One Piece: Starting with Breathing Techniques

Kizaru's already gloomy expression darkened further. He glanced coldly at Kiro and suddenly laughed.

"I have to admit, Kiro, you're incredibly arrogant."

"But... this mechanical prosthetic limb will be more powerful than you imagine!" He made a fist with his right hand, and the blinding light spot was violently collapsed, turning from pure white to blazing gold, and finally condensing into a lightsaber.

"Unfortunately, the person whose hands are to be severed today is you!"

Akainu narrowed his eyes and sized up Kiro.

"You're Kiro?"

"That's so stupid!"

His right fist transformed into molten lava, the terrifying heat vitrifying the nearby ground. "The Revolutionary Army's Chief of Staff? He must die here today!"

Despite the threats from the two admirals, Kiro remained calm, gently stroking the blade of the Dragon Slayer Sword.

He silently fixed his gaze on the two figures in front of him, his mind churning with thoughts.

In the battle just now, he activated his mark and ended the fight with lightning speed. However, after killing Gringu Saint, the commander-in-chief of the Divine Knights, twice, Kiro suddenly felt an extremely terrifying presence watching him.

The icy feeling sent chills down his spine.

Considering that I am currently in Mary Geoise, this mysterious being could only be...

Im!

I'm afraid I'm already being secretly watched by Im. To avoid causing more complications and reduce the risk of Im taking action, the current battle must be ended quickly!

Without the slightest hesitation, Kiro's mind stirred, and bright red markings instantly climbed onto his cheeks, adding an eerie touch to his originally handsome face.

At the same time, the extremely sharp, invisible aura emanating from him suddenly contracted, gradually condensing and coiling around the longsword in his hand.

A deathly silence gradually fell between the three of them.

Three distinct auras collided and clashed, almost transforming into a tangible pressure that sent the rubble and gravel in the surrounding ruins flying and scattering.

In a split second, the three figures blurred and vanished from their original spot, transforming into three streaks of light invisible to the naked eye. They created layers of air waves as they collided with a deafening roar.

boom!

The longsword sliced ​​through the air and landed lightly on the giant lava fist.

Akainu felt an immense force coming from the swift sword blade, so strong that he couldn't help but take a half step back.

The longsword continued its momentum, and after repelling Akainu, it drew a snow-white blade of light in mid-air, instantly blocking the path of the Kusanagi Sword.

boom!

As the two longswords clashed, Kizaru's expression changed. He felt the strength in his hands inexplicably dissipate by nearly half, leaving him completely powerless to resist the opponent's strike.

"This is?!!"

A familiar feeling of unease rose within him... He had seen this power before!

Six years ago, during the fierce battle with Kilo on Vila Island, the enemy displayed this power in their final desperate counterattack.

At that time, this inexplicable force diverted half of his strength, which was the main reason why he suddenly suffered a setback, was seriously injured, and ultimately suffered a crushing defeat.

Now, Kilo has once again demonstrated that unforgettable power.

Moreover, aside from the influence of this power, Kiro's physique is now far superior to what it was six years ago.

The immense power emanating from the sword's edge forced Kizaru to retreat hastily, and the Ame-no-Murakumo sword in his hand cracked under the weight.

Kiro leaned forward, and as he placed his right hand on the hilt of his sword, the surrounding environment suddenly darkened.

"Clang clang clang!"

Three massive slashes suddenly appeared in the air, imprinted in front of Kizaru, slicing the Ame-no-Murakumo sword into the most basic particles of light.

With his perfect Observation Haki, Kiro twisted his right hand and blocked Kizaru's light-speed kick by a hair's breadth, then smoothly sliced ​​through the light cannon fired from the prosthetic arm.

The dull thud of a heavy blow echoed across the battlefield. Kiro was preparing to seize the opportunity when Kizaru's new energy had not yet been generated, but the intense heat coming from behind forced him to give up the chance.

"Haunted Dog!!!"

Akainu had appeared behind Kiro without anyone noticing.

His right arm suddenly swelled, the skin cracked, and crimson magma gushed out from the cracks, the dripping lava eroding the ground and sending up hissing white smoke.

With his five fingers together, the surging magma compressed and expanded in his palm, instantly condensing into a ferocious outline resembling a dog's head.

Almost instantly, the crimson light pierced through the air, its speed even surpassing the shrieking sound of the air being torn apart.

boom!

Kilo twisted his body to the side with all his might, barely dodging the terrifying, abyss-like pillar of magma. The scorching air rushed towards him, causing him to squint his eyes.

In the brief moment it took to dodge the Demon Dog, Kizaru had already gained a chance to catch his breath. He transformed into an elemental form, becoming a pure flash of light, and instantly moved away from Kiro.

"How scary, Kiro..."

Kizaru's expression appeared calm, but the web of his right hand, hidden behind his back, was trembling uncontrollably, still recovering from the powerful strikes he had just received.

It must be admitted that the pressure that Kiro brings to him now is far greater than before. After activating his mark, Kiro's pure strength has already surpassed that of him, a Marine Admiral.

Kizaru sighed, deciding to no longer hold back, and slowly spread his hands wide.

call out!

Several Yata no Kagami suddenly appeared beside Kiro, their rays intertwined and densely packed, blocking all possible escape routes for him.

His right hand had already re-formed the Kusanagi Sword, its tip pointing diagonally at Kiro.

Without any verbal communication, the dense beams of light suddenly converged the instant Akainu charged toward Kiro.

The mirrors from all directions simultaneously emitted blinding light, rendering the centrally located Kilo blind.

Just before Akainu's magma fist arrived, Kizaru's figure stepped out from the highest mirror, his Ama-no-Murakumo sword already raised high above his head, the blade leaving afterimages as it slashed downwards at supersonic speed.

Two terrifying attacks arrived at Kilo's face simultaneously, the surging air waves almost demonstrating their immense power.

Even with Kiro's current physique, he couldn't ignore such an attack; his Observation Haki sent out a needle-like warning in his mind.

All escape routes around them have been blocked, and no matter how fast Kiro is, he can't match Kizaru.

Caught off guard by this scene, the three men, including Big Bear, who were engaged in fierce combat not far away, broke out in a cold sweat.

Aokiji stopped fighting, his body radiating a chilling aura, the dazzling ice spikes dissipating, and he took off his sunglasses to look at the battle not far away.

"Kilo...has he become this strong?"

"..."

"Wait, what's this...?"

He looked toward Kilo, who was inside the ball of light, and saw several faint black and red arcs of electricity jumping around in the air.

The sky above had darkened at some point.

Black and red electric arcs... changing celestial phenomena...

"No way...?!"

Aokiji's eyes widened suddenly, and a bold guess popped into his mind.

……

Despite the imminent attack, Kiro remained calm and silently gripped the Dragon Slayer.

As he focused his mind, a vast and terrifying power gradually emerged and coiled around the Dragon Slayer Sword.

This aura was extremely domineering and powerful, radiating astonishing fluctuations, even distorting the air around Kilo.

Conqueror's Haki envelops you!!!

In addition, the sword intent did not dissipate, but instead wrapped around the sword body together with the completely different aura of the Overlord's Haki. The two terrifying auras merged and gradually became one.

Sword intent and Conqueror's Haki intertwine!

This was the first time Kilo had put this bold idea into action.

The moment the two colors intertwined, Kilo moved.
