The next day felt normal.
Almost too normal.
---
Classes continued.
Teachers lectured.
Students took notes.
Nothing unusual.
---
Which was exactly why Izuya noticed it.
---
"Something's off," he muttered quietly.
---
Ophelia, sitting one row ahead, turned around immediately.
"What is?"
---
Izuya rested his chin on his hand.
"…Too quiet."
---
She stared at him.
"This is a classroom."
"Yes."
"So it's supposed to be quiet."
---
Izuya didn't respond.
Because that wasn't what he meant.
---
It wasn't the sound.
It was the pattern.
---
He closed his eyes briefly.
---
Inside the Void—
The classroom reconstructed instantly.
Students appeared in their seats.
Teacher at the front.
Sunlight through the windows.
---
He replayed the morning.
Step by step.
---
Teacher enters.
Lecture begins.
Students respond.
---
Normal.
---
Again.
---
Something small.
Almost invisible.
---
A delay.
---
Izuya stopped the simulation.
Focused.
Replayed it again.
---
There.
---
Two students near the back.
They reacted half a second later than expected.
Not random.
Consistent.
---
"…Why?" he murmured.
---
The Azure Bird appeared on a desk nearby.
Watching.
---
Izuya frowned slightly.
---
Back in reality, his eyes opened.
---
Ophelia was still staring at him.
"Well?"
---
"…Nothing important."
---
She narrowed her eyes.
"That means it's important."
---
Sakura, sitting beside him today, glanced between them.
"What did you notice?" she asked quietly.
---
Izuya hesitated.
Then said:
"…Behavior lag."
---
Ophelia blinked.
"…What?"
---
"Some students are reacting slightly slower than they should."
---
"That's your problem?" she said.
---
"Yes."
---
She leaned back in her chair.
"You're insane."
---
Sakura didn't dismiss it.
"Is it intentional?" she asked.
---
Izuya didn't answer.
Because that was the problem.
---
He didn't know.
---
---
Lunch break.
---
The courtyard was louder than usual today.
More conversations.
More attention.
---
Izuya walked slightly away from the main crowd.
Same as always.
---
But this time—
he wasn't alone.
---
Sakura followed him.
Not closely.
Not obviously.
Just… there.
---
Ophelia joined a moment later.
"You two are boring," she said.
---
Izuya sat on the same bench as yesterday.
"…Okay."
---
Ophelia dropped down beside him again.
"You've been weird since morning," she said.
---
"Normal."
---
"No, even more than normal."
---
Sakura sat on the other side.
"What did you mean by 'behavior lag'?" she asked.
---
Izuya looked at the ground.
"…Timing differences."
---
"Explain."
---
He picked up a small pebble and rolled it between his fingers.
"People react based on patterns."
---
Sakura nodded slightly.
---
"If something changes," Izuya continued, "even slightly, the pattern shifts."
---
Ophelia frowned.
"And?"
---
"And something shifted."
---
A pause.
---
Sakura spoke softly.
"You think someone is influencing behavior?"
---
Izuya didn't answer.
---
But his silence was enough.
---
---
Across the courtyard—
Arthur stood near the same spot as yesterday.
---
Watching.
---
Not openly.
Not obviously.
---
But carefully.
---
In his hand was a phone.
On the screen—
a simple interface.
---
A school network panel.
---
Nothing illegal.
Nothing obvious.
---
Just access.
---
Arthur tapped once.
---
Across the campus—
small notifications were sent.
---
Schedule adjustments.
Minor changes.
Subtle variations.
---
Nothing major.
Nothing noticeable.
---
Except—
---
for someone like Izuya.
---
Arthur looked up.
His eyes found the bench.
---
"…So you noticed," he said quietly.
---
A faint smile appeared.
---
"Good."
---
---
Back at the bench—
Izuya suddenly stopped moving.
---
The pebble slipped from his fingers.
---
"…It's deliberate," he said.
---
Ophelia leaned forward.
"What is?"
---
Izuya looked toward the main building.
---
"…Someone is changing the pattern."
---
Sakura followed his gaze.
---
And for the first time—
her expression wasn't just calm.
---
It was serious.
---
"Who?" she asked.
---
Izuya didn't answer immediately.
---
Because he already knew.
---
Across the courtyard—
Arthur Beaumont stood under the sunlight.
Perfectly still.
---
Watching.
---
Izuya looked at him.
---
"…Troublesome," he muttered.
---
The Azure Bird appeared in his mind for just a second.
Wings slightly tense.
---
And for the first time—
the quiet of his world didn't feel peaceful.
---
It felt…
disturbed.
