Morning light spilled across the classroom windows, pale and cold, as if the sky itself had chosen caution over warmth.
The students of Class D arrived in uneven waves.
Some spoke quietly.
Some avoided eye contact.
Others pretended nothing had changed.
But the atmosphere had shifted.
The confrontation between Rei and Yamauchi still lingered in the room like a faint echo no one had managed to silence.
Rei sat at her desk near the window.
Her notebook was already open.
A thin pen moved across the page with quiet precision.
Observation lines. Behavioral notes. Social reactions.
Across the room, Yamauchi was studying.
Not pretending.
Actually studying.
The tension from the challenge had forced him into preparation.
Pressure had predictable effects.
Some people collapsed under it.
Others worked harder.
Rei wrote a short line.
Stress response: academic compensation.
Her pen paused.
Then continued.
Several other students had changed behavior too.
Three had begun sitting closer to Yamauchi.
Two others had distanced themselves.
Temporary alliances forming.
Exactly as expected.
The classroom door opened.
Their teacher stepped inside.
The room gradually settled into silence.
But something about the teacher's expression immediately changed the atmosphere.
Calm.
Too calm.
Students noticed.
Whispers faded.
Chairs stopped moving.
The teacher placed a folder on the desk.
Then she spoke.
"Today I have an important announcement."
A pause followed.
"Your first Special Test will begin this week."
The reaction was immediate.
Several students sat upright.
Others exchanged nervous looks.
Special Tests were not ordinary exams.
At Advanced Nurturing High School, they often decided the fate of entire classes.
Points.
Reputation.
Rank.
Everything could shift overnight.
The teacher opened the folder.
"This examination is called the Strategic Consensus Test."
Horikita raised her hand immediately.
"What is the objective of the exam?"
"Each class will be divided into mixed groups with students from other classes."
The room went still.
Mixed groups?
The teacher continued.
"Each group will contain three students. One from three different classes."
Murmurs spread through the classroom.
Rei continued writing.
Inter-class interaction.
Information exchange.
Psychological pressure.
Interesting structure.
The teacher wrote several numbers on the board.
"Inside each group, one student will secretly be designated as the VIP."
More murmurs.
"If the other students correctly identify the VIP, their class receives a large number of points."
"And if they guess wrong?" someone asked.
The teacher turned slightly.
"Then the accusing class will lose a significant amount of points."
The room grew quieter.
Now the stakes were clear.
Wrong accusations would be punished heavily.
The teacher added one more sentence.
"Communication between groups is permitted."
That detail changed everything.
Rei's pen stopped.
Information sharing between groups.
Which meant deception would become a viable strategy.
Horikita's eyes narrowed.
"So negotiation between classes is allowed?"
"Yes."
"Without restriction?"
"Correct."
Horikita leaned back slightly.
The exam was not about knowledge.
It was about trust.
Or more precisely—
The destruction of trust.
Across the room, Yamauchi looked overwhelmed.
"This sounds impossible," he muttered.
A few students nodded nervously.
"How are we supposed to figure out who the VIP is?"
"We'll just guess," someone suggested weakly.
"That's suicide."
The teacher closed the folder.
"The examination will last three days."
Another wave of tension spread across the room.
Three days of constant suspicion.
Three days of interaction with rival classes.
Three days where a single mistake could destroy their position.
Then the teacher revealed the final piece.
"Your groups will be announced tomorrow morning."
The bell rang.
Class ended.
But no one moved immediately.
The weight of the announcement had frozen the room.
Finally, conversations erupted all at once.
Students began discussing theories.
Strategies.
Fears.
Rei closed her notebook.
She had already understood the structure.
This exam was not designed to measure intelligence.
It was designed to measure how easily intelligence could be manipulated.
Horikita approached Rei's desk.
"You were writing again," she said.
"Yes."
"What did you conclude?"
Rei looked up.
"The exam rewards misinformation."
Horikita crossed her arms.
"Explain."
"If information moves between classes, then false information becomes a weapon."
Horikita considered that.
"Yes. But spreading lies is dangerous. It could backfire."
"Correct."
"Then why would anyone attempt it?"
Rei answered calmly.
"Because the risk can be calculated."
Horikita studied her expression.
"You sound like you've already formed a strategy."
"I have formed several possibilities."
Horikita hesitated.
Then asked the real question.
"Will you share them with the class?"
Rei closed the notebook.
"That depends."
"On what?"
"On whether the class will follow instructions."
Horikita's eyes narrowed.
"You expect obedience?"
"No."
Rei stood up slowly.
"I expect predictability."
That answer irritated Horikita slightly.
But she didn't press further.
For now.
During lunch, the tension only increased.
Every class in the cafeteria was discussing the same topic.
The Special Test.
Groups.
VIP identification.
Across the room, several students from other classes were also observing Class D.
Their recent internal conflict had already attracted attention.
Rei sat quietly with her tray.
Kei arrived moments later and dropped into the seat across from her.
"Well," Kei said, leaning forward slightly, "this got interesting fast."
Rei nodded once.
"You don't look worried," Kei observed.
"Concern would not improve the outcome."
Kei smiled faintly.
"You're impossible."
She leaned closer.
"So tell me. What's your first impression?"
Rei took a small sip of water.
"The exam is simple."
Kei blinked.
"Simple?"
"Yes."
"Everyone else looks terrified."
"Because they are focusing on the wrong problem."
Kei tilted her head.
"And the right problem is?"
Rei answered without hesitation.
"People."
Kei studied her face carefully.
"You mean the other students."
"Yes."
"The exam isn't about finding the VIP," Rei continued.
"It is about controlling who believes what."
Kei leaned back slowly.
"That's… actually terrifying."
Rei said nothing.
Across the cafeteria, another pair of eyes had also been watching her.
From a table near the window, a girl with long silver hair observed the interaction quietly.
Her expression was calm.
Almost amused.
Arisu Sakayanagi had already noticed the unusual atmosphere surrounding Class D.
More specifically—
She had noticed the quiet girl near the center of it.
The one who did not appear anxious.
Or excited.
Or curious.
Simply attentive.
Sakayanagi rested her chin lightly on her hand.
Interesting.
Very interesting.
She had watched many students react to Special Tests before.
Most showed nerves.
Some showed ambition.
A few showed fear.
But that girl from Class D had shown none of those reactions.
Only calculation.
Sakayanagi smiled slightly.
This exam might be more entertaining than she had expected.
Later that afternoon, as the final bell rang, students left the building in uneasy clusters.
Strategies were forming.
Alliances were being discussed.
Rei walked alone.
Kei eventually caught up beside her.
"So," Kei said casually, "groups get announced tomorrow."
"Yes."
"You're hoping for strong teammates?"
"No."
Kei laughed.
"Of course you aren't."
Rei looked ahead calmly.
"The composition of the group does not matter."
"Oh?"
"What matters is how they react under uncertainty."
Kei glanced at her.
"You really see everything as an experiment."
"Yes."
Kei walked silently for a few seconds.
Then she asked something quietly.
"And what happens if someone tries to manipulate you?"
Rei considered the question.
Then answered simply.
"They are welcome to try."
Kei smiled.
Something about that answer was strangely reassuring.
And strangely dangerous.
The following morning would reveal the group assignments.
And once the groups formed—
The real game would begin.
