Even behind Yamamoto, a Zanpakuto enveloped in lava emerged.
"This is... our Zanpakuto?"
Some Shinigami, disbelieving, drew their own Zanpakuto and called out their release commands.
But unfortunately, no matter how they called, the Zanpakuto in their hands gave no response.
"It's actually true!"
Many of the Shinigami who tried felt disheartened, unable to muster any fighting spirit.
The Zanpakuto could be considered the Shinigami's most trusted existence.
Even if a Shinigami died in battle, they would never think their Zanpakuto would betray them.
But now, the figures appearing behind Koga undoubtedly cast deeper doubt on the nature of Zanpakuto's existence.
Yamamoto's face now also showed a trace of anger.
The Zanpakuto, as the Shinigami's closest partner, shares two sides of the same coin with the Shinigami.
Shinigami gain more powerful power by learning the Zanpakuto's name, communicating with it, and making the Zanpakuto submit to themselves.
But if a Shinigami doubts this power, the Zanpakuto, being the other side of the Shinigami, will naturally no longer respond.
In that case, the Shinigami's overall strength would drop significantly.
Back then, when Koga released his Bankai Ability in front of Yamamoto and Kuchiki Ginrei, the two men at the top of the Seireitei both knew that the existence of Koga's Bankai Ability would shake the very foundation of being a Shinigami.
Therefore, they tacitly stopped mentioning the matter of having Koga become the 6th Division's Captain.
Later, when Koga was taken away by Kyoya, both Ginrei and Yamamoto felt relieved.
On one hand, before Koga committed any crime, their persecution of him was untenable from the start.
On the other hand, Koga was, after all, the Kuchiki Clan's son-in-law and was once considered the next head of the Kuchiki family.
Executing or sealing the future head of the Kuchiki Clan without cause would inevitably cause unrest among the nobility, making the nobles suspect that the Gotei 13 was beginning to raise its sword against them.
The impact was too great.
Letting Koga leave the Seireitei was the best choice from every perspective.
Moreover, with Kyoya watching over Koga, both Yamamoto and Ginrei felt assured.
Although Kyoya later also left the Seireitei, they similarly believed that Kyoya would not allow Koga to use this power against the Seireitei's Gotei 13.
But now, it seemed they had misjudged Kyoya.
"Kyoya, you have angered me!"
Boom!
Torrential Reiatsu erupted from Yamamoto's body. His white beard fluttered under the overflowing Reiatsu, adding to his imposing manner.
"All Things in the Universe, Turn to Ashes-"
"Ryujin Jakka!"
Boom!
With Yamamoto's shout, his Zanpakuto burst into blazing flames.
These flames illuminated the eyes of the Shinigami who had lost their will to fight.
"The Captain-Commander's Zanpakuto can still be released!"
"What's going on?"
"Didn't the Captain-Commander's Zanpakuto, like ours, go over to the other side?"
"How can Captain-Commander still release his Zanpakuto?"
"Are we under an illusion?"
Hearing the conversations of the surrounding Shinigami cannon fodders, a look of understanding flashed in Byakuya's eyes.
Clearly, Yamamoto was using his own method to make the Shinigami re-recognize their own Zanpakuto, to not believe that their Zanpakuto had truly been turned by the enemy.
It was true that there was a figure of Ryujin Jakka behind Koga.
But he, Yamamoto, could still use his Zanpakuto's power even without Ryujin Jakka!
Holding his own Zanpakuto vertically in front of his chest, Byakuya also recited his Zanpakuto's release command.
"Scatter, Senbonzakura!"
Whoosh, whoosh, whoosh-
Instantly, the blade of Byakuya's Zanpakuto transformed into countless tiny cherry blossom-colored blades, dancing around him.
Witnessing this, the light in the eyes of many Shinigami grew stronger again.
Sighing, Rangiku also stroked her Zanpakuto.
"Growl, Haineko!"
For a moment, many Captains tacitly began releasing their Zanpakuto.
"Flowery Winds Become Disturbed, The God Of Flowers Sings, The Heavenly Winds Become Disturbed, The Devil Of Heaven Sneers."
"Katen Kyokotsu!"
"Claw Out, Ashisogi Jizo!"
"Sting all Enemies to Death, Suzumebachi!"
Even the severely injured Komamura at this moment persisted and released his own Zanpakuto-
"Roar, Tenken!"
For a moment, the Captains' Reiatsu formed an invisible shield, protecting all non-Captain level Shinigami behind them as they faced the numerous Zanpakuto.
Unlike the ordinary Shinigami who had regained their composure, the Gotei 13's Captains, though their faces showed no expression, were far more shocked in their hearts than the ordinary Shinigami.
It was true, they had released their Zanpakuto.
It seemed like they weren't affected much.
But they knew the impact on them was far more severe than what the ordinary Shinigami could see.
True, they could perform Shikai.
But that was all they could do.
Without the cooperation of their Zanpakuto, they simply couldn't achieve Bankai!
In this state, their strength was at most sixty percent of their peak.
Yamamoto's gaze swept over the Gotei 13's Captains, his eyes showing both satisfaction and pride.
These were his subordinates!
Although there were traitors like Aizen, Tosen, and Gin, when it came to protecting the Seireitei, more Captains would step forward.
Compared to the Gotei 13's Captains, Kyoya's Revolutionary Army's members fell short.
At this moment, they all huddled behind Koga, with no intention of fighting the Gotei 13 Captains.
"Kyoya!"
"I will personally take action today to lock you away in Muken!"
"Captain-Commander Yamamoto, rather than fighting me, you should deal with these 'partners' of yours first!"
Facing the Captain-Commander who had already released his Zanpakuto, Kyoya had no intention of continuing to fight him.
His purpose for coming to the Seireitei was mostly accomplished now.
It was time to return.
"Don't think about escaping!"
Seeing Kyoya begin to sheathe his Zanpakuto, Yamamoto roared, swinging his flame-wreathed Ryujin Jakka down at Kyoya.
Boom!
Intense flames bloomed. The surrounding air was baked by the scorching heat, creating visible ripples.
"Ryujin Jakka!"
Kyoya did not make a move. What blocked Yamamoto was his own Zanpakuto's Spirit, Ryujin Jakka!
Roar!
Clearly, similar to Yamamoto, Ryujin Jakka also had a fiery temper. It didn't communicate with the Captain-Commander at all. Its Zanpakuto also erupted with fiery shadows, engaging Yamamoto in battle.
"Let's go."
"Let's retrieve Ashido and Ichinose."
Ignoring the battle between Yamamoto and Ryujin Jakka, Kyoya spoke to Koga and the others.
"Yes, Kyoya-sama."
Now that most of the Gotei 13 Captains were gathered at Sokyoku Hill, the members of the 9th Division and the 6th Division alone couldn't possibly stop the Revolutionary Army group.
"Don't think about escaping!"
Sui-Feng was furious.
In this Seireitei upheaval, she was probably the most frustrated.
Her fight with Kukaku, though unfinished, felt like a loss to her as the Captain of the Onmitsukido, since her Shunpo was inferior to Kukaku's.
She lost her fight with Yoruichi.
But receiving her Yoruichi-sama's recognition made her happy.
She lost her fight with Ichigo, even after using Shunko.
So, she couldn't defeat anyone, was that it?
Did they really think her Bankai was just for show?
"Wait until you survive the attacks from your own Zanpakuto before saying that to us!"
Kyoya waved his hand in Sui-Feng's direction and then led the group towards the 6th Division's location.
However, Kyoya soon stopped.
"Koga, I'll leave the next steps to you."
"Mm."
Koga nodded.
Clearly, he was one of the people who knew why Kyoya stopped.
As for the others, although curious, they knew now wasn't the time to ask.
The materialized Zanpakuto could only prevent the Captains from using Bankai until they made them submit again.
But if a real fight broke out, the Zanpakuto would certainly be no match for the Shinigami.
All Shinigami who completed Bankai Training had essentially made their Zanpakuto submit through battle.
The current situation was just making them undergo Bankai Training again.
Furthermore, Koga's Zanpakuto, Muramasa's Bankai, had a negative side effect.
If a brainwashed Zanpakuto was defeated again by its master, it would return to its master's side and fight in coordination with them.
At least, before they completely disappeared due to the ability's influence, the Shinigami could have the help of their own Zanpakuto, allowing them to exert greater combat power.
Even letting these Zanpakuto fight independently, they were powerhouses surpassing Lieutenant-level and could entangle with real Captains for a while.
If they didn't rescue Ashido and Ichinose and leave the Seireitei before the Captains defeated the materialized Zanpakuto, they would be in danger.
After all, judging from Yamamoto's attitude earlier, he was truly angry.
...
"Hahahahaha..."
Amidst maniacal laughter, Zaraki charged forward recklessly, advancing towards Kyoya's location.
Everything blocking his path, whether walls or tall buildings, was violently broken through by Zaraki.
Kusajishi Yachiru clung to Zaraki's shoulder, unusually quiet and not disturbing him.
In fact, when the Reiatsu conflict erupted at Sokyoku Hill earlier, Zaraki had already set out from the 11th Division.
However, under Yachiru's guidance, no matter which direction they chose, they always ended up in dead ends.
After sensing Kyoya's Reiatsu starting to leave Sokyoku Hill, Zaraki knew that if he couldn't intercept this guy before he left the Seireitei, he would probably miss the chance to fight Kyoya.
Therefore, Zaraki simply stopped looking for a path and charged straight towards Kyoya's direction.
Yachiru could sense Zaraki's current mood and naturally didn't give random directions for their path, lest she deprive Ken-chan of the joy of battle.
Zaraki was not disappointed, as Kyoya's Reiatsu had remained stationary there.
"Hahahaha, Kyoya, you bastard must be itching for a fight too!"
"I've been waiting decades for this battle with you!"
Boom!
Amidst the maniacal laughter, Zaraki's figure burst through the building beside Kyoya. He raised his Zanpakuto high and brought it down on Kyoya.
Kyoya drew the Zanpakuto at his waist and swung it upwards-
Boom!
Their blades collided. Tremendous force erupted from the point of contact between Kyoya's and Zaraki's Zanpakuto, creating a powerful shockwave. The buildings around them were directly shattered by this shockwave.
…
Within the dust and smoke, a small figure flickered among the rubble and finally settled on a tall building in the distance.
The current Lieutenant of the 11th Division, Kusajishi Yachiru.
Having found a good vantage point, Yachiru placed her hand above her eyebrows and squinted her eyes.
"Ken-chan is so happy..."
Below, after the initial clash, a trace of confusion flashed in Zaraki's eyes.
Why did the Zanpakuto in Kyoya's hand feel wrong?
He remembered Kyoya's sword didn't look like this before, did it?
However, Zaraki soon cast this confusion aside.
Who cares?
All he wanted was to fight Kyoya.
As for what kind of sword Kyoya used, that was Kyoya's freedom.
"Hahahahahaha..."
Amidst the maniacal laughter, Zaraki continued his assault on Kyoya.
Clang, clang, clang, clang, clang-
After the initial clash of power came the rapid sound of clashing blades.
Even with Yachiru's eyesight, she could no longer clearly see Kyoya's and Zaraki's sword swings. She could only see the sparks flying from their clashing blades and the buildings around them being destroyed by the aftermath of their battle.
Swoosh-
This was the sound of Kyoya's Zanpakuto slicing across Zaraki's body.
Clang-
This was the sound of Zaraki's Zanpakuto striking Kyoya's body.
Kyoya's sword, slicing across Zaraki's body, could draw forth sprays of blood.
But Zaraki's sword, sliding across Kyoya's body, could only produce sparks.
If an ordinary person encountered such a situation, they would probably be too frightened to maintain any will to fight.
After all, if one's full-power attack couldn't even break the enemy's defense, what was the point of fighting?
But Zaraki was different.
The stronger his opponent, the more excited he became.
Moreover, Zaraki could feel that this battle with Kyoya was different from all their previous encounters.
