I'm in Bleach, starting with Unlimited Blade Works.

It has to be said that Shiba Isshin is truly bursting with self-confidence.

Reikai Isshin inherited Shiba Isshin's strength and memories. In Shiba Isshin's own perception, only Captain-Commander Yamamoto and Captain Erin were stronger than him in the entire Gotei 13.

Kyoraku Shunsui and Ukitake Jushiro were similar in appearance.

Retsu Unohana is the captain of the healing squad, and is not known for her strength.

Other captains like Byakuya Kuchiki, Gin Ichimaru, Sosuke Aizen, Soi Fon, Mayuri Kurotsuchi, Kaname Tosen, and Sajin Komamura are all his juniors.

However, after fighting Kisuke Urahara, Isshin Reikai realized just how unreliable his original body's memories were.

Even after achieving Bankai, he couldn't even force Kisuke Urahara to unleash his own Bankai before being defeated by Urahara using Shikai, Kido, and some inexplicable items.

Seeing Shiba Isshin lying on the ground, Urahara Kisuke walked slowly towards him through the flames, pressed down his white and green striped hat with his left hand, and squatted down in front of Shiba Isshin with a solemn expression.

"How was it, Urahara?"

"Did you find anything?"

As Tessai's tall and muscular figure approached, Yoruichi Shihouin, in the form of a black cat, perched on Tessai's shoulder and asked Urahara a question.

"Yes, I've found something."

"Moreover, it's a major discovery!"

Kisuke Urahara tapped the hilt of his Zanpakuto against Isshin Shiba's forehead, and red spiritual pressure erupted from the hilt of Urahara's Zanpakuto.

"Boom..."

Under the pressure of Kisuke Urahara's spiritual pressure, the unconscious Reikai opened his mouth wide, and a brown pill popped out of Reikai Isshin's mouth.

Kisuke Urahara caught the brown pill, but before he could examine it closely, the brown pill instantly turned into blue spiritual particles and dissipated.

"This...this is the Soul-Saving Pill?"

The moment Yoruichi saw the brown pill, she knew exactly what it was without Kisuke Urahara needing to tell her.

"Ah."

Kisuke Urahara closed his eyes slightly and said in a low voice, "This is a Soul-Soul Pill, but this is not a Soul-Soul Pill."

Tessai listened to the conversation between Kisuke Urahara and Yoruichi Shihouin without changing his expression.

He couldn't understand any of these things.

Woriya Tessai is a rather simple person.

He devoted most of his energy to the cultivation of the Demonic Path; otherwise, Tessai Tsukabishi would not have become the Great Demonic Master of the Seireitei Demonic Path Clan.

Therefore, after being rescued from Soul Society by Yoruichi Shihouin, Tessai Tsukabishi followed Kisuke Urahara and provided him with assistance in Kido.

Kisuke Urahara seemed to realize that Tessai Tsukabishi was unfamiliar with the Soul-Soul Pill, and immediately explained, "The so-called 'Soul-Soul Pill' is a byproduct of a certain research project in Seireitei."

The 12th Division of the Gotei 13 is a technology development bureau that integrates countless scientific research projects within the Seireitei, including research conducted by most of the researchers over the past million years.

Kisuke Urahara was the former captain of the 12th Division. Given his personality, it was natural for him to look through the research materials that pleased him.

Coincidentally, the "Gi-soul pill" was originally a product of the previous captain of the 12th Division, Kiryu Hikifune, researching "temporary souls".

Even when Kisuke Urahara left the 12th Division, he took with him the first Gintamaru he had created.

"Several hundred years ago, Captain Kiryu Hikifune of the 12th Division created 'temporary souls'. After that, Captain Kiryu Hikifune devoted himself to the method of integrating 'temporary souls' into Shinigami themselves, which greatly increased the Shinigami's spiritual pressure."

"However, although Captain Kiryu Hikifune abandoned the research on 'temporary souls', some of the researchers who followed Captain Kiryu Hikifune in researching 'temporary souls' did not give up on this research."

Chapter 250 Yushima Ouko

"I have seen the experimental records of the Twelfth Division."

"At that time, a researcher named Yujima Osh from the 12th Division developed the artificial soul 'modified soul' based on the 'temporary soul'."

At this point, even Kisuke Urahara had to express his admiration for the researcher named Yujima Oshu.

The "temporary soul" is an artificial soul that exists for a very short time. If it is not used during its short existence, the "temporary soul" will dissipate and return to the state of spirit particles.

"Soul modification," on the other hand, is a kind of artificial soul that can exist for a long time and is no different from a real soul.

By making "Modified Souls" into "Righteous Soul Pills", "Modified Souls" can be preserved permanently.

After creating the "modified soul," Shima Osh submitted a research application to the Seireitei—Project Soul Vanguard!

The so-called "Soul Vanguard" project uses the spiritual pressure of the powerful captains in Seireitei as materials to "modify souls" and create "modified souls" that possess the captains' memories.

Then, using the spiritual pressure of the captains, the corresponding "spirit remains" are created.

When the corresponding "modified soul" is placed into the corresponding "spirit remains", these "spirit remains" will all become super weapons with the memories and strength of the captains.

It must be said that if this research were permitted, the strength of the Seireitei would almost double.

However, this research was ultimately rejected by the Central 46th Bureau.

Indeed, the "Soul Vanguard" project can significantly boost the strength of the Gotei 13.

However, this plan also presents a potential problem.

That is, if these "soul vanguard" who possess the memories and strength of the captains were to rebel against Seireitei or secretly replace some of the captains, how would everyone know?

Therefore, the Central 46 Bureau rejected Yujima Oxus's proposal, defined "soul modification" as a prohibited research matter, and even arrested Yujima Oxus.

Unfortunately, when the Central 46 went to capture Yushima Osh, they did not find him in the 12th Division. They simply sealed away all the research equipment and data related to "soul modification".

After listening to Urahara Kisuke's explanation, Tessai Kōbishiki remained expressionless.

In his view, temporary souls and modified souls were irrelevant to him.

Since being convicted by the Central 46 for using forbidden techniques and then rescued by Yoruichi Shihouin, Tessai Tsukabishi has made his own decision.

For the rest of his life, Tessai Tsukabishi served as an assistant to Kisuke Urahara and Yoruichi Shihouin, obeying their orders.

Compared to the Central Chamber 46 of Seireitei's ruthless killing of all the victims, including Shinji Hirako, Kisuke Urahara was willing to expose his research on Hollowfication of Shinigami in order to save Shinji Hirako and the others. Yoruichi Shihouin's willingness to be wanted by Seireitei in order to rescue Kisuke Urahara and herself from Seireitei was more likely to gain Tessai Tsukabishi's approval.

After all, he was a powerful demon master who used forbidden time-space techniques to save his deputy demon master, as well as Hirako Shinji and others!

Kisuke Urahara was naturally aware that Tessai Kōbō wouldn't care about what he was saying.

However, there are many things that don't mean he doesn't need to say just because others don't care.

You treat me with sincerity, and I will repay you with a song!

Although Tessai Tsukabishi followed Kisuke Urahara and did things like being a butler, Kisuke Urahara didn't really consider Tessai Tsukabishi his butler.

Rather, it would be more accurate to say that someone as complex as Kisuke Urahara admires Tessai Tsukabishi the most—a "good person" with his own independent will.

Decades ago, Hirako Shinji and others were used as subjects in Aizen Sousuke's Hollowfication experiments. The spiritual pressure of Hollows was injected into Hirako Shinji and the others, ultimately causing them to become Hollowfied.

At that time, if Tessai hadn't resolutely decided to defy the Seireitei's prohibition and use the Time-Space Kido, Kisuke Urahara wouldn't have been able to make the decision to expose his crime of researching Hollowfication in order to save Shinji Hirako and the others.

"So, Urahara, you suspect that these spirit remains are related to Yujima Oshu, who has already disappeared?"

"I don't know, but it's most likely that guy did it."

Kisuke Urahara frowned as he watched Isshin Shiba's spirit begin to dissipate into spiritual particles.

"I never expected that, besides Aizen, whom we have already discovered, there would be someone else in Seireitei who is hiding so deeply."

"If they hadn't come to us, no one would have thought that this experiment, which had been banned by the Central Bureau of 46, was still being researched by someone."

"And, considerable results have already been achieved."

"Judging from the strength displayed by this spirit body, it is probably no weaker than the real Captain Shiba."

"According to this guy, it was Yoruichi who entered the Dangai and was discovered, so in order to eliminate the threat, we need to kill Yoruichi and everyone behind her who can open the Dangai Gate..."

"In other words, this guy is very likely hiding in the broken boundary."

"Even if it's not hidden in the Broken Realm, there's probably something very important to this guy inside the Broken Realm."

"Therefore, they closely monitor anyone who can freely enter the Broken Boundary to prevent the secrets within the Broken Boundary from being discovered."

"Urahara, shall we go to the Dankai to investigate?"

"it's useless."

After listening to Yoruichi Shihouin's question, Kisuke Urahara sighed and shook his head.

"Yoruichi, we are still just wanted criminals in Seireitei. As long as we appear in the Dangai, the guy who monitors the Dangai can directly expose our existence to Seireitei."

"At that time, in order to prevent us from doing anything that would harm the Seireitei, the Seireitei will probably send several powerful captains to expel us from the Dangai."

Yoruichi Shihouin remained silent.

Yes, all three of them are still wanted criminals in Seireitei.

Moreover, how can they guarantee how many of the current Seireitei members are genuine captains, and how many are imposters disguised as spirits?

However, the good news is that, judging from the fact that the spirit body is focused on tracking Yoruichi to the human world, the researcher hidden behind the scenes, who is suspected to be Oshima, has nothing to do with Aizen Sousuke.

After extinguishing the surrounding flames and feeling that the area would no longer attract attention, Tetsuzai with Rinnegan dispelled the barrier.

However, after the barrier was lifted, Urahara Kisuke and the other two were taken aback and turned to look in another direction of Karakura Town.

Although there was a barrier there, its main purpose was to prevent ordinary people from entering the abandoned warehouse.

The spiritual pressure released by "Erin" during its battle with the Visoreds was instantly detected by Urahara Kisuke and his companions after Tessai Kōbō dispelled the barrier.

"Oh no, this spiritual pressure... it's Aizen!"

"Hirako and the others are in danger!"

"Yoruichi, Mr. Tessai, let's go!"

"Ah."

Unable to clean up the damage caused by the battle with Rei-kai Isshin, Urahara Kisuke, Tessai Tsukabishi, and Yoruichi Shihōin quickly rushed towards the location of the Visoreds.

……

"boom!"

Hiyori Sarugaki was shot down from the sky, crashing into the ground and creating a deep crater. Her mask shattered, and she lost the ability to fight.

"Hiyori!"

Seeing Hiyori severely injured from the highest point in the sky, Kunan Shiro immediately transformed into a streak of light and kicked at "Ayrin" in the air.

"Ku-Nan-Baek, Super Super Flying Kick!"
