Compared to its initial form, the first stage of Susanoo was far more massive, standing approximately ten meters tall.
The giant ribcage rapidly expanded, transforming into a skeletal upper body.
Just this upper torso alone was enough to reach such an astonishing height, and the Susanoo's arms were now several times larger than before as well.
At this moment, both Uchiha Byakuya and Yoshimura Eto were completely encased within the Susanoo.
Due to the influence of RC cells, Byakuya's Susanoo had materialized into a tangible form.
However, while Byakuya and Eto could see the outside world from within, Kaiko and the black-clad operatives could not see anything inside.
"Is this… a kakuja transformation?"
Eto was stunned as she realized she was inside the body of a massive giant.
She had never seen a kakuja this enormous before.
What shocked her even more was that Byakuya was still standing in a normal posture on the ground, while she was clinging onto him; his kakuja transformation hadn't affected her at all.
The so-called materialization was, in truth, merely a visual alteration.
In essence, Susanoo was still the same as ability as before.
Originally, a Susanoo was a manifestation of chakra in a tangible form, appearing semi-transparent in its usual state.
But despite this transparency, it still possessed immense destructive power and near-impenetrable defense.
Thus, as long as Byakuya willed it, Eto could move freely within Susanoo or even exit it at will.
Conversely, enemies had no such privilege.
"A Kakuja? How is this even possible?!"
Kaiko stared up in disbelief at the massive blue ethereal giant before him.
Even though it was only an upper torso, its sheer size was utterly mind-boggling.
But what baffled him the most was; why could Uchiha Byakuya undergo kakuja transformation to begin with?!
A moment ago, Kaiko had noticed that Byakuya's eyes were blood-red; had this kid secretly implanted himself a kakuhou?!
And if so, how had he done it without the Washuu Clan noticing?!
On top of that, his kakuja's form had already surpassed even the One-Eyed Owl!
The other black-clad operatives were equally dumbfounded.
Their reaction was no better than Kaiko's.
The latter was simply the first to regain his composure.
He immediately fired another shot from his ukaku quinque at the Susanoo.
"BOOM!!"
The RC Condensed Shell exploded directly upon impact.
Seeing that his attack had landed successfully, Kaiko smirked in triumph.
"Hah! I thought you'd be stronger than this. Even though your body is huge, you're nothing special after all."
He sneered with contempt.
Clearly, he had great confidence in his SSS-rated quinque.
In his mind, Byakuya must have taken serious damage from that blast.
And if this so-called kakuja transformation was this slow, then wasn't it just a giant punching bag?
However, the next moment made him freeze in disbelief.
As the smoke and dust settled, the Susanoo stood completely unharmed.
"What?!"
Kaiko's eyes widened in shock.
The other black-clad operatives were equally dumbstruck.
Even Kaiko's SSS-rated quinque… had failed to leave so much as a scratch.
A wave of panic surged through them.
If not even an SSS-rated quinque could pierce this defense… then what were they supposed to do?!
In the world of Tokyo Ghoul, the Susanoo was an ultimate offense and defense in one.
This was nothing short of a dimensional power gap.
This was truly the power of a god!
"Amazing... Just like that, you're crushing them completely!"
At this moment, Eto was stunned by the sheer power of Susanoo.
Now, she fully understood where Byakuya's confidence had come from.
"Don't get ahead of yourself. This isn't everything yet."
Byakuya said calmly.
Right now, Susanoo lacked a proper weapon, which meant he couldn't take out so many enemies all at once.
But with Susanoo's second stage, this problem would be solved.
As soon as Byakuya willed it, Susanoo underwent another dramatic transformation.
This time, its size nearly doubled.
From its skeletal structure, it grew flesh and armor, and most importantly; a weapon materialized in the Susanoo's hand.
That weapon was an enlarged version of the S+ rated koukaku quinque, "STK", now transformed into a massive sword.
This was Byakuya's conscious decision; he had designated the S+ rated "STK" and the SSS-rated "Owl" as Susanoo's exclusive weapons.
However, using "Owl" would require far more energy, so he opted against it for now.
Eto looked up at the ever-growing form of Byakuya's kakuja, astonished.
"I'm really starting to wonder what your body is even made of..."
After all, as a half-human, Byakuya could eat normal food, meaning his RC cell levels should have been quite low.
And on top of that; he didn't even have a kakuhou.
No matter how she thought about it, there was no way he should be capable of a kakuja this massive.
At this point, he had to be at least twenty meters tall.
Could mutated half-humans really be this absurdly overpowered?!
Meanwhile, Kaiko and the black-clad operatives were completely dumbstruck.
Their faces were filled with utter disbelief as they stared at the towering blue giant before them; a kakuja this massive, and it even wielded a quinque-like weapon?!
Byakuya had no intention of giving them a chance to recover from their shock.
In Susanoo's other hand, a new weapon materialized:
Yasaka Magatama.
A massive, Sharingan-shaped magatama, colored the same ethereal blue as the Susanoo itself.
Its destructive power was immense, and it was a signature ability unique to the second stage of the Susanoo and beyond.
As for how to use it, it was as simple as throwing it.
Even though Kaiko and the black-clad operatives had no idea what this thing was, they could instinctively sense the overwhelming danger it posed.
But it was already too late.
With a simple flick of Byakuya's wrist, his Susanoo hurled the Yasaka Magatama at Kaiko's group, the sheer speed of the attack was utterly absurd.
Kaiko and the black-clad operatives had no time to react.
"BOOM!!!"
The terrifying explosion of the Yasaka Magatama instantly engulfed Kaiko and his entire squad; not a single one survived.
They were completely obliterated, not even a trace of their bodies remained.
[Ding! Host has defeated the Associate Special-Class Investigator "Kaiko"!]
[Reward: 300 Attribute Points.]
[Ding! Host has defeated a Special-Class Half-Human!]
[Reward: 100 Attribute Points.]
[...]
In an instant, Byakuya gained a massive number of Attribute Points.
At that moment, Arima Kishou and Yoshimura Kuzen finally arrived at the battlefield.
"Looks like the fight is already over..."
Arima raised his head, gazing up at the colossal giant before him.
It was hard to believe that this "kakuja" actually belonged to Byakuya.
But aside from Byakuya, who else could it be?
"What… is this...?"
Still in his own kakuja form, Yoshimura Kuzen was shocked beyond words as he stared up at the gigantic Susanoo before him.
He never thought he'd one day find himself looking so small in front of someone else's kakuja...
