Bleach: The Two Gods of One Family

"What an incredible ability!"

"It's the first time I've seen Katen Kyōkotsu humiliated!"

"No wonder Hirako lost so miserably—even his Bankai couldn't be used!"

"Although none of our Zanpakutō used Bankai either, Aiyan is still just one man, and he hasn't used his Bankai either!"

"That Lord Yamamoto only dared to accept Aizen as a disciple and didn't dare accept Aiyan—it's not without reason. A talent like that… is beyond teaching!"

It wasn't just the lieutenants who were shocked.

Kyoraku Shunsui, Jūshirō Ukitake, and the others, seeing their Zanpakutō so thoroughly dominated, were equally in awe at Aiyan's strength and the ability of his Zanpakutō.

Previously, they had assumed Aiyan's Shikai could only suppress or seal a few Zanpakutō, and only under direct contact—but now, that clearly wasn't the case.

So many captain-level Zanpakutō had been suppressed with just a wave of the hand.

'Ryūjin Jakka… just like in the graduation exam… are you afraid of Aiyan's Zanpakutō?'

'To suppress this many Zanpakutō in a single move… Aiyan's Kōfūin must be the strongest dark-element Zanpakutō.'

'But… for it to cause this level of fear in Ryūjin Jakka… it shouldn't just be 'strongest dark element'...!'

As he listened to the faint echo of Ryūjin Jakka's voice, Yamamoto looked toward the Zanpakutō engulfed by darkness—those that had been materialized by Hypnosis. He was nearly certain that Aiyan's Kōfūin was the most powerful dark-type Zanpakutō.

But even so, he couldn't understand why Ryūjin Jakka reacted with such overwhelming wariness.

Across a thousand years, he'd seen many wielders of the so-called strongest elemental Zanpakutō. Even those who defeated their predecessors weren't enough to make Ryūjin Jakka fear them—at most, they earned its recognition.

But Aiyan's Kōfūin… upon its second release, Ryūjin Jakka's instinct was the same as if it faced a natural enemy.

"Captain Unohana, Captain Ukitake, Captain Kyoraku, Teacher Isshin…"

"Are you not going to retrieve your Zanpakutō?"

"Or… are you content to watch them kneel before me?"

"If so, that's fine. I'll help."

Seeing that Katen Kyōkotsu, Minazuki, and Sōgyo no Kotowari—some of the most powerful Zanpakutō—still dared to struggle, Aiyan raised his hand. Majestic black mist surged skyward, forming a massive palm of pure darkness.

Like the Buddha subduing Sun Wukong, the palm descended and slammed the three Zanpakutō to the ground. Not one could resist—they couldn't even twitch.

"Wait! Wait, I'm coming!"

"Sorry… I was just stunned by your strength…"

"Forgive the trouble, Captain Aiyan."

Unohana Retsu, Kyoraku Shunsui, and Jūshirō Ukitake finally stepped forward, thoroughly ashamed for standing aside so long.

Despite their centuries of experience, they hadn't panicked in the face of a sudden rebellion. In fact, they had acted almost amused.

But after Aiyan called them out, they had no excuse. They immediately began subduing their own Zanpakutō with combinations of Kidō, Hakuda, and Zanjutsu.

"So… subduing your Zanpakutō removes Muramasa's Hypnosis?"

Seeing this, the other captains quickly understood. This was the way to break Muramasa's control.

Taking advantage of the suppression by Aiyan's darkness, they charged forward while their Zanpakutō were weakened and immobile.

In just a short time—

The enormous black mist that had engulfed the 1st Division Headquarters dissipated, and sunlight once more poured down over Seireitei.

Bathed in the golden glow, many captains stared at their Zanpakutō in hand, stunned. It felt like a dream.

A Zanpakutō rebellion that involved eleven captains of the Gotei 13—

Suppressed by Aiyan in less than 5 minutes.

Before the materialized Zanpakutō could even strike, they were sealed and returned to their wielders.

"Kōga, you said Aiyan had no achievements or qualifications. Are you stupid?"

"Aren't you his greatest achievement?"

Kuchiki Ginrei couldn't help looking toward Aiyan—this figure who had stopped a full-scale Zanpakutō rebellion with a flick of his fingers. His heart trembled.

And he felt… unease.

He feared that the secret pact he made with Tsunayashiro Tokinada—the assassination attempt on the Sōsuke brothers—might come to light.

With the Kuchiki family's status, even if it did… they wouldn't fear Aiyan.

But they would gain two enemies for no reason.

And that was troubling.

Especially after this Kōga Rebellion, the Kuchiki family had lost a powerful deterrent—Kōga, a captain-level asset.

Now, all eleven Gotei 13 captains owe Aiyan a favor—including Ginrei himself.

This meant Aiyan wasn't merely the Captain of Squad 5 anymore.

He was now one of the most pivotal forces in all of Seireitei.

Even Unohana, Ukitake, and Kyoraku were now in his debt.

[Your Zanpakutō is overjoyed that you used her to suppress the Zanpakutō of eleven captains.

She feels proud to shine in front of Zanjutsu, Hakuda, Hohō, and Reiatsu.

So, she has decided to reveal to you her Shikai Ultimate Form:

"Heaven and Earth: Submit in Reverence."]

After the rebellion, Kōfūin couldn't contain herself. Thrilled by her moment of glory—suppressing eleven captains—she announced the awakening of her Shikai's ultimate dark form, meant to match the already-revealed light form: "Throne of Heaven, Rule of One."

"Heaven and Earth?"

Aiyan raised his eyes to the sun shining above Seireitei. A flicker of anticipation crossed his gaze.

Neither Kōfūin's Light Ultimate nor her Darkness Ultimate had ever been used.

Not because he couldn't.

But because no one yet had been worthy of seeing them.

"Captain, do we really not need to issue a warrant?"

Chōjirō Sasakibe approached and asked Yamamoto Genryūsai in a quiet voice.

"If Captain Aiyan says it's unnecessary… then I will trust him."

"He will handle it himself."

"The sinner… Kōga."

"There is no need for a public warrant."

"No need to trouble all of Gotei 13."

Yamamoto thought for a moment and agreed to Aiyan's suggestion.

After all—

In under 5 minutes, he had crushed a rebellion involving eleven captains Zanpakutō.

Even Yamamoto Genryūsai, strict as he was, found no flaw in that result.

"…Yes, sir."

Chōjirō Sasakibe nodded.

After witnessing Aiyan's strength with his own eyes, he too felt it would be pointless to mobilize all of Seireitei for a mere 3rd seat from Squad 6.

There was no need.

Because Aiyan alone could handle it all.

Rather than waste time and effort—

Better to leave everything… to him.
