He could see me?
But how could he see me?
I clearly released Kyoka Suigetsu's Shikai right in front of him. He should have been completely under my hypnosis by now!
One question after another surfaced in Sosuke Aizen's mind, leaving him utterly bewildered and incredulous.
The situation before him had clearly gone far beyond anything Sosuke Aizen had expected.
For some reason, he felt as though Gilgamesh's wine-red eyes could see right through him.
His heart began to race, and the hand he had reached toward Gilgamesh froze in place.
Gilgamesh slowly spoke. "Kyoka Suigetsu's true ability is Complete Hypnosis."
"It allows you to control your opponent's five senses, making them believe whatever you want about a specific target's appearance, shape, weight, texture, or even scent."
"Anyone who sees the moment Kyoka Suigetsu is released will fall under Complete Hypnosis. After that, whenever Kyoka Suigetsu is released, they'll be hypnotized again."
When Gilgamesh revealed the true ability of Kyoka Suigetsu's Shikai, Aizen's pupils contracted sharply behind his glasses. A chill swept through his entire body.
After all, Sosuke Aizen had never told anyone the true ability of Kyoka Suigetsu's Shikai—not even Gin Ichimaru and Kaname Tosen, who had already pledged themselves to him.
He was extremely cautious. Until he had gathered enough strength, he would never reveal his trump cards.
Then why did Gilgamesh know the true ability of Kyoka Suigetsu?
"Who are you, exactly...?"
As the thought crossed his mind, Sosuke Aizen couldn't help speaking up to demand an answer.
But before he could finish, Gilgamesh continued, "There are two ways to counter it. First, avoid seeing the moment the Shikai is released. Second, touch the blade before Complete Hypnosis takes effect."
He knows. He knows everything!
Aizen screamed inwardly.
At that moment, his killing intent toward Gilgamesh reached its peak.
What interest? What experimental subject? What research? What ancient King of Heroes...? None of that mattered anymore.
The only thing he wanted now was to kill Gilgamesh, no matter what it took!
The only problem was how to kill him.
This was the Shin'o Academy.
Although he had already hypnotized all the students in Class 1-1, the hypnosis only affected that class.
Sosuke Aizen couldn't see through Gilgamesh at all. He couldn't be sure that he could kill him instantly.
If he failed to kill him at once, the commotion from their battle would inevitably attract attention.
And then, Sosuke Aizen wouldn't be able to explain himself.
He had spent hundreds of years plotting in the Soul Society. He couldn't accept having all his plans fall apart.
What should he do...?
Sosuke Aizen's mind raced as he searched for a solution.
His face had grown far more grim than usual. His eyes, hidden behind his glasses, were fixed on Gilgamesh, and an oppressive, suffocating aura radiated from him.
Just then, Gilgamesh suddenly stood and walked toward the Garganta.
As he stepped into it, Gilgamesh turned to look at Sosuke Aizen, whose face had gone slack with astonishment, and said, "Come. This king will show you exactly how he'll conquer you."
Hearing Gilgamesh's words, Sosuke Aizen first froze. Then his pupils contracted again, and he thought to himself, He can even tell what I'm thinking!?
Sosuke Aizen had already found Gilgamesh completely inscrutable.
He hadn't expected that meeting Gilgamesh wouldn't lift the veil of mystery around him at all. Instead, it had only made him seem even more mysterious.
But Sosuke Aizen said nothing.
He didn't know what gave Gilgamesh the confidence to step into the Garganta, but that suited him just fine.
As soon as Gilgamesh entered Hueco Mundo...
No. He would make his move inside the Garganta. He wouldn't give him any chance at all!
Without hesitation, Sosuke Aizen followed him, entering the Garganta behind Gilgamesh.
Once Sosuke Aizen had entered, the open Garganta gradually closed.
Meanwhile, the students in the classroom continued to face the teacher's podium. Their expressions had simply turned vacant and lifeless. They no longer spoke or interacted, like empty shells without consciousness.
Renji Abarai and Rukia were the same.
Gilgamesh knew, of course, but he wasn't worried.
Aizen had only hypnotized them. He hadn't harmed them.
Inside the Garganta, Sosuke Aizen watched Gilgamesh in the distance. He was just about to attack when a dazzling golden light suddenly flared.
As Aizen stared in shock, a gigantic golden ripple appeared out of thin air behind Gilgamesh.
Then the Throne of the Heaven-Soaring King—Vimana—slowly emerged from the enormous golden ripple.
What is that? Is it the ability of a Zanpakuto?
The moment the thought crossed his mind, Sosuke Aizen dismissed it.
He couldn't sense any spiritual pressure from either the golden ripple or Vimana.
At the same time, he couldn't help admiring Vimana's splendor.
Suppressing his astonishment, Sosuke Aizen feared that hesitation might lead to trouble. He raised his hand toward Vimana as spiritual pressure surged throughout his body.
The tremendous spiritual pressure made even the Garganta tremble. Without chanting, he called out, "Hadō #90—Black Coffin!"
In the next moment, a dark coffin forged from immense spiritual pressure enveloped Vimana. Countless Shadow Blades shot from within it, striking at Vimana and Gilgamesh.
Soon, the Black Coffin began to dissipate.
As it faded, Vimana's radiance blazed anew, illuminating the Garganta.
The sight made Aizen's heart sink.
When he saw Vimana completely unharmed, with Gilgamesh seated on its throne, Aizen's heart sank to the very bottom.
Although his Black Coffin had only one-third of its full power without the incantation, it was still strong enough to defeat a weaker captain in a single strike.
But this only strengthened Sosuke Aizen's resolve to kill Gilgamesh.
Before Sosuke Aizen could attack again, a missile shot from Vimana straight toward him.
He instinctively raised his Zanpakuto to defend himself, when Gilgamesh's amused voice rang out. "Aizen, enjoy the full power of this Ancient Nuclear Warhead."
Aizen's raised hand abruptly froze. An expression of disbelief spread across his face, as if he doubted his own ears.
What did I just hear?
A nuclear bomb? That projectile in front of me is a nuclear bomb!?
