The clap came again.
Once.
Slow.
Measured.
Not the sound of someone impressed.
The sound of someone confirming that reality had finally arranged itself into a readable pattern.
No one in the station moved first.
That was wise.
The broken roof above them held moonlight in fractured lines, and through one of those lines Kaito saw him—not fully at first, only the outline of a man standing where the roof had collapsed inward, hands visible, posture unhurried, as if he had entered a negotiation room rather than the ruined center of a hidden war.
Morita Ren.
Not masked.
Not armored.
Not dressed like Root in any ordinary field sense.
He wore layered dark civilian-black with travel dust on the hem and one narrow archive cord wrapped twice around his left wrist. No insignia. No dramatic weapon. No visible threat except the kind that learns to survive by making threat look administrative rather than personal.
Kaito hated him immediately.
Not because he was ugly.
Because he looked like someone who would apologize while erasing a person's existence from the world and genuinely believe the apology proved moral refinement.
Morita's gaze found the room quickly.
Serou first.
Then Yukari.
Then Kanai.
Then Sato.
Then Eizan.
He left Kaito for last.
That, more than the clap, was the first real attack.
Not because it diminished him.
Because it announced:
I have already built the order of importance in my head.
Morita inclined his head very slightly.
"Interesting."
No one answered.
Good.
Morita's eyes moved to the open drawer beneath the central desk, then to the slips already in Yukari's hand, then finally to the broken comparison weight still resting in the ash-dark compartment.
"Ah," he said softly. "You found the honest part of the room before the false part won."
That sentence changed the station.
Because only someone who understood the station deeply would phrase it that way.
Not the safe part.
Not the useful part.
The honest part.
Yukari's voice went cold.
"You've been here before."
Morita looked at her with a kind of professional courtesy Kaito instantly distrusted.
"Yes."
"No," Kanai said from the wall, pale and half-breathless but still sharp enough to cut. "Say it properly."
Morita's eyes shifted to him.
Kanai's mouth twisted faintly.
"You crawled through what better minds left half-burned and taught yourself to call that scholarship."
For the first time, Morita smiled.
Not warmly.
Not with offense.
With appreciation.
"That," he said, "is very nearly fair."
Kaito felt the seal in his wrist go cold again.
Not because Morita had attacked.
Because the man's language itself tried to settle into legitimacy.
Very nearly fair.
No.
Nothing about him was fair.
Serou stepped half a pace toward center, just enough to remind the station that not every line in the room would remain abstract and polite if forced too far.
"You spoke," Serou said, "so either you think you are safe here, or you think language will buy you something."
Morita looked at him with open interest now.
"Both, perhaps."
Eizan made a dry sound.
"There he is."
Morita's gaze flicked briefly to the older keeper.
"You're still alive too. That is becoming a pattern I should have corrected sooner."
No one liked how mildly he said that.
Sato's voice cut cleanly through the room.
"What do you want?"
Morita turned toward her, and for one brief second the courtesy in his face thinned enough for the thing beneath it to show.
Not rage.
Not cruelty in the theatrical sense.
Appetite for resolution.
"I want," he said calmly, "the same thing everyone in this room wants. A correct reading."
"No," Yukari said.
Morita looked at her.
"Yes."
"No," she repeated, sharper now. "You want a usable reading."
That made the smile vanish.
Good.
There he is, Kaito thought.
Morita answered without softness.
"Usable is the only form of correct that survives institution."
Silence.
There it was.
Clean.
Unadorned.
The philosophy.
Not truth.
Not personhood.
Not witness.
Not choice.
Usability.
Kaito felt something settle in him then.
Not outrage.
Not surprise.
Certainty.
Morita Ren was not merely the opposite of Kimi in method.
He was the opposite of Kimi in ontology.
Kimi built systems to prevent ownership from completing itself through force.
Morita believed any truth that could not survive use deserved to be rewritten until it could.
Serou said quietly, "Then you and I do not mean the same word when we say 'correct.'"
Morita's eyes remained calm.
"I know."
Kaito noticed then that Morita still had not stepped fully into the room.
Interesting.
Not fear.
Not caution in the usual sense.
Respect for comparative spaces.
Or perhaps distrust of them.
He asked the question before anyone else could spend the next minute circling it.
"Why are you really here?"
Morita turned to him fully at last.
The station felt that.
Kaito felt that.
Everyone did.
The man's answer came with no wasted sound in it.
"To confirm whether your refusal is structural… or merely emotional."
That landed hard.
Because it was the right question for a man like Morita.
If Kaito's recent interferences with Desk Nine had been only instinct, rage, or anomaly, then they could still be modeled around.
If they were structural—
then Root's whole approach would need to change.
Kaito looked at him and said, "You came for an answer from me."
Morita's eyes sharpened faintly.
"No."
A pause.
"I came to see whether the answer is stable enough to survive witness."
That was worse.
Because it meant Morita was not just studying Kaito anymore.
He was studying the relationship between Kaito and Yukari.
The same line Kimi had preserved.
The same line the packet activated.
The same line the station comparison slips had almost named.
Yukari saw it too.
Her voice lowered by one dangerous degree.
"You should have stayed ignorant."
Morita's expression did not change.
"I tried that once." He glanced at the slips. "Your dead friend was very inconsiderate about ignorance."
Kanai laughed once despite the pain, and this time it sounded like blood trying to become a joke.
Morita looked at him.
"You should be dead."
Kanai answered at once.
"You should be less curious."
Morita considered that.
Then said, very calmly,
"Curiosity is not my failing."
His gaze returned to Kaito.
"Premature mercy is."
The station went cold.
That sentence was not aimed at the room generally.
It was aimed precisely where Morita believed the fault line now lived:
in the space between Kaito's refusal and Yukari's witness.
Mercy.
Witness.
Choice.
Delay.
All the things Kimi had used to deny power its cleanest path.
Morita saw them not as virtues.
As inefficiencies.
Kaito stepped once toward center.
Not enough to cross into recklessness.
Enough to answer presence with presence.
The seal in his wrist tightened—not recoiling, not inviting, only sharpening.
He asked quietly,
"And if you get your correct reading?"
Morita's answer came without hesitation.
"Then I will prevent the world from wasting you."
No one in the room misunderstood what that meant.
Not rescue.
Not protection.
Not even capture in the crude sense.
Conversion.
Kaito looked at him and, for the first time since Morita arrived, let a little of the truth into his voice.
"You think that sounds kind."
Morita held his gaze.
"No," he said.
And that answer, somehow, was worse than if he had lied.
Because it meant he knew exactly what he was.
Then the broken comparison weight in the drawer clicked once by itself.
Everyone turned.
Not enough movement to activate.
Not enough to complete anything.
Only enough to say:
this room has heard both sides now.
Morita's eyes shifted toward the drawer.
Then back to Kaito.
And for the first time, something in his calm sharpened into actual interest.
"Ah," he said softly.
"The room likes you more than it should."
Then, from beyond the broken rear wall, three black paper lines rose from the ash-dark floor at once.
And Morita did not turn to look.
Which meant he had not come alone.
