Gin Ichimaru's Bankai, Kamishini no Yari, was neither as fast nor as long as he had told Aizen.
In the blink of an eye, the blade turns to ash, and then a deadly poison capable of dissolving cells appears inside.
This is the source of Gin Ichimaru's confidence in lurking beside Aizen.
But he couldn't wait for the right opportunity to make his move.
To break the Kyōka Suigetsu, strike hard when Aizen is most relaxed.
In Gin Ichimaru's plan, only by meeting these two conditions could he deliver a fatal blow to Aizen.
He spent decades trying but never managed to gather all the necessary conditions.
Knowing that Gin Ichimaru was rebellious, Shiraishi used his abilities to help him.
Aizen was right.
PROJECT's skin ability is to hypnotize others; anyone who focuses their attention on the aura will be controlled by the electromagnetic waves emitted by the aura.
Shiraishi can analyze through the Y-shaped lens to obtain the most favorable image for himself, thereby manipulating the hypnotized person to complete that image.
He cannot personally participate, as that would interfere with the hypnotic signals.
The specific control time depends on Reiatsu. For Aizen's level, half a second is already the limit.
His choice to use this opportunity at this time, by having Gin Ichimaru help, instead of having Genryūsai Shigekuni Yamamoto and the others take action from the beginning, was naturally a matter of vigilance.
An overwhelming sense of danger will cause the hypnotist to instinctively feel a slight resistance, thus prompting them to wake up.
The attacks from Genryūsai Shigekuni Yamamoto and his group were too powerful and direct, far less insidious and deadly than those from Gin Ichimaru, which could easily lead to accidents.
Therefore, Shiraishi's initial plan was to use the Spirit Blossom skin ability to defeat Aizen.
Who could have imagined that Genryūsai Shigekuni Yamamoto and his group would collapse so quickly? And with Aizen forcing him into a corner, he had no choice but to improvise, choosing the PROJECT skin and having Gin Ichimaru act as his ally, to see how things went.
As it turns out, Gin Ichimaru's Bankai, Yinren, is truly unstoppable.
"Shoot him, Kamishini no Yari!"
The blade remaining in the heart turned to ash, releasing a deadly poison. Aizen's body cells dissolved, and his heart, lungs, part of his internal ribs, and so on, all disappeared.
Even the shoulder of his left arm had dissolved, leaving a very large hole.
Such a fatal injury caused even Aizen to momentarily lose his composure, slightly delaying the healing process.
Gin Ichimaru frowned slightly. The Hōgyoku wasn't there. Shiraishi transformed into the Nightbringer, unleashing orange karmic flames that burned the melting wounds, preventing them from healing again.
"Aaaaaaah!"
Aizen roared, sensing a deadly crisis. A surge of Reiatsu erupted outwards, and a pillar of light pierced through the heavens and earth.
Gin Ichimaru couldn't even get close.
Shiraishi withstood the substantial Reiatsu, even his dark golden skin began to crack, with only one thought in his mind: he could not let this opportunity slip by!
If Aizen were to recover, the difficulty would double, as his Bankai remains a mystery.
Shiraishi swung his sword again and again, the engulfing flames slicing Aizen into several pieces, even his head was cleaved into hundreds of pieces.
Blood splattered.
The orange flames scorched Aizen, making him unrecognizable, and his Reiatsu continued to emanate outwards.
"Go to hell!"
Shiraishi roared, "Takashi, do you have to be this stubborn?!"
Wave after wave of karmic fire steadily scorched Aizen's soul and body—no, to be more precise, his flesh.
The excruciating pain rendered Aizen unable to think. His instinctive release of Reiatsu couldn't last long and began to weaken, his roars gradually ceasing.
Shiraishi swung his knife faster and faster, reducing the chunks of meat to minced meat. Then, even the last bit of minced meat burned away, disappearing from the world along with that faint trace of Reiatsu.
"Ha ha"
He gasped for breath, beads of sweat forming on his forehead. He carefully sensed his surroundings, confirming there was no Aizen's Reiatsu, but he was still somewhat unsure. "Is that guy dead?"
Even he couldn't survive under such circumstances.
Gin Ichimaru was certain.
"Phew, dead... damn it."
Shiraishi slapped his forehead. He had really lost his mind; he had been so focused on killing Aizen that he had forgotten something very important.
Hell!
Does Aizen meet the requirements to go to Hell? He wasn't sure. Aizen wasn't Shinigami, a Hollow, a human, or Quincy; he was an existence like the Soul King.
Who knows if that person will be taken to Hell?
Just thinking about the possibility of him being resurrected gave Shiraishi a headache; that guy would probably become the King of Hell.
"Oh well, let's talk about the future later."
Shiraishi scratched his head, deciding not to think about those problems and let Kisuke Urahara and the others worry about whether Aizen would make a comeback.
He should focus on caring for the people he should care about.
His Spiritual Sense senses had expanded, allowing him to pinpoint Retsu Unohana's location, and he used the Steel Tempest to rush over.
... This is the bedroom of a female Arrancar; inside the open wardrobe hangs a series of beautiful clothes.
Retsu Unohana struggled to put on the dress; not only was it difficult to put on clothes because of her one arm, but the dress was also a bit too small.
The heights are similar, but the chest measurements don't match; the original owner was most likely flat-chested.
It made her feel tightness in her chest, as if bending over could cause her chest to split open.
She didn't have time to keep picking and choosing; the Reiatsu Aizen had just unleashed proved that the battle was intense.
Now that things have calmed down, Retsu Unohana just wants to get to the scene as soon as possible to check on things. She reached behind her with her left hand and forcefully zipped up the back of her zipper. "Ugh!"
She looked at the blue fabric that looked like it was about to tear in the mirror, turned around, and a gentle breeze blew in her face.
The sun shone brightly outside the window. A gentle breeze brushed her thin lips, and her eyes brimmed with tender affection. "You won?"
"Um"
Shiraishi pretended she hadn't kissed him before, and said, "Come with me."
He reached out and grabbed her right hand, wanting to leave.
Retsu Unohana retorted, "Stop fooling around. Now is not the time for that kind of thing. I'll reward you later."
"... What are you thinking?"
Shiraishi retorted, "I sent you to rescue people."
As he spoke, he didn't stay there. Grabbing her soft wrist, he pulled her outside. Like a fallen leaf carried away by the wind, Retsu Unohana followed him to a dilapidated hall.
It's very dark here.
The ceiling was cracked, and stones larger than the house had fallen to the ground, forming ruins that obstructed people's view.
A cry echoed in the air, like the mournful voice of a wronged spirit, "Lady Nel, please wake up!"
With a casual swing of his sword, Shiraishi shattered the obstructing rocks, revealing the figure that had been blocking the way.
Retsu Unohana looked ahead and saw a woman with Arrancar leaning against a piece of upright rubble. Blood gushed from the wound that had almost torn her upper body, pooling on the ground.
Her long, lake-green hair was now stained with dust and blood, losing its former shine.
A blond-haired Arrancar and a black-haired Arrancar stood around each other, crying bitterly.
"Lie, please save Nel! She's my best friend!"
Shiraishi urged anxiously, saying with great dissatisfaction, "That Zaraki guy really doesn't know his own strength!"
"You guys have such a great friendship. I don't even have one hand, and you haven't said a word about it."
Despite verbally criticizing his behavior, Retsu Unohana walked over there anyway.
Her belief was that even defeated enemies should be healed, albeit afterward, by being the Jail.
Shiraishi was taken aback, then quickly explained, "With Inoue there, I believed she could help you recover your arm, which is why I didn't say anything."
Hey, you guys stop right there!
Pesche jumped out, interrupting their conversation. He drew his Zanpakuto and said menacingly, "If you want to kill Nel, you'll have to step over my dead body first."
Retsu Unohana stopped in her tracks, her face serious, and said, "If she doesn't receive treatment soon, she will die here."
"Do you believe me and let her live, or do you maintain your prejudice against Shinigami and let her die?"
Pesche froze for a moment, then knelt down smoothly and kowtowed, saying, "Please save Nel!"
"Me too"
Dondochakka also knelt down.
They were Nelliel's subordinates, but their relationship was not a simple superior-subordinate one; rather, they regarded each other as family.
As long as Nelliel can be saved, they'd be willing to kneel down and lick the enemy's feet to beg for forgiveness.
I will save her life.
Retsu Unohana Shunpo to reach Nelliel's side, crouched down, and examined the gruesome wound. The remaining Reiatsu was powerful, but it had not damaged her heart.
Kenpachi Zaraki was still holding back.
Retsu Unohana sighed softly to herself, realizing that it was probably impossible to bring him back to his youthful mindset.
If it were that boy from back then, he wouldn't care whether the enemy was male or female; he would only use the most brutal method to kill them with a single blow.
Thinking about these trivial matters, Retsu Unohana placed her hand on the wound, releasing the green light of the Kaidō from her palm to begin the treatment. First, she stabilized Nelliel's weakening Reiatsu to prevent it from dropping further to an incurable state.
" Nel "
Pesche noticed that her Reiatsu had stabilized, so he quickly knelt on the ground and kowtowed, saying, "Thank you. I am willing to lick your feet as a token of my gratitude."
"You want another reward?"
Shiraishi kicked Pesche, who was trying to slide forward, back with one foot.
Pesche quickly covered his bleeding nose and angrily said, "What reward? I sacrificed my manly dignity to grovel."
Wait, you're in cahoots with her, aren't you? Then let me lick you.
"Roll"
Shiraishi kicked the clown away again.
"Quiet down, all of you!"
I need to concentrate.
Retsu Unohana gave a reprimand, and Pesche stopped using his special thought process. He and Dondochakka sat upright on the ground, motionless, for fear of affecting Lady Nel's treatment.
Retsu Unohana's gaze shifted to Shiraishi, "Don't just stand here, go do what you're supposed to do."
"Um... what's up?"
Shiraishi nodded subconsciously, then thought for a moment, unsure of what he should do.
Retsu Unohana said irritably, " Pantheon, but we still have a million Arrancar troops below. We can't let those Arrancar be Quincy or absorbed by the Arrancar."
"Oh, I understand,"
Shiraishi remembered that there was another Arrancar army below.
Aizen's defeat does not mean the end of the battle; how to handle the aftermath remains an issue.
