One Piece: Kaido's adopted son, starts with the Eight Gates Formation.

Byakuya was speechless for a long time after hearing that.

The white-bearded man watched from the side and laughed out loud: "Gurrah... kid, this irresponsible attitude of yours will cause big problems later."

"We'll see when the time comes." Lynn always disregarded Whitebeard's advice.

He jumped down from the throne and floated to Hyosube Ichibei's side.

"Monk, please open the door for me again."

Hyobu Ichibei held the lollipop, his expression troubled.

He was one of the people who understood Aizen's danger best. But he was also the one who knew best that "Lynn couldn't be stopped."

"...Please come with me."

The group descended into the Avici Hell once again.

This time, it was much faster—because Hyosube Ichibei had already drawn a circle once before, and the eight layers of the barrier hadn't fully recovered yet, so it was opened with a single poke of the lollipop.

The eighth floor, a white space.

Aizen remained seated in the black, sealed chair, smiling as he waited.

"You're back. So soon this time?" Aizen's tone was as if he were asking an old friend, "You've come again."

"I've decided to let you out," Lynn said bluntly.

Aizen's smile paused for an extremely brief moment—if Lynn didn't have omniscient eyes, she wouldn't have noticed it at all.

"...faster than I expected," Aizen said softly.

"But there are conditions."

"Please speak."

"First, you help me manage these Shinigami. They're too stupid; they can't even manage themselves." Lynn pointed to Yamamoto, Kyoraku, Byakuya, and the others behind him. The captains' expressions instantly became incredibly interesting.

"Secondly, you are not allowed to use your 'illusory beauty' on my people."

"Sure," Aizen agreed readily.

"third--"

Lynn floated up to Aizen and looked him in the eye.

"You must be obedient."

Aizen looked into Lynn's eyes. There was no threat, no command in those silver-white pupils, only a simple sense of "what I say goes" and that's perfectly natural.

Aizen thought for a long time—about three seconds. For him, three seconds was enough time to come up with a hundred escape plans and three hundred ways to betray.

But in the end, he only said one sentence.

"I'll be good."

Lynn nodded.

He stretched out his finger and gently touched the sealing band on Aizen's body.

The strap is broken.

hum-

A spiritual pressure that had been suppressed for many years was released from Aizen's body. It wasn't very strong, but its texture was extremely terrifying. That spiritual pressure spread like water, quiet, silent, and omnipresent. Every Shinigami present felt goosebumps—this feeling was all too familiar to them.

Aizen Sousuke's spiritual pressure. Even after being sealed away for many years, it remains their deepest nightmare.

Aizen stood up.

He cracked his neck, making a few crisp sounds. Then he moved his wrists and ankles, like an office worker stretching after getting up.

"I haven't stood up in years," he said calmly. "My body's a bit stiff."

"You look like you've never turned it off," Akainu said coldly.

Aizen glanced at Akainu, smiled, and did not respond.

His gaze swept over everyone present—Kaido, Whitebeard, Big Mom, Akainu, Aokiji, Kizaru, Kenpachi Zaraki, Yamamoto, Kyoraku, Byakuya, and Hyosube Ichibei—and finally settled on the Soul King.

The Spirit King had returned to human form and stood quietly to one side. His face was calm, his eyes devoid of hatred or resentment, only displaying a serene tranquility that had finally been emptied after countless years.

Aizen looked at the Soul King and remained silent for a while.

"You're free now." He used polite language.

The Spirit King nodded slightly.

"He keeps his word," the Spirit King said in a hoarse voice, uttering his third sentence in millions of years. The first two were "thank you" and an answer to Lynn's question.

Aizen understood. The Soul King was saying—Lynn's promise was true, he had indeed been released.

"It seems you've chosen a better master than me," Aizen said in a low voice, his voice carrying an extremely complex emotion.

Then he turned to face Lynn and bent over at a ninety-degree angle.

A perfect bow.

"Aizen Sousuke, from this day forward, you shall obey the young master's orders."
