Uzumaki Kushina had lived in Uzumaki Mito's home when she was a child.
After all, Mito, the wife of the First Hokage, was from the same clan as her.
Loved and cherished by Uzumaki Mito, Kushina had grown up under her watchful eye.
One day, Tsunade decided to visit her grandmother, Uzumaki Mito.
And that was when she saw her—this adorable little girl with striking red hair and a fiery spirit.
After Kushina graduated from the Academy, she eventually became Tsunade's disciple.
But over time, their relationship evolved.
Tsunade no longer saw her as just a student.
Instead, she treated her like a younger sister.
And now, watching her so easily fall into the arms of another man…
Tsunade couldn't shake this strange feeling inside her.
Something felt off.
No, it wasn't about the man himself.
She just needed to be cautious.
"Sister Tsunade, Kurama-sama is very strong," Kushina said confidently, a gentle smile on her lips.
"Don't worry about it."
But Tsunade wasn't listening.
In her opinion, Kushina was hopelessly lost in the sweet haze of love, unable to see things clearly.
Everything about this "Kurama" must seem perfect in her eyes.
But Tsunade wasn't some naive little girl like Kushina.
She had seen the world.
She had experienced too much to just accept things at face value.
How strong this Kurama truly was… she wouldn't believe it until she tested him herself.
"Kushina, don't be fooled by a handsome face," Tsunade warned, crossing her arms.
"As the saying goes, a man's words are nothing but lies.
I have to make sure you're not being taken advantage of."
Since Tsunade was so insistent, Kushina decided to let things unfold naturally.
She was curious to see what exactly Tsunade had in mind.
And maybe, just maybe…
She was looking forward to it a little.
"Check? How do you plan to 'check' him, Sister Tsunade?"
Kurama didn't mind at all.
Whatever Tsunade wanted to do, he'd simply go along with it.
"Hey, kid," Tsunade smirked, cracking her knuckles.
"I'm the God of Gambling in the ninja world.
If you want to take Kushina away from me, how about we make a bet?
If you win, I'll acknowledge you."
Kurama blinked, unimpressed.
Sure enough, Tsunade's idea of "testing" someone wasn't anything new.
What else did she ever rely on besides gambling?
It was almost predictable.
Kurama sighed, rubbing his temple.
"What are we betting on?" he asked lazily. "Arm wrestling?"
Tsunade's expression shifted.
"Hey, kid, how did you know that?!"
She hadn't even spoken her thoughts out loud, yet he guessed it right away.
Was this guy a mind reader?
To her, arm wrestling was the perfect test.
It cost nothing, unlike her usual gambling addiction.
And more importantly, it was a contest of pure physical strength.
She had never lost before.
Kurama shrugged.
"Call it intuition," he said. "Besides, what else would you come up with? I can't imagine you thinking of anything other than using brute force."
Tsunade narrowed her eyes.
"You little punk, who are you calling simple-minded?!"
"Why? Did I hit a nerve?"
"Asshole!"
Tsunade clenched her fists, glaring at him.
Was this how he treated Kushina?
Yet… for some reason, she wasn't really angry.
More than anything, she felt amused.
She wasn't used to being spoken to like this.
And the fact that he called her "pretty" earlier…
Not that she cared.
Absolutely not.
Kushina, meanwhile, was barely holding in her laughter.
This was the first time she had seen Tsunade flustered like this.
It was… refreshing.
"As expected of you, Kurama-sama," Kushina murmured with a grin.
"If I tried to fight Sister Tsunade, I'd be tasting her iron fist of love."
Tsunade wasn't like other female ninjas.
Most wore fishnet armor beneath their clothing, at least partially.
Tsunade, however, didn't bother.
And when she walked, it was like an earthquake followed her.
"Alright then," Tsunade grinned, rolling her shoulders.
"Arm wrestling it is!"
Kurama and Tsunade didn't look particularly excited.
But Kushina…
She looked thrilled.
To her, this was pure entertainment.
On one side, there was Tsunade—her strong, terrifying sister figure.
On the other, there was Kurama—the man she admired.
Who would she support?
Obviously, Kurama.
If he won, Tsunade would have to acknowledge him.
It would settle everything.
And besides…
Kushina didn't believe for a second that Kurama would lose.
Tsunade might have monstrous strength, but Kurama was on a different level.
It wasn't even a contest.
Tsunade was a lake.
Kurama was the vast, endless ocean.
Tsunade was a single star.
Kurama was the entire universe.
There was simply no comparison.
"Hey, you brat," Tsunade muttered, shooting a glare at Kushina.
"Stop standing there grinning like an idiot.
I'm doing this for you, you know."
Kushina smiled, looping her arm around Tsunade's.
"Of course, Sister Tsunade. I support you all the way."
That was what she said.
But in her heart, she was thinking something very different.
"Sister Tsunade… just give up. You have no chance against Kurama-sama."
Still, something else suddenly crossed her mind.
Tsunade always talked about how everyone who gambled against her was a "big fat sheep."
They always lost.
But now, for the first time, Kushina had her doubts.
Maybe… just maybe…
Tsunade herself was the fat sheep this time.
Kurama smirked.
"Kushina, have some confidence," he teased.
"If anyone here's gonna lose, it's her."
And with that, the three of them moved to an open space.
Tsunade and Kurama sat down, placing their elbows on the stone table.
As their hands clasped together, Kurama noted something interesting.
Tsunade's hands were surprisingly soft and smooth.
"Hmm," he mused. "Not bad."
Tsunade's eye twitched.
"Hey, brat, what's with that look?" she snapped.
"Don't underestimate me! I'm Tsunade, one of the Legendary Sannin!"
Kurama's casual attitude irritated her beyond belief.
In Konoha, no one dared to look down on her like this.
Except, apparently, for him.
This guy was dangerous.
Too smooth. Too confident.
No doubt, he had completely ensnared Kushina already.
She had to wake her up from this spell.
Crack—
Tsunade pressed a single finger into the ground.
Deep cracks spread instantly, running for meters.
The ground trembled.
The destruction was instant, effortless.
This was the strength of Tsunade Senju.
"Scared yet, brat?"
Kurama only smirked.
He started clapping, slow and deliberate.
"As expected of Kushina's teacher," he said smoothly.
"Legendary Sannin. Granddaughter of the First Hokage.
So very impressive."
He let out a small, dramatic sigh.
"To be honest… I'm a little scared.
Should we cancel the bet?"
Kushina pressed her hands to her mouth, trying to suppress her laughter.
"Kurama-sama, you're such a damn actor."
Tsunade puffed out her chest proudly.
"Hmph! You think you can back out now? No chance.
This ends here.
Prepare to witness your own defeat!"
Kushina took a deep breath.
"Alright, both sides ready?"
The moment she dropped her hand…
The match began.
And Tsunade grinned.
"Boy, you're going to lose!"l
