"Four captains?" Byakuya listened to Yamamoto and couldn't help but fell into deep thought.
What kind of mission needs to be carried out by four captains of the Soul Society? Moreover, it had Zaraki of the battle squad, as well as his sensei and Unohana of the medical squad.
"Yes, that's right, and you can take your vice-captains to carry out the mission with you." Yamamoto said slowly.
"What's the mission? You'd better tell me that first, old man." Zaraki held Zanpakuto a little impatiently.
"You should know that the war is about to begin, and the preparations for the world of living have been completed. Your mission this time is to go to Hueco Mundo and help Kurosaki Ichigo and his team to rescue Inoue Orihime." Yamamoto said and officially issued the mission.
"Captain, what about Aizen and the others in the world of living?"
"Don't worry, we have completed the preparations for the world of living. This time I will personally take action and meet this traitor. All you have to do is to complete the mission in Hueco Mundo as soon as possible."
"Yes!"
"You guys go to the Technological Development Department later. Captain Kyo and Captain Unohana will go there directly to meet up with you guys. Then Captain Kurotsuchi will help you enter Hueco Mundo." Yamamoto continued.
…
In the Fourth Division.
Captain Unohana was still thinking about the words Yamamoto said.
She was summoned by Yamamoto alone.
In addition to following Mazuru, Byakuya and Zaraki to Hueco Mundo to perform rescue mission, she had another task, which was to get Ichigo and bring him to the world of living from Hueco Mundo.
Considering that the situation of Hueco Mundo was unknown, Ichigo and his friends might be injured, so she was asked to go to Hueco Mundo with her vice-captain to carry out the mission.
Of course, the most important thing was to help Ichigo return to the world of living, and be able to have enough strength to participate in the battle.
Though they were not sure when Aizen would launch a decisive attack, but they were sure that the Aizen's goal was the heavy spirit land which was Karakura Town in the world of living.
After discussing with Kisuke, they decided to build a town in Soul Society that was identical to Karakura Town, and then replace Karakura Town as a whole with the one in Soul Society through a four-pillar barrier.
However, since the Soul Society was not suitable for human beings to live-in for a long time, in order not to cause unnecessary troubles, it was necessary to put people in Karakura Town into a comatose-state, and then complete the transfer.
On the other hand, Aizen had been in Soul Society for so many years, plus his Zanpakuto's ability was too troublesome, almost all the powerful shinigami were affected by Aizen's Kyōka Suigetsu, and the rest who were unaffected were basically all shinigami who were too weak to play any role in this battle, but Ichigo had made great progress in his strength now.
Although it could not be said that he could face an enemy like Aizen head-on, but Ichigo who had never seen Aizen's Kyōka Suigetsu, and had not been affected by its Complete Hypnosis, was an indispensable asset for the shinigami side to defeat Aizen, which was why Unohana was ordered to bring back Ichigo.
Just like in Soul Society, what if Aizen and his men were picked up by Hueco Mundo's arrancar at the most critical moment using a Negación, it would be a huge blow for shinigami.
In order to prevent such a thing from happening again, Hueco Mundo needed to be controlled in advance and prevent Aizen from escaping again.
Hueco Mundo's forces had to be wiped out.
Zaraki and Byakuya, as two powerful captains, naturally had to take on this task.
Needless to say, Captain Unohana would be present to rescue and treat in time.
Originally, the last candidate should have been Mayuri, the captain of the Twelfth Division.
As an expert in technical field, he could help everyone go to Hueco Mundo, and could also open the passage in Hueco Mundo to travel back to the world of living, but Mazuru 'somehow guessed' Yamamoto's choice and before he gave the order, he found Yamamoto first.
Orihime was taken away by an arrancar when he was stationed in the world of living.
He had a responsibility.
If that arrancar could have been stopped at that time, Ichigo would not have to go on an adventure in Hueco Mundo, so this time, he had to make up for that mistake and help Ichigo rescue Orihime as well as help him return to the world of living.
After hearing everything, Yamamoto was finally convinced.
After all, Mayuri's combat effectiveness was really not much.
It was really unnecessary to bring a captain just to open the passage.
Instead of sending him to Hueco Mundo for rescue, it was better to let him stay in Soul Society and continue to complete the follow-up battle preparations.
Mazuru's combat strength was extremely good, and sending him to Hueco Mundo might led to saving Orihime quicker.
At that time, they only need to go to a specific place, let Mayuri on the other end open the passage, and welcome them back.
But for some reason, Unohana sensed something unusual in Mazuru's volunteering this time.
"What the hell are you thinking?"
She found that she couldn't see through Mazuru's thoughts.
…
In the streets of Seireitei, Mazuru once again took a walk with Nanao.
"Nanao, I'm probably going to be away for a while."
"Is there any mission?" Nanao turned her head and glanced at Mazuru.
Then without waiting for Mazuru's response, she said to Mazuru, "Go early and come back early. Also, be careful."
Mazuru was planning to say something more, but after hearing this, he could only give a soft "hmm".
After parting with Nanao, Mazuru went to the Second Division and the Tenth Division successively.
In short, he said goodbye to some girls who had a close relationship with him.
(T.L Note: Toshiro was also in Tenth Division :'))
If before that, they didn't know Mazuru was going to perform a mission, but after Mazuru had gone to bid goodbye specifically, they all knew that he was about go and perform a special mission.
There were no problems, their words were similar, go early and return early, pay attention to safety and so on.
After procrastinating for a long time, at the last moment, Mazuru slowly went to the Twelfth Division.
Byakuya, Zaraki, and Unohana were already waiting there. Except that Byakuya didn't bring an adjutant, both Zaraki and Unohana had a helper.
Zaraki took Yachiru and the one that Unohana took was not her vice-captain Isane but Hanataro.
Although seemingly weak in character, Hanataro's Zanpakuto was a genuine medical-department Zanpakuto with good abilities.
"You came too slowly! You actually let four captain wait for you for so long!"
After seeing Mazuru, Mayuri's voice was not very friendly, he still remembered that Mazuru beat him.
