In the blink of an eye, the "Mamaragan" erupted—an onslaught formed by merging Enel's Rumble‑Rumble Fruit powers with the massive thunderclouds generated by the Ark Maxim.
Lightning poured down in torrents, sweeping everything before it!
All of Skypiea was swallowed by the storm.
Those monstrously thick, violently raging bolts of lightning descended like the staff of heaven—divine punishment crashing onto the world itself!
The land of the Shandians and the seas of clouds that made up the sky island were blasted to pieces. Houses, buildings, streets, trees—everything was pulverized to rubble and dust in an instant!
Enel's manic laughter echoed from within the Ark Maxim.
"Ha‑ha‑ha‑ha‑ha! Ha‑ha‑ha‑ha‑ha!
"Grovel, you insignificant mortals, and witness the glorious deeds of a god!
"This is the beginning of Skypiea's annihilation!
"Fear the god, praise the god, worship the god!"
Yet at the very height of his arrogance…
Chiyu's Sharingan and Observation Haki had already pinpointed the Ark Maxim's weakness—its vulnerable spot, its fatal flaw!
With a cold snort, he amped his power to the absolute limit. The energy systems of two worlds fused and flowed together, becoming a single, world‑destroying sword aura!
He integrated ninja‑world chakra, ocular power, and ninjutsu with the Grand Line's martial arts and Haki, melding them into a power framework that belonged to him alone. Chiyu named it—
[Fire‑Sea Combat Form!]
A perfect battle mode that combines the power systems of Naruto and One Piece!
That single slash—unstoppable, world‑shattering!
It came crashing down, cleaving the Ark Maxim cleanly in two. The gigantic hull, unable to resist the unstoppable strike, split like rotten bamboo, explosions and shockwaves detonating one after another!
In the face of that blow, no "indestructible alloy," no "golden hull," no thundercloud weapon called "Mamaragan" meant a thing. All were worthless!
The Ark Maxim was utterly destroyed!
Instantly, the raging storm of ten‑thousand lightning bolts halted.
Only then did all the islanders realize that an extinction‑level catastrophe had been blocked by Chiyu. Each and every person felt the after‑shock of survival—an immense relief followed by boundless gratitude toward the heroic Marine from the Infinity Continent!
At the very peak of his triumph, Enel was cast from heaven to hell. With the Ark Maxim's ruin, his body was forced out of hiding and exposed once more!
"Damn it! You bastard!
"Uchiha Chiyu, you actually destroyed my Ark Maxim!
"This is sacrilege against a god!
"Even if you die ten thousand times, your sins won't be repaid!"
When Enel re‑emerged, many of his wounds were already half‑healed—clearly he had absorbed some stored energy from within the Ark and been reborn.
He roared, "Uchiha Chiyu! Do you think destroying the Ark means victory?
"The thunderclouds it produced still remain!
"Behold a power that eclipses even Mamaragan!
"Unlike that scattered barrage, this is the supreme might that can erase the entire sky island in an instant—my ultimate killing move…
"Perish with the thunder!
In that instant, every particle of thundercloud in the vault of heaven drew together, compressed, and warped into an incomparable dark‑golden sphere of lightning!
It was as though a cataclysmic thunderstorm had been condensed into a single ball of plasma. The violence and terror caged within were unimaginable!
Inside the colossal sphere, boundless lightning rampaged, swirling into vortices of current, yet not a sliver leaked out. Like a mountain‑sized ball of lightning, its power was utterly restrained, waiting to explode the moment it touched its target!
Even Rear Admiral Hina, Nami, and the others stared in dread, drenched in cold sweat.
"Th‑that thing is far too dangerous!
"If it touches the island's ground, it'll detonate instantly and wipe Skypiea out!"
Skyfolk and Shandians alike felt only fear and despair.
"He's gravely wounded, the Ark's gone, and he can still muster that strength?!"
"Save us, Chiyu-sama!"
Chiyu understood: this was Enel's death‑match strike, channeling every remaining ounce of the Ark's power. If Raigo landed, it really could obliterate the entire island.
He drew a deep breath.
His figure shot upward, streaking like a true hero toward the massive lightning sphere—defying heaven itself!
Gasps rose on every side.
Nami cried out, "Chiyu-sama, no!"
Rear Admiral Hina blanched. "Vice Admiral, w‑what are you doing?!"
The Marine troops gaped, scarcely believing their eyes. Skyfolk and Shandians shouted for him to stop, even knowing he was acting to save them.
Enel's brows knitted as he watched Chiyu surge toward Raigo.
"Seeking death, are we? Then have it!"
In the next heartbeat—
Chiyu plunged into the titanic sphere of lightning.
The world fell silent; even breathing seemed to cease. All eyes fixed on the dark‑golden orb high in the sky, and on the lone figure that had vanished within…
Inside Raigo, Chiyu's body was sheathed in Armament Haki to withstand the lightning's fury. Simultaneously, he cloaked himself in Lightning‑Release chakra, turning his body into lightning's kin, a part of the storm itself—so when he entered the sphere he did not trigger detonation!
If Raigo was an ocean of lightning, Chiyu was like a diver in an insulated suit whose body, too, was water—untouchable and unnoticed by the sea around him.
Only one who commanded both Armament Haki and Lightning‑Release could achieve this.
Enel's face twisted in shock. "Impossible! He's inside Raigo and it hasn't exploded—those raging currents can't even harm him?! Just what is that damn bastard…!"
Within the sphere, Chiyu wasted no time. Destructive as it was, any misstep here meant annihilation. Amid swirling electric vortexes, he raised his sword high—still in Fire‑Sea Combat Form, lightning chakra and Haki coiling together. A towering blade‑aura pierced upward, ripping open Raigo's domain and splitting its power apart!
Without hesitation, Chiyu swung the berserk sword‑aura again and again, slicing, carving, hewing, shattering the massive sphere until Raigo was hacked into tatters! Roaring bolts shattered into countless smaller balls, which split again into still‑smaller sparks until they vanished.
Chiyu finally re‑emerged, leaving a sky filled with thousands of human‑sized lightning orbs. Standing amidst them, he thrust a fist upward.
Behind him, ten thousand thunderballs detonated at once—
Explosions capable of sundering heaven and earth resounded—yet, dispersed into countless sparks and far above the island, their power no longer threatened Skypiea. They burst like celestial fireworks across the firmament, terrifying and breathtakingly beautiful all at once.
Amid that cascading thunder‑flower, Chiyu's silhouette became an eternal icon, branded into every heart.
Raigo was utterly undone.
Enel watched, and even he felt a pang of regretful dread.
"How can this be?! Is that man… the real… god?! N‑no! I'm destined to rule the sky and earth alike! I'll never lose to some intruder!"
With a furious roar, Enel unleashed every last shred of power—the ultimate technique, his supreme secret art:
"Two Hundred Million Volts: Raijin!!!"
His body dissolved, becoming pure lightning. He transformed into a gargantuan thunder god, reminiscent of Takemikazuchi—blinding arcs surging, impossible to gaze upon without risking blindness! A gigantic trident of lightning formed in his hand. In this ultimate state he possessed near‑perfect offense, defense, and might—each casual motion unleashing cataclysmic storms; every sweep of the trident incinerating all it touched.
"This is the final battle!" he thundered. "Uchiha Chiyu! It's you or me—one must die!"
Facing Enel's Raijin form, Chiyu instead allowed a rare smile.
"It'll be fun to kill you !"
