Back to Soul Society.
For the shinigamis of Gotei 13, not seeing someone for a few days without causing any disturbance won't arouse any suspicions. It is even more so, if the ones are Mazuru, Aizen, Kaname and Gin who are among the mainstay of Gotei 13 for the current Seireitei. No one would have thought that they had different ambitions and did so many things in Hueco Mundo.
In the Third Division, Gin was handling the team affairs, when he suddenly raised his head and glanced at Mazuru, who was slacking off beside him, and asked, "That guy is really strong, isn't he Captain?"
Mazuru knew whom Gin was talking about, so he nodded and answered, "Yes, he's really strong."
"After arrancarization, the ability of High-Speed Regeneration will disappear and the Arrancar will possess Hierro, but he not only retains the High-Speed Regeneration but the strength of his Hierro is also far beyond the ordinary Espada… I have to say, Captain Aizen has created a monster."
In the captain's room of the Third Division, the captain and vice-captain of the Third Division were blatantly discussing the matters of Hueco Mundo, calling it a bold act would be an understatement.
But for Gin and Mazuru, it was nothing more than a routine operation.
Listening to Mazuru's words, Gin squinted his eyes again and looked at Mazuru with a smile, "But if it's you captain, then you should be able to defeat him."
"Why did you think so?" Mazuru asked back, "Obviously I was the one who was more injured at the end of that battle."
"It's just a feeling." Gin responded, "However, it's still hard to imagine that such a powerful hollow is willing to submit to Captain Aizen's command without a single question or signs of disobedience."
"After all, Captain Aizen gave him that power, and..." Mazuru glanced at Gin, "Gin, you seem to be questioning Captain Aizen's charm."
"No no… how dare I." Gin shook his head.
The two continued to chat.
Gin wanted to find out some more information from Mazuru, but it was a pity that Mazuru revealed only things that Gin knew and shrugged off at the rest.
Time went by and it seems that because arrancarization's success rate was already very high, Aizen had gradually become a little bored and started to continue his previous experiments circling around shinigami's abilities.
He also thought of those captains and vice-captains who were framed by him back then.
Back then, he conducted the hollow experiment on Shinji, Kensei and planned to use them as experimental subjects.
The result of the initial experiment was very gratifying. He obtained a lot of data from that experiment, and it was these data that made him succeed in arrancarizing the hollows without spending too much extra time.
Even if the success rate of arrancarization was low at the beginning, but success is success.
Unfortunately, that night, because of Kisuke's obstruction, he failed to keep Shinji and other experimental subjects. Of course, he later put the blame on Kisuke for that incident, but Shinji and others also were rescued by Kisuke and taken to the world of living.
After all these years, are Shinji, Kensei, etc. alive?
What became of them after that hollowfication?
Aizen was curious.
As a result of his curiosity, his attention also began to shift from Hueco Mundo to the world of living, and he began to stir up things frequently in the world of living, hoping to take the opportunity to find the whereabouts of Shinji and others.
Of course, if Kisuke's whereabouts can be found, that's even better.
Unfortunately, he still couldn't find them. But now that the idea of restarting the shinigami's hollowfication experiment has been ignited, it was not so easy to suppress it.
Aizen has always acted without scruples.
He immediately experimented with the shinigamis stationed in the world of living by the Thirteenth Division.
In just a few months, several shinigami stationed in the world of living had accidents one after another.
Soon, the matter was noticed by the Soul Society.
After the Thirteenth Division discovered the matter, they immediately realized the seriousness of the matter. While continuing to send shinigamis to the world of living to maintain its safety, they handed over the report of the incident to the Tenth Division.
As a patrolling guard, the Tenth Division is not only responsible for the internal security of Seireitei, but also needs to deal with all emergencies and issue emergency intelligence and man-support.
In the captain's room of the Tenth Division, Isshin, who had just been caught by his vice-captain Rangiku, was looking through the team affairs documents, and dealt with them helplessly under Rangiku's watchful eye.
Toshiro, who has become the 3rd seat of the Tenth Division, looked at Isshin who was handling the documents, and suddenly remembered something, and reported it to Isshin, "Speaking of which, captain, here is a report that I am very concerned about."
While talking, Toshiro searched for it.
"Here it is."
Toshiro handed the report to Isshin. Isshin was not in the mood to deal with team affairs and was still lazing in his work, if not for suddenly being caught by Rangiku, he would rather not do these, but seeing that Toshiro was so serious, he could only read the report carefully.
"In a medium-sized city called Naruki, shinigami, who was in charge there two months ago, died in an accident," explained Toshiro.
"It seems that is indeed the case." Isshin rubbed his chin, thinking about it, "Is the reason of death still under investigation?"
"Now read this." Toshiro pointed to the document handed to Isshin earlier, "I just received an additional report on this incident from last month."
"The reason is still not found out, and two more died last month."
Isshin didn't know what he thought of, he suddenly straightened his body, and resolutely started leaving from here.
"Ah! Captain, where are you going?" Rangiku was startled.
"To investigate, I'll see you guys later."
As he said that, he disappeared completely from their sight. Rangiku was going to chase at first, but Toshiro not only did not chase, but also stopped her, "Don't follow captain."
Rangiku was puzzled.
"What do you mean?"
"The captain must have felt that this investigation is too dangerous, so he went alone."
"I also understand this kind of thing, so it should be more of a reason to follow him."
"That's why it's more important to stay here now." Toshiro said very seriously, "You should understand Rangiku. We can only stay here obediently and wait for him to come back. If we follow, we will only hold back captain."
Having said that all that, when she turned her head and looked at documents on the table that hadn't been dealt with at all, Rangiku always felt that Isshin felt that dealing with team affairs was too boring, so he used this as a reason to go out and fool around.
