Naruto:AFK SYSTEM (COPY ABILITY )

1. The Moment of Opportunity

Rin stood in the empty training ground, his eyes locked onto Sasuke.

"This is it."

He had already copied Naruto's Uzumaki bloodline and Asura's chakra—but his body couldn't handle it. His chakra surged wildly, unstable, as if something vital was missing.

That something was Indra's chakra.

If he could take that from Sasuke, he'd finally have both halves of the legendary power that led to the creation of the Rinnegan.

But this wasn't going to be easy.

Sasuke narrowed his eyes. "You've been acting weird lately, Rin."

Rin smirked. "Maybe I just want to test myself."

Sasuke scoffed. "Fine. But don't expect me to hold back."

"Perfect."

2. The Duel Begins

The wind rustled through the trees as both boys took their stances.

Then—they moved.

CLASH!

Their kunai met in a flash of sparks, eyes burning with determination.

Sasuke's movements were sharp and precise—his training with the Sharingan had made him far more dangerous than before. But Rin had something he didn't.

His own Sharingan activated, spinning rapidly as he mirrored Sasuke's attacks.

"The advantage of copying techniques isn't just learning them—"

Rin dodged a kick, countering with a sharp elbow.

"—It's predicting what comes next."

Sasuke barely blocked in time.

His eyes widened. "He's keeping up with me?!"

He jumped back, forming hand seals.

"Fire Style: Phoenix Flower Jutsu!"

Small fireballs shot toward Rin from multiple angles.

Rin smirked. "I knew you'd do that."

His hands blurred—

"Water Style: Water Bullet Jutsu!"

A stream of water erupted from his mouth, extinguishing the flames mid-air.

Sasuke grit his teeth. "He copied that instantly?!"

3. Contact

Rin darted forward, closing the gap. This was his chance.

Sasuke prepared to counter, but—

Rin grabbed his wrist.

[New Bloodline Detected… Scanning...]

Sasuke's eyes widened. "What are you—?!"

A surge of energy erupted from Rin's body. His veins burned, his muscles tensed, and his vision blurred as new power flooded his chakra network.

[Indra Ōtsutsuki's Chakra Copied]

[Asura and Indra Chakra—Fusion Imminent]

"It's working… but—"

A sudden shockwave of energy blasted from his body, throwing Sasuke backward.

Rin clutched his head, pain erupting through his skull.

Something inside him was breaking.

4. The Curse of Balance

His heartbeat roared in his ears as his chakra spiraled out of control.

Kakashi appeared in an instant, his single eye sharply focused on Rin.

"Too much power at once. His chakra network is unstable!"

"Rin!" Kakashi shouted.

But Rin could barely hear him.

Inside his mind—

He saw two figures.

One bathed in blazing golden energy, his eyes filled with warmth and fire. Asura.

The other cloaked in deep violet flames, his gaze cold and calculating. Indra.

Both of them stared at him.

And then—

They attacked.

5. The Battle Within

Inside his consciousness, Rin was trapped between two forces.

Asura's chakra surged forward like an unstoppable current, overwhelming him with raw power.

Indra's chakra coiled like a serpent, precise and deadly, seeking to dominate him completely.

"They're fighting inside me—"

"No—"

"They're trying to claim me."

His body convulsed, his breathing ragged.

If he didn't stop this now—he would be torn apart.

But then, a realization struck him.

"I don't need to choose one over the other."

"I need to bring them together."

Summoning every ounce of willpower, Rin focused inward.

Instead of resisting—he embraced both energies.

He let Asura's warmth flow through his left side—Indra's cold flame through his right.

And slowly—they merged.

6. The New Power

Outside, Rin's chakra stabilized.

The violent aura around him faded, condensing into something refined.

His Sharingan spun wildly, shifting for a moment—

But then, it stopped.

His breath steadied.

He had done it.

Kakashi exhaled in relief. "He… controlled it?"

Sasuke sat up, glaring. "What the hell was that, Rin?"

Rin just smirked.

"I'm finally complete."
