"Why isn't that guy moving?" Grimmjow noticed that Kenpachi Zaraki had suddenly become still, not just in the usual sense of inactivity, but to the point that even his soul fluctuations were almost gone.
Grimmjow's body had cooled down, and regardless of Kenpachi Zaraki's condition, it wouldn't hurt to mess with him. So, the Azure Lightning reappeared, but this time, upon reaching the same distance as before, Kenpachi Zaraki didn't attack.
Grimmjow stopped. "Going any further is no joke. How can there be such a freak with Explosion attack power? It's disgusting, completely devoid of any graceful skill."
However, Grimmjow was unwilling to give up without exploring further. If he retreated here, wouldn't that be cowardice? His fighting style could be roundabout, because that was his advantage, but his State of Mind could not be. Retreating without a fight was absolutely unacceptable.
"Victory will be mine! It can only be mine!"
So Grimmjow moved forward slowly, like a leopard that, having chosen its prey, followed it with a slow, deliberate gait, concealing its tracks while searching for the perfect moment to strike.
While physical endurance is never a leopard's strong suit, its mental stamina is Kongbu. The jaguar, which shares the same name as the lion, will die of frustration after seven failed hunts, but the cheetah won't. Of course, it's also unlikely for a cheetah to fail seven times in a row, because it is more patient and cautious.
The two closed the distance between them, Grimmjow's steps became increasingly steady. He feared no one in terms of reaction time; even that silly eagle (Healdos) was no match for him, let alone anyone else.
His Reiatsu is also completely contained; this is Grimmjow's true innate ability. The bursting out of his spiritual pressure is merely a matter of his constitution. Grimmjow's innate ability is called Vanishing Reiatsu. When needed, he becomes completely undetectable by any method of probing Reiatsu, and he can also make a portion of his Spiritual Power undetectable.
So, unexpectedly, he walked up to Kenpachi Zaraki. Kenpachi Zaraki was currently encased in a hard shell of demonic energy, his entire body shrouded in a blood-red aura, and even his body seemed to be being dissolved by the demonic energy.
"This is the first time I've ever seen Reiatsu of this magnitude," Grimmjow exclaimed, his worldview shattered by Kenpachi Zaraki. "How can there be Reiatsu more concentrated than Cero?! Are you even human?"
However, Grimmjow felt that was enough. After observing closely, he retreated to a distance of about one kilometer and released some Grimmjow Spiritual Power. Sure enough, a storm appeared, completely obliterating the Spiritual Power.
However, Grimmjow was nearly a kilometer away from that Spiritual Power. It was only because he released a small burst of Spiritual Power using his Vanishing Reiatsu and then canceled the ability that it was detected. This ability is only suitable as bait; it cannot render a release of Spiritual Power as strong as Cero undetectable. It has its limits.
However, this test also revealed something amiss. Grimmjow stared at Kenpachi Zaraki and released a trace of killing intent. Instantly falling silent, the Demon King seemed to have crossed space to arrive at the spot where Grimmjow had just been, and then with a single strike, this time plunging into a massive abyss several kilometers deep.
Grimmjow could control his murderous aura with ease; a good hunter is one who can conceal all outward signs of his presence. He's an assassin, devoid of emotion.
"This guy can now sense everything directed at him, and he's incredibly strong, but... he's lost his self-awareness. What's his consciousness doing? Could it be...?"
Grimmjow clapped his hands
"This guy is the same type as Kanō Miyabi? Neither of them can control their power? And the release has a backlash effect? Very likely!! Hehe~ What an interesting Soul Reaper."
Grimmjow was the last and penultimate Arrancar to be born, over a hundred years ago; the Arrancar's birth cycle is extremely long. During Grimmjow's training, the Soul Reaper Zennosuke Kuruyashiki and Ashido Kanō naturally observed and provided guidance to the Arrancars, as Soul Reaper are generally more proficient in human combat.
In the original work, Ashido Kanō is a brute capable of dismantling Adjuchas with his bare hands. His Shikai) was achieved gradually over a long period, reaching Permanent Shikai, which is quite unique. Ashido Kanō's Shikai is actually his fur coat.
His release also occurred over a long period of time, but unlike his Shikai, its power is somewhat similar to Kenpachi Zaraki's, yet different. Ashido Kanō's release possesses its own consciousness; after releasing, he transforms into a red, furry monster that is often out of control.
Ultimately, with the help of the Mindset Zanpakuto State of Mind Series, Ashido Kanō entered the Inner World to subdue his sword and regain control of his Release. Grimmjow of this process because he was still alive at that time.
"Hehe~", Grimmjow chuckled wickedly. Actually, Grimmjow didn't harbor much ill will towards the Soul Reaper. The Arrancar who emerged from the Endless Sea all possessed a fairly mature worldview, and were inevitably influenced by Pure's ideology.
Grimmjow's reason for leaving the Endless Sea was very simple: he loved killing, hunting, and excitement. The peaceful life of the Endless Sea was like a retirement home to him—what a joke! He was still only a hundred years old! How could he retire so young!?
His reason for joining Aizen was equally simple: Aizen was clearly a troublemaker, and following Aizen meant constant trouble, leading to many battles. Aizen was so powerful; his opponent couldn't be too weak, right? And now it seemed that was indeed Aizen case. Grimmjow had indeed found a treasure.
The battle had stalled. He was helpless against Kenpachi Zaraki's current state. If Kenpachi Zaraki were conscious, this state would eventually end, but right now it was clearly a battle within the Inner World, and it would only drag on endlessly.
Hunting rhinos is fine, but hunting tanks is just idiotic. However, Grimmjow is, at his core, a big cat, and mischief is part of a feline nature.
Grimmjow returned to Kenpachi Zaraki's side, slicing open his own palm and letting his eerie blue blood flow onto Kenpachi Zaraki's demonic energy. This blood, pure and unadulterated Spiritual Power, carried no hostility and simply seeped into Kenpachi Zaraki's body.
"Hehehe~, since you're fighting in the Inner World anyway, it doesn't hurt for me to add a little something extra, right? Thank me, the Visored Amplification from my blood is absolutely Kongbu."
"Isn't it Kongbu? But the Visored that Kuruyashiki and Kanō Miyabi created using the blood of Oka and Starrk are quite powerful. My blood isn't any weaker than theirs. We're both Arrancar, there's no reason for me to be weaker! Yes, there's no reason!"
Grimmjow glanced again at the still silent Kenpachi Zaraki, scratched himself a couple of times, creating several wounds. "My calculations show I won the battle, and with a few minor injuries, I can go back and explain myself. Aizen's insight is really annoying."
In the Inner World, Kenpachi Zaraki is always fighting, always fighting. He is Shura, he is a demon, but in the beginning, he was a human.
Because of his own strength, Zaraki had long since skipped the scenes of fighting humans in his Inner World. Sōya Azashiro had also entered this Inner World before; the outer perimeter was full of human corpses, and only further in did various kinds of demons appear.
Zaraki starts directly with demons. Each demon he kills absorbs a portion of demonic energy, which is his training method. Using the Pure State of Mind Series swords, he detaches himself from the Inner World the instant he loses awareness after absorbing demonic energy, gradually increasing his threshold for withstanding demonic energy.
However, Asura King's demonic aura was too strong. Even after more than two months of training, Zaraki could only remain conscious for less than half a minute in his unleashed form. After half a minute, Kenpachi Zaraki would transform into a reaction device, completely annihilating any release of Spiritual Power or killing intent, indiscriminately, friend or foe.
At this moment, in Kenpachi Zaraki's Inner World, he also went mad with killing. In the end, he became the Demon King, endlessly killing. And when the last one was wiped out, that was when he killed himself.
In this phase of self-destruction, who will die? Kenpachi Zaraki? Or Asura King? Or will they perish together? No one knows. But Kenpachi Zaraki knows that he currently does not possess the power to truly conquer Asura King.
Kenpachi Zaraki had completely entered a killing frenzy, and had now reached the Blue Oni stage. Two more stages would bring him to the final Red Oni, and at that very moment, his entire Inner World was stained with a ghostly blue.
The ghostly blue light was gradually absorbed by the Blue Oni wielding the broken sword. Suddenly, the Blue Oni knelt on the ground, howling in agony. A ghostly blue shadow was torn from his body, and then the two separated.
Suddenly, the entire Inner World was altered. The desolate canyon was now empty of corpses, and a Blue Oni, a Red Oni, and Kenpachi Zaraki stood in three different locations.
The Blue Oni wore a panther-shaped Hollowfication Mask, similar to the Black Panther from Marvel, with a white background and dark blue patterns.
"What is this?" Kenpachi Zaraki was completely bewildered. He wasn't suited to thinking about these things and couldn't figure it out.
The two demons remained silent. Kenpachi Zaraki after swinging it a couple of times, he realized it was just a broken sword and had no special abilities.
"I don't understand what this is, but killing you two would be enough, right? Let's find this new blue guy first."
Just as Kenpachi Zaraki charged forward, the Hollowfication Mask Blue Oni produced a similar broken sword, and simultaneously, his entire body swelled with eerie blue Spiritual Power. With a ferocious strike, he cleaved Kenpachi Zaraki away.
Then, with a speed even faster than when Kenpachi Zaraki was knocked away, he caught up and unleashed a series of slashes, one after another, leaving Kenpachi Zaraki overwhelmed.
"Ahhh!" Zaraki roared.
He placed the knife in his left hand, braced himself against the blow with his right shoulder, and the broken blade cleaved into his right shoulder. He used his right arm to brace against the attack, and with that one split second, he grabbed Hollowfication Mask Blue Oni, then with a left-hand strike, cleaved the Blue Oni's head off.
The eerie blue light entered Kenpachi Zaraki's body, Kenpachi Zaraki figure. He donned a leopard-shaped Hollowfication Mask, and the power within him surged rhythmically, wave after wave, like an engine.
Zaraki his injuries, Zaraki lunged at the Red Oni with a sword in his left hand.
"Ah!!"
Within Hueco Mundo, Kenpachi Zaraki was standing still, suddenly unleashed his Spiritual Power, blasting away the surrounding sand and earth. A ghostly blue aura enveloped his entire body, and a bone Hollowfication Mask suddenly appeared on his face.
"Awooo!"
However, another roar followed immediately, Kenpachi Zaraki reverted to his previous released state, but this time, he regained consciousness.
Holding a sword in his right hand and clenching his left, Kenpachi Zaraki looked at his hands and the demonic aura surrounding him. Suddenly, he placed his hand on his forehead, and after a flash of eerie blue light, the demonic aura covering his entire body turned blue as well. He also put on Hollowfication Mask.
"Is this that guy's power? Why?" Kenpachi Zaraki couldn't figure it out, so he stopped thinking about it. "Whatever! Hahaha, anyway, I'm stronger now. At worst, I won't kill him next time I see him. By the way, what's that guy's name?"
