Resonance: Awakening of the Unknown

Surpass Your Limit

The first day at Eclipse Academy’s Combat Division didn’t start quietly — it started with chaos.

“Form up! Three lines!”

Instructor Baek Gunho’s voice hit like thunder. Every student snapped to attention. Jiwoo fell beside Minjae, with a wooden sword in hand.

“I’m Instructor Baek Gunho,” he said, eyes sharp, tone harder. “S-Rank combatant. Former Vanguard. I’m not here to babysit. I’m here to see who deserves to stay.”

Whispers broke out.

“Wait, that Baek Gunho?”

“The Sword of the Red Dawn? He’s a legend!”

“Your first drill’s simple,” Baek said. “Survive.”

The floor panels opened with a hiss. Dozens of training dummies rose from hidden compartments, each armed with wooden swords.

“No mana. No armor. Only raw strength. Begin.”

Someone in the back raised a hand. "Sir, how long do we—"

"Until I get bored."

"What? Is he serious?"

"Without mana? We'll get killed out here!"

"That's insane—these dummies hit like a maniac!"

The dummies lunged.

Panic swept the lines — first-years shouting, tripping, blocking blindly. Jiwoo stayed still, lowering his stance. The noise faded, replaced by rhythm. Step, swing, breathe.

He met the first dummy’s attack, sidestepped, cut down. Another swung from the left; Jiwoo pivoted, countered, and broke its balance.

Seconds later, his dummy was down.

Baek’s voice cut through the air. “Han Jiwoo! Have you trained before?”

“Yes, sir. Kendo.”

Baek almost smiled. “That explains it. Keep that up.”

By the time the whistle blew, most students were lying on the floor, gasping. The field looked like it had just been through a war.

“You all move like you’re afraid to be hit,” Baek said flatly. “Confidence and having no fear to fight is the first thing you need to learn in this academy. Class dismissed.”

He turned, then added, “Wait Han Jiwoo, you stay here i have something to discuss with you.”

Minjae glanced at him, worried.

Jiwoo nodded.

“Go ahead.”

When the others cleared, Baek approached, tablet in hand. Jiwoo’s data flashed across it.

Han Jiwoo – Combat Class

Rank: E

Attribute: Dual (Unknown Secondary)

“Dual attribute,” Baek muttered. “E-rank, huh? Interesting.” His eyes met Jiwoo’s. “Jiwoo, do you believe that rank defines a person?”

“It doesn’t matter what I believe, sir,” Jiwoo said. “As long as I can fight, I’ll prove it.”

Baek grinned faintly. “Good answer.” He tossed a practice sword. “Then show me.”

Jiwoo caught it. “Sir?”

“What do you mean sir? or do you want me to slash you first before you start moving.”

"No sir."

"Then start moving."

They faced each other at the field’s center. Jiwoo inhaled, dropped into stance. Baek didn’t even raise his guard.

Then Jiwoo moved — fast, clean, precise.

Strike. Step. Counter.

Baek blocked every blow effortlessly. His eyes tracked Jiwoo's rhythm, reading each motion like a book.

“Good form,” Baek said, parrying another blow. “But you’ve hit a wall.”

“This is my limit, sir.”

Baek tilted his head, aura flaring. “Then break it.”

The next exchanges blurred — strike, step, pivot, clash. Jiwoo’s arms burned, but he refused to stop. Each strike is heavier than the last.

His breath hitched. That’s it. I’m done—

Then it came. The pulse.

The vibration under his ribs grew stronger, sharp, alive.

Violet light flickered along his blade.

Baek’s eyes narrowed. “What the hell—”

Jiwoo swung.

The air split. A black arc flashed across the field, silent and cold. It grazed the arena’s barrier, leaving a faint distortion before fading.

Baek moved in an instant, his mana bursting crimson. He blocked the slash, the shockwave cracking the floor and knocking Jiwoo flat.

Dust swirled. Baek lowered his weapon, eyes wide for a second, then sharp again.

“Void energy…? No, too stable.” He touched a faint cut across his cheek, blood trailing down. “E-rank, my ass.”

*** Minjae's POV ***

"W-what the hell…"

Minjae stood at the entrance, wide-eyed. He had come back out of curiosity — and now his brain couldn't process what he just saw.

"That's… Instructor Baek," he whispered. "And Jiwoo— he's fighting him? E-rank my ass!"

He rubbed his eyes, like that would change what he saw.

"And what the hell was that slash? That wasn't mana… it ate mana!"

Before he could think further, Baek turned toward him.

“Hey. You, by the entrance.”

Minjae froze. “Y-yes, sir?”

"Take him to the nurse's office."

Minjae blinked. "Me?"

Baek's gaze cut through him. "You're already here. Unless you want me to knock you unconscious too and I'll be the one who will put you two in the nurse's office"

"I'll take him now sir!"

Baek watched Minjae rush forward, dragging Jiwoo’s unconscious body away. When they disappeared, he glanced at the faint rip in the air, his voice low.

“That power… ”

---

When Jiwoo woke, the ceiling above him was white. His arms ached, his chest heavier than before. The faint scent of mana herbs filled the room.

“You’re up,” Minjae said beside him, grinning in relief. “Thought you were dead for a sec.”

“How long have I been out?” Jiwoo asked.

“Couple of hours. Instructor Baek told me to bring you here. He said you’re fine — physically, anyway.”

Jiwoo sat up slowly. “What happened?”

“You tell me,” Minjae said. “Why the hell are you fighting with Instructor Baek, and also the next thing is your sword’s glowing purple and eating his mana. That’s not normal, man.”

Jiwoo stared at the wooden sword on the table — faintly scorched along the edge. His hand drifted to his chest. The pulse was still there, faint but steady.

“Baek told me not to mention it to anyone,” Minjae added. “Said he’d handle it.”

“Not to mention it?” Jiwoo echoed.

“Yeah. Which usually means ‘something’s weird, and the teachers don’t want to panic.’” Minjae sighed. “Anyway, rest. I’ll grab food later.”

As he turned to leave, Jiwoo called softly, “Minjae.”

“Yeah?”

“…Thanks.”

Minjae smirked. “Don’t thank me yet. You still owe me for carrying your heavy ass across the campus.”

Jiwoo almost smiled. “I’ll add it to my tab.”

The door clicked shut behind him.

Silence filled the room again. Jiwoo stared at his hand, faint gold and violet flickers tracing beneath his skin before fading.

The same pulse. The same rhythm.

What are you?

His eyelids grew heavy.

When he opened them again, he was no longer in the infirmary.

Everything was black — no sound, no light. The air felt thick, like standing underwater.

His voice barely left his lips. “Where… am I?”

Something stirred in the dark.

And the pulse in his chest answered back.
