Bleach: No cheat codes, he joined Aizen's side.

Chapter 149, Section 147: The Traveling Frog and Aizen's Ambition
Life after returning to Soul Society was incredibly boring for Shuichi Higashino.

Because most of the Grim Reapers he once knew had died for various reasons during the more than ten years he had been gone.

The rest either defected to the real world, or Higashino Shuichi couldn't openly interact with them.

Otherwise, it would inevitably incur the displeasure of Tsunayoshiro Shinbara.

Therefore, for Shuichi Higashino, checking on the "travel frog" he named Takuya Kabuto, which he left behind in the human world before returning to Soul Society, became a daily must-do for him, whenever he had free time.

Although Kabuto Takuya appears somewhat dull-witted in many ways when not under Higashino Shuichi's direct control due to the limitations of his imagination in creating fiction, he has indeed been steadfastly fulfilling the task set for him by Higashino Shuichi—to find other Quincy in the real world, preferably pure-blooded Quincy families with the surnames Kurosaki or Ishida, and to learn the techniques for using Quincy abilities from them.

On the first day after Higashino Shuichi left, the weather was sunny. Kabuto Takuya left the territory of Shin-Osaka Prefecture, wanting to find his Quincy companions, but he got lost and lost his way. He returned to Osaka Prefecture at night.

The day after Higashino Shuichi left, in the light rain, Kabuto Takuya embarked on a new journey to find the Quincy, making great strides along the way! But in the evening, he found that he seemed to have returned to Osaka Prefecture;
On the third day, it was cloudy. Kabuto Takuya wanted to leave by car, but was told that he needed to pay a toll. Kabuto Takuya didn't have one, but he knew that he would definitely get lost if he walked, so he came up with a plan and successfully got the driver to agree to take him to the next big city.

On the fifth day, the sky cleared. After two days of travel, Takuya Kabuto finally arrived in the city called Tokyo Prefecture. After retrieving the samurai sword that Shuichi Higashino had left him from the car owner's neck, Takuya Kabuto watched the car owner leave, overjoyed and weeping. It seemed he had done a good deed.
On the sixth day, the sky was clear, but Takuya Kabuto's heart was filled with gloom because he had been arrested. He didn't know why, but those human police officers arrested him without any explanation. The car owner from yesterday was also present when he was arrested. Seeing the indignant expression on the car owner's face, Takuya Kabuto knew that the man was also dissatisfied with his unfair treatment.

On the seventh day, it was cloudy again. Kabuto Takuya escaped from prison. Although he had not learned the Quincy's abilities, the power of the Holy Script was ingrained in his bones. Although Kabuto Takuya's development of the Holy Script was limited because he had not mastered the Quincy's abilities, he could still manage to conjure up a key to the prison gate.

On the eighth day, Kabuto Takuya was arrested again. He didn't understand why the human police were arresting him again when he hadn't done anything yet, he was just walking normally on the street, trying to see if he could find a Quincy.
On the thirteenth day, due to the increased guard by the human police, Kabuto Takuya waited until the human world was thrown into chaos by the appearance of a Hollow before he was able to find an opportunity to escape. Fortunately, the Hollow that suddenly attacked was dealt with by two Quincy. With the advantage of being a pure-blooded Quincy himself, Kabuto Takuya quickly gained the approval of these two Quincy and they personally agreed to teach him Quincy skills. Thus, Kabuto Takuya also learned the names of these two Quincy, Kurosaki Yuki and his wife, Kurosaki Mai.

On the twenty-fourth day, Kabuto Takuya temporarily settled in Tokyo Prefecture with Kurosaki Yuki and Kurosaki Mai, and continued to receive Quincy training from them. Perhaps because he was created by Higashino Shuichi using Yhwach's body as a template, and because he drank the core blood from Yhwach's heart and formed Quincy power with the Soul King's eyes, Kabuto Takuya had a talent for learning Quincy abilities far exceeding that of ordinary Quincy.

In just over ten days, Kabuto Takuya mastered the techniques for using most Quincy abilities, and could even switch quickly and skillfully between the still blood form and the moving blood form. Even the Quincy ultimate ability that Kurosaki Yuki called the most difficult to learn and master, the Chaotic Puppet, Kabuto Takuya mastered completely in just three days. Today, Kurosaki Yuki praised Kabuto Takuya as a Quincy genius who appears once in a millennium, with the potential to become the new Quincy King. However, Kabuto Takuya always felt that Kurosaki Yuki's wife, Kurosaki Mai, looked at him with a strange look in her eyes, as if she was pitying him?
On the twenty-ninth day, Takuya Kabuto told Mai Kurosaki that he knew Satomi Nagasawa, which surprised Mai Kurosaki greatly, and the relationship between the three of them deepened once again.
On the thirty-seventh day, just as Kabuto Takuya got up and was preparing to further hone his Quincy abilities, an Arrancar with eight tubes inserted into its back and an oxygen mask on the lower half of its face appeared in front of Kurosaki Yuki and Kurosaki Mai.

At the same time, Higashino Shuichi, who had just woken up in Soul Society, immediately took over Kabuto Takuya's consciousness.

This is very abnormal. At this time, Aizen's previous Hollowfication experiments with the captains were not ideal. They could only help captains of the same caliber as Shuichi Higashino to raise their spiritual pressure limits to a certain extent, but they could not achieve the effect of breaking the shackles of the Shinigami that he had envisioned. Therefore, Aizen's focus was still on how to fuse the power of Shinigami and Hollows. At this time, Aizen's control over Hueco Mundo was absolute.

Higashino Shuichi can say without reservation that during this period, and even up to the beginning of the story, the movement of every Arrancar in Hueco Mundo basically required Aizen's approval.

Therefore, the fact that this Arrancar has come to the present world can only mean one thing: Aizen has taken the future that Higashino Shuichi described seriously and has begun to consciously adjust his strategy against the Quincy.

Ha, a man who says one thing but does another.

Higashino Shuichi recalled the disdainful look Aizen had given Yhwach in front of him that day.

However, on the other hand, Shuichi Higashino did have some feelings for the Quincy pair of Yuki and Mai Kurosaki.

It wasn't just because these two were related to Nagasawa Satomi, nor just because they shared the surname Kurosaki, but also because of their meticulous guidance and their willingness to endure the trouble that Higashino Shuichi's creation, the dim-witted Kabuto Takuya, had caused them. This allowed Kabuto Takuya to master the abilities of traditional Quincy in such a short time.

Therefore, it was impossible for Shuichi Higashino to just stand by and watch these two get killed by that Arrancar.

Yes, although Kurosaki Yuki is a pure-blooded Quincy, there are still differences in strength among Quincy. Due to Yhwach's slumber, the Quincy who are still alive in the world have long lost their former glory. Apart from the future Ishida family, the father-son duo Ishida Ryūgen and Ishida Uryu, most of the Quincy in the world are probably not as strong as an ordinary lieutenant of the Gotei 13.

In Higashino Hideichi's view, Kurosaki Yuki is a prime example of someone who has plenty of theoretical knowledge but lacks practical skills.

No wonder he and Mai Kurosaki chose to leave Osaka Prefecture as soon as they discovered that Shuichi Higashino and his group had escaped to their vicinity.

However, since Higashino Shuichi's Shinigami body is in Soul Society, it is impossible for him to come to the human world to provide assistance. Furthermore, even if he could, Higashino Shuichi's Shinigami body would have no reason to do so.

While the body of Kabuto Takuya, which Higashino Shuichi is currently controlling, possesses practical combat abilities, ...
Higashino glanced at the Arrancar not far away, who was beating up the Kurosaki couple, and decided to let it go.

There is one thing that a Quincy of Kurosaki Yuki's level cannot see: the Quincy body that Higashino Shuichi created has a very limited number of spiritual particles that he can control.

This is also the biggest difference between Higashino Shuichi's Quincy power and that of ordinary Quincy.

The core reason why he was able to become the first Shinigami to undergo Quincy transformation in his Shinigami body lies in the special nature of the power carried by his Soul King eyes.

Otherwise, it would be impossible for a normal Shinigami, without a human body or soul, to possess the power of a Quincy.

However, this creates an absurd reality that could only happen to Shuichi Higashino.

That is, his Quincy power was suppressed and restricted by his own spiritual power.

It sounds ridiculous that two completely different, incompatible abilities are actually constrained by the other because of the peculiar ability to fabricate reality.

Furthermore, due to the incompatibility of the two abilities, even if Higashino Shuichi wanted to extract a tiny bit of his spiritual pressure and allocate it to the Quincy's power, he couldn't do it.

As a result, Kabuto Takuya's current body is entirely supported by the Spirit King's eyes on his body.

However, the limit of these eyes is that they can withstand the pressure of the Shinigami power on the body of Shuichi Higashino and maintain the power of the Quincy. They can only provide more Quincy power and more spiritual power to control the spirit particles.

Simple, just give me the subsidy!

If Higashino Shuichi is not mistaken, as long as he stuffs more Soul King body fragments into the Quincy body he has created, he can use more and maintain his Quincy abilities for longer.

But where can Higashino Shuichi find the fragments of the Spirit King's body now?

The Soul King fragments that Higashino Shuichi had previously provided to Mayuri Kurotsuchi had long been squandered by Mayuri because of the ten years that Higashino Shuichi had been missing. Higashino Shuichi didn't even need to ask Mayuri Kurotsuchi; he only needed to see that Mayuri Kurotsuchi never mentioned the Soul King fragments in their conversations to know that Mayuri Kurotsuchi was definitely hiding something.

Therefore, while Higashino Shuichi might have a chance to defeat that Arrancar now, it's definitely not high compared to other options.
Higashino narrowed his eyes. Not far away, the Arrancar was still toying with Kurosaki Yuki and his wife. Based on his observation and understanding of Arrancar, the Arrancar clearly had many opportunities to kill Kurosaki Yuki and his wife, but it gave them up every time.

Why is that?
Do you need to ask?
A knowing smile appeared on Higashino Shuichi's lips. He then crouched down, extending his right hand forward, palm facing upward. If there was any flaw in his Sacred Script Ability I, Higashino Shuichi felt it was this fictional content—something that must exist in the future.

Because, theoretically, a man with Yhwach's body could exist in the future, Higashino Shuichi was able to create Kabuto Takuya using Yhwach's body as a template.
Therefore, this ability is useless to more than 99% of people in the world.

If they cannot imagine what the future will look like, they cannot create a future reality.

However, for Shuichi Higashino, this flaw can be completely ignored.

Is there anyone more certain than him about what will emerge in this world in the future?
"Take off, Woodow drone swarm!"

In an instant, one after another, nightingale-sized drones appeared in Higashino Shuichi's palm and were quickly launched away.

In less than three minutes, the 3D real-time images created by these drone swarms presented everything within a radius of several kilometers to Higashino Hideo.

And among them was that man, Aizen Sousuke.

"So, these little things that suddenly appeared in the sky were your doing?"

Aizen Sousuke stood in mid-air, holding in his hand a wooden owl drone that was still flapping its mechanical wings.

Aizen Sousuke was somewhat surprised by Higashino Shuichi's appearance, but he also felt it was reasonable.

In contrast, he was more curious about the novel object he had never seen before in his hand, and how the strange Quincy who had found him had created this little thing out of thin air.

"Yes, Lord Aizen!"

"I'm speaking," said Higashino Shuichi with a bright, sunny smile.

"Lord Aizen? You know me?"

Upon hearing Higashino Shuichi's address, Aizen finally turned around and took another look at the young, unfamiliar Quincy before him.

She was alright looking, but she didn't appear in his memory.

Aizen considered himself to have a good memory, so it was impossible for him not to remember the Quincy in front of him.

"Last time, I briefly mentioned it to you, Lord Aizen, but you were probably so focused on the future where you would be killed that you forgot about it for a moment."

As I mentioned before, I gained some unexpected benefits in that fictional future.

Shuichi Higashino said frankly.

It wasn't that he didn't want to hide it, but rather that it was pointless. Firstly, the power of the Quincy wasn't the key to defeating Aizen, and secondly, if Higashino Shuichi wanted to fuse a new Soul King fragment into this body in the future, he might still have to rely on Aizen's Hogyoku.

Otherwise, Higashino Shuichi would have to go to Urahara Kisuke or wait for Kurotsuchi Mayuri's experiment to be completed.

For Shuichi Higashino, the former was not as good as finding Aizen, at least Aizen's desires did not conflict with Shuichi Higashino's. However, what Kisuke Urahara wanted was unknown to Shuichi Higashino until he traveled through time. To Shuichi Higashino, this was someone who was even more hidden than the obvious bosses.

The latter, however, is fraught with uncertainty; who knows when Mayuri Kurotsuchi will be able to complete his research on soul fusion?

Therefore, since I'll have to tell Aizen sooner or later, I might as well be honest now and earn a reputation for loyalty.

"I see. So this is what you gained from that fictional future? Quincy power, it suits you quite well~"

Aizen instantly understood what Higashino Shuichi meant, and his admiration for Higashino Shuichi grew even stronger.

No one can ever have too many surprises.

Watching Higashino Shuichi grow step by step under his watchful eye to the point where even he could hardly understand him, Aizen suddenly had an unrealistic idea.

In the end, will it be that Shuichi Higashino breaks free from the shackles of death before him?
Although Higashino Shuichi always said that he just wanted to keep up with his own pace, he kept trying to find ways to improve his strength.

However, Aizen Sousuke carefully recalled Higashino Shuichi's past. From the Shinigami who was not favored by him at the beginning and whose spiritual pressure limit was naturally limited to the level of an ordinary captain, Higashino Shuichi has gradually reached his current level. Isn't Higashino Shuichi breaking the shackles that bind him time and time again?

"Interesting, really very interesting."

Higashino Shuichi watched as Aizen casually tossed away the wooden Owl drone in the air not far away and muttered to himself, somewhat puzzled.

What he didn't know was that Aizen's heart was now incredibly open and excited compared to before.

In the past, he thought that there was only one decaying mountain in front of him, Yamamoto Genryusai Shigekuni. He believed that as long as he could overcome him, he would be invincible in the world. He was lonely.

But now, Yamamoto, that mountain, is practically gone. However, just after he found himself a barely passable opponent, Kisuke Urahara, his lovable subordinate, Shuichi Higashino, brought him three more pieces of good news.

One was that he was taken to the Great Spirit Book Corridor, where he learned of the existence of the Spirit King and the Zero Division;

One was that he brought back information about the future: in the near future, there would be a Quincy King named Yhwach who would plan to destroy the world for a foolish goal.
Lastly, there's Higashino Shuichi himself. Even though he still looks so weak now, he's been steadfastly moving towards himself, taking those unwavering steps. So, will there ever be a day when he can truly stand shoulder to shoulder with himself, or even surpass him?

"Haha, this world is really getting more and more interesting!"
