Kaguya’s breathing gradually became ragged, but his gaze grew even sharper.

He felt the sandai kitetsu trembling slightly in his hand, as if responding to his fighting spirit.

Arlong’s serrated longsword swung down with the sound of breaking air; Kaguya ducked low, and onikiri slashed upward diagonally, the blade clashing with the serrations in a shower of piercing sparks.

At the same time, Kuroobi’s Fish-Man Karate heavy punch arrived.

Kaguya suddenly exerted force with his feet, using “Shave” to retreat instantly, barely dodging the fatal blow.

Kaguya stepped repeatedly in the air, his figure suddenly soaring higher.

Chew’s water cannon grazed the soles of his shoes and blasted the wall behind him to pieces.

“Tempest Kick!”

Kaguya flipped in mid-air, and a sharp vacuum slash whistled out.

Chew hadn’t expected Kaguya to have such a means of attack and couldn’t dodge in time; he was struck in the chest by the slash, blood instantly splattering.

He groaned and staggered back, his eyes filled with horror.

The other Fishmen were also pale with shock.

They hadn’t expected this human to possess such strange techniques.

Kaguya seized this fleeting opportunity, the blade of onikiri glowing with an eerie blood-red light.

“One Sword Style: Blood Sakura!”

The blade’s light was as gorgeous as blooming cherry blossoms, yet it turned into a fatal killing intent the moment it touched Hachi.

Hachi blocked in haste, but two of his six swords were actually shattered by the blow, and blood seeped from the webs of his thumbs.

“Damn it!”

Arlong roared as he charged, his serrated sword sweeping across like a thousand-man army.

A flash of determination crossed Kaguya’s eyes.

The blade of the sandai kitetsu suddenly emitted a piercing hum, and blood-red demonic energy wrapped around his body like flames.

Instead of retreating, he advanced against Arlong’s attack.

The moment the blade collided with the serrated sword, the entire plaza trembled.

“Moonwalk!”

Kaguya suddenly changed his move, using the counterforce to leap into the air.

Kuroobi’s Fish-Man Karate shockwave grazed the edge of his clothes and blasted a huge crater into the ground.

“Tempest Kick: Chaos!”

Kaguya kicked his legs repeatedly in the air, sending several blue slashes pouring down like a rainstorm.

Hachi hurriedly raised his remaining four swords to block.

The sound of breaking metal rang out repeatedly, and all his weapons were destroyed.

“Impossible!”

Arlong’s eyes widened as he watched his subordinates fall one after another.

He swung his serrated sword in a rage, the blade tearing through the air with a sharp whistle.

The moment Kaguya landed, he performed “Shave,” his figure appearing behind Arlong like a ghost.

“One Sword Style: Yaksha!”

onikiri’s blade suddenly surged with a three-meter-long blood-colored sword qi.

Arlong turned in haste to block but was sent flying by the strike, crashing heavily into a distant building as the wall collapsed.

Amidst the dust, Kaguya stood with his sword, the demonic energy of the sandai kitetsu boiling.

He looked around; the Fishmen had fallen in heaps, and the remaining few were retreating in terror.

Kaguya gave them no chance to escape; with a few flashes of movement, he harvested them all.

Boom!

Arlong crawled out of the ruins.

Hachi picked up six weapons from other Fishmen and stood with Kuroobi.

The eyes of all three burned with the flames of anger.

Faint cracks appeared on Arlong’s serrated sword, but he didn’t care.

Instead, he flashed a hideous smile.

“Human, you certainly have some skill.”

Arlong licked the blood from the corner of his mouth.

“But do you think you can defeat us Fishmen like this?”

Kaguya didn’t answer.

He simply held onikiri across his front, the demonic energy on the blade growing even more intense.

He could feel his stamina depleting rapidly, but his gaze remained firm.

“Fish-Man Karate: Thousand Tile True Punch!”

Kuroobi suddenly lunged, his fist striking toward Kaguya’s face with the sound of breaking air.

“Six Sword Style: Octopus Pot!”

Hachi also launched an attack at the same time, his four swords blocking all of Kaguya’s escape routes.

“Water Cannon: Rapid Fire!”

Chew fired high-pressure water bullets repeatedly from a distance.

Faced with the three-way pincer attack, Kaguya took a deep breath.

A purple light flashed in his eyes as his Observation Haki activated.

“Six Powers: Paper Art!”

His body suddenly became as light as a piece of paper, skillfully avoiding Kuroobi’s heavy punch, while onikiri slashed toward Hachi at a bizarre angle.

“One Sword Style: Reverse Scale!”

The blade’s light was like a dragon; Hachi’s four swords snapped upon contact, and a spray of blood erupted from his chest.

Kaguya turned with the momentum, onikiri blocking Arlong’s serrated sword attacking from behind, sending sparks flying.

“Tempest Kick: Moon Ring!”

Kaguya suddenly raised his leg, and a crescent-shaped slash split Chew’s water cannon in two, continuing unabated toward the distant Chew.

Bang!

Chew was struck by the slash and crashed heavily into the wall, losing consciousness.

“Damn it!”

Arlong was furious, his serrated sword swinging wildly, each strike carrying a scream that tore through the air.

Kaguya used “Shave” repeatedly to dodge, but the stamina consumption began to slow his movements.

“Got you!”

Kuroobi suddenly appeared in Kaguya’s path of evasion, and a Fish-Man Karate heavy punch slammed hard into Kaguya’s abdomen.

“Pfft!”

Kaguya spat out a mouthful of blood, his body flying backward and breaking several stone pillars before stopping.

“Humans are just humans, after all!”

Arlong grinned hideously, his serrated sword held high, preparing to deliver the final blow.

Kaguya struggled to prop himself up, the blood at the corner of his mouth looking particularly vivid under the Moonlight.

The trembling of the sandai kitetsu grew more intense, as if urging him to continue fighting.

Kaguya took a deep breath, feeling the remaining strength in his body, and suddenly let out a cold laugh.

“You…

underestimate humans too much.”

Before his voice could fade, Kaguya’s figure suddenly vanished.

Arlong’s pupils constricted, and he instinctively blocked his chest with his serrated sword.

“Clang!”

The loud bang of metal clashing was deafening; the blade of the sandai kitetsu actually sliced right through the serrated sword.

Arlong looked at the broken blade in his hand in disbelief.

Before he could react, Kaguya had appeared behind him like a ghost.

“One Sword Style: Blood Moon!”

An eerie blood-colored blade light cut through the night sky, and a bone-deep wound instantly exploded across Arlong’s back.

He let out a roar of pain, his massive body crashing to the ground.

Kuroobi roared as he charged, the Fish-Man Karate shockwave tearing the ground apart.

Kaguya endured the intense pain and slashed the sandai kitetsu toward the shockwave.

The moment the blade met the shockwave, the air seemed to be torn apart, emitting a piercing explosion.

“Six Powers: Iron Body!”

Kaguya’s muscles instantly tightened like iron, forcefully withstanding Kuroobi’s full-strength blow.

His feet plowed two deep furrows into the ground, and blood overflowed from the corner of his mouth once more.

“Impossible!”

Kuroobi’s eyes widened.

“How could a human…”

“It’s not over yet!”

Kaguya suddenly lunged, onikiri’s blade glowing with an eerie purple-black light.

“One Sword Style: Ghost Cry!”

The blade light was like the wailing of a netherworld ghost; Kuroobi’s Fish-Man Karate stance was instantly broken.

He retreated in haste, only to see Kaguya’s figure suddenly split into three.

“Afterimages?!”

The real Kaguya had already appeared above him, the sandai kitetsu slashing down with the force of thunder.

Kuroobi raised both arms to block, but was sliced in half by onikiri.

“Kuroobi!”

Hachi charged out from the side, his remaining four swords turning into a silver storm.

The purple light in Kaguya’s eyes flared, his Observation Haki predicting the trajectory of every strike.

His figure moved like a swimming fish through the blade lights, the sandai kitetsu precisely parrying every attack.

“Clink clink clink clink!”

The sound of metal clashing was as dense as a rainstorm.

Suddenly, Kaguya caught a opening, and onikiri lunged like a venomous snake flicking its tongue.

“One Sword Style: Snake Bite!”

The tip of the blade pierced Hachi’s shoulder, drawing a spray of blood.

Hachi cried out in pain, and all four swords flew from his hands at once.

Just as Kaguya was about to take his head with a single slash, Hachi shouted.

“Wait a moment!”

onikiri stopped at Hachi’s neck.

“What is it?”

“I want to know, what kind of swordsmanship is that?

Why are there so many moves?”

“Nameless swordsmanship.

I just call them whatever.”

With that, onikiri slashed through Hachi’s neck.

Hachi had a look of disbelief on his face as he clutched his neck and collapsed to the ground.

From the ruins in the distance, Arlong stood up unsteadily, a mad rage burning in his eyes.

“A mere human…

dares to…”

Kaguya panted heavily, feeling his stamina nearing its limit.

“Fishmen…

will rule the East Blue after all!”

Arlong roared as he charged, his broken serrated sword still carrying a fatal threat.

Kaguya took a deep breath and suddenly assumed a strange starting stance.

The trembling of the sandai kitetsu suddenly stopped, and the surrounding air seemed to freeze.

“One Sword Style Secret Technique…”

Arlong’s attack was close at hand, but Kaguya’s figure suddenly blurred.

“Night Mara!”

In an instant, dozens of blood-red blade lights appeared in the plaza, enveloping Arlong like an interwoven spiderweb.

Every blade light struck precisely at a vital point, leaving bone-deep scars on Arlong’s body.

When the blade lights dissipated, Arlong remained frozen in his charging posture, dozens of blood arrows erupting from his entire body.

He looked down at his shattered body in disbelief and crashed to the ground.

A deathly silence filled the plaza.

Kaguya slowly walked up to Chew, and seeing that Chew was still playing dead, he delivered a slash to make his death real.
