"Sixty years ago, when I was the captain of the fifth division, Sosuke Aizen was my adjutant and held the position of deputy captain."

"But Aizen has always been elusive to me, so I am very wary and can always keep a distance from him."

Having said this, Hirako Mako smiled self-deprecatingly, and then shook his head. Looking at his expression, you could tell that he regretted it very much.

After a pause, Hirako Mako spoke again: "Although I was deliberately wary of my adjutant, I didn't expect that I ended up falling into his trap and became his stone test subject."

Hearing this, Kirito raised doubts again: "Could the test subject be talking about the existence of the mask?"

The one thing that he and Mako Hirako have in common is that they all have masks. Kirito can feel that the test subject in Mako Hirako's mouth refers to something like a mask that shouldn't exist.

"That's right, we fell into his scheme and became Masks, making it impossible to stay in Soul Society."

Sure enough, as Kirito thought, it was exactly this reason, and then he asked: "Then what happened specifically?"

Hirako Mako replied: "We were also poisoned, and thus the power of the void was invaded into the body. This was all designed by Sosuke Aizen."

Speaking of this, Hirako Mako once again remembered the scene 60 years ago. It all started with the case of the missing soul in Rukongai.

Back then, in Rukongai, a large number of souls disappeared in a short period of time, even involving the Seireitei.

At first, Seireitei didn't pay much attention to it, so they sent some ordinary Shinigami there, thinking that the matter could be solved.

But unexpectedly, not only was the cause of the missing soul case not found out, but not even one of the Shinigami who went on the mission came back alive.

This immediately attracted the attention of the senior officials in Seireitei, and they sent several pairs of people to find out the truth.

But these people, like the first team, never came back, and the Shinigami who were responsible for the search in the end only brought back their Death Tyrant costumes.

Those people seemed to have disappeared out of thin air. The most important thing was that there were no traces of fighting where the Death Tyrant Suit was left.

This made the matter even more suspicious. In order to thoroughly investigate the matter, Seireitei finally decided to send a captain-level figure to solve it.

Rokukaru Kensai, who was appointed captain of the [-]th Division at that time, and Nagana Haku, the deputy captain of the [-]th Division, accepted the order.

Although both of them were very strong, because things were too weird, the two of them arrived at the outskirts of Rukongai very carefully.

There are not many people here, and a large number of souls disappeared here before, and now it is like a wilderness.

Roku Che Kensai and Kunan Bai worked together to explore everything here, but something unexpected happened to them.

In front of them, a huge Hollow appeared. It seemed to be a big Hollow at the level of Achiukas.

Under normal circumstances, Hollows only return to Soul Society after being purified by Death, otherwise they usually only exist in Hueco Mundo.

But the Daxu that appeared in front of the two people was different. It was obvious that he was not purified.

Daxu's appearance was very sudden, and as soon as he appeared, he began to attack the two of them crazily. However, both of them were very strong, so they were naturally able to dodge the attack of this Daxu.

Then they could quickly counterattack. Because there was a fierce battle here, the Seireitei also sensed it, so they sent reinforcements.

The people who came to reinforce were Hirako Mako and the others. Following the direction of the battle, the group quickly came here.

At this moment, the place where the battle took place had quieted down, and the only ones left in the place were the unconscious Rokusha Kensai and Kunan Bai.

Everyone didn't know what happened, so they immediately stepped forward to help the two people up, and then carefully watched for enemies who might come out at any time.

The enemy who could defeat Liuche Quanxi and the two of them was obviously very powerful and had to be taken seriously.

However, something they never expected happened. Rukuchukenxi and Kunanbai, who were supported by everyone, suddenly attacked them.

At this moment, the two people had masks that only Xu could have on their faces, which shocked everyone.

The mask on Liu Che Quan Xi's face was pure white, with six holes on it, and several bone-like protrusions appeared behind him.

Jiunabai's mask was like an insect, with two tentacles, and his eyes were like two black holes, staring coldly at everyone.

Although they didn't know exactly what happened, others were helpless about the two people in front of them who were obviously in trouble.

After all, they have been friends for many years, so how could they really do anything to them, so they had to use Binding Dao to imprison them both.

However, although they were imprisoned for a while, the strength of the two of them was no different from that of Daxu, and they directly broke through the binding path they set.

Then just when they were about to continue to imprison the two of them, an accident happened again. Three people walked out from behind them.

The three of them launched a sneak attack from behind and instantly seriously injured all the people who came to support them, causing them to lose their combat effectiveness.

Then the three people revealed their faces under the moonlight. It was Sosuke Aizen, the deputy captain of the fifth division at the time, Ichimaru Gin, the third seat of the fifth division at the time, and Tosen, the third seat of the ninth division. want.

No one could have imagined that the three of them were so powerful. Even in a sneak attack, it was not easy to hit all the captains and vice-captains.

Moreover, there was obviously some kind of medicine on the knives of the three of them, which caused the people who were hit to fall to the ground, unable to struggle.

Not only were they physically exhausted, but their spirits also seemed to have been hit hard at this moment.

Afterwards, Hirako Mako and the others realized that from that time on, the power of emptiness already existed in their bodies, and it began to devour them directly.

Without any help, everyone was hit by Aizen's sneak attack, and one after another, they all wanted to be like Rukuka Kensai and Kunan Haku.

Masks appeared on their faces, and they all lost the ability to control themselves.

Even though Hirako Mako was very strong and could persist for a long time, he was ultimately unable to defeat this power and eventually faded away.

They were Aizen's experimental subjects, but they were supposed to be wiped out but they encountered a turning point because Urahara Kisuke appeared.
