One Piece - Heaven Defying Comprehension!

The black-purple aura in Ace's eyes grew thicker, more violent.

Just as mastering Observation Haki to its highest level allows one to briefly "see" the future, Ace had unlocked the advanced skills of Conqueror's Haki through his heaven-defying comprehension.

Observation Killing!

Armament Killing!

Devil Fruit Ability Killing!

This was the advanced use of Conqueror's Haki, attained through sheer comprehension beyond normal limits. Ace could now use Conqueror's Haki to directly block the enemy's Observation Haki, Armament Haki, and even Devil Fruit abilities.

Those whose Haki wasn't strong enough were no longer even qualified to use it in Ace's presence. And for those who had not fully mastered their Devil Fruit powers, their abilities would be nullified by Ace's overwhelming Conqueror's Haki.

This is the power of a king! This is the supreme emperor!

Against such might, even an ant isn't worthy of throwing a punch at the king.

Ace's Conqueror's Haki had finally reached the summit of power in this sea!

This meant that Ace, relying solely on his Haki, now held the same strength as the Four Emperors of the New World. 

At this moment, Ace had truly earned the title of the most powerful man in these seas.

The black and purple aura in his eyes grew denser. Around him, the atmosphere roared with violent, boiling black and purple lightning.

"Bzzt! Bzzt! Bzzt!"

Rob Lucci and Jabra, expressions twisted in agony, felt the full force of the violent black-purple lightning that pierced their bodies, striking at every cell. 

The fear induced by this intense pain was unbearable for Rob Lucci and Jabra, both trained from childhood to be killing machines. All they could manage were pained, guttural roars.

But what terrified them more than the physical pain was the disappearance of their Devil Fruit abilities.

Devil Fruits—the mysterious treasures of the sea that granted extraordinary powers to those who ate them—were now completely unusable.

This sensation was different from being bound by seastone; it felt as if some unseen force had sealed their abilities entirely.

The terrifying truth became clear: Portgas D. Ace had the power to block their Devil Fruit abilities!

No, it wasn't just that—they weren't even worthy of using their Devil Fruit powers in front of Portgas D. Ace, the Fifth Emperor of the Sea.

There was no comparison between them and this man. 

Portgas D. Ace was like a true emperor, high above and untouchable. How could something so absurd happen?!

Rob Lucci gritted his teeth, blood spilling from the corners of his mouth.

Had he already resigned himself to a fight to the death?

To counter the power of Ace's Conqueror's Haki, he had activated his Zoan Cat-Cat Fruit—Leopard Form early, assuming his hybrid human-animal state.

But why?! Why did it end like this?!

Even with his Devil Fruit powers, he couldn't use them against Ace. 

How could such a thing be possible? Was the gap between them truly this vast?

Rob Lucci's eyes were filled with both physical and emotional pain—not just from the violent black-purple lightning, but from the realization that the gap between him and the top powers of the sea was this immense.

He was so far beneath Ace that he wasn't even worthy of fighting to the death.

Is this the emperor of the sea?

High above, reigning supreme over the entire ocean?

At this moment, Rob Lucci finally understood the true weight behind the title, "Emperor of the Sea."

How ridiculous had he been, thinking he could fight to the death and make Ace pay some price, even if it cost him his life?

With a sorrowful laugh, Rob Lucci slowly unclenched his fists, his head hanging low.

He had surrendered to the overwhelming power of Ace's Conqueror's Haki.

"Lucci! Jabra! Stop, stop joking around! Hey! Stop joking!" 

Kaku shouted, eyes bloodshot, staring in disbelief at Lucci and Jabra—both returned to their human forms, heads bowed, completely defeated under the onslaught of violent black and purple lightning.

Although Kaku had always looked down on Jabra, their strength was almost the same. Jabra had even eaten the Zoan Dog-Dog Fruit in its wolf form, and after transforming, his power surpassed Kaku's own.

And Lucci!

Lucci! The strongest among them!

Despite being rendered helpless the last time he faced Ace's terrifying power, Lucci possessed the strength of the Cat-Cat Fruit, transforming into a monster when using his Devil Fruit.

Both Lucci and Jabra had come here ready to die, determined to make Ace pay—even if with their lives.

But what now?!

They hadn't even truly fought yet!

Lucci and Jabra—both Devil Fruit users—had their abilities blocked by Ace's Conqueror's Haki!

They had surrendered without even putting up a fight!

No matter how Kaku roared, neither Lucci nor Jabra responded. They stood limp, heads hanging low, bodies stilled under the black-purple lightning, as though in reverence.

"!!!"

The blood drained from Kaku's eyes, replaced by ultimate fear.

He remembered that feeling of powerlessness, the same as when he had faced Ace back in Water 7. The overwhelming pressure that told him even the smallest movement would lead to his destruction.

"Ah!" 

Kaku clutched his head and let out a desperate scream.

Bzzt!

A branch of black-purple lightning shot down from the sky, forming a shadow that pierced Kaku's body.

"Ugh!"

Kaku's head jerked back mechanically, eyes filled with unbearable pain. His mouth opened as if to speak, but no words came out.

With one final look of agony, his eyes rolled back, and he collapsed unconscious.

"Kaku! Lucci! Jabra!"

Fukurou's face was a mask of horror.

By power levels, Kaku, Jabra, and Lucci were the strongest in CP9.

And yet, before they even engaged in combat, they were utterly defeated by Ace's Conqueror's Haki.

Is this Conqueror's Haki? Is this what it means to be an emperor?

The weight of that title!

Bzzt! Bzzt! Bzzt!

Once again, the black-purple lightning in the atmosphere split into three more branches, the air twisting in response to the violent, constantly shifting weather.

"Shave! Move, damn it!"

Fukurou screamed internally, but despite his mastery of the technique, he couldn't move.

Bang!

As he stared into the abyss of despair, a black-purple lightning bolt struck Fukurou's body.

"No… stop struggling. We don't even have the right to resist anymore."

Next to him, Kalifa let out a bitter laugh before losing consciousness.

"Is this truly the power of an emperor? It's no joke…"

Even Kumadori, pierced by the black lightning, could no longer keep up his usual light tone.

With his last bit of strength, he attempted to strike a dignified pose.

"Even if this is the end, let me go out with some pride."

With a final wave of his hand, Kumadori fainted.

"Cha ba ba!"

Fukurou, pierced by the lightning, stared in pain as his vision blurred.

He tugged at the zipper on his mouth, his eyes rolling back as he too succumbed to unconsciousness.

Boom!

As Fukurou collapsed to the ground, CP9 had been utterly defeated.

Franky, along with his subordinates and the giant duo, Oimo and Kashii, stood frozen, mouths agape. In the vast expanse of Enies Lobby, only they and Spandam remained standing.

This was CP9—the secret intelligence force that operated directly under the World Government, an elite unit not officially recognized within CIPHER-POL's ranks. And yet, facing Ace, they hadn't even been given the chance to fight back.

In an instant—just a glance—and all of CP9 had fallen. Was this the power of the man called the Fifth Emperor of the Sea?

Franky's mind reeled. This was Enies Lobby, a fortress of absolute justice for the past 800 years. Not a single innocent verdict had ever been issued here; no one who set foot on this island returned alive. And now, it had been brought to its knees?

It was as if he were dreaming.

"No... this is the man that our captains chose to follow. This is Flame Emperor [Portgas D. Ace]," Oimo muttered in awe.

"We now sail under the banner of the Flame Emperor, a man capable of shaking the very foundations of the world," Kashii's eyes shone with excitement. Only a man of this magnitude could rightfully claim the seas as his domain.

"Ace." 

The girls, their eyes gleaming with admiration, gazed at the raging storm of black and purple lightning swirling around them. Ace's Conqueror's Haki had grown even more formidable, more intense than when they had last witnessed his clash with Admiral Aokiji.

They knew. In this moment, Ace had surpassed the world's mightiest forces—the Admirals of the World Government. He now stood on a level above them, a realm reserved only for the most powerful.

This was their captain, a man beyond compare. The girls smiled, their lips curving in quiet triumph.

"Hey, hey, this can't be happening…"

Spandam stood rooted to the spot, his body trembling. His limbs felt like ice, as if he'd fallen into an arctic abyss. His back was drenched in cold sweat as he stared at the fallen forms of his subordinates, his mind unable to comprehend the reality before him.

"Fukurou! Kalifa! Blueno! Kaku! Jabra! Lucci!" Spandam's voice cracked in disbelief.

"You can't be serious! You're all elite agents, masters of the Six Powers! CP9's finest!"

"Lucci! Jabra! You both even consumed Devil Fruits, the rarest treasures of the sea! How could you fall so easily?! Stand up, damn it! Stand up!"

Snot and tears smeared Spandam's face as he screamed and kicked at Lucci and the others in a desperate rage.

Normally, Lucci and the others—who barely tolerated Spandam as their superior—would have subdued him with a murderous glare. But now, no matter how much he shrieked and flailed, none of them stirred.

As reality slowly settled in, Spandam's fury turned to panic. He stumbled backward, weakly colliding with debris, then collapsed to the ground.

"How... how could this happen?!" Spandam's voice quivered with terror. "Why were my powerful subordinates defeated in an instant?! This has to be a nightmare!"

A surge of black-purple lightning suddenly crackled in the air, a tendril of it slowly inching toward Spandam.

"No... no, stay away!" he shrieked, dragging his body backward in a clumsy attempt to flee, tears and snot streaming down his face.

This was it—the power that had overwhelmed his most formidable agents, the power that had left even the killing machine, Lucci, writhing in agony. 

Spandam, realizing he had no other choice, desperately clutched at his final hope—the golden Den Den Mushi in his coat.

"That... that's...!"

Robin's eyes widened in horror as she recognized the golden phone.

"Stay back!" Spandam screamed, pressing the button in a fit of panic.

Click.

The moment he pressed it, the advancing black-purple lightning halted in front of him, then dissipated.

Spandam sat frozen for a moment, staring at the golden phone in his hand. His face twisted with terror as realization dawned.

"It's over... it's over!" Spandam howled, clutching his head in despair.

The Buster Call was activated!

---

Marine Headquarters.

Beep! Beep! Beep!

For the first time in nearly twenty years, the silver Den Den Mushi, used exclusively for receiving Buster Call signals, emitted a sharp, piercing sound.

"This... this is a Buster Call!" A Marine soldier trembled, his voice filled with alarm.

"A Buster Call has been initiated! It's coming from Admiral Aokiji's golden den-den mushi!" another soldier confirmed in shock.

"Alert all departments immediately! Prepare the Buster Call fleet!"

Once a Buster Call was launched, it could not be stopped. It was an absolute order, a manifestation of the World Government's unyielding order.

"Contact the ten battleships stationed at Water 7! Each ship must be manned by a thousand elite soldiers! And inform the five Vice Admirals on Buster Call duty: Vice Admiral Momonga, Vice Admiral Yamakaji, Vice Admiral Onigumo, Vice Admiral Momousagi, and Vice Admiral Tokikake!"

A quick check revealed the location of the signal.

The Marine soldier's throat went dry. "The location of the Buster Call signal is..."

"Where? Hurry up! We need to mobilize immediately," his companion urged.

"The signal... it's coming from Enies Lobby!"

---

Spandam's voice cracked as he screamed once more, "It's over! Enies Lobby is going to be destroyed!"

Buster Call!

Robin's eyes filled with sorrow as memories of Ohara resurfaced, the island consumed by the flames of the Buster Call, its people annihilated. That nightmare—the darkest shadow in her life—was once again being relived.

Just as Robin, overwhelmed by emotion, prepared to act, she felt a warm embrace.

Her tear-filled eyes met Ace's calm gaze.

"Your nightmare, the Buster Call... let me be the one to break it for you, Robin," Ace whispered gently, his smile full of warmth.

Tears welled up in Robin's eyes as she nodded softly.

"Yes..."
