Ever since Tsunade began teaching Kirito in earnest, the sound of combat could be heard every morning from the independent courtyard of the hot spring inn.
For the sake of convenience and peace and quiet Tsunade had simply bought the entire small yard outright.
Rich really was rich.
During the day, she trained Kirito in physical conditioning and ninjutsu.
At night, Tsunade inevitably gave in to temptation and headed off to the casino… where she continued losing spectacularly.
Meanwhile, Kirito stayed behind, quietly reading medical texts.
If there was anything he didn't understand, Tsunade would explain it the next day.
Over time, their relationship steadily deepened—strictly as master and disciple, of course.
And just like that…
Seven years passed.
In those seven years, Kirito completely mastered Tsunade's monstrous strength technique, Creation Rebirth, and the Hundred Healings Seal.
His medical ninjutsu had grown increasingly refined, to the point that even Shizune was often surprised.
Daily high-intensity training also caused his Blackbeard template and physique to steadily unlock.
Only Armament Haki had remained sealed for most of that time—the conditions clearly hadn't been met yet.
At this moment, Kirito sat quietly in his room, reading books related to the soul.
The Senju clan had once been a dominant family during the Warring States Era, and Senju Tobirama's obsession with ninjutsu research had left behind an unmatched collection of texts.
It was no exaggeration to call it the greatest library in the shinobi world.
Thanks to that, Kirito learned far more about the hidden mechanics of this world than most ever would.
Seven years later...
Namikaze Kirito was now ten years old.
Thanks to his pirate-world physique and extreme nutritional absorption, his body already resembled that of a fifteen- or sixteen-year-old.
He stood nearly as tall as Tsunade.
His long red hair was tied into a loose ponytail with a simple straw rope, a few unruly strands falling across his forehead.
Between his brows sat a diamond-shaped seal, identical to Tsunade's—except his was black.
Years spent beside Tsunade had subtly shaped his style as well.
A white shirt worn half-open revealed a well-defined torso, black trousers hugged his frame, and a knee-length black coat hung casually from his shoulders. (PS: Shanks with Blackbeard's powers… yeah, I see the drip.)
It resembled a cloak more than clothing.
Very… pirate-like.
With Namikaze Minato's looks and Kushina's features combined, plus his relaxed attire—
His handsomeness had taken on a wild, dangerous edge.
"Open the panel."
Host: Namikaze Kirito
Peak Blackbeard (Fully Enhanced) Template Unlock: 21%
Observation Haki: Unlocked
Armament Haki: Unlocked
Conqueror's Haki: Unlocked
Tremor Fruit: Unlocked
Dark Fruit: Unlocked
Physical Fitness: 20
After seven years, the changes were dramatic.
The template unlock rate had reached 21%.
Both the Dark Fruit and Tremor Fruit had been deeply developed.
His physique—now ten times stronger than before—had improved the most.
With pure physical combat alone, ordinary jōnin would struggle against him.
This didn't even account for monsters like Might Guy.
His chakra reserves were even more frightening.
As his body strengthened, his chakra grew explosively—by an entire order of magnitude.
At just ten years old, his total chakra capacity had already reached Kage-level.
And that was with most of it being stored inside the Hundred Healings Seal.
Had he released it all…
It would have been even more absurd.
When Tsunade tested his chakra nature years ago, the result had surprised her.
Like Sarutobi Hiruzen, Kirito possessed all five elemental affinities.
With such vast chakra, he could overwhelm enemies through sheer coverage alone.
Of course, having Kage-level chakra didn't mean he could casually defeat a Kage.
Every shinobi who reached that level had terrifying trump cards of their own.
But against most Kage-class opponents, Kirito could already fight evenly.
And if either Devil Fruit ability came into play…
A single mistake could decide the battle.
If this were the Kirito of today...
That night…
That most regretful night—
He could have stopped everything.
But time could not be reversed.
Now, he could only search for another path to revive Minato and Kushina.
These days, Tsunade had very little left to teach him.
So she often went gambling even during the day.
In the early years, she never left his side—partly due to Jiraiya's warnings.
Now?
Only Tsunade and Shizune truly understood how terrifying Kirito had become.
That was also why Danzo's Root had never dared make a move.
Jiraiya could be pressured with village politics.
Tsunade could not.
If Root spies were discovered, Tsunade would march back to Konoha and flatten their headquarters.
Danzo wouldn't even dare complain.
The Senju Princess's influence wasn't a myth.
The Senju hadn't vanished—they'd simply shed their surname and merged into Konoha's population.
On top of that, Tsunade had saved countless comrades during the wars.
Her prestige utterly eclipsed Danzo's shadows.
After reading for so long, even Kirito felt mental fatigue.
He stood, rubbing his temples.
"Seven years… passed just like that."
Looking at the courtyard that had become his training ground, a faint smile surfaced.
All these years, Tsunade and Shizune had cared for him like family.
And at some point, he had come to see them the same way.
His outward coldness gradually faded.
At times, he even resembled his father—gentle, calm.
Lately, though…
There was a new problem.
Tsunade was getting far too close.
She'd stopped avoiding him entirely.
More than once, after drinking too much, she'd stumbled into the wrong room—
Using Kirito as a pillow.
Snow-white thighs draped over him.
Arms wrapped tight.
He could break free.
But he didn't.
First, because he was afraid of hurting her.
Second…
He didn't know why.
So he let her sleep.
That used to be manageable.
His mind might've been adult, but his body hadn't fully matured.
Recently, however—
That had changed.
Every morning now was torture.
If this continued, Kirito genuinely didn't know what would happen.
He locked the door every night—
Tsunade just kicked it open.
As for Shizune?
Her gentle nature was no match.
All she could do was apologize afterward.
"…What do I do?"
Kirito sighed, rubbing his forehead.
