Chapter 15:

Kazuma, Unleashed

I Got Isekai’d With No Magic or Skills, But My Body Is Monstrously Strong

While Ren charged toward the pirate boss, Kazuma was already deep in battle.

He fought where the thugs were thickest—cutting through them one by one with deadly precision. To him, they were nothing more than small fries.

Kazuma wasn’t just another adventurer. He was a talented swordsman, trained for years, once nearly ranked at the top of their entire guild. These kinds of fights? This was where he thrived.

But just as he cut down another thug— Thwip.

A kunai came flying from the shadows.

Kazuma barely dodged. It grazed his cheek, drawing a thin line of blood.

His eyes darted around.

Another kunai. This time, he deflected it with his sword.

From the crowd, a new figure emerged—silent, cloaked, masked. A ninja.

Kazuma’s instincts screamed.

This one wasn’t like the others.

Stronger. Quieter. More dangerous.

“You only good for cutting down weaklings?” the ninja taunted, stepping into view.

Kazuma tightened his grip on his swords.

“A real warrior doesn’t hide in shadows.”

The ninja chuckled.

“A real warrior doesn’t need to announce his presence.”

And then he charged.

By now, most of the fighting had shifted to nearby alleys and fields. Here, it was just Kazuma and the ninja.

Their blades met with a metallic clash— Clang! Clang!

Steel struck steel as they tried to overpower each other. Kazuma had the strength. But the ninja had speed.

Then, without warning, the ninja vanished into the smoke.

Kazuma’s eyes scanned the battlefield.

Too late.

Slash.

A quick cut across his leg. Kazuma stumbled.

He spun, only for the ninja to disappear again.

Another flash.

Slash. This time across the back.

Kazuma winced, blood soaking into his shirt. The ninja was too fast—appearing from one direction, striking, and vanishing again before Kazuma could react.

“Tch...!” Kazuma grit his teeth, slashes piling up.

All around them, the village was still a warzone—Rachel, Alex, and Melissa were locked in their own battles. There was no help coming.

Kazuma fell to one knee, bleeding from his arms, legs, back.

He stared at the dirt, panting.

“What kind of swordsman am I… if I can’t even beat the first opponent who’s actually strong?”

“Was I only fighting weaklings all my life?”

He clenched his jaw.

“I can’t let this be my end.”

Closing his eyes, he took a deep breath.

“A true warrior doesn’t rely only on his sight… he learns to sense what others can’t.”

The ninja came again—rushing in from the shadows for another kill.

This time, Kazuma moved—just in time to dodge the blade.

The ninja clicked his tongue, frustrated. He struck again, even faster.

But Kazuma didn’t rely on his eyes anymore.

He felt the air shift.

The presence.

The intent.

The blade came, aimed straight for his heart.

In a flash, Kazuma twisted his body—letting the sword pierce shallowly into his side, blood pouring instantl—but he caught the ninja’s arm with his own.

Tight. Unyielding.

The ninja’s eyes widened in panic.

He tried to pull back—tried to wrench his blade free.

But Kazuma wouldn’t let go.

Not this time.

The ninja was stuck—his blade lodged in Kazuma’s side. His body had lunged forward, aiming for Kazuma’s heart, but now his momentum had betrayed him.

Kazuma, breathing heavily, glared into the ninja’s eyes.

It wasn’t over.

With a sudden surge, Kazuma raised his right leg and slammed it into the ninja’s left knee with brutal force.

“AAAHH!” the ninja screamed as his leg bent at a sickening angle.

Kazuma didn’t stop.

Again. And again.

He kicked the same leg mercilessly, smashing bone against bone, until the ninja collapsed—howling in agony, clutching at his shattered limb.

The one who had danced in shadows... now couldn’t stand.

Kazuma stepped back, breathing hard, blood soaking through his side. The slashes all over his body throbbed—but he didn’t flinch.

He picked up his swords, still stained from earlier clashes, and walked slowly toward the downed ninja.

This time, it would end with one blow.

But then—

“Kazuma!!” Melissa’s voice rang out, full of panic.

His head snapped toward her.

Across the field, she was cornered by a towering samurai—his katana raised, poised to strike.

Kazuma didn’t think.

He moved.

With everything left in his body, he charged forward. His wounds burned with every step, but he didn't stop—not until he slammed into the samurai from the side, knocking the man off balance and sending him sprawling.

The samurai scrambled to his feet and retreated, disappearing into the chaos.

Melissa gasped, kneeling beside Kazuma as he collapsed to one knee.

“You idiot…” she whispered. “You’re all cut up.”

“Heh… you’re my teammate, aren’t you?” Kazuma replied, grinning weakly.

Melissa immediately began healing him. Her hands glowed softly, but her face twisted in strain—the wounds were deep, and it took all her mana to stabilize him.

Kazuma, half-conscious, looked toward the spot where he’d left the ninja.

Empty.

Even with a broken leg, the assassin had used the distraction to escape.

Kazuma let out a dry chuckle and sighed.

“Maybe next time…”

Meanwhile, not far from the burning shrine—

Ren and the pirate boss were locked in a furious fistfight.

Each blow shook the ground beneath them.

The pirate boss swung a savage uppercut, but Ren ducked under it.

He went low, aiming a sweeping kick at the man’s legs—but the boss jumped back just in time.

Then, without warning, the pirate stepped in close—his elbows snapping forward, followed by a brutal knee to Ren’s gut.

Ren hit the dirt hard, coughing.
