The eastern mountain village of Shirakawa didn’t look like a hunting ground.
It looked like a graveyard.
Thanks to my profoundly dysfunctional sense of direction, a journey that should have taken two days had stretched into five.
I had somehow managed to cross a river that wasn’t on any map, accidentally scaled a sheer cliff face while looking for a shortcut, and ended up arriving from the north instead of the west.
By the time I walked through the wooden gates of the village, the sun had already set, casting long, skeletal shadows across the empty dirt roads.
There was no wind.
There were no crickets.
The paper doors of the humble wooden houses had been violently smashed inward, leaving gaping black maws that swallowed the moonlight.
The stench of dried blood and rotting marrow hung in the cold mountain air, so thick it felt like I was breathing underwater.
I drew my moss-green katana with my left hand and unholstered the sawed-off Nichirin double-barrel with my right.
I didn’t have to search for the demon.
He was waiting for me in the center of the village square, sitting atop a gruesome pile of human remains like a king on a throne of garbage.
He was massive, standing easily over seven feet tall.
But it wasn’t his size that made my combat instincts scream; it was his skin.
He was completely encased in thick, overlapping plates of white, calcified bone armor.
It covered his chest, his arms, and formed a terrifying, jagged skull-helmet over his head.
Only his eyes were visible—two burning, blood-red orbs filled with malicious amusement.
“Another slayer,” the demon rumbled.
His voice sounded like grinding stones.
“The crows keep sending me appetizers.
Are you here to avenge these fragile little twigs?” “I’m here because I’m hungry, I’m tired of walking, and you’re in my way,” I said, my voice deadpan.
I didn’t wait for him to monologue.
I raised the shotgun, aimed directly at his center of mass, and pulled the right trigger.
KABOOM!
The roar of the twelve-gauge shattered the silence of the village.
The cone of fire and sunlight-infused iron sand crossed the distance in a millisecond, striking the demon dead in the chest.
In my previous encounters, this was the part where the demon shrieked in agony as the iron sand shredded their cellular structure.
This time, there was only a loud, metallic CLANG.
Sparks showered across the town square.
When the smoke cleared, the demon was still sitting on his pile of bones, entirely unbothered.
The Nichirin buckshot had violently pitted the white bone armor, leaving scorch marks and shallow craters, but it hadn’t penetrated the plating.
The shrapnel hadn’t reached his flesh.
“Tickles,” the demon chuckled, slowly standing up.
His heavily armored joints cracked with a sickening sound.
“My name is Gokaku.
My Blood Demon Art allows me to compress my own skeleton into an exoskeleton harder than diamond.
Your little toy stick is useless here, boy.” I narrowed my eyes, breaking the shotgun open to eject the spent shell and immediately sliding a fresh one into the chamber.
“Diamond, huh?
Good thing I know how to cut hard things.” I exploded forward, my boots kicking up a cloud of dirt.
I dropped my center of gravity, gliding across the square with zero wasted motion.
I closed the gap in a fraction of a second, bringing the moss-green katana up in a brutal, two-handed vertical slash aimed directly at the unarmored gap beneath his jaw.
Ittoryu: Thirty-Six Pound Cannon.
Gokaku didn’t even try to dodge.
He simply raised his forearm, catching the edge of my blade directly on his bone-plated bracer.
The impact sent a shockwave of kinetic feedback straight down my arms.
My wrists screamed in agony, the fragile bones of Genya Shinazugawa’s body violently protesting the sheer torque.
The green steel of my sword sparked and whined, but it didn’t cut through.
“Too light,” Gokaku sneered.
He backhanded me.
I saw the strike coming, but my nerfed body simply wasn’t fast enough to disengage.
The massive, bone-plated fist slammed into my ribs like a battering ram.
The sound of my own bones shattering was deafening.
I was launched backward, flying through the air like a ragdoll.
I crashed through the front wall of a nearby house, shattering the wooden support beams, and rolled violently across the tatami mats before slamming into a stone hearth.
I coughed, a massive glob of hot blood splattering onto the floorboards.
My vision immediately blurred, the edges of the room turning dark.
My left arm was completely numb, hanging limply at my side.
My shotgun had been knocked out of my right hand during the flight, lying in the dirt ten yards away.
I tried to push myself up with my good arm, but a crushing weight pinned me to the floor.
Gokaku had crossed the distance instantly.
He stood over me, his massive, armored foot planted squarely on my shattered chest.
Every time I tried to inhale, the jagged edges of my broken ribs ground against my lungs.
I was suffocating on my own blood.
“Is this the limit of the Demon Slayer Corps?” Gokaku mocked, leaning down, the bone-helmet inches from my face.
“You lack the physical strength to scratch my armor.
You lack the speed to evade me.
You are nothing but a fragile bag of blood waiting to be emptied.” He raised his right arm, the bone plates shifting and extending into a jagged, lethal spike.
I glared up at him, my vision swimming.
He was right.
This body was failing me.
The shotgun was a gimmick, the sword was too light, and the physical parameters of this vessel were pathetically low compared to the East Blue.
I couldn’t brute-force my way through a diamond-hard defense without my original muscle density.
If I relied on Genya Shinazugawa’s baseline stats, I was going to die right here on this dirty floor.
The Will of the World wouldn’t save me.
The System wouldn’t save me.
But I was Roronoa Zoro.
And I refused to die because of bad biology.
If my sword couldn’t cut him, and my gun couldn’t break him…
I would just have to use the one weapon this body inherently possessed.
As Gokaku brought the bone spike down toward my throat, I didn’t try to block it with my broken arms.
I violently thrust my head forward, ignoring the agonizing pain in my chest, and clamped my jaw directly onto the only unarmored piece of flesh I could reach: the soft, grey tissue exposed at the joint of his inner elbow.
Gokaku froze.
“What are you—” I didn’t let him finish.
I bit down with every ounce of jaw strength I had cultivated over a lifetime of biting swords.
My teeth sank deep into the demonic flesh, severing veins and muscle fibers.
I forcefully ripped my head backward, tearing a massive chunk of bloody, pulsing meat right out of his arm.
I swallowed it whole.
Gokaku let out a scream of pure, confused horror, stumbling backward and clutching his bleeding joint.
“You bit me?!
You filthy animal, what did you just do?!” I didn’t answer him.
I couldn’t.
The moment the demon flesh hit my stomach, the world stopped spinning.
It didn’t feel like eating poisoned fish or raw tree bark.
It felt like swallowing a live grenade.
The ‘Iron Stomach’ trait, dormant and starving for true fuel, violently awakened.
It didn’t just digest the flesh; it weaponized it.
The corrosive, highly toxic cells of Kibutsuji Muzan that ran through the demon’s blood were instantly broken down by my hyper-metabolism, converting the demonic toxicity into pure, unadulterated biological energy.
A terrifying, burning heat exploded outward from my core, flooding my veins like liquid magma.
My shattered ribs snapped back into place with a series of sickening, violent cracks.
The numbness in my left arm vanished, replaced by a surge of overwhelming power as the torn muscle fibers forcibly knitted themselves back together.
My heart slammed against my ribcage, pumping thick, oxygen-rich blood at a speed that would have exploded a normal human’s arteries.
I slowly pushed myself off the floor.
The floorboards groaned under my feet.
My wiry, fragile frame began to swell.
The muscles in my arms, shoulders, and chest expanded, packing themselves with an unnatural, hyper-condensed density that perfectly mirrored the Asura-like physique I had spent years building in my previous life.
Black, jagged veins crawled up the sides of my neck.
When I opened my eyes, the sclera had turned a deep, demonic black, and my irises burned with a golden, predatory light.
I looked at my hands.
I flexed my fingers, feeling the terrifying, raw, explosive torque coiling in my wrists.
“What…
what are you?” Gokaku stammered, taking another step back, his red eyes wide with absolute terror.
“Your aura…
you smell like one of us!” “I have a very fast metabolism,” I growled.
My voice sounded different—deeper, layered with a harsh, demonic resonance that vibrated the air itself.
I stepped out of the ruined house.
I didn’t walk; I simply appeared in the center of the square.
The temporary speed boost was astronomical.
I reached down and picked up my dropped moss-green katana.
It didn’t feel heavy or fragile anymore.
It felt like a feather.
“Diamond armor,” I mocked, falling into a low, predatory stance.
“Let’s test it.” Gokaku roared in a panic, crossing his arms over his chest to reinforce his bone plates.
“Blood Demon Art: Impenetrable Fortress!” I didn’t use a Breathing Style.
I just used pure, overwhelming, demonic physics.
I planted my foot so hard the dirt street cratered beneath me.
I swung the katana.
Ittoryu: Lion’s Song.
There was no spark.
There was no resistance.
With the demonic strength multiplier amplifying my perfect technique, the green steel sheared through the diamond-hard bone plating like a hot knife through warm butter.
The top half of Gokaku’s torso, bone helmet and all, slid neatly off his lower body.
He didn’t even have time to register the pain before his head hit the dirt.
His red eyes stared wildly at me as his body instantly began to crumble into grey ash.
“Impossible…” his disintegrating mouth gasped.
“A human…
a human ate me…” I stood in the center of the quiet square, breathing heavily.
The intense, burning rush of demonic energy was already beginning to fade, my body rapidly returning to its normal, wiry state.
The black veins receded, and my eyes returned to normal.
My chest ached—a phantom pain from the shattered ribs—but the wounds were completely healed.
I spat a glob of foul-tasting demon blood into the dirt, wiping my mouth with the back of my sleeve.
It tasted like rotting garbage, but the results were undeniable.
I finally had a way to bridge the gap in this world.
Suddenly, a crisp, metallic chime echoed in my mind, distinct from the frantic alarms of the Will of the World.
[System Notification: Host has successfully triggered the hidden genetic parameter of the designated vessel.] [Trait: Demonic Ingestion seamlessly synchronized with Host trait: Iron Stomach.] [Calculating integration…
Success.] [Unlocking Host Status Panel.] A sleek, translucent blue interface materialized in my field of vision, completely ignoring my attempts to swat it away.
[Name: Roronoa Zoro / Genya Shinazugawa] [Title: The Stray Asura] [Current Vessel Condition: 100% (Healed via Demonic Ingestion)] [Breathing Style Aptitude: 0%] [Active Buffs: None] [Unique Mechanic Unlocked: The Devourer’s Physique] [Description: By consuming the flesh of a demon, the Host can temporarily overwrite the vessel’s biological limits.
Stat multipliers, regeneration speed, and demonic traits gained are directly proportional to the strength of the demon consumed.] [Warning: Excessive consumption without adequate rest may result in temporary cellular instability.] I stared at the floating text, reading the words carefully.
“The Devourer’s Physique,” I murmured out loud, a slow, dangerous grin spreading across my face.
I didn’t need water dragons.
I didn’t need to blow up ceramic gourds or master constant breathing.
The Will of the World wanted me to play the role of the angry, talentless outcast?
Fine.
I would play it perfectly.
If this universe wouldn’t give me the strength to cut through my enemies, I was just going to eat them alive.
