Chapter no.12 Squire of Oscar vs The Stray Demon

0-0-0-0-0-0-0-0-0-0-0-0

[Name: Asylum Demon]

[HP: 1900 / 2,195]

Naruto gripped the Astora straight sword tightly in his hand, his knuckles turning white as he stared down the demon just a few meters away. In his other hand, he clenched something else, hidden in his closed fist—a smoke bomb, ready to spring his trap. The demon's face had a chunk missing now, thanks to the plunge attack he'd landed, just like Oscar.

"At least now I don't have to throw up when looking at you, dattebayo," Naruto muttered, forcing a grin that felt more like a snarl.

The demon shifted, its massive form tensing up, eye narrowing as it prepared to leap at Naruto. He saw it in its stance—You're gonna try the same move again? Fine. Let's play.

Naruto threw the smoke bomb to the ground, and a thick cloud enveloped the arena. The demon took the bait, lunging straight into the smoke, just as planned. He didn't have to see it to know what was coming—the thunderous sound of its hammer swinging down confirmed it.

As the smoke thinned, Naruto saw the demon's monstrous form breaking through, hammer raised high. That's when his clones moved, their shield formation snapping into place. The hammer came down hard, colliding with the shields.

And then—boom!

The moment the hammer hit, every single clone exploded.

The plan was simple. Naruto had attached explosive tags to his body, knowing that when he used the Shadow Clone Jutsu, everything he wore—including the explosive tags—would be copied onto his clones. This meant each clone was a walking explosive trap, primed to go off when popped. Even though the yield of the clone explosions was weaker than the actual yield of the original explosive tags, the sheer number of clones made up for the reduced power.

The blast threw the demon backward, the shockwave tearing through its massive body. Its hammer—that damn hammer—shattered into pieces, fragments flying everywhere. The force was so strong that the demon stumbled back, arms flailing, its ugly head jerking wildly.

Before it could even process what had happened, Naruto hurled a fuma shuriken from behind one of the pillars. He watched it spin through the air, slicing straight toward the demon's face in a perfect arc. Just a little more...

The demon's head jerked back, and Naruto shouted, "Kai!"

The flashbangs attached to the fuma shuriken erupted with a blinding light, igniting the arena like a miniature sun. The demon let out a guttural howl as the brilliant flash seared its vision, stumbling backward, its massive hands flying up to clutch its face in agony. The deafening sound of its pained roars echoed through the arena, sending tremors through the ground.

The demon thrashed wildly, disoriented, its heavy footsteps shaking the ground beneath Naruto's feet.

"Now!" Naruto roared, his voice cutting through the chaos.

From the second floor, two clones stood tall, their eyes locked on the target. On either side of the arena, hidden in the forms of pots, more clones revealed themselves, their hands glowing with pyromancy flames.

The fireballs flew in unison, streaking across the arena like meteors, each one finding its mark on the demon's body. The impact was brutal—flames swallowed the demon whole, wrapping around its flesh, consuming it in an inferno.

The demon roared to the heavens, its cries like the wails of a beast being torn apart from the inside. The fire ate away at its skin, charring it black, the flames dancing like serpents around its body.

Blood poured from the demon's wounds, thick and dark, like rivers of molten metal. The fire seared its way through the flesh, turning muscle and bone to ash.

And through it all, Naruto stood there, watching the flames do their work, feeling every moment as if it were his own heartbeat.

[Name: Stray Demon]

[HP: 900 / 2,195]

Naruto's eyes flicked up to the name hovering above the demon, the text that had changed with a finality he couldn't ignore.

The asylum demon had destroyed the chains that once held it down, chains forged by Lord Gwyn himself to bind the demon's soul, forcing it into obedience. Those chains kept the beast as the final obstacle for the chosen undead, containing it so its true power wouldn't turn the Northern Undead Asylum into a smoldering ruin.

But now... those chains were gone.

The beast wasn't bound anymore—it was just a stray demon now, consumed by rage and the memory of its home.

Flames licked at its charred skin, embers glowing across its massive body, almost as if the fire itself was alive. The demon's body, blackened with soot, seemed to pulsate with heat, like it had been born in the heart of an inferno. And maybe it had—maybe these flames reminded the demon of its home. Izalith, the land of fire. The land where it had been captured and enslaved by Gwyn's army.

The demon's eyes locked onto Naruto.

For a moment, he felt the weight of that gaze—ancient, filled with anger, with pain, with something far more powerful than he was ready for. But he didn't flinch. Naruto gripped the Astora straight sword in his right hand, while his left held the crest shield firmly in place.

The demon raised what was left of its hammer, the once-great weapon now little more than a crude staff. Naruto braced himself, double-handing his shield in front of him, ready for the strike.

I'm ready. Come on, you bastard, make your move.

But then... it didn't attack.

Instead, the demon slammed its staff into the ground with a force so powerful that the floor beneath them crumbled. Naruto's eyes widened in shock as the ground gave way, and before he could react, he was falling—they were falling—into the darkness below.

They crashed into the basement of the asylum, Naruto's feet barely touching the ground before he stumbled, struggling to regain his balance. The room was massive, a circular chamber with a weathered, stone floor cracked and uneven. Broken tiles lay scattered everywhere, and stone pillars loomed around him, some shattered into pieces, others standing like silent sentinels.

The walls stretched high, built from aged stone blocks that were crumbling with time, moss creeping up their surfaces like nature's fingers reclaiming what was hers. A faint light filtered through the gaps, casting long shadows across the floor. Naruto looked around, his breath catching in his throat when he realized the truth. This was it. The entire asylum was built around this chamber—the demon's cage.

Naruto's mind raced as he tightened his grip on the Astora straight sword, his knuckles turning white. I need to keep my eyes on those spells. That's what worries me most about this demon. Just as he was bracing himself for the next move, the demon lunged, swinging its massive staff in a wide horizontal sweep.

His heart sank. There's no room to dodge. The basement was too small, the space too cramped. Naruto knew he couldn't outrun that attack. Damn it!

In an instant, he used the Substitution Jutsu. The staff hit the spot where he'd been, detonating the explosive tags he left behind on the substitution log.

Boom!

The explosion shook the chamber, filling it with smoke and debris. For a split second, Naruto let himself hope that maybe he'd destroyed the demon's staff.

But then, through the thick smoke, the staff came swinging once more, almost unaffected. The explosion had only delayed it for a fraction of a second. The demon was back on him, faster than he could react.

Did it... did it just figure out my substitution jutsu?

A cold realization hit him.

The substitution only works over a few feet. From point A to B. If someone knows where point B is, they can time their attack to land right when you reappear.

And that's exactly what the stray demon had done.

Naruto barely had time to lift his shield before the staff connected. The force of the blow was like nothing he'd ever felt, a crushing impact that sent him airborne. His shield arm shattered instantly, the bones snapping like twigs. He felt his ribs cave in, sharp splinters piercing through his side. The pain shot through him like a lightning bolt, spreading to his chest as his lungs screamed for air.

He crashed into a pillar with a sickening thud, feeling his spine twist and his head whip back, his vision swimming with darkness and stars. His legs crumpled under him as he slid down the pillar, his whole body feeling like it was on fire. Breathe, just breathe, he told himself, gasping for air that wouldn't come, each breath like knives stabbing into his ribs.

The demon's staff hit the ground again, and Naruto knew what that meant. His pulse spiked.

Oh no... not that attack.

Forcing himself up, his whole body screaming in protest, Naruto staggered toward the nearest corner of the room. His hands were shaking so badly he could barely open the pouch at his waist. He didn't care what pills he grabbed; he just stuffed as many as he could into his mouth, chewing them like they were his last lifeline. Stamina boosters, painkillers, chakra pills—anything to keep him conscious, to keep him from blacking out.

The demon raised its staff high, and Naruto saw the glowing orb forming at its tip—an orb of fire, purer and hotter than anything he'd ever seen. His own pyromancy flames were nothing compared to this. The orb pulsed and expanded, growing brighter and hotter until it exploded in a massive shockwave of fire.

The heat hit him first, a searing wave that made his skin feel like it was peeling off. Naruto barely threw himself into the corner before the blast reached him. All my clones... they would've been wiped out if they were too close to the explosion. If only they'd been outside the radius, they'd have survived.

Adrenaline and hormones coursed through his veins, setting his whole body on fire, his nerves screaming with pain and energy all at once. He felt like his heart was going to explode out of his chest, his muscles twitching with the urge to keep moving, to keep fighting, to survive.

And then he saw it—the demon's face. It was grinning. Enjoying this. Enjoying watching him struggle, watching him suffer.

Oh, that made Naruto's blood boil. His vision went red, and he felt a vein throb in his forehead. You think this is funny, you overgrown barbecue? He gritted his teeth, forcing himself to his feet despite the pain that tore through every inch of him. You haven't seen anything yet.

Naruto's senses were on high alert as he kept a tight grip on the Astora straight sword, adrenaline coursing through him like lightning. The stray demon reared back, its grotesque body tensing as it prepared a brutal stab with its massive staff. Way of Focality was on overdrive, heightening his perception, slowing everything down as he analyzed the demon's every move. He could see the exact angle of its attack, the precise moment the staff would pierce the ground.

Without hesitation, Naruto jumped, the air rushing past him as the staff shot beneath his feet, narrowly missing him. He landed on the staff's shaft with perfect balance, his feet steady on the twisted wood. He dashed up its length, adrenaline burning like fire through his veins, and leaped into the air, bringing the Astora straight sword down in a heavy downward slash aimed right at the demon's eye.

The blade met its mark with a sickening crunch. Dark, thick blood splattered from the demon's eye socket as the sword dug deep, blinding one of its massive eyes. It roared in agony, the sound echoing in the chamber like the tortured wail of a beast in hell. Naruto felt the vibration of the roar run through his bones, rattling his insides, but he didn't stop.

The demon twisted, snapping its jaws at Naruto, trying to devour him whole. He was ready for it. One of his shadow clones launched him backward just as the demon's mouth closed in, exploding with a deafening boom inside its gaping maw.

Chunks of flesh and teeth sprayed from the explosion, the demon's lower jaw ripped apart into a gruesome mess. Blood poured from the open wound, drenching the floor beneath it in dark liquid. The demon's roar was now a garbled mess of pain, more like a guttural growl than anything resembling a scream.

Naruto stuffed more pills into his mouth, barely chewing as he forced them down. Come on, body, heal faster! He gritted his teeth, shoving the pain to the back of his mind. He needed to keep moving. He couldn't afford to slow down now.

He saw the demon slam its staff into a nearby pillar, feeling the energy building near the center of the room. It's a spell—it's trying to set up another blast. The staff slam was a distraction, and he knew it. Naruto bolted, trying to get outside the blast radius.

Too slow.

The red orb exploded, sending a shockwave that hit Naruto like a freight train. He was flung off his feet, the ground spinning out from under him as he slammed into the floor, the impact rattling his bones. His helmet saved his skull from cracking open, but his vision blurred, and he tasted blood.

The sound of wings flapping filled his ears. Naruto looked up just in time to see the demon lifting off the ground, its massive wings beating the air, only to fold them in as it prepared to dive-bomb him.

Fat bastard is going to squash me like a bug, Naruto thought, his fingers already flying through the hand signs for the Substitution Jutsu. At the last second, he vanished, but he didn't leave behind a log or stone this time.

No, he left behind a very special gift—a fuma shuriken, glinting in the dim light as it spun up toward the descending demon. It landed right in the worst possible spot—the demon's rear end.

The impact was grotesque, the fuma shuriken lodged deep in the demon's hindquarters. Naruto didn't even have time to savor the moment before he shouted, "Kai!" activating the explosive tags wrapped around the shuriken.

The explosion was catastrophic. The blast ripped through the demon's lower body, tearing apart its insides. A mess of blood, entrails, and what looked like shredded organs sprayed out in all directions. The demon's guts spilled out in a steaming pile on the ground, the smell so foul it made Naruto's stomach lurch. Its butt region was obliterated, shredded beyond recognition.

Naruto swallowed hard, trying not to vomit at the sight, but he couldn't tear his eyes away from the mess he'd created. Part of him felt a flicker of sympathy for the monster, but then he remembered Oscar's words—his precept burned into his mind: "Precept number fifteen: Do not show sympathy for the enemy, for they shall show you none when you fall."

Naruto clenched his jaw, his resolve hardening. No sympathy for a beast that would have torn me apart without a second thought.

But then he heard it—the flapping of wings again. His muscles tensed, ready to defend himself, but he saw something that made his blood boil. The demon wasn't coming back for a fight. It was trying to fly away.

"Oh, hell no," Naruto snarled, eyes blazing with fury. "You're not getting away, not after everything you've done!"

Naruto watched as the demon shot out of the hole like a massive, flaming boulder, and he knew he had to act fast. His muscles tensed as he channeled chakra into his legs, feeling the surge in his thighs and calves that powered his jumps. He launched himself upward, pushing off the cracked ground with everything he had. Not enough. The demon was too fast, already climbing higher, but he wasn't going to give up. Not now.

One after another, Naruto's clones formed beneath him, their hands locking together to fling him higher and higher. Each one threw him further into the air like a human slingshot. The wind rushed past as he soared, adrenaline pounding in his ears as he finally found himself above the demon, the entire scene blurring for a split second as he caught a glimpse of its burning wings beneath him.

This is it.

Without hesitation, Naruto pulled two kunai from his pouch and hurled them with all his strength. The blades tore through the demon's wings, ripping into the charred flesh with sickening precision. It roared, spiraling downward, losing control as Naruto gripped Astora's straight sword with both hands. Gravity did the rest, pulling him down with incredible speed, the sword poised for a final, crushing blow.

But the demon wasn't finished. As he closed in, Naruto saw it point its staff directly at him. A red orb began to form at its tip, growing larger, more intense. He knew this was it—the moment that would decide everything. Either he'd win, or he'd be nothing but ash in a crater.

No choice. Naruto channeled chakra into the explosive tags strapped to his back. They detonated in a deafening blast that should've torn him apart, but Oscar's armor—his armor—saved him. The explosion flung him forward, propelling him with enough force to break through the demon's defenses.

Naruto screamed as he brought the sword down, his blade connecting with the red orb just as it was about to explode. Fire engulfed him instantly, the heat so intense he thought it would melt him from the inside out. His skin screamed, his nerves went numb, and he could feel every fiber of his body wanting to give out.

But he didn't.

Maybe it was Oscar's armor protecting him, or maybe it was sheer willpower. Either way, Naruto knew without looking at the system window that he was down to his last bit of strength—One HP. One last hit. His body felt like it was falling apart, but he didn't stop. The roar that escaped his throat wasn't just from pain; it was everything—every struggle, every loss, every push forward. It felt like Oscar himself was with him, pushing him to keep going, to not give up.

Naruto's blade hit the demon with all the force he had left.

Like a meteor, the demon's body slammed into the floor with a bone-crushing thud, the sound echoing through the chamber. The impact cracked the stone beneath them, sending dust and debris flying as light poured in from above, illuminating the chaos. The demon's body lay still, his sword lodged deep in its skull, the once-pristine blade of Astora now broken, shattered from the final blow.

He stood there, panting, barely able to keep himself upright. But he had done it. He had won. He had slain the demon.

The adrenaline left him all at once, and he collapsed backward onto the demon's corpse. His body was numb, every nerve frayed and useless. His vision blurred as he lay there, staring at the hole in the ceiling. It was over.

But then Naruto saw it—the soul of the stray demon. It gathered above him, swirling into a massive ball of light, pure white with a black shard at its core. It was bigger than him, pulsing with energy, more beautiful and terrifying than anything he had ever seen.

He smiled, weakly raising his hand toward it.

I did it.

A single tear slipped down his cheek as the soul absorbed into him, filling him with a warmth that reminded him of Oscar. Of everything he had taught him. And as the last bit of that soul merged with his, Naruto let his hand fall to his side, his body finally giving in to the exhaustion.

We did it, Sensei. We did it.

Author Note:

Holy shit, this was an incredible chapter to write!

I know many of you are probably feeling sad about Oscar's death (RIP). If you've played Dark Souls, you'll know that Oscar is already near death when meeting the protagonist in the game. The same thing happens here, but with a deeper connection, weight, and legacy. This was planned from the very beginning—Oscar's death creates ripple effects that will profoundly shape both Naruto's character and the world itself in ways you may not even see coming yet.

So, let me know what you thought of Oscar as a character. Despite his short appearance, I tried to give him depth, history, and a sense of culture—elements that felt a bit lacking in the game itself. I'd love to hear your thoughts!

Now, onto the Asylum Demon… In the games, the Asylum Demon and the Stray Demon are two separate bosses. So, why did I merge them into one creature with two distinct phases? Simple: it adds layers to the Asylum Demon's character, builds some intriguing lore, and makes the encounter more memorable.

What did you think of this change?

How did the fight come across to you?

And what did you think of the intensity and brutality in it all?

Thank you for your support and for enjoying my work.
