Monaco Grand Prix — October 15, 3:42 PM
Temperature: 28°C — Humidity: 46%

The engines roared. The crowd erupted. Flashes, cheers, champagne sprayed in the VIP lounges. Everything pulsed.
But Naruto, seated in the secured Stark Industries tribune, didn't smile.
He couldn't understand why Tony had decided to drive the car himself.
Or why his vital signs had suddenly weakened just before the race began.

[ System Alert: Anomaly Detected ]
> ▓ Primary chakra detected: Stark, Anthony
▓ Palladium blood saturation: 12.3% [CRITICAL]
▓ Cellular anomaly: accelerated hepatic deterioration
▓ 🔒 File locked by subject. Password required.
Naruto clenched his fists.
"You're hiding this from me..."
Pepper's voice chimed in his earpiece, calm but tight with tension.
"Naruto, we got a message from Happy. Someone breached the rear security line. Unknown male. No clearance."
Naruto stood up instantly.
"It's happening."
---
On the track, a figure stepped into the middle of the circuit — armed with two electro-plasmic whips, crackling with rage.
Ivan Vanko.
Cars crashed. One exploded. Tony leapt from his half-burning vehicle.
Panic swept the stands.
Naruto vanished.
---
Seal Clones (Fuin Bunshin)
Before reaching Tony, Naruto created two invisible clones — a mix of chakra and camouflaged seals.
They darted between guards, placing three fuinjutsu tags on support pylons.
> ▓ Function: undetectable surveillance
▓ Purpose: trace opponent's energy flow
▓ Status: ACTIVE
Ivan advanced.
Tony, without his full armor, clumsily blocked the whip strikes with a partial energy vest.
Each hit buckled his knees. He was drenched in sweat. The ARC reactor in his chest flickered erratically.
Naruto landed between them in a burst of crimson lightning.
"Enough."

: Hostile Intent Detection (Shikaku Sutairu)
A mental alert triggered in Naruto's mind.
Ivan Vanko radiated pure, cold, impersonal murderous intent.
> ▓ Targeted Hostility: ideological
▓ Detected Motive: vengeance — Stark legacy
▓ Dominant Emotion: ancestral disgust
Naruto narrowed his eyes.
"You don't want to kill Tony. You want to kill what he represents."
Ivan growled.
"Fathers lie. Sons pay."
He whipped again, but Naruto moved before the strike even began.
---
Residual Fusion (Yūkō na Gōryū)
Naruto extended a hand. A quick seal formed in the air, linking symbolically to Tony's ARC reactor.
"Hold on. Borrow my reflexes."
Tony felt his arm move before he gave the command.
A reflex dodge. Controlled breathing. A balance he hadn't felt in weeks.
"What did you do?!" he yelled.
"Sharing my nerves. Not my chakra."
"You want me to cry or survive?"
Naruto grinned amid the chaos.
"Both."
---
✧ Function No. 18: Body Exchange (Karada no Kōkan)
But Tony collapsed.
A dull vibration rattled through his chest.
Naruto knew instantly — the poisoning was advancing.
He focused. A seal activated on his palm.
"JARVIS. Instant hepatic analysis."
> ▓ Partial failure detected.
"Partial liver transfer. 5% functional tissue. Chakra-infused. Lock the transfer for 72 hours, no more."
> ▓ Accepted. Transfer initiated.
Naruto placed his hand on Tony.
The world hushed.
A golden pulse passed between them.
Tony gasped, breath returning.
"Did you just...?!"
"You'll make it."
"You're insane."
"And you're alive."
---
Happy finally arrived with the armor suitcase.
Pepper was beside him, face pale.
"Tony!" she screamed.
Naruto intercepted. Ivan was unconscious. The clones had trapped him with a static seal.
"He's stable. But not for long."
"What did he do to you?" Pepper asked, noticing Naruto bleeding slightly at the side.
"Nothing I didn't choose to give."

[ System Standby ]
> ▓ Partial liver transfer: SUCCESSFUL
▓ Clones: deactivated
▓ Intent analysis: archived
▓ Fusion link: Tony Stark – TEMPORARY status
▓ Naruto vital overload: 4% – regeneration expected within 48h
Kurama murmured inside Naruto's mind:
> "You just saved his life. And he doesn't even realize this was only a taste of what's coming."
Naruto, exhausted, replied:
"He will. But I want him to earn it."
