime on her sleeves, the exhaustion she was not showing, and set down one more without comment.

Rika took that one.

It was clean water. Cold enough to feel real.

She drank half in one go and stopped herself from finishing it.

Rei stayed standing near the doorway. “You can sit.”

Rika looked at her. “I’m fine.”

Rei nodded like that was the answer she expected.

No one pressed.

That part was good too.

For a while the room held its own kind of silence—not awkward, not friendly. A silence of measuring. Each of them taking stock of the newest variable in the house. Rika understood that. She did the same thing. Shizu knew the rooms. Rei knew where to stand. Yumi, wherever she was, knew the wiring. The estate had function because everyone in it had attached themselves to one.

That was something.

Not enough.

But something.

Rika set the glass down. “How many of you are here?”

Shizu answered. “Three.”

A beat.

“Now four.”

Rika nodded once.

No names. No backstories. No one asking where she’d been or how she got here. That restraint sat better with her than comfort would have.

From down the hall came a metallic clatter followed immediately by Yumi’s voice.

“No, no, no, you do not get to die on me now.”

Rei closed her eyes briefly.

Rika looked toward the doorway. “That sounds bad.”

“It usually isn’t,” Rei said.

“That’s not comforting.”

“It’s not supposed to be.”

A second later Yumi appeared in the doorway carrying a loose breaker switch in one hand and a flashlight in the other. She looked at Rika, then at the water glass in front of her, then at the mop still within easy reach of her chair.

“Okay, cool,” Yumi said. “You’re the practical one.”

Rika stared at her.

Yumi pointed the flashlight like she was making a serious observation. “Shizu’s the organized one. Rei’s the sports murder one. I’m the electricity one. You’re giving practical.”

Rei looked tired already. “Can you not do this right now?”

“Do what? I’m categorizing. Categorizing is how civilization survives.”

Shizu, from across the room: “Did you fix it?”

Yumi held up the switch. “Temporarily.”

“That means no.”

“That means yes, but with personality.”

She looked back at Rika. “You got a name?”

Rika considered not answering.

“Rika.”

Yumi nodded as if confirming a bet no one else knew she’d made. “Yeah, that fits.”

Then she was gone again, leaving the faint smell of dust and warm circuitry behind her.

Rika looked at the doorway she had vanished through. “How is she still alive?”

Shizu answered this time. “Adaptability.”

Rei, after a beat: “And luck.”

“No,” Shizu said calmly. “Luck would have failed her by now.”

Rika almost smiled at that.

Almost.

Outside, something scraped faintly along the far edge of the grounds.

Every person in the room heard it.

Rei’s head turned first. Not dramatically. Just enough.

Shizu set down the cloth she had been folding.

Rika didn’t move at all.

The sound came again. Soft. Irregular. Not close enough to threaten the room, only close enough to remind them that walls and windows did not erase what was outside.

“North side fence,” Shizu said.

“You can tell from that?” Rika asked.

“It catches there when something brushes it.”

Rei shifted her grip on the racket. “I’ll check.”

Rika looked at the hallway, then at Shizu. “No.”

Rei’s eyes narrowed slightly. Not offended. Not used to being stopped.

Rika stood. “Shizu knows the grounds best?”

Shizu gave a small nod.

Rika looked at Rei. “Then Shizu checks it. You cover her.”

That was all.

No buildup. No authority in the wording. Just the cleanest answer to the moment.

For half a second, no one moved.

Then Shizu picked up the lantern from the table.

Rei fell into step beside her.

And that was that.

Rika noticed the shift because she would have noticed it anywhere. In a laundromat. In a supply closet. In a room full of strangers who had run out of better options. Once the right thing had been said, everyone else adjusted around it.

She filed that away and followed at a distance.

The corridor opened onto a side entrance looking out over the rear grounds. Through the glass, the estate changed shape. Inside, it was dim and warm and old. Outside, it was layered darkness broken by pale gravel paths and the skeletal shape of trees. Beyond that: hedges, a low stone wall, and farther off still, the suggestion of another structure sitting beneath the shadow of the grounds.

The greenhouse, Rika guessed.

Shizu eased the door open without a sound.

Rei moved just off her shoulder.

They stepped onto the stone.

Rika stayed inside the threshold, not because she was afraid to go farther, but because crowding the doorway would make all three of them worse at once.

Shizu raised the lantern.

The light touched a section of fence, the nearest hedge, a clay planter overturned beside the path.

Nothing else.

No rushing shape. No dead thing half-caught in the iron.

The grounds seemed to hold themselves very still around the edge of the light.

Rei took one step forward, then another. Her racket stayed low, ready to come up fast.

Shizu angled the lantern toward the north side.

There, near the fence, a branch moved slightly against the wire.

The sound came again.

A scraping, then a dry tap.

Wind. Or something that had passed and kept going.

Rei exhaled slowly through her nose. “That’s it?”

“For now,” Shizu said.

Rika looked past them toward the darker shape in the distance. “What’s that building?”

Shizu followed her gaze. “Greenhouse.”

“Anyone checked it?”

A pause.

Then Shizu said, “Not yet.”

That mattered more than she liked.

Rika let it go for now. One unknown at a time.

They came back inside and secured the door again.

Nothing more hit the fence.

Nothing rattled the glass.

But the house no longer felt like it was pretending. It had settled into what it really was: a held position. Not a refuge. Not a fortress. Just a place that still had walls, power, and enough people paying attention to keep it from failing all at once.

Later, they ended up in the kitchen because every house, no matter how grand, eventually reduced itself to its most practical room. Yumi arrived with a coil of wire around one wrist and announced that the game room could power two more lamps if nobody got “stupid with the outlets.” Rei took the first watch position near the rear corridor without discussion. Shizu counted canned goods under her breath while rearranging a shelf that had probably not needed rearranging until she touched it.

Rika sat at the table with the mop resting against her knee and watched them become legible.

Shizu protected the shape of things.

Rei protected the edges.

Yumi protected whatever could still be made useful.

And her?

Rika looked down at her hands.

She had always cleaned up what happened after people stopped thinking clearly.

Maybe that was all this was.

Maybe that was enough.

No one talked about sleeping, though blankets had been gathered and lights lowered. Outside, the estate made its quiet noises: leaves shifting, wood settling, the distant hum of the generator threading through the walls like a second heartbeat. Somewhere beyond the rear grounds, something cried out once in the dark—too far away to matter immediately, too close to ignore entirely.

Rika stayed awake longer than the others expected and less visibly than they noticed.

Rei remained by the window with the red racket resting across her shoulder.

Shizu moved through the room one last time, checking latches with a kind of absent precision that suggested the motion was as natural to her now as breathing.

Yumi disappeared, reappeared with a wrench, disappeared again.

The house held.

That, more than anything, felt temporary.

The sound came just past midnight.

Not from the fence.

From the side window near the service hall.

A faint scrape.

Then stillness.

Rei was on her feet before the second sound arrived.

Knock.

Light. Careful. Barely more than the touch of fingernails or knuckles against glass.

No one spoke.

A third sound followed after a pause.

Not wandering.

Not dragging.

Intentional.

Rika stood.

Shizu turned toward the darkened pane.

Rei shifted her stance, racket raised slightly now.

The shape beyond the window remained mostly shadow, still and waiting just outside the weak spill of indoor light.

Another knock.

Quiet.

Measured.

Like whoever made it wasn’t sure they should be there at all.
