The disturbance didn't stop.
---
By the next morning—
it had grown.
---
Not louder.
Not obvious.
---
Just… deeper.
---
Izuya noticed it the moment he stepped into the school gate.
---
Students moved normally.
Talked normally.
Laughed normally.
---
But the timing—
was wrong.
---
Someone dropped a pen.
The reaction came a fraction too late.
A group laughed—
but not at the same time.
A teacher called a name—
the response lagged.
---
Tiny delays.
Everywhere.
---
Invisible to most.
---
But not to him.
---
"…It spread," Izuya murmured.
---
He didn't go to class immediately.
Instead, he stopped near the courtyard.
Watching.
Analyzing.
---
Inside his mind—
the Void activated without him closing his eyes.
---
The school appeared.
Students became moving data points.
Every action.
Every reaction.
Every delay.
---
He mapped it.
---
Points of disruption.
Clusters.
Patterns.
---
"…Not random," he said quietly.
---
The Azure Bird circled above.
---
Izuya traced the pattern further.
---
The delays weren't equal.
They weren't everywhere.
---
They were concentrated.
---
Around specific areas.
---
Corridors.
Classrooms.
Common zones.
---
Connected by something.
---
"…Network," he realized.
---
Back in reality, his eyes sharpened slightly.
---
"…School system."
---
---
Class 2-B.
---
Izuya entered late.
Not that anyone was surprised.
---
Ophelia turned immediately.
"You look like you didn't sleep."
---
"I did."
---
"You look worse than usual."
---
"Probably."
---
Sakura watched him carefully.
"You found something."
---
Izuya sat down.
"…Yes."
---
"What?" Ophelia asked.
---
He placed his bag down slowly.
---
"The pattern isn't human."
---
A pause.
---
Sakura's expression changed slightly.
"…Meaning?"
---
"External influence," Izuya said.
---
Ophelia blinked.
"Speak normal language."
---
Izuya sighed.
"…Someone is using the school system to manipulate behavior timing."
---
Silence.
---
Ophelia stared at him.
"…That's not normal."
---
"No."
---
Sakura leaned slightly closer.
"Can you trace it?"
---
Izuya paused.
---
"…Yes."
---
A small pause.
---
"…But it's annoying."
---
Ophelia groaned.
"Everything is annoying to you!"
---
---
Lunch break.
---
Izuya didn't go to the courtyard.
---
Instead—
he went to the computer lab.
---
Empty.
Quiet.
Perfect.
---
He sat down at one of the systems.
Turned it on.
---
The screen lit up.
---
School network access.
Restricted.
---
Izuya stared at it for a few seconds.
---
"…Okay."
---
His fingers moved.
---
Fast.
Precise.
---
Not aggressive hacking.
Not forceful.
---
Just… slipping through.
---
Like he belonged there.
---
Inside the Void—
time expanded.
---
Ten hours.
Twenty.
Thirty.
---
Firewalls appeared.
He walked around them.
Security layers formed.
He stepped past them.
---
Not breaking.
---
Understanding.
---
"…You left it open," he murmured.
---
The system unfolded.
---
Access granted.
---
Back in reality—
only ten minutes had passed.
---
Izuya leaned back slightly.
---
"…Found it."
---
---
The data appeared.
---
System logs.
Automated triggers.
Behavioral nudges.
---
Tiny delays.
Inserted intentionally.
---
Not random.
---
Designed.
---
Izuya scrolled.
---
Then stopped.
---
A signature.
---
Not a name.
---
But a pattern.
---
Clean.
Efficient.
---
Familiar.
---
"…Of course," he muttered.
---
---
Elsewhere in the school—
---
Arthur stood near a window.
---
His phone buzzed once.
---
He looked at it.
---
A small notification:
Access detected.
---
Arthur's expression didn't change.
---
"…Faster than expected," he said quietly.
---
He locked the phone.
---
Then looked toward the direction of the computer lab.
---
"…So you chose to engage."
---
A faint smile appeared.
---
---
Back in the lab—
---
Izuya stared at the screen.
---
He could shut it down.
Easily.
---
He could remove the interference.
Restore normal patterns.
---
Return everything to quiet.
---
His fingers hovered over the keyboard.
---
Then—
stopped.
---
"…No."
---
He leaned back.
---
"If I stop it…"
---
He looked at the data again.
---
"…I learn nothing."
---
The Azure Bird appeared beside him.
Still.
Watching.
---
Izuya closed his eyes briefly.
---
"…So this is your method," he murmured.
---
---
When he opened them again—
---
his expression had changed slightly.
---
Not much.
---
But enough.
---
For the first time—
---
he wasn't avoiding the disturbance.
---
He was looking at it directly.
---
---
In the hallway outside—
---
Sakura stood quietly.
---
She had followed him.
Not all the way.
Just enough.
---
She didn't enter.
---
But she waited.
---
Ophelia arrived a moment later.
"Is he in there?"
---
Sakura nodded.
---
"…He's different today," she said softly.
---
Ophelia crossed her arms.
"Yeah."
---
A pause.
---
"…More alive."
---
---
Inside the lab—
---
Izuya looked at the screen one last time.
---
"…Fine," he said quietly.
---
Then he closed the system.
---
Stood up.
---
And walked out.
---
---
Across the building—
---
Arthur watched the hallway as Izuya stepped out of the lab.
---
Their eyes met again.
---
No distance this time.
---
No crowd.
---
Just a straight line between them.
---
Arthur spoke first.
---
"You found it."
---
Izuya replied without hesitation.
---
"Yes."
---
A pause.
---
Then—
---
Arthur asked:
---
"Why didn't you stop it?"
---
Izuya looked at him.
---
"…Because you wanted me to see it."
---
Silence.
---
Then—
---
Arthur smiled.
---
Not politely.
---
Not formally.
---
Genuinely.
---
"Correct."
---
---
And just like that—
---
the game between them
was no longer hidden.
---
It had begun.
