Transmigrating as an Extra, But the Heroine Has Regressed?!-Chapter 337: Fights of the Saber!

"Master," she said again, her head still bowed low, white eyes calm and unwavering.

"Huh?"

Both Yumi and Kael stood there like idiots.

Their brains refused to process what they were seeing.

"Master?" Kael repeated dumbly, pointing at himself. "Me?"

The Saber girl lifted her head slowly.

Her eyes—once crimson with killing intent—were now a clear, glowing white. There was no hostility left in them.

"To me," she said simply.

Yumi's jaw dropped.

"I was defeated by you," the Saber girl continued.

"In this dungeon, defeat means recognition. Recognition means submission. Therefore—" she placed her fist over her chest, armor creaking softly, "—you are my master."

Kael opened his mouth. And then closed it.

Ran a hand through his blood-matted hair.

"This dungeon is insane," he muttered. "I swear, it's actually insane."

Yumi leaned closer to him and whispered, "… did you accidentally adopt a Rank A Saber?"

"I did not try to," Kael whispered back. "It just… happened."

Before either of them could say anything else—

The dungeon responded.

The air above them rippled.

A deep, ominous hum echoed from the ceiling.

Kael's instincts screamed.

"Move—!" he shouted.

Too late.

From high above, a red-colored demon core dropped.

It fell with terrifying speed, trailing crimson light like a falling star.

It slammed directly onto the second armored soldier who had been standing motionless since the beginning.

CRACK.

The core shattered on impact.

Red light exploded outward.

The soldier's armor began to vibrate violently. Cracks formed instantly, glowing with seething crimson energy. Long strands of hair spilled from beneath the helmet, flowing wildly as if caught in a storm.

Her body straightened.

Her head lifted.

Two eyes opened—

Glowing blood-red.

The pressure that erupted from her made the previous Saber feel like a warm-up.

Yumi staggered back, her knees almost giving out.

"…This one," she whispered in horror, "is different."

The red-eyed Saber moved.

She vanished from the stone platform above and reappeared midair, descending like a falling executioner.

BOOOOOM.

She landed directly in front of Kael and Yumi, the impact shattering the floor and sending a violent shockwave outward.

Kael barely managed to stay on his feet.

Yumi was thrown backward, skidding across the stone.

The red-eyed Saber slowly straightened.

Her long sword slid free from its sheath with a sound that cut straight through Kael's bones.

She didn't speak.

Her killing intent alone crushed the air, making it hard to breathe.

Kael clenched his fists.

They were exhausted.

His mana was nearly empty.

Yumi was barely standing.

And yet—

There was no retreat.

He took a long breath.

"Master," the white-eyed Saber said, stepping forward and placing herself in front of Kael without hesitation. "I shall fight for you."

Kael blinked.

"…Okay," he said tiredly. "But don't call me master."

The Saber hesitated for half a second.

"…Understood," she replied.

Yumi stared at her back.

"…She's really on our side," Yumi murmured.

"Yes," Kael said quietly. "Looks like it."

The white-eyed Saber drew her blade fully, white light flowing along its edge.

"I was defeated," she replied calmly. "You were not. That is the difference."

The red-eyed Saber's lips curved slightly.

Then—

She disappeared.

CLANG!

Steel collided with steel as the white-eyed Saber barely managed to block the strike. The impact was catastrophic.

The shockwave blasted outward, throwing Kael and Yumi back several steps.

The white-eyed Saber skidded across the ground, boots carving deep lines into the stone.

"…So strong," Yumi gasped.

The red-eyed Saber pressed forward relentlessly.

Her sword strikes were faster.

Heavier.

Each swing carried overwhelming force, smashing against the white Saber's guard and slowly breaking it down.

Kael forced mana into his legs and lunged forward.

"Astral Punch!"

He drove his fist toward the red-eyed Saber's side.

She didn't even look at him.

Her elbow slammed backward.

BOOM.

Kael was sent flying, crashing into a pillar hard enough to crack it in half.

Blood sprayed from his mouth.

Yumi screamed.

She transformed partially, claws extending as she leapt at the red-eyed Saber from the side, slashing with everything she had left.

Her claws struck—

And bounced.

Sparks flew.

The red-eyed Saber turned and backhanded Yumi midair.

CRASH.

Yumi hit the ground hard, rolling several times before stopping, coughing violently.

"Yumi!" Kael shouted, forcing himself up despite the pain.

The white-eyed Saber charged again, unleashing a flurry of precise strikes—cut after cut, each aimed at vital points.

The red-eyed Saber blocked them all.

Then countered.

Her blade flashed once.

The white-eyed Saber's armor shattered at the shoulder, blood spraying as she was thrown backward violently.

She barely managed to land on one knee.

Kael stood between them again, sword shaking in his grip.

"Dark Edge!" he roared, pouring the last of his mana into the blade.

The shadowy figure formed behind him once more, smaller than before but still terrifying.

He swung.

The red-eyed Saber raised her sword.

The clash shook the entire level.

The shadow shattered instantly.

Kael's sword flew from his hand.

He was thrown back like a broken doll.

Yumi tried to stand again—

And failed.

The red-eyed Saber walked forward slowly.

Unharmed. 𝑓𝑟ℯ𝘦𝓌𝘦𝘣𝑛𝑜𝓋𝑒𝓁.𝑐ℴ𝓂

Unstoppable.

Even together—

They were no match.

The white-eyed Saber forced herself to stand.

Yumi said quietly. "This opponent exceeds us."

Kael wiped blood from his lips, forcing a grim smile.

"…Yeah," he replied. "I noticed."

Steel screamed.

That was the first sound Kael heard as the two Sabers collided—one bathed in white light, the other drenched in crimson killing intent. Their blades met not like weapons, but like laws clashing against each other.

The white-eyed Saber moved first.

She stepped in with perfect footwork, her sword drawing a clean arc aimed straight for the red-eyed Saber's neck.

Her movements were refined, elegant—every strike calculated, every angle precise. She was no longer the statue guardian of the dungeon. She was a true warrior.

The red-eyed Saber answered with brutality.

Her blade came down like a falling executioner's axe.

CLANG—!

The impact cracked the stone beneath their feet. The white Saber was forced back three steps, her boots grinding trenches into the floor as her arms trembled from the sheer force.

"…So heavy," she muttered, tightening her grip.

Kael watched from the side, barely able to stand, his vision blurred with blood and exhaustion.

"This isn't a duel," he thought grimly. "It's a massacre waiting to happen."

The white Saber surged forward again, unleashing a rapid series of cuts—thrust, slash, reverse cut—each one aimed at joints, gaps, weak points in the red Saber's armor.

The red Saber blocked them all.

Not with finesse.

With overwhelming dominance.

She didn't dodge.

She didn't retreat.

She crushed each strike head-on, her sword moving with terrifying weight. Sparks burst violently with every collision, lighting the chamber like explosions.

Then—

The red Saber kicked forward.

BOOM.

The white Saber was thrown across the arena, crashing into a broken pillar and shattering it completely. She rolled to a stop, coughing blood, her armor cracked in multiple places.

Yumi cried out, forcing herself up again despite her injuries.

"No—don't die—!"

She charged, claws glowing faintly with dark mana, aiming for the red Saber's blind side.

The red Saber turned casually.

Her elbow struck Yumi's chest.

CRASH.

Yumi slammed into the wall, her beast form flickering violently as she slid down, barely conscious.

Kael clenched his fists until his nails cut into his palms.

"…I can't move," he realized. "My body's finished."

The white Saber stood again.

Blood ran down her arm.

Her breathing was heavier now.

But her eyes were steady.

She raised her sword and pointed it directly at the red-eyed Saber.

"I will not fall," she declared. "Not before my master."

The red Saber's lips curved into something like a smile.

"So you chose a human," she said coldly. "Then fall with him."

She lifted her sword.

The air changed.

Mana did not surge.

It condensed.

The crimson glow around her blade collapsed inward, becoming dense, sharp, absolute.

Ancient runes ignited along her sword, symbols that burned directly into the air itself.

Kael felt it instantly.

His heart skipped.

"…That presence," he whispered. "That's not Rank S."

The white Saber's eyes widened.

"…No," she said softly. "That is beyond."

The red Saber spoke a single word.

"Mythic Caliburn."

The dungeon screamed.

A pillar of crimson light erupted upward, piercing the ceiling of Level Thirty as if the dungeon itself were paper. The sword in the red Saber's hands transformed—its outline blurring, its length extending, its edge glowing like a fragment of a dying star.

Reality warped around it.

The white Saber rushed forward without hesitation, pouring everything she had left into one final charge.

Their swords met.

For a heartbeat—

Nothing happened.

Then—

BOOOOOOOOOOM—!!!

The explosion erased the sound.

The shockwave tore through Level Thirty, annihilating walls, pillars, and the arena floor itself.

The ceiling collapsed in a violent cascade of stone and crimson light.

The white Saber was engulfed.

Yumi screamed.

Kael felt himself lifted—

Then thrown.

His consciousness shattered as the dungeon gate burst open under the force, ejecting him like debris from a collapsing world.

Darkness swallowed everything.

When Kael opened his eyes—

He was lying outside the dungeon gate.

Cold stone beneath his back.

Faint light above.

His body felt distant, numb, as if it no longer fully belonged to him.

The gate behind him was cracked.

"Level Thirty…i will come back"
