The clash between the Flame Hashira and the Upper Rank Three was not a duel.
It was a natural disaster compressed into the space of a ruined train yard.
From the shadows of the twisted metal, I watched a level of combat that finally, genuinely mirrored the monsters of the Grand Line.
Akaza did not wield a weapon.
He didn’t need one.
His fists broke the sound barrier with every strike, sending out localized, devastating shockwaves of blue pressure that cratered the earth.
He moved with a supernatural grace, his martial arts perfectly calibrated to deflect, evade, and counter every single swing of the Flame Hashira’s blade.
Beneath his feet, a glowing blue compass needle tracked every shift in the atmosphere.
He was reading Rengoku’s fighting spirit like an open book.
But Kyojuro Rengoku refused to be read.
The Flame Hashira stood his ground in the center of the storm, his bright yellow and red hair whipping around him like a raging inferno.
He didn’t retreat.
He didn’t yield an inch of dirt.
He met the Upper Moon’s fists with the blazing red steel of his Nichirin katana, swinging with such overwhelming torque that the air itself seemed to ignite from the friction.
“Magnificent!
Truly magnificent, Kyojuro!” Akaza laughed, a sound of pure, euphoric joy echoing through the freezing valley.
He leaned away from a sweeping horizontal slash that sheared the top of a boulder entirely in half.
“Your reflexes are perfect!
Your sword is beautiful!
But you are human!
You are bleeding, Kyojuro!” It was true.
The physical toll on the Hashira was devastating.
Every time Rengoku’s blade met Akaza’s bare flesh, the demon regenerated instantly.
A severed arm grew back before it even hit the ground.
A deep gash across his chest healed in a blink.
But when Akaza’s fists connected with Rengoku, bones cracked.
Flesh bruised.
Rengoku’s left eye was swollen shut, crushed by a glancing blow, and blood poured freely from a massive wound on his temple and several fractured ribs.
“Become a demon, Kyojuro!” Akaza begged, stepping inside the Hashira’s guard and delivering a brutal, concussive kick that Rengoku barely blocked with the flat of his blade.
“If you don’t, this beautiful technique will be lost forever!” “I will never become a demon!” Rengoku roared, his singular open eye burning with a terrifying, unshakeable resolve.
“Growing old and dying is what gives meaning and beauty to the fleeting span of a human life!
It is precisely because we age and die that our lives have value and nobility!” I gripped the hilt of my moss-green katana, my knuckles turning white.
I didn’t share Rengoku’s blinding optimism.
I thought his philosophy was reckless.
But as a swordsman, as a man who had sworn an oath to reach the heavens, I couldn’t help but feel a profound, burning respect for the sheer weight of his conviction.
He was staring down an immortal god of martial arts, his body breaking apart at the seams, and he was smiling.
“If you will not become a demon,” Akaza sighed, the smile fading from his lips, his golden eyes hardening into chips of cold ice.
“Then I will kill you right now.” The Upper Moon dropped his center of gravity.
The blue compass beneath him flared with blinding intensity.
The air pressure in the valley dropped so rapidly my ears popped.
He pulled his right fist back, condensing an impossible amount of kinetic and demonic energy into a single point.
Rengoku didn’t brace for impact.
He didn’t raise his guard.
He took a deep, ragged breath, pulling every last ounce of oxygen into his bleeding lungs, and lowered his glowing red blade.
His fighting spirit didn’t just flare; it erupted.
A massive, roaring aura of pure heat and pressure manifested around him, taking the shape of a colossal, blazing tiger.
“Flame Breathing.
Esoteric Art.
Ninth Form.” Rengoku’s voice was a calm, deafening thunder.
“Rengoku!” “Destructive Death: Annihilation Type!” Akaza roared.
They exploded toward each other.
The collision defied physics.
When the red steel of the Hashira’s blade met the condensed blue shockwave of the Upper Moon’s fist, a localized hurricane of dirt, fire, and kinetic pressure ripped through the valley.
The shockwave picked me up and threw me backward.
I dug my boots into the dirt, crossing my arms over my face as the debris shredded the air around me.
The noise was absolute, a deafening roar that vibrated right through my teeth and rattled my skull.
For ten agonizing seconds, the valley was entirely blinded by a massive cloud of pulverized earth and steam.
Slowly, the dust began to clear.
They were frozen in the center of a massive crater.
Rengoku’s red blade had bitten deeply into Akaza’s neck, cutting halfway through the Upper Moon’s spine.
Blood poured from the demon’s throat, splashing onto the ruined earth.
But Akaza had stepped inside the swing.
His right arm was driven forward, fully extended, aimed directly at the exact center of Kyojuro Rengoku’s solar plexus.
The killing blow.
The fist that would punch straight through the Hashira’s heart and spine, ending the life of a man who refused to yield.
[CRITICAL WARNING: The script demands a sacrifice.
Do not intervene.
Host erasure imminent if the primary narrative is fractured.] The yellow text flashed in my vision, accompanied by the blaring, agonizing siren of the Will of the World threatening to crush my organs.
To hell with your script, I thought, the furnace of my Iron Stomach burning hot.
I don’t let real swordsmen die for a stage play.
I stepped out of the shadows of the wreckage.
I didn’t draw the moss-green katana.
I drew the heavy, oak-stocked double-barrel from my right hip.
I didn’t have time to aim down the sights.
I fired purely from the hip, relying on thousands of hours of muscle memory.
I aimed slightly to the left of Rengoku, directly at the dense, tattooed triceps of the Upper Moon’s extended striking arm.
KABOOM!
The roar of the twelve-gauge shattered the stillness of the crater.
The heavy, sunlight-infused iron sand crossed the distance in a fraction of a millisecond.
Akaza’s skin was infinitely harder than Gokaku’s bone armor.
The Nichirin buckshot did not blow his arm off.
It didn’t even penetrate the muscle deeply.
But a twelve-gauge shotgun fired at point-blank range delivers a massive, undeniable kinetic shock.
Combined with the searing, corrosive burn of the sunlight ore striking demonic flesh, it forced the impossible to happen.
Akaza flinched.
His extended right arm, locked in a flawless trajectory toward Rengoku’s heart, jerked downward by exactly three inches.
The fist hit Rengoku.
The sound of tearing flesh and shattering bone echoed through the crater.
But because the trajectory had been violently shifted, the Upper Moon’s arm did not pierce the Hashira’s solar plexus.
Instead, it plunged through the lower left quadrant of Rengoku’s abdomen, tearing through muscle and intestine, but completely missing the vital organs of the chest cavity.
Rengoku coughed a massive spray of blood, his eye widening in shock.
Akaza blinked, staring at his own arm buried in the Hashira’s gut, utterly bewildered by the sudden deviation.
He snapped his golden eyes toward me, a look of pure, unadulterated fury crossing his face.
“You miserable little insect!
What did you just do?!” “I fixed your posture,” I grunted, cracking the smoking barrel open, ejecting the spent shell, and slamming a fresh one home.
Before Akaza could retract his arm to finish the job, Rengoku acted.
Despite the horrific, gaping wound in his abdomen, the Flame Hashira’s lips curled into a bloody, terrifying smile.
He dropped his left hand from the hilt of his sword and gripped Akaza’s trapped wrist with a vice-like strength that defied all biological logic.
With his right hand, he drove the red blade deeper into the demon’s neck.
“I will not let anyone here die!” Rengoku roared, blood pouring from his mouth.
Akaza panicked.
For the first time, the arrogant martial artist looked afraid.
Not of Rengoku, but of the horizon.
The dark purple sky was bleeding into a pale, terrifying orange.
Dawn was breaking over the mountains.
“Let go!” Akaza screamed, thrashing wildly.
He tried to swing his free left fist to crush Rengoku’s skull, but the Hashira caught that wrist too, locking the Upper Moon in a desperate, bloody stalemate.
The sun crested the ridge, a sliver of pure, golden light cutting through the trees.
Akaza shrieked like a cornered animal.
Driven by the absolute, biological terror of the sun, he didn’t try to pull his trapped arm out of Rengoku’s gut.
He violently planted his feet, twisted his torso with a sickening crunch, and ripped his own arms entirely off his body.
The Upper Moon tore himself free, leaving his severed limbs behind, and sprinted frantically toward the dark canopy of the forest, leaping into the shadows just as the sunlight flooded the crater.
Tanjiro hurled his black sword after the fleeing demon, screaming in a mixture of grief and rage, calling him a coward.
But I wasn’t looking at the fleeing Kizuki.
Kyojuro Rengoku dropped to his knees.
The severed arms of the Upper Moon turned to ash and dissolved, leaving a horrific, bleeding hole in the Hashira’s lower abdomen.
But his chest was rising and falling.
His heart was still beating.
He was bleeding out, and his career as a front-line combatant was likely over, but he wasn’t going to die today.
[WARNING: Major Narrative Deviation Detected.
The Will of the World is calculating…] [Calculation Complete.
The Protagonist’s emotional growth catalyst (The Hashira’s permanent incapacitation) remains partially intact.
The Will of the World accepts the compromise.
Host erasure averted.] I let out a long, ragged exhale, lowering the shotgun.
The pressure in the air vanished.
I had threaded the needle.
I walked slowly down into the crater.
Tanjiro and the others were surrounding Rengoku, crying and frantically trying to apply pressure to his wounds.
I gave them a wide berth.
I wasn’t a medic, and I didn’t do tearful emotional support.
My eyes were scanning the dirt.
Near the edge of the crater, where my shotgun blast had struck Akaza’s triceps, lay a small, jagged chunk of pale, tattooed flesh.
The Nichirin buckshot had cleanly sheared a piece of meat the size of an apple off the Upper Moon’s arm before he had fled.
I knelt down and picked it up.
It was heavy, pulsing with a terrifying, residual energy that made the hair on the back of my neck stand up.
The scent of it was intoxicating, a dense, metallic aroma that made the furnace in my gut roar with anticipation.
This wasn’t swamp water.
This wasn’t bone plating.
This was the flesh of the third strongest demon in existence.
I didn’t hesitate.
I shoved the chunk of Akaza’s meat into my mouth and swallowed it whole.
The Devourer’s Physique didn’t just activate; it violently detonated.
I hit my knees, clutching my chest as a surge of pure, agonizing power flooded my cellular structure.
My wiry frame violently expanded, the muscles tearing and instantly rebuilding themselves with terrifying density.
Thick, jagged black tattoos resembling Akaza’s own markings crawled up my arms and across my jawline.
My vision turned entirely blue, the sclera of my eyes darkening to pitch black.
The sheer physical rush was intoxicating.
I felt like I could punch a hole through the side of the mountain.
But it wasn’t just physical strength this time.
A strange, phantom sensation echoed in my mind.
Not memories.
I didn’t see Akaza’s past, and I didn’t suddenly understand his martial arts forms.
It was more like being handed a loaded weapon without an instruction manual.
I could feel a well of kinetic, demonic energy sitting in my chest, waiting for a release valve.
I stood up, my boots cracking the stone beneath me.
I pulled my right fist back, mimicking the stance I had watched Akaza use, and threw a straight punch into the empty air of the crater.
A pulse of blue light flared around my knuckles.
BOOM.
A jagged, chaotic shockwave of blue pressure erupted from my fist, traveling ten yards through the air before violently impacting the side of a boulder, blowing it to pieces.
It wasn’t the perfect, flawless snowflake-shaped shockwave of the Destructive Death style.
It was crude, wild, and incredibly inefficient.
I could feel that the energy required to produce that single blast was massive, operating at less than a twenty-five percent efficiency rate.
Without Akaza’s centuries of martial arts mastery to properly channel the Blood Demon Art, it was just a blunt, highly expensive kinetic shotgun blast.
But it was a ranged attack.
It was a manifestation of pure pressure that didn’t require me to swing a sword or reload a gun.
“Well,” I rasped, my voice distorted by the heavy demonic resonance, staring at my tattooed, pulsing hands.
“I guess I don’t need to learn a Breathing Style after all.”
