Hundreds of miles beneath the surface, deep within the once-calm upper mantle, magma surged violently. The molten core-born magma mixed with regenerated magma from intrusive rocks—ultrabasic, basic, neutral, acidic, and alkaline—began to boil at the same time.
The violent trembling traveled upward through layers of stone. The crater beneath Uchiha Hikaru's feet—over a hundred meters wide—split open in an instant. Gray-black volcanic rock fractured like shattering ice, spreading jagged cracks and releasing a deafening roar, as if nature itself were screaming.
It felt like the volcano was furious, roaring at Hikaru for disturbing its slumber—red-eyed and ferocious.
"I've finally waited for this moment."
Without hesitation, Hikaru's pupils shifted from black to concentric rings of light purple—the Rinnegan. His hands formed a seal, and a transparent red aura erupted around him, glowing the same color as the cracks below and wrapping around his body.
"Flame Sealing Technique: Suction Seal!"
This sealing technique had been modified by Hikaru specifically for this purpose, designed to massively increase the absorption rate of fire-nature chakra—though it cut off absorption of all other chakra types.
A massive black skeletal frame expanded around him, rapidly forming a hundred-meter-tall demon-shaped Susanoo with burning wings. The red aura widened, completely engulfing the Demon Flame Susanoo.
"Sword, wake up. The buffet is here."
A familiar black mist flowed from Hikaru's right wrist. This time, it did not take human form—only swelling outward, covering the entirety of the crater.
"Since you're feeding me properly this time, I'll let go of the last incident."
The serious atmosphere shattered instantly at Sword's sarcastic tone, causing Hikaru's right eyebrow to twitch twice (╬ ಠ益ಠ).
This guy… he's still hung up on when I made him play support?
A sudden realization struck Hikaru. If Sword devoured all this again… wouldn't his physical form become even stronger?
Which meant—
BOOM!!!
The crater could no longer contain the magma below. It erupted violently, swallowing Hikaru in volcanic ash that shot thousands of meters into the sky. Hikaru no longer had time to think and could only pray his body would endure Sword's appetite.
The red shield shone brighter and brighter. A torrent of fire-nature chakra flooded into Hikaru's body like a runaway freight train, tearing through his chakra pathways.
His chakra pathways bulged, his skin flushed red, and ripping pain tore through him from the inside out, forcing him to grit his teeth.
"This fire-nature chakra… it's insane!"
He continued to circulate chakra, forcing the torrent upward toward his eyes. His eyes felt as if they were burning—like being thrown into lava. Yet at the same time the purple deepened, glowing faintly black-red, dazzling like a sunset.
The sky was drowned in gray and sulfur-yellow dusk—apocalyptic, terrifying.
In distant villages across the Land of Fire and the Land of Earth, the deafening roar was heard. People looked up to see a shattered horizon—gray-black clouds and burning twilight clashing like a broken painting.
But then—astonishingly—the thick cloud of ash began to break apart, dissipating unnaturally fast, as if brushed away by a god.
A child pointed upward, eyes wide.
"Grandpa, what's that? A giant with wings! Is it a monster from a volcano?"
The old man chuckled—until he looked.
His eyes widened. His lips trembled. He was speechless.
At the edge of the sky, a massive pair of dark crimson wings spread wide. Even from afar the armor and demonic silhouette were unmistakable—like a god of destruction descending to earth, flames flickering across his form.
The villagers trembled, frozen in terror. Legs refused to move.
But the child clapped in awe, jumping excitedly (≧▽≦).
"No! He isn't a monster—he's a god! Look! He blew away the dark clouds! He saved us from the volcano!"
The innocent voice and the clearing sky dispelled their terror. Slowly, they breathed again.
But Uchiha Hikaru could not rest.
The earlier eruption had been nothing more than a phreatic blast—steam pressure and expelled ash. That was only the beginning.
The true danger—the pyroclastic lava eruption—was still coming, and a single mistake could kill him.
Heat waves roared upward from below, warping the surrounding air.
BOOM!!!
The mountain trembled violently. Stone collapsed in avalanches. A dense swarm of blazing red magma shot upward toward him.
Hikaru raised his arms to shield himself, the Demon Flame Susanoo's wings folding around him like armor.
The natural chakra flowed into him relentlessly, the agony intensifying—but he felt his eyes reaching the brink of transformation.
"As I thought—natural chakra can accelerate the evolution of the Rinnegan!"
"But I can't digest magma. Only you can eat it."
Lava splashed against Susanoo's wings, losing its fire chakra and falling like dead rock.
Sword devoured it eagerly, intercepting the magma and stripping its valuable metals.
"Stop talking. I'm only eating the rare metals. I'm not eating those useless rocks."
Like a finicky kitten picking through fish bones ( ̄▽ ̄), Sword swallowed the magma, spitting out waste material.
Minutes passed. The eruption slowed, magma only gurgling at the crater edges before cooling into thick gel-like stone.
And now—Hikaru was trapped in an agonizingly unstable state…
