Transmigrating as an Extra, But the Heroine Has Regressed?!-Chapter 313: Nathan’s Magic!

The wooden straw dummy was gone.

Nathan blinked several times, unable to process the scene.

"That... that... wasn’t a dummy anymore," one first-year whispered in fear.

"He turned it into powder," another added.

Nathan swallowed hard.

He didn’t even remember blinking.

He didn’t remember seeing the blade arc.

One moment Kael lifted the sword.

The next—the dummy vanished.

"What... the..." Nathan whispered again, as if hoping the dust cloud would give him an answer.

Kael looked at the sword like a confused child lifting a toy for the first time.

"...Was that weird?" Kael asked.

Nathan snapped his head toward him.

"Did he just ask if that was weird?" he shouted at the first-years.

All of the first-years nodded stiffly.

Kael blinked again.

"I just used the same strength I always do..."

Nathan almost fell to his knees.

"The same strength!?" he squeaked.

"You nearly turned that dummy into ash!"

Kael scratched his cheek awkwardly.

"Sorry..."

The room stayed silent for a few seconds.

Then the silence turned into sweat.

Literal sweat.

Everyone felt it.

Nathan wiped the moisture on his forehead.

(This kid... he’s not a normal person. He’s a walking calamity. And Sylvia just casually told me to deliver this... heavy, cursed sword to him?)

He stared at the sword.

Then at Kael.

Then at the sword again.

The sword was heavier than a boulder earlier.

So heavy Nathan could barely lift it with both hands.

And Kael—

Kael held it with ONE hand like it weighed no more than a chopstick.

The first-years exchanged terrified glances.

"That sword must weigh 27 kilos..."

"And he swings it like it’s nothing..."

"He’s a monster..."

Kael didn’t notice their fear.

He lifted the sword again, casually resting it on his shoulder.

"Senior Nathan," Kael said politely, "do you want to see me swing faster?"

Every first-year flinched.

"NOOO!!" Nathan shouted, waving his hands frantically.

"Don’t! Don’t swing anything! Don’t move anything! Don’t breathe aggressively!"

Kael lowered the sword slowly.

"...Okay."

Nathan exhaled heavily.

Nathan Tries to Understand Kael

Nathan rubbed his temples.

"Kael... how long have you been training?"

Kael shrugged.

"Just a little. Not much."

Nathan nearly coughed blood.

(That power is ’not much’???)

He inhaled deeply.

"Kael... you’re strong. Very strong. But strength alone won’t work in this academy. You need control. You need technique. And most of all—magic."

Kael tilted his head.

"...Magic?" 𝗳𝚛𝗲𝕖𝚠𝚎𝚋𝗻𝗼𝕧𝗲𝐥.𝚌𝚘𝐦

"Yes," Nathan said. "Do you know how to use it?"

"No," Kael replied honestly.

Nathan nodded slowly.

"Okay... okay. Then I’ll show you something simple. A basic mana flow."

The first-years’ eyes widened.

Nathan was ranked #1 in third year.

His magic was no joke.

Nathan raised his hand, channeling mana from his core to the blade.

A faint blue aura shimmered along the metal, humming with controlled power.

The glow was soft.

Graceful.

Elegant.

"This," Nathan explained, "is basic mana reinforcement. The simplest form of sword magic. Anyone in second year can do this. Even some first-years."

The aura surrounding his sword pulsed gently.

Kael watched silently.

His eyes focused.

Nathan lowered his hand.

"See? That’s how it looks."

Kael nodded.

"...Can you do it again?" he asked softly.

"Sure..."

Nathan activated it again.

Kael’s expression did not change.

He didn’t blink.

He absorbed every inch of the movement.

Every flow.

Every pulse.

Nathan deactivated the magic.

"That’s all. It takes months for most first-years to even feel mana. Don’t wor—"

Nathan stopped.

Kael raised his sword.

Nathan’s heart jumped.

"No, no, no, no, wai—"

FWOOM—!!

Kael’s sword ignited.

But a violent, swirling wave of dark-silver energy surged around the blade, crackling like a storm.

The pressure hit Nathan like a wall.

"W–W–What!?" Nathan fell backward.

The first-years clung to each other in sheer terror.

Kael looked... confused again.

"...Did I do it right?"

"RIGHT?" Nathan choked. "RIGHT?! You copied my mana flow in ONE LOOK!"

Kael lowered the blade, the dark-silver aura dissipating.

"I watched carefully," Kael said simply. "Just like you showed me."

Nathan stared blankly.

(This... he’s copying third-year mana technique like he’s copying breathing.)

The first-years were pale white.

"That was not normal..."

"He activated mana on his first try..."

"He copied a third-year perfectly..."

"He’s scary..."

Kael sighed, embarrassed again.

"I didn’t mean to scare anyone..."

Nathan stood up, legs shaking.

"Kael... never... EVER tell another professor you learned mana that fast. They’ll lock you in a lab."

Kael blinked.

"Huh? Why?"

Nathan grabbed his shoulders.

"Because it’s impossible! That’s why!"

Kael rubbed the back of his neck, unsure how to react.

Nathan steadied himself, inhaling deeply.

"...Kael."

"Yes?"

"Can you use magic?"

"No. I don’t know how."

Nathan nodded slowly.

"Good."

Then he leaned in and poked Kael’s forehead.

"Stay. That. Way."

Kael tilted his head again.

"But I want to learn."

"No," Nathan said, shaking his head like a frightened dog.

"Absolutely not. Never. I refuse. I will NOT teach you."

"But—"

"No."

Kael stared at the floor like a rejected child.

"...Okay then."

Nathan sighed in relief.

Kael Leaves the Room.

Kael walked toward the door, carrying the heavy sword over his shoulder.

The first-years stepped away from him like he was a plague beast.

"D-Don’t look at him."

"What if he explodes another thing?"

"Don’t breathe near him...."

Kael felt awkward and slightly sad.

"Why were they so scared of him?"

"He didn’t even hit them.

He just hit...

that dummy...

...into dust."

Kael stepped out of the training room.

Nathan Collapses to the Floor

As soon as Kael stepped outside, Nathan dropped to the ground.

"Haaah... haaah..."

He wiped the sweat dripping from his chin.

"Did I... survive that?"

One first-year whispered:

"Senior Nathan... are you okay?"

Nathan grabbed the wall dramatically.

"I’m not okay. My pride is broken. My body is broken. My soul is broken."

The first-year gulped.

"What... what do we tell others?"

Nathan glared.

"You tell them NOTHING. If anyone finds out a first-year copied my magic in one try, people will start saying I’m a weak teacher!"

He stood up shakily.

"And I am NOT weak!"

The first-years nodded quickly.

"N-no, senior! You’re strong!"

"Very strong!"

Nathan puffed his chest.

"Of course I am."

But inside his thoughts were different.

(Kael... that boy... he’s not a normal first-year. He’s another beast like the top prodigies of the academy.)

Kael carried his sword carefully, making sure not to hit anything.

Students in the hallway glanced at him and took one step back... then two steps back...

Some even ran away in fear.

Kael sighed.

"Why is everyone looking at me like that...?"

He reached the courtyard.

It was empty.

Kael inhaled deeply.

"I should go back to my dorm..."

He started walking—

Then suddenly stopped.

"Magic..."

He thought about the flow he saw from Nathan’s hand.

The glow.

The aura.

The swirling energy.

He raised his sword slightly.

"I want to try it again."

Kael closed his eyes, remembering every detail Nathan did.

He imagined mana flowing from the center of his body... through his arm... into his palm... and finally into the sword.

His breathing slowed.

His mind cleared.

And then—

FWOOM—!!

The dark-silver aura erupted again, swirling wildly around the blade, faster than before.

Kael let out a small gasp.

"...I really did it."

The aura danced around the blade.

He tightened his grip.

"Edwin will be shocked when he hears this..."

He smiled slightly.

"But I should rest. I still need to avoid Elysia today..."

He sheathed his sword and began walking toward his dorm.

That someone was watching him from the rooftop above.

A pair of cold, analyzing eyes.

Elysia.

She whispered to herself:

"He’s growing too fast..."

Meanwhile, in the infirmary.

Edwin slowly opened his eyes.

He groaned, rubbing his forehead.

A maid beside the bed gasped.

"Young Edwin? You’re awake!"

Edwin blinked a few times. "Huh...? Where am I? How long was I out?"

"You’re in the academy infirmary," the maid replied while adjusting the blankets. "You’ve been asleep for two days."

"Two... days?" Edwin pushed himself up. His ribs ached, and his shoulder still felt bruised. "That long?"

"Yes. Madam Sylvia personally checked on you. She said your injuries were severe but stable."

Edwin clenched his fist under the blankets.

Two days... Elysia really pushed me this time.

The maid hesitated, then asked, "Do you need anything?"

"Water... and information." Edwin sighed. "What happened after the fight?"

"I heard that most students returned to training. They said the courtyard was noisy for days, especially because of Kael Ashford."

Edwin’s eyes narrowed. "Kael...?"

The maid nodded. "People say he’s been training nonstop. Morning and night."

Edwin leaned back, staring at the ceiling.

"...He’s improving faster than I expected. That low level weak man"

Meanwhile, in Kael’s dorm...

The night was quiet. Only the sound of Kael’s heavy breathing filled the room.

"Again," Kael muttered.

He swung his sword down.

Boom—the air trembled slightly.

Kael wiped sweat from his forehead. "Still not enough..."

He put the sword aside and opened the book Nathan had given him earlier—a beginner’s introduction to mana flow. The pages glowed faintly under the lamp.

"So... apply mana only to the palm," Kael whispered, placing his hand forward.

A small spark flickered.

Pop.

The light vanished instantly.

"Tsk... let me try again."

He inhaled slowly, recalling how Nathan had explained mana as a "stream in the body."

He tried again.

This time, a thin layer of light coated his fingertips—small, unstable, but undeniably magic.

Kael stared at it in shock.

"...It worked."

He clenched his fist, feeling the slight warmth.

"If I can master this... I’ll survive."

He continued practicing—mana sparks, palm strikes, breathing techniques—until the moon was high and exhaustion finally pulled him down to the floor.

But before falling asleep, he smiled faintly.

"I’ll catch up... no matter how far behind I am."
