The next phase began without warning.
No preparation.
No explanation.
Only a command.
"All students, assemble."
The voice echoed across the training grounds.
Sharp.
Absolute.
Rei and Airi moved instantly.
No hesitation.
No wasted motion.
The field reorganized itself in seconds.
Students gathered into rows.
Pairs stood side by side—some natural, some forced.
The structure felt different.
Heavier.
Rei noticed it immediately.
"…They're removing flexibility," she said.
Airi stood beside her.
"…Meaning?"
"No adjustments," Rei replied.
"No corrections mid-task."
A pause.
"…So if something goes wrong…"
"It remains wrong."
Silence.
The instructor stepped forward.
"This phase will test synchronization."
Murmurs spread instantly.
"Each pair will complete a series of coordinated tasks."
A screen activated behind him.
Scores.
Visible.
Public.
Every student's name.
Every pair's performance.
No concealment.
"Failure to synchronize will result in score penalties."
A pause.
"Severe penalties."
The weight of it settled over the field.
Rei's gaze shifted slightly.
"They're forcing dependency," she said.
Airi's chest tightened.
"…Even more than before."
"Yes."
But there was more.
Rei had already seen it.
The pairings had changed again.
"Kanzaki Airi."
Airi stepped forward.
"Partner: confirmed."
The same girl from Class C stepped into position beside her.
No surprise.
No reaction.
Only intent.
Rei watched.
Deliberate repetition.
The system was reinforcing the variable.
"Rei."
Her name was called next.
"Independent observation unit."
Silence.
Airi turned slightly.
"…You're not assigned?"
"No."
Rei's eyes narrowed.
"They're isolating my influence."
A pause.
"…Then what do we do?"
Rei looked at her.
"You perform."
Simple.
Absolute.
Airi nodded.
"…Understood."
The whistle blew.
Phase one.
Mirror movement.
Each pair had to replicate a sequence of motions perfectly.
Any deviation—
Penalty.
Airi stepped into position.
The girl beside her moved first.
Fast.
Too fast.
Deliberate.
Airi adjusted instantly.
Not reacting—
Predicting.
The movements aligned.
Not perfectly.
But close.
The system registered the result.
Score: 82%
Murmurs spread.
High.
Given the interference.
The girl glanced at Airi.
"…You're better than expected."
Airi didn't respond.
Her focus remained forward.
Rei observed from a distance.
No intervention.
Only analysis.
Adaptation speed increased.
Phase two began immediately.
Balance coordination.
A narrow beam.
Two students.
One path.
Airi stepped onto the beam.
The girl followed.
Too close.
Intentional pressure.
Airi felt it.
The instability.
The shift in weight.
One mistake—
And both would fall.
Her breath slowed.
Focus.
Not on the pressure.
On the center.
The balance point.
She adjusted her stance.
Reduced external influence.
Controlled her own movement.
The girl increased pressure.
A test.
Airi didn't react.
She compensated.
Step by step.
They reached the end.
Score: 79%
Lower.
But stable.
Rei's gaze sharpened slightly.
Interference efficiency decreasing.
The girl stepped down.
"…You don't break easily," she said.
Airi looked at her briefly.
"…No."
Simple.
The answer held weight.
Phase three began.
Reaction timing.
Lights flashed.
Signals changed rapidly.
Each pair had to respond in perfect sync.
Any delay—
Penalty.
Airi focused.
The first signal came.
Left.
They moved.
Aligned.
Second.
Right.
Aligned.
Third.
Split.
The girl delayed—
Just enough.
Airi felt it.
The timing broke.
Penalty.
Her chest tightened slightly.
No.
She corrected.
Not matching the delay—
Anticipating it.
The next signal came.
She moved before the disruption.
Aligned again.
The system adjusted.
Score: 76%
Lower.
But stable.
The pattern was clear.
The interference was working—
Partially.
But not enough.
Rei stepped slightly forward.
Still outside the system.
Still observing.
But closer.
Airi noticed.
Only for a moment.
Then she refocused.
The connection remained.
Even without direct interaction.
The final phase began.
Full synchronization.
Movement.
Timing.
Decision-making.
Combined.
Maximum pressure.
Airi stepped forward.
The girl matched her.
For the first time—
Without disruption.
Airi noticed.
A slight shift.
"…Why?" she asked quietly.
The girl didn't look at her.
"Because now I want to see."
A pause.
"…How far you can go."
The tone had changed.
From interference—
To evaluation.
The signal came.
They moved.
Perfect alignment.
No delay.
No disruption.
For the first time—
True synchronization.
The system registered it.
Score: 91%
The highest so far.
Silence spread across the field.
Students watched.
Not with doubt.
But recognition.
Airi stepped back.
Her breathing was controlled.
Her posture steady.
Rei approached.
No rush.
No urgency.
Only certainty.
"…You adapted," Rei said.
Airi nodded.
"…And?"
Rei's gaze held hers.
"You improved."
Simple.
But absolute.
Airi exhaled slowly.
"…Good."
Rei turned slightly.
The system had changed again.
Scores updated.
Class rankings shifted.
The gap was narrowing.
Other classes had begun adapting.
The pressure would increase.
Rei knew it.
"They won't stop here," she said.
"…Neither will we," Airi replied.
Rei looked at her.
A pause.
Then—
A single nod.
"Prepare," she said.
The next phase would not test synchronization.
It would test control.
And this time—
Rei would not remain outside.
