Kakashi Masters All Elements, Rewrites the Ninja World for Rin!

Having made up his mind, Kakashi no longer hesitated.

Just as he was about to step out and explain what had just happened, two familiar figures suddenly emerged from the woods.

It was none other than Biwa Jūzō and Raimi Raiga!

And behind them? A swarm of over two hundred Mist Shinobi pursuing the remaining Konoha ninja.

Biwa Jūzō quickly scanned the battlefield. When he realized the silver-haired boy who had once left a deep impression on him was lying seemingly lifeless, a chuckle escaped his lips.

The terrifying man in green had vanished, and the kid who managed to kill one of them even while surrounded by the Seven Ninja Swordsmen was now presumed dead.

All that remained was to retrieve the girl their master desired. Simple enough.

As for the little brat playing with wood on the other side? Sure, he looked competent—but with their numbers and the combined strength of himself and Raiga, this should be a cakewalk.

Capture the bloodline girl, and chalk up another victory for Kirigakure.

Grinning smugly, Jūzō stepped forward.

"Little girl, just come with us."

"As for the body, feel free to keep it if you're the sentimental type."

He paused, shaking his head with mock regret.

"A shame, though. I wanted to kill him myself... get revenge for Tongarashi Yebai."

Behind him, the Mist Shinobi murmured with admiration.

Lord Jūzō, proud member of the Seven Ninja Swordsmen of the Mist—what a legend.

Raiga rolled his eyes at the theatrics.

You? Kill him? Buddy, you were the first to bolt last time.

Still, he held his tongue. Jūzō was clearly grandstanding to boost morale and salvage some dignity for the Seven Ninja Swordsmen after their previous failures.

GulpGulp

The girl hugging the silver-haired boy—Rin—finally stirred.

Slowly, she raised her head. Her eyes, once gentle, were now filled with raw, blazing hatred.

Then came the sound. A gurgling, surging chakra rising from deep within her.

Translucent red Tailed Beast Chakra erupted from her body—first forming a cloak, then twisting and expanding into a monstrous form cloaked in dark red chakra.

Half-Tailed Beast Transformation—Three Tails!

"ROAR!!!"

The massive form raised its head, chakra swirling violently in front of its maw.

A basketball-sized Tailed Beast Bomb began to form.

Whoosh!

"Everyone, scatter!"

Jūzō's eyes widened as he shouted to the troops, raising his giant blade in a desperate attempt to knock the bomb off course.

Boom!

The explosion shook the entire forest, blasting Jūzō backward.

Shrapnel from his shattered blade pierced his own abdomen.

It was clear—Biwa Jūzō wouldn't survive this.

"ROAR!!!"

Rin, lost in rage and grief, wasn't done.

Another Tailed Beast Bomb—this one nearly two meters wide—began to condense in front of her.

She was determined to obliterate every last one of them.

"Oh great, Rin's soul's on vacation."

Kakashi clicked his tongue.

"Typical. I die once and she brings out a whole-ass turtle from hell."

He immediately sent a Shadow Clone to cover Tobi, while his real self teleported behind Rin using Flying Thunder God.

Boom! Boom! Boom!

The massive Tailed Beast Bomb launched again—straight into the horde of Mist ninjas, triggering a storm of devastating force.

Over two hundred shinobi were instantly swallowed by the blast radius.

And Rin? She was too close.

Swish!

In the nick of time, Kakashi grabbed Rin's tail with one hand, pressed his other palm to Shisui's shoulder, and vanished with Flying Thunder God.

"Senior Silver Fox, what happened?!"

Shisui exclaimed.

"No time for a heart-to-heart. Rin's losing her mind!"

"You've got the Mangekyō Sharingan—use it! Tame the Three Tails before she levels the continent!"

"Understood!"

Shisui didn't waste a second. He activated his Mangekyō, focusing directly on the eyes of the raging Three Tails.

A second later, the beast's monstrous pupils swirled into a matching scarlet pattern.

Rin froze, restricted.

Seeing this, Kakashi calmly stepped forward and wrapped his arms around her.

Sizzle—

The intense chakra burned through his flak jacket instantly.

The tailed beast's aura scorched his front, searing his skin and igniting his own chakra network like a live wire.

But Kakashi didn't flinch.

He simply activated the Hyakugō Seal, and pressed his forehead gently against hers.

In an instant, he was pulled into a storm-tossed mental plane—an empty island where Rin sat at its center, hugging her knees, shaking.

"Rin!"

He rushed forward and wrapped her trembling figure in his arms.

"K-Kakashi…?"

She looked up, dazed.

"Yeah, it's me. Alive and moderately singed."

He offered a faint smirk.

"The one who died? Just a Lightning Clone. Super realistic, but sadly still disposable."

Rin blinked.

Disbelief gave way to a flood of tears.

"You jerk! I thought… I thought you were gone!"

"Why would you lie to me like that?!"

"You big dumb liar, I hate you—I hate you—!"

She pounded her fists against his chest.

"I know… I know, Rin. I'm sorry."

He let her hit him, holding her tightly.

Eventually, the blows softened into a gentle palm resting against his chest.

"…Does it hurt?"

She asked softly, eyes still wet.

She knew full well the pain of a destroyed clone would return to the original.

And a body skewered like a porcupine?

Yeah, that would hurt.

"Pain's relative."

Kakashi gave her a crooked grin.

"It's still not as bad as watching you go full Kaiju mode."

"…Idiot."

She sniffled, but a blush crept across her cheeks as her fingers lightly tapped his chest.

In the past, such blunt honesty would've made her shy away, stammering.

But now?

Now they had been through hell together.

He had never confessed outright—but his feelings were no longer a mystery.

So she saw herself, silently, as his.

And her heart had already chosen.

"…Hey, Rin."

Kakashi leaned closer, voice suddenly more serious.

"Be my girlfriend."

She blinked.

"…Huh?"

Then nodded.

Shyly. Slowly.

"…Mm."

"Hah! That's it, no takebacks now. You're locked in. One hundred years—minimum contract."

He grinned and extended his pinky finger.

"Anyone who breaks the deal becomes a puppy."

"Who'd even want to back out, you idiot…"

Rin replied under her breath, cheeks flushed.

She raised her own pinky finger and linked it with his.

"One hundred years. No backing out. Puppy clause included."
