The system interface hovered in the air like an overconfident hologram.
Blue light reflected across Horikita's glasses as streams of incomprehensible data scrolled endlessly.
ADMIN AUTHORITY CONFIRMED
HORIKITA SUZUNE. DESIGNATION - MULTIVERSE CLASSROOM DIRECTOR
Horikita stared at it.
"…This must be a mistake."
The system immediately responded.
ERROR: ADMIN DOES NOT DENY RESPONSIBILITY
Gojo leaned over her shoulder. "Yeah, that's how god-tier software works. Once you click 'Accept Terms and Conditions,' your life is over."
"I didn't click anything."
CONSENT DETECTED THROUGH LEADERSHIP COMPETENCY
Horikita pinched the bridge of her nose.
Ayanokoji stood a few steps behind her, arms crossed, eyes scanning the interface with cold focus. His mind was already racing, trying to reverse-engineer the system's logic.
"…So you're telling me," he said slowly, "Horikita is now the administrator of a multiverse classroom."
"Yes," the system replied cheerfully.
Gojo whistled. "That's wild. She went from student council potential to reality manager in one afternoon."
Itachi folded his arms. "This exceeds my job description."
Horikita straightened her posture.
If this was real and all signs suggested it was then panicking was pointless.
"…System," she said calmly. "What exactly is the Infinite Semester?"
The interface shifted.
INFINITE SEMESTER PROGRAM
PURPOSE: TO IDENTIFY THE OPTIMAL EDUCATIONAL STRUCTURE ACROSS REALITIESMETHOD: COMPETETIVE INTEGRATION OF ELITE INDIVIDUALS FROM MULTIPLE UNIVERSESSUCCESS CONDITION: FORMATION OF THE STRONGEST FUNCTIONAL CLASSROOM UNIT
"…In simple terms?" Horikita asked.
YOU RUN SCHOOL. MULTIVERSE EDITION
Silence dawned upon everyone.
Ayanokoji exhaled slowly.
"So this is the variable I didn't predict."
Horikita turned toward him.
"And what are you planning to do now?"
He met her gaze.
"Win."
The stone hall trembled.
A loud notification echoed through the space.
PHASE ONE INITIATED: STUDENT ENROLLMENT
Reality tore open.
Dozens of portals appeared in midair, arranged in a massive circular formation.
Horikita instinctively took a step back.
"Wait—what does enrollment mean exactly?"
The answer arrived immediately.
The first portal opened wide.
A teenager in a brown jacket stumbled forward, eyes blazing with intensity.
"Where am I?" he demanded. "Is this another battlefield?"
Horikita glanced at the system.
"Name?"
EREN YEAGER - COMBAT TYPE STUDENT - HIGH AGRESSION
"Combat-type?" Horikita repeated. "But this is a school."
Eren clenched his fists. "If this is another place trapping me, I'll—"
"Homeroom is on the second floor," Horikita said flatly. "Seat near the window. Don't break anything."
Eren froze.
"…What?"
Before he could argue, another portal opened.
A tall student with sharp eyes and a regal posture stepped forward, cape somehow flowing despite zero wind.
"I am Lelouch vi Britannia," he declared dramatically. "And I will not be commanded by—"
"You're class representative for presentation tasks," Horikita interrupted. "Your speaking skills are optimal."
Lelouch blinked.
"…Excuse me?"
Another portal.
A young man with messy brown hair appeared, immediately looking stressed.
"Why do I feel like something terrible is about to happen?"
SUBARU NATUSUKI - MENTAL ENDURANCE: EXTREME
Horikita nodded.
"Group coordination unit."
Another portal opened.
A handsome student with a notebook in hand stepped out calmly.
Light Yagami scanned the room.
"…Interesting. This environment suggests a hierarchical structure—"
"You're on attendance duty," Horikita said instantly.
"What."
"Daily roll call. No exceptions."
Portals continued opening.
More students poured in. Strategists, fighters, geniuses, overpowered anomalies who clearly did not belong in a normal school environment.
Within minutes, the stone hall was crowded.
Arguments broke out.
Someone challenged someone else to a duel. Another demanded leadership and thus chaos began forming.
Horikita stepped forward.
She raised her hand slightly.
"I will explain this once."
Her voice wasn't loud.
But it cut through the noise.
"Welcome to the Infinite Semester. You are now students. You will attend classes. You will follow rules. You will complete assignments. If you don't…"
She glanced at the system.
"…your academic performance will be evaluated permanently across realities."
The system helpfully added:
FAILURE PENALTY: CAREER TRAJECTORY DISTORTION
Everyone froze.
"…That sounds bad," Subaru whispered.
Horikita nodded. "It is."
Behind the crowd, Ayanokoji quietly stepped away.
While Horikita was organizing chaos, he was already planning countermeasures.
He slipped into a shadowed corridor.
His phone buzzed.
A familiar voice spoke.
"…You finally called."
Batman.
"I need resources," Ayanokoji said calmly. "Strategy, counter-intelligence, psychological warfare."
Batman replied instantly.
"I already ran simulations. Horikita's leadership pattern suggests efficiency-based dominance. Emotional manipulation won't work."
"…Then what will?"
"Disruption of system reliance. You can't beat her directly."
Ayanokoji's eyes sharpened.
"You change the game."
Another voice joined the call.
"I brought cake."
L.
"Why are you here?" Ayanokoji asked.
"Because this situation is statistically fascinating," L replied calmly. "Also, I dislike losing."
Ayanokoji replied,
"Then it's decided."
He looked back toward the massive classroom forming in the distance, where Horikita was already issuing schedules and organizing seating arrangements.
"…The Desperate MC Alliance begins now."
Back inside the main hall, Horikita stood before the growing student body.
The system projected a massive screen behind her.
SPECIAL EXAM ANNOUNCEMENT
TITLE: CLASSROOM FOUNDATION TESTOBJECTIVE: ESTABLISH STABLE ORGANIZATIONAL STRUCTURE WITHIN 24 HOURSFAILURE RESULT: CLASS RESET
Murmurs spread instantly.
Horikita adjusted her glasses.
"This is our first test."
Eren raised his hand aggressively.
"Do we fight?"
"No."
Lelouch smirked. "Do we manipulate?"
"Only if it improves efficiency."
Subaru looked terrified. "Is there any normal option?"
Horikita smiled faintly.
"No."
From across the hall, Ayanokoji watched silently.
Two leaders.
One system.
One semester.
And a multiverse that had just turned academic competition into a battlefield.
The war for the ultimate classroom had officially begun.
