"Ah, another pleasant day!"
In the morning, Kyoya stepped out of his bedroom and stretched lazily.
With his strength having improved once again, Kyoya's mindset had also undergone a significant shift.
If yesterday, Kyoya still somewhat thought of this as 'Yamamoto's Seireitei', now, he had already begun transitioning to the mindset of 'my Seireitei'.
Well, of course, Kyoya hadn't quite reached the stage of 'I can do anything' yet, but there was already a hint of that attitude.
In the past, Kyoya had considered defecting from the Seireitei to unlock other career paths in order to gain greater strength before the Thousand-Year Blood War.
But now, Kyoya had already obtained the Steel Balloon Physique.
Big Mom, who never trained and still recklessly courted death, managed to become one of the Four Emperors.
If Kyoya trained seriously for a hundred years, with his innate talent from this constitution, he wouldn't even need Yhwach… he could storm the Soul King Palace himself and free the Soul King from his suffering!
...Well, that was just a thought.
Even if Kyoya had the strength to kill the Soul King by then, he would still need to wait for Yhwach to initiate the final act of the Soul King's demise.
Kyoya wanted to transcend the both One Piece World and Bleach World, becoming a true 'God', but he had no intention of destroying this world.
If the Soul King died without a replacement to act as the 'linchpin' maintaining the balance of the three worlds, all three worlds would collapse into ruin.
As for last night's incident with the Kasumioji Clan, Kyoya didn't bother paying it any further attention.
After all, he had already killed the mastermind behind it all. If the Central 46 wanted to hold him accountable, Kyoya wouldn't mind sending them off to reunite with their accomplices.
However, since Yamamoto hadn't summoned him yet, Kyoya figured the matter was already settled.
'It seemed the nobles weren't foolish enough to think they could manipulate a young, hot-blooded captain.'
"Alright, time to train!"
After relaxing for a bit, Kyoya lowered his arms, his smile fading as he headed toward the 11th Division's training grounds.
Since he had already decided to reach a level where he could crush Yhwach a hundred years later, Kyoya naturally had to train diligently during this century.
Upon arriving at the training grounds, Kyoya nodded at the other members who were already training before beginning his own regimen.
The [Steel Balloon] was one of the top-tier physiques, and to fully unlock its potential, the Marine's Rokushiki were undoubtedly the most suitable.
Thus, Kyoya's figure began flickering across the training grounds.
Soru, Geppo, Rankyaku, Shigan, Kami-e, Tekkai...
Boom!
Boom!
Boom!
The Shinigami training in the 11th Division's grounds all stopped what they were doing, staring dumbfounded at Kyoya's figure.
Every punch and kick unleashed terrifying shockwaves and sonic booms, forcing them to retreat repeatedly to avoid getting caught in the aftermath of their Captain's training.
"Captain Kyoya is insane!"
"Yeah, it's not just his Zanjutsu… his Hakuda is also on another level!"
"Even Captain Yoruichi of the 2nd Division probably can't match Captain Kyoya in Hakuda, right?"
Yoruichi was one of the few Captains in the Gotei 13 who didn't rely on her Zanpakuto, having earned her position purely through her mastery of Hakuda and Hoho.
But right now, the impression Kyoya gave was that no matter who stood before him, he could crush them with his bare fists.
"Tch, if I had even a tenth of Captain Kyoya's strength, I could strut around the Seireitei like I owned the place."
"Heh, you're dreaming. I'd be happy with just one percent..."
Seeing their captain training so fiercely, the members of the 11th Division exchanged glances before throwing themselves back into their own training.
However, they all wisely kept their distance from Kyoya.
There was no helping it… those sonic booms and shockwaves were downright terrifying.
"...Sigh."
"The training results are too lackluster."
After finishing a round of training, Kyoya closed his eyes and assessed his progress.
Aside from a slight improvement in body control, he didn't feel any significant growth.
At his current level, unless he received another achievement reward, regular training wouldn't provide any noticeable boosts.
He could only rely on time, accumulating strength drop by drop like water forming an ocean.
'What a shame. If Kira Izuru were already grown up, his Zanpakuto's ability would be perfect for assisting my training.'
'But right now...'
Thinking of this, Kyoya shook his head.
Kira Izuru was part of the same generation as Hinamori Momo, Kuchiki Rukia, and Abarai Renji.
Barring any unexpected developments, he wouldn't even enter the Shin'o Academy for several more decades.
Kira's Zanpakuto, Wabisuke, had the ability to manipulate gravity.
Anything struck by Wabisuke would have its weight doubled.
Each subsequent strike would double the weight again.
What's more, Wabisuke's weight doubling isn't based on the object's original weight… it increases exponentially.
For example, if a piece of clothing weighs 0.5 kilograms, after one strike, it becomes 1 kilogram. After two strikes, 2 kilograms. After three strikes, 4 kilograms…
By the tenth strike, the object's weight would skyrocket to over a thousand times its original mass.
Of course, for non-Captain-level Shinigami, their Zanpakuto's abilities would be weakened when used against Captains due to the difference in Reiatsu.
But with an ability like this, even if it's weakened, a few dozen slashes would still be enough to crush even a Captain to the ground, forcing them to kneel and let Kira finish them off effortlessly.
However, what Kyoya valued wasn't Wabisuke's combat potential… it was its training utility.
'If Kira Izuru were to slash me a few dozen, or even a few hundred times, the sheer weight would make training feel incredibly exhilarating, wouldn't it?'
'Tch, I must be losing my mind.'
Kyoya suddenly smacked his own forehead as he thought about Kira Izuru's Zanpakuto ability.
'The Seireitei has the Research and Development Institute, doesn't it?'
'Surely, the researchers of the 12th Division could easily invent a gravity training device, right?'
'No time to waste.'
Kyoya immediately stopped training and headed straight for the 12th Division.
'Sharpening the axe won't delay the cutting of firewood.'
Once the gravity device was complete, his training efficiency would increase tenfold… no, a hundredfold.
A few days of missed training now would mean nothing compared to the gains later.
…
"Captain Kyoya!"
In the 12th Division, Kyoya did not encounter any difficulties.
The guards at the 12th Division didn't hinder him at all.
In fact, upon seeing Kyoya, one of them even volunteered to escort him inside.
Not only was Kyoya wearing a Captain's Haori, but everyone still remembered how, five years ago during the exchange matches, he had kicked Shinji flying across the arena.
While they believed their own Captain, Hikifune Kirio, was unbeatable, but it was still better not to provoke Kyoya if they could avoid it.
…
Kyoya hadn't suppressed his Reiatsu, so the moment he entered the 12th Division's territory, Kirio had already sensed his arrival.
"Captain Kyoya, this is your first time visiting our division, isn't it?"
"Captain Hikifune, I came to ask if the 12th Division could help me create something."
In response to Kirio's politeness, Kyoya cut straight to the point, skipping the pleasantries.
"Create something for you?"
Kirio crossed her arms, studying Kyoya carefully… and the longer she looked, the more shocked she became.
After completing her research on [Gikon], Kirio had applied the technology to herself.
It can be said that at present, her Reiryoku has already ranked among the top.
Kyoya, on the surface, only displayed the standard 3rd-class Reiryoku of an average Captain.
However, in Kirio's perception, Kyoya's Reiatsu felt as vast and unfathomable as the cosmos itself.
That was not something a 3rd-class Reiryoku wielder should possess.
What shocked Kirio even more was, a Shinigami's Reiatsu, when sensed by Reikaku, flickers like a flame. The better their control, the steadier the flame.
After all, every movement a Shinigami makes causes slight fluctuations in their Reiatsu.
So in theory, if someone could maintain perfect Reiatsu stability even while moving or fighting, their control would be at the absolute limit.
Even the Quincy, who manipulate Reishi with precision, would still have fluctuations in their Reiatsu.
But Kirio couldn't detect any significant instability in Kyoya's Reiatsu.
No… rather, the fluctuations in Kyoya's Reiatsu perfectly synchronized with his movements.
If one observed Kyoya's Reiatsu in relation to his actions, it created an eerie sense of 'harmony'.
Kirio couldn't achieve this level.
Not even Captain-Commander Yamamoto could.
In fact, among all thirteen Captains of the Gotei 13, Kirio believed that only Unohana possessed such monstrous Reiatsu Control.
Yet now… she was sensing this same level of mastery in Kyoya, so how could she not be stunned?
Unohana was from the same era as Yamamoto. Even if she was slightly younger, the gap was at most 500 to 1,000 years.
In other words, Unohana's current mastery was the result of nearly two millennia of relentless training.
And the reason she reached such heights was due to her unique past.
A thousand years ago, Unohana was known as the [Greatest Criminal] of the Soul Society. Even after becoming a Captain, she would roam the Rukongai, seeking out strong opponents to slaughter.
It was only after her defeat by Zaraki that she turned to Kaido, leading to her current status.
But Kyoya had only been a Shinigami for less than ten years…
At this time, Kirio had a new understanding of the word 'genius'.
"So… what is it you want us to make?"
