Aizen quickly made a judgment about Tsugikuni Yoriichi in his heart.
He had to admit that at this moment, Tsugikuni Yoriichi's threat was far greater than Yamamoto Genryusai's.
Yamamoto Genryusai didn't dare to use Bankai, so he was naturally not a concern.
But Tsugikuni Yoriichi was completely different; his Zanpakuto was the most unique Aizen had ever seen.
Ignoring differences in spiritual pressure and ability, whether you were an illusion type, Kido type, or direct attack type, once hit, you would have some connection with Hell.
If your spiritual pressure was lower than Tsugikuni Yoriichi's and you were detected as having sin, you would be forcibly sent into Hell Gate.
This judgment was not made by Tsugikuni Yoriichi, but by Hell itself.
Aizen, being particularly concerned before, had carefully studied it and finally concluded that even he would be affected.
That's why he tried his best to downplay his presence, but he didn't expect to still be hit.
Now that even Kyōka Suigetsu had been seen through, Aizen overturned all his previous views on Tsugikuni Yoriichi, and at the same time, an idea lingered in his mind.
—This kid is definitely an anomaly.
Thinking of this, Aizen slowly raised his head, a smile appearing at the corner of his mouth: "Very interesting."
"Can you tell me how you saw through Kyōka Suigetsu?"
"Kyōka Suigetsu?" Tsugikuni Yoriichi appeared in front of him, his tone full of confusion, "What is that?"
After speaking, he seemed to have thought of the key point, "Are you talking about hypnosis?"
"Sorry, I didn't see through it; I just knew you were here."
"Vice-Captain Aizen, I didn't expect you to be the true culprit behind everything. What exactly are you and Tōsen Kaname plotting?"
"You don't know?" Aizen asked, simultaneously blocking the incoming slash.
He chuckled softly,
"So that's it. You only found out about the anomaly in the Fifth Division and followed the clues to me, rather than knowing my entire plan…"
"It seems Tōsen Kaname didn't tell you everything."
"Kaname respects you greatly, but you're using him like this, Aizen. Don't you feel any remorse?"
Tsugikuni Yoriichi swung his blade swiftly, shattering every illusion that appeared before him.
All of his attacks were directed solely at Aizen.
Aizen barely managed to resist with his superior spiritual power. Without Kyōka Suigetsu, even with his profound techniques, he found it difficult to gain the upper hand against Tsugikuni Yoriichi's powerful attacks.
Aizen's peripheral vision swept over Yamamoto Genryusai, who was affected by Kyōka Suigetsu and dared not step forward, and he chuckled softly:
"Remorse? Heh, what's that?"
"Tsugikuni Yoriichi, your thinking is far too naive. In the face of a lofty ideal, everything can be sacrificed, and everything that can be used can be used."
"You and I stand on different heights, so your questions are meaningless."
"If you could see everything I see, you would naturally come to the same conclusions as me…"
"Unfortunately, like Yamamoto Genryusai, you are both unable to break free from the shackles of the Shinigami."
"I don't know how an anomaly like you came into being, but with your current strength, it's still too early to try and keep me here."
Aizen unleashed a full-powered sword strike, then extended his hand: "Hado #91: Senjū Kōten Taihō."
Countless massive light cones burst forth from in front of him. These light cones looked ordinary, but each possessed the power to destroy a mountain.
Once they hit an enemy, they would cause countless explosions, not stopping until the target was blown to smithereens.
A faint sense of crisis surfaced in Tsugikuni Yoriichi's heart. He instantly vanished, using Dankū for defense.
Dankū was instantly blasted through, erupting in dense roars.
It wasn't until he used multiple Dankū that he finally managed to completely block it, and by then, Aizen had already distanced himself. His voice calmly resounded:
"Tsugikuni Yoriichi, I have to admit, your ability is quite troublesome."
"Currently, I cannot break free from Hell Gate's grasp."
However, according to my research, your seemingly flawless ability also has a flaw."
"The so-called burning is merely Hell's mark. Hell will continuously draw spiritual pressure from the marked person."
"But what if…"
"I reach a place where even Hell cannot set foot…"
"Will the mark still be effective?"
As he spoke, with a "rip," the clouds in the sky were torn open, and along with the space, a massive black void appeared. Several enormous Menos Grande emerged on the other side of the void.
At the same time, a beam of warm yellow light shone down, and Kyōka Suigetsu's ability completely failed at this moment.
Yamamoto Genryusai saw Aizen, and also saw the Negación that was about to cover Aizen.
He didn't have time to roar in anger, or even use Shunpo.
At this moment, he finally understood why Aizen dared to appear alone in front of him, and so unhurriedly.
It turned out he had colluded with those Menos Grande.
This had never happened in history, because it meant that the Menos Grande considered him a comrade. Aizen had completely betrayed the Shinigami, even abandoning his Shinigami identity.
—An absolute heretic!
He wanted to use Bankai.
However, someone used it before him.
"Bankai."
In an instant, the Negación that was covering Aizen missed.
Aizen's body, due to the covering of the domain, fell into a silent, dark space.
The surrounding chains rattled.
Aizen looked around, pushed up his glasses, and a hint of solemnity appeared in his eyes.
"Bankai?"
Recalling everything that had just happened, his brow furrowed slightly: "So that's it…"
"The burning is not only Hell's mark, but also your mark…"
"Once Bankai is used, any creature marked by you, no matter how far away, will instantly be pulled into this space by you…"
"But do you think this will be enough to restrain me?"
Aizen's eyes reflected Tsugikuni Yoriichi's changing attire.
Although Tsugikuni Yoriichi's spiritual pressure had increased significantly, he had not yet reached the pinnacle of a Shinigami, and the medicine was still in effect, so he was not a concern.
Because every Bankai has a weakness.
…
Outside.
"This kid!"
Yamamoto Genryusai was amused by his anger.
He didn't expect Tsugikuni Yoriichi to act so decisively, using Bankai a step ahead of him.
Admittedly, at such a critical moment, it didn't matter who used it, but the problem was that Tsugikuni Yoriichi's spiritual pressure was still a considerable distance from Aizen's.
The previous battle did not prove Aizen's true strength, as he clearly hadn't used his full power.
Now… Thinking of this, Yamamoto Genryusai fell into deep worry, then sighed heavily:
"So be it."
Bankai had already been used; saying anything more was meaningless.
The immediate priority now was…
"Creak…"
Yamamoto Genryusai gripped his sword hilt tightly, slowly raising his gaze. The several Menos Grande in sight were so hideous.
"Bang!"
Flames blazed fiercely on his blade. He instantly stomped the ground, soaring into the sky, his eyes revealing determination and ruthlessness.
"Ryujin Jakka: Jōkaku Enjō!"
