Naruto: Seishin – The Bond That Binds

The briefing had been rushed. Too clean. Too coordinated.

Coulson had delivered the instructions with a chilling calm:

Extraction of Dr. Anton Nemenov, former Dynamo program researcher.

Location: Brooklyn Docks, Sector 42-B.

Threat level: "Unknown, but contained."

Team: Romanoff in tactical command. Two S.H.I.E.L.D. agents for support.

Naruto: classified as a "non-aligned asset under monitored presence."

In other words: allowed to tag along… but strictly no interference.

Natasha had felt the trap.

But she accepted.

Not for S.H.I.E.L.D.

For him.

To prove to him that he could still belong in this world.

The warehouses were silent. Too silent.

Natasha led the way, gun raised. Naruto took the rear, senses alert.

He felt something.

Not a direct threat. A lie. A veil.

Human silhouettes danced behind crates. Heartbeats. Too regular.

— "Take cover," he murmured suddenly.

But too late.

The lights cut out.

Then: Explosions. Crossfire. Drones activated. Augmented units inbound.

Heavily enhanced soldiers emerged from the shadows—cybernetic implants, energy shields, semi-biological weaponry. A covert S.H.I.E.L.D. unit: Neuron Division.

And behind them, the uniformed agents turned their weapons on Naruto.

— "Protocol 7 – Eliminate the unstable factor. Fire."

Natasha screamed.

Naruto didn't move.

Bullets tore through the air.

Naruto simply raised his hand.

A condensed chakra barrier formed around him—dense, red, vibrating.

The projectiles melted before they reached him.

Then he stomped the ground.

The concrete cracked beneath him.

A shockwave rippled across the entire warehouse, disorienting the drones.

One cyber-soldier lunged with an energy blade.

Naruto sidestepped, pivoted, and drove his fist into the man's chest.

Boom.

The soldier was launched through two concrete walls.

But Naruto wasn't enraged.

He was calm.

And that was far worse.

Meanwhile, Natasha faced three heavily armed agents.

Double-barrel rifles. Paralysis grenades. Nanite-loaded syringes.

She dropped one with a clean throat shot.

Dodged a grenade. Neutralized the second in hand-to-hand, breaking his arm in a brutal lock.

But the third... the third wasn't there to capture.

He fired point-blank.

She felt the impact tear through her vest.

A modified tungsten-core bullet.

She fell back, breath knocked out of her.

And Naruto screamed her name.

NATASHA

Naruto ran without thinking.

Drones closed in.

He leapt.

Three meters. Five. Ten.

A flurry of lightning-fast hand seals.

Shinra Tensei.

The machines detonated in a wave of gravity.

He landed on his knees beside her.

She was bleeding.

Heavily.

Too much.

He placed his hands over her wounds.

The glowing marks on his body widened.

And on his left palm, a symbol formed:

☯ – Seal of Cellular Preservation – ☯

Naruto closed his eyes.

He channeled everything.

Not just chakra.

His will.

His fear.

His love.

A soft light surrounded Natasha.

Her heartbeat steadied.

Her wounds began to close—slowly.

Not magically.

Biologically.

As if life itself remembered what it was meant to be.

And with a single breath…

She opened her eyes.

— "I'm here," he said.

She smiled.

Then fell into sleep.

She woke three hours later.

Lying in a sterile bed, biometric monitors strapped to her arm.

Naruto was there.

Sitting beside her.

Eyes sunken. Bare chest still marked by chakra burns.

But he smiled.

And she whispered:

— "You saved me again."

He tilted his head.

— "You kept me from becoming what they want me to be."

Night fell.

They were alone.

She invited him beneath the sheets, wordlessly.

He joined her, gently.

Not to possess.

But to heal.

Their hands found each other.

So did their bodies.

They made love without haste.

Without domination.

In slowness, in respect, in naked truth.

When sleep came, Natasha murmured:

— "I never belonged to anyone."

Naruto squeezed her hand.

— "And I never wanted to own anyone. Just to be seen."

She rested her head against his chest.

And fell asleep in that silence.
