Naruto: I Survived Two Wars Without You, System!

"Mommy wake up～ Mommy wake up～ Mom～"

Yamato and Xiao He knelt beside Tsunade, gently nudging her as they softly called out.

Perhaps it was the innocence of children, or perhaps just the instinct of young ones.

Their voices brimmed with tenderness and affection.

That heart-melting childlike tone startled Tsunade awake from her nightmare, fear gripping her. She shot up into a sitting position, her face twisted in terror.

"I… must still be dreaming!"

Tsunade stared blankly at Yamato and Xiao He for three seconds, then shut her eyes tightly and flopped back down onto the bed with a loud *dong*. The Yin Seal between her eyebrows released waves of chakra fluctuations, testing whether what lay before her was just a genjutsu illusion.

After five seconds, she drew a deep breath.

She had finally figured out exactly who these two children were, and could guess why they were here.

But…

Why did they call her "mom"?

They were victims of the Wood Release experiment. Even if, technically, they shared distant DNA through her grandfather's cells...

This so-called blood relation made absolutely no sense!

Could it simply be Kei Yamanaka pulling another prank?

No, no, no!

Kei definitely had a despicable personality, but his pranks were usually opportunistic—not premeditated nonsense.

No matter how she thought about it, she felt like something sinister was going on here!

Opening her eyes and sitting up straight, Tsunade looked at the confused and uneasy Xiao He and Yamato, barely suppressing the urge to punch Kei Yamanaka into next week.

A warm smile touched her flushed cheeks as she reached out and gently tousled the two children's hair.

Little girl Xiao He had long, light yellow hair just like hers.

When Tsunade touched her head, she instinctively tucked her chin in, then after feeling the warmth of the palm, showed a shy, sweet smile across her flushed little face.

Boy Yamato had gentle features, delicate like a little girl's.

Upon seeing her reach out, he actively leaned his head closer, making it easier and more comfortable for her to pet him.

"Mom～"

Xiao He murmured timidly, her eyes wide with uncertainty.

Tsunade's temple twitched violently.

Unknowingly becoming a parent?!

Kei Yamanaka—you really take the cake!

"Mm, you two stay here quietly for a moment. I'll take you out for some good food later."

Tsunade responded with a tight smile while saying this, lightly patting both children's heads.

After they obediently nodded in agreement,

Still in her pajamas, she shuffled out of her bedroom, her steps stiff and heavy.

"Kushina, say... if someone in the village said Xiao He and Yamato were Tsunade Onee-san's kids, do you think anyone would believe it?"

Kei Yamanaka spoke with a clear undertone of mischief.

"Hehe～ Maybe they would! Especially Xiao He, her hair color is exactly the same as Onee-san Tsunade's!"

Kushina bit back a laugh, playing along with her boyfriend.

"Then tell me, if Tsunade Onee-san becomes Hokage, would people still dare to say such things?"

"Definitely not. Once the Hokage clamps down, who'd dare spread rumors? And if Onee-san Tsunade revealed the truth about those old experiments, Danzo would be in serious trouble."

"Ah, makes sense. I just wonder if Onee-san Tsunade would even accept being Hokage."

Standing in the living room, Kei Yamanaka's voice oozed menace.

"Hokage? Like hell I would!"

Tsunade's eyes flared wide open.

Realizing exactly what Kei intended,

Chakra gathered around her elegant fists as she charged forward barefoot!

"Kushina, watch these two brats for me. I need to have a little talk with Onee-san Tsunade."

As Kei spoke,

He sidestepped sharply, dodging Tsunade's devastating blow. Grabbing onto the fabric at her waist, he vanished from the house using the Flying Thunder God Technique.

BOOM—WHOOSH!

A violent tremor shook the ground before the training cave at Konoha's northwest edge.

"Damn it!"

Tsunade's left hand clamped down hard on Kei's right arm that gripped her waist.

Her feet sent spiderweb cracks rippling through the ground.

While forcefully pulling Kei toward herself, she simultaneously raised her knee, aiming straight for his crotch.

"Are you serious?! (;′д｀)ゞ"

Kei immediately activated his Hydrification Technique, breaking free from Tsunade's grip.

With his [Zero-Frames Start] ability,

His form quickly retreated three feet, narrowly avoiding this knee strike that posed an intense threat to any man.

Sure, the Hydrification Technique could nullify that kind of damage.

But come on—who wants to take a direct hit there hard enough to explode?

BOOM—WHOOSH!

After missing with the upward knee strike, Tsunade suddenly stomped downward with her right leg, creating deep fractures across the ground. Using the counterforce from the earth itself, she surged forward instead of retreating, her palm aimed straight for Kei's most vulnerable spot!

"Come on sis! Really? Every move you make targets there?"

Twisting his torso sideways, Kei countered with a whip-fast kick aimed at Tsunade's right fist.

Pak~

A dull thud erupted as fist met leg, releasing a burst of thick white smoke.

"You're done." A sly smirk tugged at Tsunade's flushed cheeks.

She removed the bright red nail sticker from her left index finger, bit down hard with a crunch, then swallowed it whole.

"Where's the mutual trust among people? You sleep at my home and yet carry poison on your body? You even hid antidote inside fake nails? Who are you guarding against? Didn't we promise to settle everything already?"

Kei's palm radiated with Sage Chakra light.

Smack! Smack!

He smacked himself all over.

Using the ability granted by [Milk of the Grave] integrated within his [Yin-Yang Sage Ascendant] skill listing, he expelled all sorts of medicinal effects from his body.

He had a thousand sarcastic remarks lined up.

Clearly, Tsunade had been plotting this all along, just waiting for an opportunity to fight him!

So underhanded!

"You started this first! Hahaha, stop struggling, it's useless! Don't you feel your limbs weakening? Your body heating up from within? Can you feel your heart racing and breathing quickening? Do you really think the title 'Konoha's Number One Medical Ninja' is just for show? Hahaha!"

Tsunade laughed loudly while holding her waist.

She hadn't perfected any Medical Ninjutsu that could rival Kei's techniques.

But no worries, she had plenty of strength and methods to spare!

If normal jutsu couldn't match that effect?

Then she'd go straight for medicine!

This very formula—painstakingly crafted after three full days of work at Konoha Hospital.

"Potent formula, rapid-acting, colorless, tasteless, and nearly undetectable!"

It wasn't just Konoha—no one in the entire ninja world could have deciphered her formula within three days!

Even if Kei Yamanaka was strong...

Did she actually believe Tsunade could just slap the poison out of her?

"...C'mon, Sis, you're not scared I'll execute you on the spot, are you?"

Kei's breath grew heavier, his eyes roving openly over Tsunade's body.

"Gah..."

Tsunade's laughter died. She glanced around at the remote, desolate interior of the training cave.

Then she took off running toward Konoha!

Damn it!

She hadn't thought this through!

She'd been too consumed by revenge to even check where they were earlier!

"Hahahaha~"

Kei watched Tsunade flee in disarray, laughing until his teeth showed.

Hearing him laugh so heartily, completely unaffected by poison, Tsunade's expression kept shifting.

Seeing that he made no move to chase after her...

Hadn't she figured out she'd been played?

Furious, she spun around and, her face flushed with embarrassment and anger, demanded:

"How are you not affected?! I released the toxin the second we started fighting! Even if you didn't inhale the final smoke, during our fight, as long as you breathed, there was no way you could have avoided it!"

"Would you reveal your secret techniques to someone like Chiyo of Sunagakure?"

"...Fine, name your condition."

"Then accept becoming Hokage!"

"I already said it before! In your dreams! Over my dead body!"

"Tsunade~ That'll hurt Grandpa's feelings, you know..."

Hashirama Senju's spirit materialized, his face darkening, appearing from Kei's shoulder.

"Grandpa, it's because this guy threatened me that I said that!"

Tsunade glared daggers at Kei.

This bastard actually pulled her grandfather out of the Pure Land—again!

"So you *are* willing to become Hokage! Hahahaha~ I knew it! How could my little Tsunade not want to be Hokage? Son-in-law, you're overthinking."

Scratching his head, Hashirama chuckled aloud.

"...!!!"

Tsunade stiffened immediately, instantly realizing her grandfather had conspired with Kei to prank her!

Damn it!

Was he even her grandfather—or just Kei's now?!

"Tsunade, I just saw those two kids earlier. Well, they both seem like decent kids. Though I really hope you and my son-in-law can have more children, but since that hasn't happened yet, why not start by adopting a couple first..."

"Grandfather! What nonsense are you babbling about! He's NOT your son-in-law!"

"Ah…got mixed up, got mixed up! This...this...Son-in-law, let me have a private chat with my little Tsunade?"

Hashirama spoke to Kei.

After separating from him, he motioned to Tsunade and floated toward the pavilion in the middle of the lake inside the training cave.

Tsunade glared at Hashirama's spirit for a full three seconds before grinding her teeth and following him.

"What are you looking at? Keep staring and I'll force you to drink imported gruel."

Kei muttered under his breath.

Feeling that the [Borrowing an Account to Log In] skill's effect was nearing its range limit.

He took a few casual steps toward the lake, picked up a stone from the ground, and began skipping it across the surface of the water.

Over ten minutes later,

a sudden system notification rang out in his mind.

[Beep~ A major character's destiny path has deviated significantly. The world line progression has been significantly altered. Rewards obtained: Keyword Copy Opportunity x1, Keyword Detach Opportunity x1, Keyword Gift Opportunity x1, Skill Reset Opportunity x1.]

[Beep~ The original world line has been repeatedly disrupted multiple times and is teetering on the edge of collapse and reorganization. Complete destruction of the original world line will yield massive rewards.]

"…Teetering on total collapse, massive rewards."

Kei Yamanaka read the two consecutive system notifications and his expression briefly stiffened.

Altering Tsunade's destiny path and causing a major deviation in the world line progression—this was still within his expectations.

After all, he had already intended to help Tsunade seize power,

replace the Third Hokage, negotiate with Iwagakure and Sunagakure, and carry out the village mergers.

That was no minor change!

But for the world line to be teetering on total collapse…

Massive rewards were tempting, sure—but if the original world line fully collapsed and started to reconfigure…
