The lecture hall remained unsettled after Noctis sat back down. Students continued pretending to return to their notes, but the atmosphere inside the room no longer carried the same ordinary lecture rhythm that existed earlier. Pens still moved across parchment and the layered lightning formation continued rotating slowly behind Instructor Seraphine near the lower platform, yet attention throughout the hall remained divided between the unfinished lesson and the student resting in the upper rows with his eyes closed after dismantling the combat practicality of the lecture itself. Chalk dust drifted gradually beneath the mana lights embedded into the walls, and every so often the sound of pages turning or desks shifting echoed faintly through the tiered seating while students adjusted posture trying to decide whether the discussion had actually ended.
Instructor Seraphine stood beside the formation board with one hand resting lightly against the lecture desk. The expression she maintained remained controlled, though irritation had begun showing around her eyes despite her efforts to suppress it professionally. Her original intention at the end of the review had been simple enough. She expected Noctis to embarrass himself after appearing asleep throughout the lecture. Instead, he explained the structure correctly, identified practical flaws inside the activation sequence, and spoke about battlefield application with the tone of someone evaluating a real combat tool rather than reciting theory from a textbook.
That irritated her more than the criticism itself.
Several students near the center rows quietly resumed copying notes from the floating diagram while still listening to the exchange at the front of the room. A dragonkin student adjusted the mana flow inside a practice circle she had accidentally destabilized earlier, and somewhere toward the lower rows another student whispered something about Noctis actually making sense before his friend elbowed him to stop talking.
Instructor Seraphine folded one arm beneath the other while looking toward the upper seating rows.
"You speak very confidently," she said, her tone measured enough that the sarcasm remained controlled rather than openly hostile, "for someone who has never formally studied advanced magical theory."
Noctis remained leaned back against the bench while the students around him became visibly more attentive again.
"Theoretical combat structure exists for more than direct confrontation," Instructor Seraphine continued while gesturing toward the rotating lightning formation behind her. "Properly prepared magic circles can reshape battlefield positioning, suppress enemy movement, reinforce defensive sectors, or eliminate targets stronger than the caster themselves."
Noctis opened one eye slightly.
"I already said they're useful for traps."
"That is an oversimplification."
"It's still correct."
The answer came casually enough that several nearby students immediately looked between the two more carefully. The lecture hall remained physically active around the conversation. One student near the front continued writing while glancing upward every few seconds. Another quietly closed a notebook after realizing no one around him was actually paying attention to the lesson anymore.
Instructor Seraphine's fingers tightened slightly against the edge of the desk.
"The Academy has refined combat formations for generations. Battlefield applications require understanding beyond simply rushing an opponent directly."
Noctis looked toward the lightning diagram again while the outer rings rotated steadily above the lower platform.
"And how many of those generations died before finishing the circle?"
The room became quieter afterward, though not silent. Someone farther back shifted a chair. A pen rolled briefly across one desk before being caught. The movement of mana inside the lecture formations continued humming softly beneath the ceiling arrays while the students absorbed the question.
Instructor Seraphine recognized immediately that Noctis was no longer discussing theory academically. He was evaluating the lecture from practical combat experience. Worse, portions of his reasoning aligned with battlefield casualty reports involving inexperienced circle users who relied too heavily on setup casting during close-range engagements.
Still, being challenged publicly by a student in the middle of her own lecture irritated her enough that professionalism began competing against pride.
"You criticize combat application very casually," she said while maintaining eye contact toward the upper row. "I assume you believe your own understanding superior."
Noctis immediately noticed the change in tone beneath the professionalism.
The students noticed it too.
Several of them had already heard rumors about Noctis forcing even upper Academy authorities into intervention only days after arriving. Most had never actually seen him fight personally, but enough stories circulated already that the atmosphere inside the lecture hall gradually became more tense as the exchange continued.
Noctis lowered his feet from the desk and sat upright while adjusting the edge of his coat behind him.
"If the circle works well in combat," he said calmly, "then demonstrate it."
Instructor Seraphine narrowed her eyes slightly.
Noctis continued before she answered.
"Use the circle against me."
The students throughout the lecture hall reacted immediately, though not dramatically. Some shifted farther back instinctively. Others exchanged uncertain looks while trying to determine whether the conversation had just become an actual challenge. One student quietly gathered loose papers from his desk as though preparing for the possibility that mana might start flying across the room.
Instructor Seraphine herself looked briefly surprised.
"This is a classroom."
"You spent the entire lecture discussing battlefield practicality." Noctis rested one arm against the back of the bench while looking down toward her. "Seems like a reasonable place to test battlefield practicality."
The instructor hesitated.
That hesitation alone told Noctis enough.
"What happened?" he asked afterward. "You sounded pretty confident earlier."
A few students visibly tensed harder.
Noctis tilted his head slightly while continuing to watch her.
"Or maybe you already know it won't work."
That finally pushed the situation past simple academic disagreement.
Instructor Seraphine inhaled slowly before setting the chalk fully onto the desk beside the formation board. Mana pressure gradually gathered around her raised hand while students near the lower platform shifted backward to create more space. The lecture hall itself remained active around the tension. Several floating instructional diagrams still rotated behind her. Students farther toward the back whispered quietly while trying not to appear too obvious about it. A notebook slipped from someone's desk near the side rows and hit the floor before quickly being retrieved.
"Fine," Instructor Seraphine said.
Lightning-aspected mana gathered around her fingertips while the pressure necessary to begin constructing the outer framework of the circle stabilized gradually around her hand.
Noctis watched her calmly.
From his perspective, the problem already existed before the first rune formed.
Her posture shifted slightly while preparing the activation sequence. Mana circulation gathered toward the dominant hand first before redistributing into the initial pathway structure. The opening movement alone already created enough delay that a real opponent standing this close would never allow completion.
Instructor Seraphine raised her hand slightly higher while focusing on the first formation layer.
Before the initial rune structure even began taking shape, the pressure beside her changed.
Noctis crossed the classroom without disrupting the lecture formations overhead or producing any explosive acceleration across the floor. The students nearest his previous seat physically noticed the absence of his presence before understanding the movement itself, and the bench where he had been resting still carried slight motion from where his weight shifted away moments earlier.
Instructor Seraphine instinctively felt something touch beneath her chin before her mind fully processed what happened.
The contact itself was light.
Controlled.
Not forceful.
Her eyes lowered slightly afterward, and the black barrel of Nocturne rested beneath her jawline angled upward just enough that the instructor's breathing immediately became uneven. The mana she had been gathering around her hand destabilized before the first rune finished forming.
Only then did she notice Noctis standing beside her.
One hand remained inside his coat pocket.
The other held Nocturne beneath her chin calmly while he looked toward the unfinished mana pressure gathering near her raised hand.
"You would already be dead," Noctis said quietly enough that the students nearest the lower platform had to listen carefully to hear him. "Several times over."
Instructor Seraphine felt cold sweat begin forming almost immediately afterward.
Not because the weapon frightened her directly.
Because she never saw him move.
The students throughout the lecture hall remained completely focused now. Several looked toward the empty upper-row seat before turning back toward the lower platform trying to understand how Noctis crossed the entire room before the first rune even appeared. Others stared directly at the unfinished mana pressure still flickering weakly around the instructor's fingers.
Noctis lowered Nocturne slightly afterward while continuing to speak in the same calm tone.
"That's the problem with direct combat circle casting. Setup time kills the user first."
The unstable lightning mana around Instructor Seraphine's hand dispersed fully once her concentration broke.
Noctis pulled Nocturne away afterward and rotated it once casually before returning it smoothly into the holster beneath his coat.
The classroom bell rang at nearly the same moment.
The sound spread through the lecture hall while students remained seated longer than normal processing the demonstration that just happened. Outside the classroom, footsteps and voices from other lecture halls already filled the corridor as students transitioned toward their next classes throughout the Academy.
Reality continued moving despite the confrontation.
Noctis stepped away from Instructor Seraphine while adjusting the lower edge of his coat.
"Thanks for the lesson."
Then he walked toward the exit.
Instructor Seraphine remained standing near the lecture platform afterward while students gradually began collecting books, notes, and formation plates around her. Several still glanced toward her uncertainly while discussing the movement skill under their breath. Others kept looking toward the doorway Noctis had already passed through.
The instructor herself had still not fully processed the distance he crossed before she could begin the first rune.
Outside the lecture hall, the Academy corridors carried the usual chaos of class transition periods. Hundreds of students moved between instructional sectors beneath the tall archways overhead while floating direction markers shifted along the walls indicating upcoming lecture schedules. Voices overlapped continuously throughout the corridor. Some students discussed assignments. Others argued about combat rankings, mission rewards, or faction politics while making their way through the crowded halls.
Noctis had barely walked halfway down the corridor before students from the lecture hall began catching up to him.
At first only several.
Then more joined naturally while the crowd moved through the hallway together.
"How did you move that fast?"
"Was that a movement technique?"
"You crossed the room before she even started the circle."
Noctis answered while continuing toward the martial training districts.
"Movement skill."
"Mostly acceleration and positioning."
"The circle itself was too slow."
Students walking beside him listened carefully while continuing through the corridor traffic. Several female students gradually moved closer into the conversation while others nearby pretended not to listen and failed completely.
One fox demon girl carrying lecture books against her chest looked toward him curiously.
"Where did you learn practical combat?"
"Fighting things trying to kill me."
"That sounds horrible."
"It usually is."
The answer made several students laugh quietly.
Another student farther back asked whether the rumors about Bahamut were true. Noctis answered honestly enough that the group gradually relaxed around him. The social atmosphere became less tense the longer the conversation continued because Noctis himself did not behave arrogantly despite everything surrounding his reputation. He answered questions directly, spoke casually, and never acted like ordinary conversation annoyed him.
Eventually the discussion shifted naturally away from combat topics.
"Do you have a girlfriend?"
"No."
"What kind of girls do you like?"
"Haven't really thought about it."
"What do you usually do outside training?"
"Fight. Train. Sleep."
Several students laughed again while continuing alongside him through the Academy roads.
Nobody asked about food.
Everyone present already knew he was a vampire, and enough social awareness still existed not to bring up blood consumption casually in the middle of a hallway conversation.
One male student carrying training gear eventually looked toward Noctis.
"What's your next class?"
"Combat training."
A few students immediately responded that they shared the same class, and before long the entire group naturally shifted together toward the combat sectors bordering the military district. The farther they traveled from the educational halls, the harsher the atmosphere became. Weapon impacts echoed from nearby arenas. Mana explosions flashed intermittently from spell training zones. Dust drifted across portions of the open fields where students sparred beneath combat instructors shouting corrections loud enough to carry across multiple sectors.
The training field assigned to their next class occupied one of the larger reinforced arenas near the eastern combat district. Stone barriers surrounded the field itself while portions of the ground carried visible damage from previous exercises: cracked sections of reinforced flooring, scorch marks from spell impacts, and shallow craters left behind by heavier combat techniques.
A massive red-skinned Vajra demon stood near the center training area shouting instructions toward another group already lined up across the field.
The moment he noticed the approaching students, his voice thundered across the arena again.
"LINE UP!"
The students beside Noctis immediately moved into formation.
Noctis kept walking normally toward the line.
The Vajra instructor's eyes locked onto him immediately.
"You too!" the instructor barked. "Move faster!"
Noctis stopped briefly and looked toward him.
The stare itself remained calm.
Cold.
Predatory enough that several nearby students instinctively shifted uncomfortably.
The Vajra instructor felt it too, though his expression only hardened further.
Before the atmosphere could escalate, however, the students already standing in formation shifted sideways creating enough space in the line for Noctis to enter immediately.
"Noctis," one whispered urgently. "Here."
"There's space."
Noctis looked toward the opening and simply stepped into position between a fox demon girl and a pale ice witch while the rest of the line quietly relaxed.
The Vajra instructor continued pacing across the field afterward while beginning the lecture on battlefield mobility against Holy Church formations. His teaching style differed heavily from Instructor Seraphine's. Less theory. More direct military practicality.
"Standing still gets you killed," the Vajra barked while pacing in front of the formation line. "Church casters will erase stationary targets first. Movement controls survival."
The students remained attentive while dust moved steadily across portions of the field from nearby combat exercises happening in surrounding arenas.
The instructor eventually demonstrated a movement acceleration technique despite his massive size. Mana pressure gathered around his legs before releasing explosively across the field, allowing the enormous Vajra to cover distance far faster than most students expected possible from something built like a fortress.
Several students reacted with genuine admiration.
Noctis did not.
From his perspective, the movement remained painfully inefficient. The startup delay, weight transfer, and acceleration buildup created openings large enough that he mentally calculated dozens of kill opportunities before the instructor completed the run.
He yawned lightly.
The Vajra immediately noticed.
"You," the instructor growled while turning toward the line again. "Step forward."
Noctis walked out calmly while students nearby became visibly uncomfortable.
"You think this is amusing?"
"No."
"Then why are you yawning?"
"The movement skill is too slow."
The instructor's expression darkened immediately.
"Ten laps around the field."
Noctis looked toward the enormous training ground briefly before answering.
"That's a waste of energy."
The students beside the formation line physically stiffened.
Noctis continued calmly before the instructor exploded fully.
"If you want to demonstrate the movement skill properly, then attack me with it instead."
The field atmosphere tightened naturally afterward. Nearby combat sounds from surrounding arenas still continued in the background while wind carried dust across the cracked training stone beneath their feet.
The Vajra instructor roared and activated the movement technique immediately.
Mana burst through the lower portions of his body while the massive demon accelerated directly toward Noctis across the field.
Crimson formation pressure spread beneath the ground first.
Then chains emerged upward through the training stone in overlapping angles around the instructor's path. The chains wrapped around his limbs, torso, and shoulders while anchoring themselves back into the cracked field beneath him, and the force of his own forward momentum tightened the restraints harder the moment the charge stopped abruptly.
Stone fractured beneath the sudden pressure shift.
The Vajra strained violently against the restraints while crimson runes pulsed faintly across the chain surfaces.
Noctis walked toward him calmly afterward while the students watched the scene in stunned silence.
Then he turned toward the formation line.
"These are crimson chains," he explained while the restrained Vajra continued struggling behind him. "Much more useful in practical combat than random sprinting."
Several students failed to suppress laughter entirely after hearing that while their instructor remained trapped inside the chains only several steps away.
Noctis gestured lightly toward the restrained demon.
"Frontal charges are predictable. Especially from large opponents."
The students continued staring between Noctis and the chains while realization gradually spread across the formation line.
They had just left a lecture discussing advanced combat formations theoretically.
Now Noctis casually demonstrated battlefield restraint magic strong enough to immobilize a charging Vajra instructor mid-attack without visible setup time at all.
Even more importantly, multiple chains activated simultaneously from different positions beneath the ground, meaning Noctis had layered the restraints with enough precision to account for movement trajectory before the charge even completed.
Dust drifted slowly across the training field while nearby combat classes continued operating around them, and Noctis continued explaining battlefield control as though trapping the combat instructor in front of the entire class was simply another ordinary lesson.
