Chapter 155: Luffy: Crap… Did I Just Become a Legendary Mentor?!
"Worororo—!!"
Kaido's laughter rolled across the sky like muffled thunder. Even buried deep beneath the ground, his overwhelming presence still surged upward, shaking the clouds and making them churn violently.
"Huff… Kaido-sensei, aren't you going down yet?!"
Luffy hovered high in the air, breathing heavily, yet a satisfied grin spread across his face.
Drops of blood slid down his scar-covered limbs, tracing crimson arcs through the sky.
Before they even realized it, this life-or-death battle had already lasted for most of the day.
This kind of savage fight—no defense, nothing but trading blows with their lives on the line—had drained both of their stamina to the extreme. Their bodies were covered in wounds of varying severity, yet their fighting spirit still burned fiercely.
"Brat… let's decide this with one final move!!"
Before his words had even finished—
A deafening dragon roar erupted from deep within Onigashima.
A massive shadow burst through the smoke and dust, soaring into the sky as if riding the clouds.
—Kaido's Azure Dragon Form.
An ancient and supreme aura belonging to a higher lifeform swept across the heavens. As the colossal dragon stretched its body within the sea of clouds, its overwhelming pressure spread in all directions.
Violent winds howled.
Black clouds churned.
Lightning flashed and thunder roared.
Whoosh—!!
Blazing crimson flames suddenly erupted from beneath the dragon's scales.
The heat was so intense it seemed capable of vaporizing everything, the fire thickening into a magma-like viscosity under its terrifying temperature.
The flames surged skyward, turning the dark heavens crimson.
The surrounding air twisted from the heat, space itself trembling and warping. Even the light in the sky bent and refracted.
"Kaido… he's burning?!"
Standing amid the ruins, Yamato's pupils shrank in shock.
She had never imagined that her father could reach such a terrifying level of power.
That burning dragon was practically a walking natural disaster.
Thinking back to the hundreds of times she had challenged Kaido in the past, Yamato suddenly felt that her younger self had been unbelievably naïve.
"Boss Kaido…?!"
King stood frozen in place, his gaze locked firmly on the invincible figure soaring through the sky.
A colossal flame dragon that blotted out the heavens.
Endless flames spreading wildly.
Every scale gleamed with savage brilliance under the firelight.
—It was the most perfect and destructive being imaginable.
"Straw Hat boy…"
Kaido's dragon roar shook the world.
The giant dragon slowly opened its mouth, where flames and lightning intertwined violently.
"Take the title of 'the Strongest' from my hands!!!"
The enormous dragon raised its head and roared.
Its blazing body carried boundless power as it shot from the ground toward the heavens.
The atmosphere burst outward in ring-shaped shockwaves.
The momentum split clouds and shattered stone.
Even the heavens trembled under the pressure.
"My strongest attack, huh?!"
Luffy slowly raised his head.
His short black hair whipped wildly in the scorching wind, while fierce battle intent burned inside his crimson eyes.
Midair, he clenched his fist.
Armament Haki exploded forth instantly, coating his entire arm in jet-black hardness like deep-sea iron.
Conqueror's Haki surged violently around him, turning into black-and-red lightning that wrapped around his arm with destructive force.
Golden flames ignited at the same time, their brilliance driving away the darkness of the sky.
"Then bring it on, Kaido-sensei!!"
"BOOOOM—!!!"
The sky suddenly darkened.
A gigantic cross-shaped starburst exploded from Luffy's fist.
Black-and-red lightning surged wildly along his arm. Thunder roared like thousands of war drums.
The entire sky seemed illuminated by him alone.
This punch carried the destructive might to crush mountains and tear open the heavens.
Wrapped in thunder and flames—
It smashed downward!
"Flame Dragon Torch!!"
"Galaxy Impact!!"
BOOOOOM!!!
The explosion that followed shook the entire world—like thousands of nuclear bombs detonating at once.
Shockwaves filled with flames, lightning, and shattered stone spread outward in every direction across the sky above Onigashima.
Violent winds swept across the island.
Space warped and collapsed.
Light and sound were ripped apart.
Only pure destructive energy remained.
"That's insane… power on that level?!"
King's voice trembled uncontrollably.
Even from far away, the aura released by their ultimate attacks made his heart pound with fear and his scalp tingle.
Without exaggeration—
That force could punch straight through Onigashima and bury everyone along with it.
In the sky—
Luffy's punch forcefully overwhelmed Kaido's flaming dragon attack.
For a moment, the heavens seemed to collapse again.
The power was like a falling star system—unstoppable.
Kaido's enormous dragon body shattered piece by piece under the pressure. Scales exploded apart as blood and flesh rained down from the sky.
Yet—
Just as the punch was about to pierce through the dragon and strike Onigashima below—
Luffy suddenly realized something.
His fist could not move forward another inch.
"Straw Hat boy… I've lost!"
Kaido's eyes widened fiercely. Blood vessels burst across his vertical pupils.
Even with his body breaking apart, the remaining dragon's might still shook the heavens.
"But your punch… absolutely cannot land on Onigashima!!"
With the last of his strength, Kaido forcibly halted the descending attack.
Using his own body—
He protected the island and his remaining subordinates beneath it.
Luffy's eyes widened in shock.
Then a helpless grin appeared on his face.
"Crap… did I just become a legendary mentor?!"
The blinding light in the sky slowly faded like receding tides.
The space that had looked like a nuclear explosion began collapsing inward.
Fragments of shattered space glimmered like broken crystal, dissolving into nothingness.
Scorching heat waves spread outward from Onigashima, turning into invisible shockwaves across the sea.
Wherever they passed, seawater boiled into thick white mist.
After a long while—
Two blood-covered figures fell from the sky one after the other.
BOOM!
BOOM!
Two heavy impacts shook the earth.
Massive craters were smashed into the ground, dust and debris rising high enough to block out the sky.
Inside the craters—
Luffy and Kaido were covered in wounds deep enough to expose bone.
Their clothes were torn and soaked with blood.
Burn marks and impact scars covered their bodies. Even breathing sounded heavy and strained.
"Boss Kaido!!"
"Luffy!!"
Two desperate shouts rang out at the same time.
King flapped his flaming wings and shot down like a black bolt of lightning, landing beside Kaido and dropping to one knee.
His hand trembled as he reached out—yet he didn't dare touch Kaido's barely breathing body.
On the other side, Yamato rushed to Luffy's crater like a madwoman, her eyes red with panic.
King stared silently at Kaido.
The usually calm and cold Lunarian now radiated terrifying killing intent.
The air around him seemed to freeze.
Suddenly—
He raised his head.
His icy gaze locked onto Luffy.
King vanished instantly.
"I will never allow anyone to harm Mr. Kaido!"
His flaming blade slashed through the air toward the severely wounded Luffy.
The speed was so fast Yamato only saw a streak of red light.
She couldn't react in time.
But—
CLANG!!
A piercing metallic clash echoed.
A silver sword shining with cold white light blocked the flaming blade.
Sparks scattered everywhere.
The collision of their auras created a powerful shockwave.
King's gaze shifted toward the newcomer.
Silvers Rayleigh stood there calmly, his silver hair fluttering in the wind.
Flames surged around King as his power rose to the limit.
"Anyone who harms Mr. Kaido… must die!!"
Rayleigh smiled faintly.
"Sorry about that."
His eyes narrowed slightly.
"But that's my disciple."
"You're not touching him."
Yet King's expression didn't waver.
Instead, madness and resolve burned in his eyes. The flames around him intensified further.
He was ready to fight to the death.
But just as he was about to strike—
"That's enough… Alber."
A hoarse, exhausted voice sounded.
Kaido lay on the ground, breathing heavily.
Though his eyes still held frustration, there was no killing intent left.
"I lost."
"Hehehe!!"
Suddenly—
A cheerful laugh came from the nearby crater.
Luffy stood up.
He casually brushed dust off his body as if nothing had happened.
His wounds had somehow stopped bleeding.
Though his clothes were still torn, his complexion looked healthy and his eyes bright.
It was as if he hadn't been seriously injured at all.
Rayleigh, Yamato, King, and even Law in the distance froze in place.
Shock filled their faces.
King's pupils shrank violently.
After fighting Kaido all night and surviving that apocalyptic clash—
This kid could still stand up completely fine?!
…Isn't that basically cheating?!
"Worororo—"
Kaido looked at the boy before him and suddenly burst into hearty laughter.
There was relief in his voice… and even admiration.
"You really are an unbelievable brat… Come on."
"Kill me!!"
As the former Strongest Creature, Kaido would never accept living after defeat.
Only death in battle was worthy of him.
But unexpectedly—
Luffy simply grinned and waved his hand.
"Kaido-sensei, fighting you was… seriously awesome!"
"As for the rest—no need to say anything!"
He turned and looked at Yamato beside him.
Then he reached out and grabbed her hand.
Yamato froze instantly.
Two red blushes spread across her beautiful face like sunset light over jade.
Her crimson star-shaped eyes trembled with shyness and excitement.
Her heart pounded wildly.
"Alright, alright—let's go. Mission accomplished!"
Luffy raised a hand toward the sky.
The next moment—
A fluffy white cloud floated down from the heavens and stopped before him.
—A manifestation of Nika's imagination power.
This battle with Kaido had given him absurd gains.
Fruit Development:
85.2% → 87.9%
Even without fully activating Nika Form, he could now imagine simple objects into existence.
Things like:

"Th-this…?! Luffy, that's amazing!!"
Yamato's eyes sparkled with admiration as she threw herself into his arms.
Her long silver hair cascaded down her waist as she gazed up at him excitedly.
"Alright, alright, let's go!"
Luffy awkwardly pushed her away slightly.
He stepped onto the cloud and pulled Yamato up with him.
Kaido lay on the ground silently watching the young man.
His expression was complicated.
Soon—
The cloud slowly lifted into the sky, carrying the group away.
"Thanks, Kaido-sensei!!"
Luffy waved back with a bright grin.
"Worororo—!"
Kaido laughed loudly, though his tone sounded stubborn.
"Straw Hat brat… don't go thinking I taught you anything!!"
His laughter echoed across Onigashima.
Gradually fading into the distant sky as the cloud disappeared.
Thus—
The battle that shook the entire New World finally came to an end.
A decisive and exhilarating victory.
