A Demi-God in the World of Naruto

Rainbow Abyss

Hades POV

As I plunged into the rainbow abyss, I smirked at Hecate's last few remarks. Her feelings for me were amusing, but I am a loyal man—heart bound to my darling Persephone. I recalled her teasing observation about my obliviousness to other women's affections.

"What did Persephone say again? My density for noticing women's feelings can rival a black hole, and I should be more aware of my charm."

Lost in thought, I failed to notice the colors fading until a hole opened beneath me, swallowing me and leaving the abyss behind.

Land of Fire

A small, rainbow‑rimmed hole appeared in the sky above a lush, green forest. A man plummeted through it—until ethereal black wings of darkness unfurled from his back. He drifted to the ground, inhaled deeply, and surveyed his surroundings.

Hades POV

The forest brimmed with vitality; the air was so pure I suspected a minor god or powerful demigod presided here. I stretched, testing body and mind. The local laws did not suppress me; my divinity flowed unhindered, and no energy drained away.

"But where am I—and what sort of world is this?"

I closed my eyes and spread my senses across the land. I saw merchants with wagons and horses, animals in their natural rhythms, and mortals in blue uniforms and green vests leaping through the treetops, currents of unfamiliar energy coursing through them.

"Horses and carriages—low technology. No trace of divinity; they're mortal, and that energy isn't mana. Ninjas, perhaps? But dull green vests in a bright forest? Stealth clearly isn't their forte."

Then I sensed three people north‑east of me—one near death, the other two barely alive—pursued by burly men cloaked in lightning.

"Interesting. I might as well investigate."

A black portal yawned open, and I stepped through.

Unknown Female POV

Dammit, dammit, dammit! How did these Cloud shinobi find us? This mission was supposed to be secret—for both the village and the clan.

"Reika! What do we do? Daigo's bleeding out—I'm barely standing!"

Akari's desperate voice snapped me back. I glanced at Daigo, unconscious on her back, his wounds severe. Two days of pursuit—from the Land of Lightning, through the land of Hot Springs, almost to the Land of Fire—had taken their toll.

"Put Daigo down, lean him against that tree," I ordered. "Give me every explosive tag. Use what chakra you have left—if we're going down, they'll pay."

Akari complied, though her face was ashen. I forced a reassuring smile, then turned to face our pursuers as they spread out.

"Reinforcements," I muttered. The leader—a hulking man wreathed in lightning—consulted a bingo book.

"Reika Uchiha, 'The Blaze Kunoichi,' bounty 160 million ryō—infamous for turning the Second Great War into a battlefield of fire. Charges include war crimes against multiple Hidden Villages: torching supply lines, incinerating medical convoys, and annihilating an entire Kiri platoon with blue flames in a civilian zone. They say her fire burns hotter when vengeance is involved."

I smirked slightly, memories of screams and burning forests flickering behind my eyes.

He continued.

"Akari Uchiha, 'Sword Princess,' bounty 100 million ryō—confirmed kills include five Jonin in a single ambush, twelve Chunin in prolonged combat, and a Lightning Daimyo's elite guard unit. Specializes in wind-chakra infused kenjutsu; known to sever through armor and bones in one fluid motion. They say she moves like a dancer and kills like a guillotine."

Akari raised her blade, trembling but fierce.

"Daigo Uchiha, 'Demon Eye,' bounty 110 million ryō—put entire squads into shared genjutsu, forcing them to slaughter each other or walk into their own traps. Survivors are reportedly catatonic, incapable of speech."

The captain closed the book, smiling cruelly. "Impressive. But the Hidden Cloud has no use for wild dogs. Your Sharingan, however, will serve us well. The kunoichi will entertain the village—before their usefulness runs dry."

The soldiers howled in laughter, shouting about clan restoration programs, and bloodline preservation units. One gestured obscenely, another held up chains.

My stomach churned with loathing.

This wasn't war—it was organized violation. Breeding pits, forced pregnancies, and systematic genetic exploitation. And somewhere back home… someone had set us up. Only Danzo and his cursed Root could've sold us out for political leverage.

I gritted my teeth.

"Stop stalling and fight, coward!"

"Always together," I whispered.

Akari answered, "Our bonds may set the world on fire."

Daigo, coughing blood, activated his Sharingan. "And may the fan spread the flames."

We braced for our last stand—until a calm voice cut through the tension.

"Excuse me, but this ends here."

Hades POV

I stepped into the clearing. All eyes turned toward me—some confused, some alarmed.

"Hmm. Two injured, one dying, and a squad of would‑be slavers. The choice seems clear."

The woman—Reika, if memory served—shouted, "Civilian, run! They'll kill you… or worse!"

The Cloud captain glared, then barked to his men. "No witnesses."

I addressed Reika's group. "If I save you, will you answer some questions and escort me to your village?"

She hesitated, then nodded. I tossed them three vials of mortal‑grade healing elixir.

Turning to the captain, I smiled. "Good news: I won't kill you first—you have information I need."

 Divine induced terror froze him and his men. "Who are you?"

"Many names, but for now—you may call me Death."

His jaw trembled. "And the bad news?"

"I'm not gentle with memory magic."

I placed my hand on his crown. Time stuttered. A ring of pitch‑black shadows erupted from beneath my feet, spreading like ink across the grass. Where the darkness touched, sound died and light dimmed.

The soldiers struggled, but gravity itself betrayed them—dragging them knee‑deep into shadow‑pools. From those pools rose hounds of living night, jaws dripping starlight‑white ichor. Each bite ripped body and chakra, devouring flesh and soul in a single crunch. Their screams were clipped—swallowed before they could fully form, echoing only inside their own skulls until even thought went silent.

The hounds' red eyes glowed like twin moons in each socket, and their shadows stretched further, devouring the light of the sun above. Some of the enemy tried to fight, unleashing lightning-charged attacks, but the shadows consumed even that energy, growing stronger with each pulse.

They tore through armor and jutsu alike, each soldier devoured in a gruesome spectacle of collapsing flesh and fractured spirit, dragged down into an abyssal void that would never let them return.

Within twenty heartbeats, nothing remained but piles of grey ash and the faint smell of ozone—souvenirs of their stolen lightning chakra. The captain, still in my grip, convulsed. Memories poured into me: routes, codes, every vile intention. And among them, a chilling truth—a secret payment from a masked ANBU agent, pale as ash, with the possibility of the agent belong to Root.

When I released him, his eyes were hollow—mind broken by the mirrored torment I let him taste. He toppled like a puppet with cut strings.

Reika POV

I caught the vials—too stunned to sense the stranger, even with my fading chakra. If neither I nor the enemy sensor noticed him, he was no ordinary civilian.

Akari voiced my fear: "Can we trust him?"

"It's survival or certain death," I answered. "I'll take the chance."

We forced the elixir down Daigo's throat. Color returned to his cheeks; his wounds knit.

"This stuff is amazing!" he gasped. "Eighty percent chakra already."

Akari drank. I uncorked mine—then froze.

The clearing had become a midnight landscape under a noon sun. Where men once stood, only swirling motes of grey drifted upward, hissing like snow on a forge. The captain lay twitching, eyes rolled back, mouth locked in a silent, endless scream.

But it was what came before that haunted me.

Shadows, like liquid obsidian, had risen from the ground. They crept like vines at first—then sprang like beasts. Giant dog heads with jaws wider than a man's shoulders, teeth longer than kunai, emerged and bit down on the Cloud shinobi. The first scream never finished—it dissolved into a muffled gurgle. One man tried to escape, only to be yanked backward, head-first, and devoured in a single crunch.

Their bodies didn't bleed; they broke—shattered into ash and dust, their souls torn from their vessels before they could cry to any kami for help.

Even Daigo, hardened by the war and countless genjutsu-induced horrors, couldn't look away. His eyes shimmered with disbelief.

Akari had covered her mouth, tears forming—not from fear, but the overwhelming presence of true, cosmic justice. Of divine retribution made flesh.

I, the so‑called war criminal, who'd turned enemy strongholds into pyres and vaporized retreating medics—I, who had incinerated men alive and left their bones to howl in the wind—I felt small.

Akari, who once beheaded two Jonin in a single sweep of her wind‑blade under a blood moon, who'd cut through a bunker of Lightning shinobi screaming prayers to their god—she clung to her sword as if it were an anchor to her sanity.

Our savior strolled over, dusting ash from his sleeves as though he'd merely tidied a room. "Feeling better?"

I downed the elixir—sweet and potent. "Yes. Thank you. May we know your village?"

He smiled. "None you'd recognize. I'm a traveler from a distant land—Olympia. Arrived here by accident."

Space‑time ninjutsu, we all thought.

"I gleaned local customs from the captain's mind," he added, toeing the broken man. "Useful, if unpleasant."

We exchanged wary glances. Then I squared my shoulders—time for introductions, Reika‑style.

I pointed to Daigo, who was wiping blood from his chin. "That morose pretty‑boy with 'punch‑me' written on his face? That's Daigo. He's got more drama than a tea‑house novella, but his genjutsu will make you question reality."

Daigo rolled his eyes. "Love you too, Reika."

I slapped Akari's shoulder. "And this hummingbird hopped up on chakra is Akari—the whirlwind of sugar and steel. Give her five minutes and a sword, and she'll redecorate any battlefield."

Akari bowed with an embarrassed grin. "Pleasure."

Finally, I flipped my hair. "And me? I'm Reika—the brains, beauty, and blue flames of Konoha. Prettiest girl in the village; trust me, the bingo book agrees."

The stranger chuckled, eyes twinkling with an age beyond mortal reckoning, and extended his hand. "Hades. A pleasure to meet you all."

That handshake marked the beginning of meeting the interesting man in my life .

One Year and a Half Later

Hades POV

The rainbow‑fringed door stabilized in my home. Reika stood beside me, cradling our son. My heart ached at the time we'd lose, but I had prepared safeguards for them.

"The First Hokage chose a beautiful spot," I mused, gazing toward Konoha.

Reika squeezed my hand, sadness in her smile. "I heard he and my ancestor used to play here during the Warring States era."

I hugged her and kissed her forehead. "I'll miss you, my little firecracker."

"And I, you—my dark lord."

I blessed our child again. Kurogami had his mother's hair and complexion, but the abyssal eyes were mine.

Reika's voice quavered. "Stay in touch, or I'll beat you up, god or not."

I laughed softly. "I promise. If possible, I'll find a way back—or bring you to my world."

She sobbed and held me tight. "You'd better. I'll haunt you otherwise."

I pressed two sealed letters into her hand. "Give these to Kuro when he's strong enough. They contain guidance and contingencies."

She tucked them safely away. "He'll know how amazing his father is."

I kissed her once more, then stepped toward the door. "I love you," I whispered, and let the rainbow light swallow me—leaving the shinobi world forever changed.
