The Alarm
The first scream came out of a piece of plastic.
It was thin and metallic, the kind of sound that didn’t belong in a Tokyo apartment building at midnight. It sliced through the hum of the air purifier and the distant hush of traffic, rising sharp enough to make Haruto’s teeth hurt.
For a heartbeat, Haruto didn’t move.
His body went into the same frozen place it had gone in the inn–the place where time thickened and the brain tried to decide whether the world was real. The scream kept going, relentless and high, turning his small room into a siren box.
Then his breath returned in a violent inhale.
He was on the futon. The room was dark except for the faint glow of the kitchen clock. The air smelled of detergent and the last traces of lotion on his skin. His palms were still pressed to his chest from the habit of it.
Flat.
Warm.
Alive.
The scream continued.
Haruto sat up so fast his head swam.
The alarm wasn’t in his room.
It was at the door.
The wedge.
The local-only piece Kaito had given him–metal and plastic, no cloud, no app, just noise.
Noise meant truth.
Haruto’s heart hammered so hard he could feel it in his fingertips.
He swung his legs off the futon and stood, bare feet meeting cold floor. His body shook–not from cold, from adrenaline. His mind flashed images too fast to form: door sliding open; shadow across tatami; a voice in his ear.
This was the first world.
This door was wood and metal.
This scream was real.
Haruto forced his gaze to the entryway.
The door didn’t move.
The chain lock didn’t rattle.
But the wedge was screaming like it had felt the door shift.
He took one step toward it.
Then he stopped.
Ito’s voice, calm as a knife, echoed in his head:
Do not investigate alone.
Haruto swallowed hard.
He backed away from the door.
The scream kept going.
His throat tightened.
He didn’t have his smartphone.
Only the loaner.
He stumbled to the table, grabbed the cheap phone with shaking fingers, and scrolled the whitelist list like it was scripture.
Emergency.
Security Ops.
Ito.
Kaito.
Aoi.
Mirrorhouse.
Haruto’s thumb hovered over Kaito.
Witness.
Procedure.
But Ito had been clear.
Emergency first.
Haruto pressed emergency.
The line rang.
Once.
Twice.
The scream from the door filled the gaps between rings.
A dispatcher answered.
“Emergency services,” a voice said, crisp. “What is your location?”
Haruto’s mouth was dry.
“My door alarm is going off,” he said, voice cracking. “I’m at–”
He forced himself to say his address clearly.
The dispatcher asked questions.
Is someone inside?
Did you see anyone?
Is your door locked?
Haruto answered, short, shaking.
“I’m alone. I didn’t open it. The chain is on. I hear… I don’t know.”
“Stay inside,” the dispatcher instructed. “Do not open the door. Officers are on the way.”
Haruto’s breath shook.
“Yes,” he whispered.
The dispatcher stayed on the line.
“Can you move away from the door?”
Haruto looked at the entryway.
The door was still.
The wedge still screamed.
“Yes,” he said. He backed deeper into the room until he could see the door from a distance but not feel it looming.
“Do you have any windows accessible?” the dispatcher asked.
Haruto glanced toward his window. Seventh floor. Street far below.
“No,” he said.
“Okay,” the dispatcher said. “Stay where you are. If you hear the door handle moving or the chain rattling, tell me immediately.”
Haruto swallowed.
His palms were slick.
The scream continued.
In the quiet between his heartbeats, he heard something else.
A soft scuff.
Not inside.
Outside.
Footsteps in the hallway.
Haruto’s blood went cold.
He tightened his grip on the loaner phone.
The dispatcher’s voice remained steady.
“I’m still here,” she said.
Haruto nodded even though she couldn’t see.
The footsteps outside paused.
Silence.
Then another sound.
A faint scrape near the door gap.
Paper?
A thin object?
Haruto’s stomach lurched.
The keyhole envelope sliding under.
His throat tightened.
He forced his voice out.
“I hear something outside,” he whispered.
“Stay back,” the dispatcher said immediately. “Do not approach the door.”
Haruto’s knees threatened to buckle.
He backed further until he pressed against the wall near the kitchen.
The scream kept going.
Then, abruptly, it stopped.
The sudden silence was worse.
It made the air feel empty and exposed.
Haruto held his breath.
The dispatcher spoke.
“Are you okay?”
Haruto swallowed.
“I– It stopped,” he whispered.
“That can happen,” the dispatcher said, calm. “Officers are close. Stay inside.”
Haruto’s eyes burned.
He waited.
His body felt like a taut wire.
Then the hallway filled with voices.
Not loud.
Professional.
A muffled male voice calling out.
“Police. Is the resident inside?”
Haruto’s throat tightened.
He stayed where he was.
The dispatcher instructed him to answer through the door without opening it.
Haruto moved slowly, every step cautious, as if the floor might betray him.
He approached the door until he could see the wedge under it.
The wedge sat there, quiet now, like nothing had happened.
Haruto’s stomach churned.
He kept his hand away from the handle.
“I’m inside,” he called, voice shaking.
“We’re outside your door,” the officer said. “Are you injured?”
“No,” Haruto said.
“Is the door locked?”
“Yes. Chain too.”
“Okay,” the officer said. “We’re going to check the hallway. Do you see anything on the floor inside your door gap? Any item slid under?”
Haruto’s breath hitched.
He looked down.
There was something.
A thin shape.
Half under the door.
A flat, dark rectangle like a letter.
His blood went cold.
“Yes,” Haruto whispered.
“Do not pick it up yet,” the officer said. “We’ll instruct you. First, confirm there’s no one in your unit besides you.”
Haruto swallowed.
He glanced around his one-room apartment.
Everything was where he left it.
No hiding places.
No closets that could hold a person.
“I’m alone,” he said.
“Okay,” the officer said. “We will keep the hallway secure. When we tell you, you’ll open the door with chain engaged, just enough to pass the item out. Understood?”
Haruto’s throat tightened.
“Yes,” he whispered.
Haruto heard more footsteps.
A second voice–building security, perhaps. His building manager’s irritated tone cut through.
“Nishimura-san? Are you okay?”
Hearing his name made his stomach twist.
He answered through the door.
“I’m okay,” he said, voice tight.
The officer gave instructions.
Haruto’s hands shook as he slid the chain latch open a fraction and pulled the door toward him just enough to create a narrow gap.
Cool hallway air slipped in.
Haruto’s nervous system flared at the boundary–door opening, gap widening.
He kept his gaze down.
The officer crouched outside, visible only as shoes and lower legs.
“Where is the item?”
Haruto pointed.
The officer used a gloved hand and a small tool–tweezers–to pull the rectangle through the gap.
Haruto watched the glove.
White.
Latex.
Powdered.
Something about it made his skin crawl.
Because he had seen gloves like that.
In the lab.
In the forensic room.
Not unique.
Common.
Yet in his body, common had become threatening.
The officer sealed the rectangle into an evidence bag.
“Okay,” the officer said. “You can close the door.”
Haruto closed it immediately.
Locked.
Chain.
He slid down the door and sat on the floor for a moment, breathing hard.
The dispatcher ended the call.
Haruto was alone again, separated from the hallway by wood.
But not by certainty.
A few minutes later, there was a knock.
Three short taps.
“Police,” the officer called. “We’d like to speak with you. Keep the chain on.”
Haruto swallowed.
He stood slowly and opened the door chain-first.
The hallway was full of bodies.
Two officers.
His building manager.
A security guard.
The fluorescent light made everyone look pale.
The officer’s eyes were professional, not unkind.
“Can you tell us what happened?”
Haruto’s mouth was dry.
He told them the truth he could tell in this world.
“My door alarm went off,” he said. “I didn’t open it. I heard movement outside. Something was slid under the door.”
The officer nodded.
“You’ve had incidents before?”
Haruto’s stomach tightened.
The building manager sighed.
“He called a few nights ago about something under the door,” the manager said.
Haruto wanted to disappear.
The officer’s gaze stayed steady.
“We checked the hallway cameras at the entrance,” the officer said. “We can see someone entered around 12:07. Hood up. Mask. They avoided the camera angle. We can’t identify the face.”
Haruto’s blood went cold.
Real.
Physical.
Not only code.
The officer continued.
“They moved toward your floor,” he said. “We can’t see inside your corridor. There’s no camera there.”
Privacy.
His manager’s earlier excuse.
Haruto’s chest tightened.
The officer held up the evidence bag with the rectangle inside.
“It’s an ID badge,” he said.
Haruto’s throat tightened.
Badge.
The officer flipped it inside the bag.
Plastic card.
A clip.
A lanyard string.
Printed on the badge was a logo.
Not Second World’s.
Not his building’s.
A contractor.
A third-party maintenance company name in small letters.
Haruto’s stomach dropped.
The officer’s voice remained neutral.
“It appears to be a contractor access badge,” he said. “Not for your building. Possibly for another facility. There’s also a sticker on the back.”
Sticker.
Haruto’s skin prickled.
The officer angled it so Haruto could see.
A tiny keyhole stamp.
Haruto’s blood went cold.
The officer’s eyes narrowed.
“Do you recognize this symbol?”
Haruto’s breath hitched.
He could lie.
He could pretend ignorance.
But procedure was the only thing keeping him from drowning.
Haruto swallowed hard.
“Yes,” he said. “It’s connected to… online vendors. Mods. The same mark was on other items.”
The officer nodded.
“Okay,” he said. “We’ll file this with the earlier report. This badge could be stolen, could be planted. But it’s a lead.”
A lead.
Haruto’s throat tightened.
The security guard spoke.
“We can have patrols check the corridors tonight,” he said. “But we can’t be on every floor all the time.”
Haruto’s chest tightened.
All the time.
That was what Ghostkey wanted–constant vigilance until you broke.
The officer looked at Haruto.
“Do you have anyone you can stay with?” he asked.
Haruto’s stomach dropped.
Stay with.
Home.
Mother.
Friends.
He didn’t have anyone close enough who wouldn’t ask questions he couldn’t answer.
“I… prefer to stay here,” he said quietly.
The officer nodded.
“Then we recommend you don’t open your door for anyone you don’t recognize,” he said. “Keep lights on. Consider installing a peephole camera. And call immediately if anything happens again.”
Haruto nodded.
The officer handed him a card.
A case number.
A name.
A phone number.
Haruto took it with shaking fingers.
The building manager shifted impatiently.
“I’ll see if we can install a corridor camera,” he said. “It will take approvals.”
Approvals.
Always approvals.
Haruto swallowed.
The officer’s gaze stayed on him a moment longer.
“Are you okay?” he asked.
Haruto almost laughed.
Okay.
The word that kept looping.
He nodded anyway.
“I’m okay,” he lied.
The officer didn’t push.
He nodded, then turned away.
The group dispersed.
Footsteps faded down the hallway.
The fluorescent hum remained.
Haruto closed his door.
Locked.
Chain.
He leaned his forehead against the wood.
His breath came shallow.
Then he realized something.
The intruder had not just tried the door.
They had left a badge.
A physical clue.
A contractor badge with a keyhole stamp.
And that meant the predator wasn’t only in his phone.
Not only in maintenance tokens.
Not only in the second world.
He was in the supply chain.
In the people who wore lanyards.
In the hallways of buildings like Second World HQ.
Haruto’s stomach turned.
His hands shook.
He crossed the room and picked up the loaner phone.
He scrolled to Ito.
Whitelisted.
Verified.
He called.
The phone rang once.
Ito answered.
“Nishimura-san,” she said, voice crisp.
Haruto’s throat tightened.
“Someone came to my door,” he said. “They tried something. Police came. They took what was slid under. It was… a contractor badge. With the keyhole stamp.”
Silence on the line.
A short, dangerous silence.
Then Ito’s voice sharpened.
“Are you safe right now?”
Haruto swallowed.
“Yes,” he whispered. “Door locked. Chain.”
“Good,” Ito began, then caught herself. “Stay inside,” she said. “Do not touch any items. Do not handle evidence. The police have it?”
“Yes,” Haruto said.
Ito exhaled.
“Tell me the contractor name,” she said.
Haruto swallowed.
He didn’t have the badge.
But he had seen the logo.
He described it as best he could.
Ito went quiet again.
Then she spoke, voice low.
“That contractor provides facilities maintenance for multiple tech firms,” she said. “Including–”
She stopped.
Haruto’s blood went cold.
“Including what?” he whispered.
Ito exhaled.
“Including us,” she said.
Haruto’s stomach lurched.
The badge.
A maintenance contractor.
The maintenance token.
The spoofed maintenance prompts.
It lined up like teeth.
Ito continued, voice controlled.
“I’m escalating this immediately,” she said. “This is no longer only in-platform harassment. This is physical stalking with a possible link to our vendor ecosystem.”
Vendor ecosystem.
Haruto’s throat tightened.
Ito added, softer:
“Nishimura-san, do you have anyone with you?”
Haruto swallowed.
“No,” he whispered.
Ito’s voice tightened.
“I don’t like that,” she said. “We can arrange temporary relocation through a safety partner. A hotel. Anonymous booking. Would you accept that?”
Hotel.
A new room.
A new door.
Haruto’s nervous system flared.
Hotels were corridors.
Doors.
Unknown hallways.
He swallowed hard.
“I don’t know,” he whispered.
Ito’s voice softened.
“Okay,” she said gently. “Then at minimum, we’ll increase building security patrols if possible. And I want you to keep the door wedge alarm active. If it triggers again, call emergency immediately. Do not open.”
Haruto nodded.
Ito continued.
“I’m also scheduling you for a supervised Mirrorhouse session tomorrow morning,” she said. “You’ll need grounding after this.”
Grounding.
Breath.
Haruto’s throat tightened.
“Thank you,” he whispered.
Ito exhaled.
“Try to sleep,” she said. “Even if you don’t feel sleepy. Lie down. Breathe. Keep a light on if you need. We will contact you with next steps.”
Haruto swallowed.
“Okay,” he whispered.
Ito echoed.
“Okay.”
She hung up.
Haruto stood in his kitchen with the loaner phone in his hand, the air purifier humming, the city’s distant noise seeping through glass.
He looked at the door.
The wedge alarm sat under it, quiet and ready.
He looked at the evidence bag on his table.
Mirror strip.
Card.
Perfume bottle.
Cloud sensor.
Now there was a new evidence item somewhere in police custody:
A contractor badge stamped with a keyhole.
A clue that was too clean.
Too designed.
Because predators didn’t only attack.
They curated.
They left marks.
They wanted you to know they could walk the same hallways as the people you thought could protect you.
Haruto’s chest tightened.
He sat on the futon and pressed both palms to his chest.
Flat.
Warm.
Alive.
His body shook.
He closed his eyes.
In the dark, he saw Mirrorhouse’s corridor of mirrors.
Reina reflected back.
Not bait.
Not a wound.
Breath.
He remembered warm water holding her.
Witnesses saying witnessed.
A stop word that worked.
He whispered, barely audible:
“Stay.”
His eyes opened.
The loaner phone lit up.
A call.
Whitelisted.
Kaito.
Haruto’s stomach tightened.
He hadn’t called Kaito.
Ito hadn’t said she would.
Yet Kaito was on the whitelist.
A witness.
A door.
Haruto stared at the screen for a beat too long.
Then he answered.
“Kaito,” he said.
Kaito’s voice came through, low and urgent.
“Ito told me,” he said. “About the door. About the badge. Are you okay?”
Okay.
Haruto’s throat tightened.
“I’m alive,” he said.
Silence on the line.
Not awkward.
Heavy.
Kaito exhaled.
“I’m coming,” he said.
Haruto’s stomach dropped.
“No,” he said quickly. “Don’t. Ito said–”
Kaito cut in, voice calm.
“I’m not coming to your door,” he said. “I’m coming to your building lobby. Public. Security guard. Cameras. I’ll stand there for ten minutes. If you need to leave, you’ll have a witness. If you don’t, I’ll go.”
Procedure.
Haruto’s breath hitched.
He hated how much the offer soothed him.
He hated that he might need it.
He swallowed.
“Don’t come upstairs,” Haruto said, voice tight.
“I won’t,” Kaito promised.
Promises.
Haruto didn’t trust promises.
He trusted boundaries.
He nodded anyway, even though Kaito couldn’t see.
“Okay,” Haruto whispered.
Kaito echoed softly.
“Okay.”
The call ended.
Haruto sat with the silence.
His apartment felt too small.
The door felt too near.
His body felt like it was vibrating with afterimage, with adrenaline, with exhaustion.
He lay back on the futon and stared at the ceiling.
His breathing was shallow.
He forced it deeper.
Lift breath.
Dr. Saeki’s instruction.
He tried to let the breath sit higher.
He whispered his name–Haruto–once, then again, softer.
The sound shifted a hair.
Not enough to change his life.
Enough to remind him he could still choose.
Outside, the building’s hallway was quiet.
No more footsteps.
No more scraping.
But Haruto’s mind kept returning to the badge.
Maintenance contractor.
Keyhole stamp.
A deliberate link between the second world’s internal tokens and the first world’s physical corridors.
If the badge had been left as a clue, it meant the predator wanted him to look there.
To suspect.
To spiral.
To contaminate trust.
And if the predator wanted him to suspect everyone, then the safest thing Haruto could do was the hardest:
Trust only what could be verified.
Witnesses.
Receipts.
Logs.
Chain of custody.
Not feelings.
Not flinches.
Not the warmth of relief when someone stood close.
Haruto closed his eyes.
He pressed both palms to his chest.
Flat.
Warm.
Alive.
He whispered, voice barely audible:
“Not a door.”
And in the darkness, as sleep finally approached like a cautious animal, one last thought tightened around his heart like a ribbon:
The badge could have belonged to anyone.
But the hand that chose to leave it–
that hand knew exactly what would make him afraid.
