One Piece: Burning the Prison Clothes in the Setting Sun, Mihawk is dumbfounded.

Soul Society, Seireitei.

With a warm and gentle smile on his face, Aizen leisurely left the Fifth Division's residence.

"Captain Aizen!"

Along the way, every Shinigami they encountered stopped to greet Aizen.

All I can say is that Aizen has played his current identity very successfully.

A captain with a great personality, always gentle and kind to everyone he meets.

The Fifth Division is a division that many aspiring Shinigami would like to join.

This is all thanks to the successful portrayal of Inazuma.

However, after returning from Hueco Mundo, Aizen had been planning to test Dunn, who was in Hueco Mundo.

"That person!"

Aizen smiled and nodded to the surrounding Shinigami as he walked forward, but in his heart he was thinking about how to do things better.

If the goal is simply to hypnotize some death gods to go and die, it's not very useful.

That person was someone who made him feel a great sense of crisis. Sending some weaklings over to such a powerful person would be pointless, not even for observation.

It must be someone who can probe and find out something.

While pondering, Aizen arrived outside the Twelfth Division, which is the Research and Development Bureau.

Captain Mayuri Kurotsuchi of the 12th Division is a freak and a tech fanatic.

However, to become the captain of the 12th Division after Kisuke Urahara, he must have extraordinary abilities.

Aizen wasn't stopped outside; apparently, he had been informed beforehand. He was led directly to see Mayuri Kurotsuchi.

"Captain Mayuri Kurotsuchi."

Aizen smiled and spoke, his voice gentle.

But Mayuri Kurotsuchi was not impressed by his attitude.

"I've looked up some information about what you're talking about, and there's no such person before. Also, I'd like to ask, Captain Aizen, where did you meet such a person? I'd like to see for myself."

As Mayuri Kurotsuchi spoke, he turned and glanced at Aizen.

"I stumbled upon some news, so I became curious."

Aizen shook his head upon hearing this, speaking as if he didn't care much.

Mayuri Kurotsuchi won't work; his behavior pattern is fixed, and rushing into Hueco Mundo would attract a lot of attention.

"Could it be a Quincy's ability?"

Upon hearing Aizen's answer, Mayuri Kurotsuchi clearly did not believe it, but did not ask any further questions and turned back to attend to his own business. Aizen, on the other hand, continued to ask a question.

"no."

Mayuri Kurotsuchi denied it outright, but it was clear that he had no intention of continuing the conversation.

"So, are there two identical knives?"

Aizen's eyes behind his glasses flickered, and he smiled again, asking the question, seemingly unconcerned about Mayuri Kurotsuchi's attitude.

"How is that possible!"

Mayuri Kurotsuchi shook his head immediately.

"As the team leader, don't you even know this basic common sense?"

"But common sense can be wrong sometimes. After all, there's always a first time for everything."

"At most, they may have similar abilities, but everyone's power comes from their own soul, unless two people's souls are exactly the same, but even a created soul cannot do that."

Mayuri Kurotsuchi seemed a little impatient, and then rattled off a long string of words.

"What if it's not the power of death?"

Aizen asked again.

Mayuri Kurotsuchi paused upon hearing this, then turned to look at Aizen, his face expressionless.

"Isn't this what you asked me in the first place? You seem to care a lot. Are you sure you just saw some records somewhere?"

Mayuri Kurotsuchi looked at Aizen with suspicion.

"It's definitely getting a bit boring."

Aizen waved his hand and chuckled.

"Although there are no records, I do not deny that such power exists, but we will only be able to understand it after we see it."

Mayuri Kurotsuchi waved his hand as he spoke, clearly indicating that he did not want to continue talking with Aizen.

"If you actually find something, then come find me. If not, then don't bother me."

Aizen didn't press the matter further and turned to walk outside.

After Aizen left, Mayuri Kurotsuchi turned to look in the direction Aizen had gone.

"Does such power really exist?"

Mayuri Kurotsuchi thought to herself, then turned to look at the girl beside her who resembled a doll.

"What mission has Captain Aizen been on lately?"

"Some missions carried out by each division are classified, but the Fifth Division has not been deployed recently."

The girl's answer was like that of a puppet.

"Could it be that you saw it by chance somewhere and were curious enough to ask about it?"

Mayuri Kurotsuchi made a guess upon hearing this, but then put the matter aside.

He has many things to do, and this vague matter cannot distract him too much.

Aizen, who had left, returned to the Fifth Division.

"team leader!"

Seeing Aizen return, Hinamori Momo ran over excitedly.

"Captain, the Commander-in-Chief is looking for you. Where have you been?"

"Oh, I went to Captain Mayuri Kurotsuchi to ask him some questions, but the Captain-Commander wants to see me. Is there something you need?"

Aizen asked gently.

When Hinamori Momo saw Aizen's smile, she lowered her head slightly, not daring to meet his gaze.

"I don't know, but Captain, you should go quickly."

"OK."

Aizen smiled and nodded, then turned and left.

Aizen turned around, his expression unchanged, but he was somewhat puzzled.

Moreover, he had a hunch that it might be related to Hueco Mundo.

When Aizen arrived, several captains were already there.

"Captain Aizen!"

The other captains raised their hands in greeting when they saw Aizen arrive.

Aizen smiled in response, his gaze sweeping over the face of Gin Ichimaru, the captain of the Third Division, before finding a seat.

The captains are Soi Fon (Second Division), Retsu Unohana (Fourth Division), Byakuya Kuchiki (Sixth Division), and Gin Ichimaru. There are now five captains here.

Footsteps sounded.

It was clear that the Captain-Commander already knew about Aizen's arrival; Aizen had just arrived when the Captain-Commander came.

The five team leaders stood up.

Captain-General Yamamoto Genryusai Shigekuni walked in.

He glanced at the five captains and spoke directly.

"Something happened in Hueco Mundo."

As soon as he spoke, Aizen's heart skipped a beat, but his expression remained unchanged as he waited for the Captain-Commander to continue.

"A huge forest suddenly appeared in Hueco Mundo, covering a vast area. Many high-ranking Hollows active in Hueco Mundo are converging on that forest. We must find out how that place appeared."

forest?

"For an investigation, it seems we don't need this many people, do we?"

Retsu Unohana looked at the Captain-Commander and asked curiously.

"It's not an investigation, it's about forming an action team to find out what happened there, and if it's some kind of trouble, to resolve it."

The captain said upon hearing this.

"So, who should go?"

Gin Ichimaru squinted as he spoke.

"Besides that forest, there's also the situation in Hueco Mundo. Not long ago, Hueco Mundo became quite unsettled. According to observations, many Hollows are approaching there. You know very well what the convergence of so many Hollows will bring."

"The captain said in a deep voice."

When Hollows fight each other, higher-level Hollows will be born.

This is a formidable opponent whose strength even the captain has to take seriously.

"Soi Fon, you'll be in charge of developing the operation plan. Share the intelligence with them."

After giving the order, the commander-in-chief left immediately.

Soi Fon, looking like a young girl, stood up and began to recount the situation with a cold expression.
