Old Monsters.

Retsu Unohana was thoroughly impressed by Keiko's work.

Keiko was punctual, thorough, and extremely skilled making a name for himself quickly throughout the soul society. He even insisted on staying outside members without taking anyone's seat and work as a regular member thus earning praise from everyone who would have lost their seat because of him. Retsu being one of the oldest members within the captain squad and also being the most trusted by the captain-commander Yamamoto knew the truth about Keiko and his power thus never interfered with anything but acted as an overseer to look into Keiko's activities.

Keiko in the meantime started trying to create new Kidos for himself. He was very bored in his wait for Ichigo and his friends. Aizen had visited division 4 using his injured squad members as an excuse and tried to talk to him about various things. Keiko knowing his intension just gave Aizen a sweet smile and then ignored him completely to not let his actions seem weird he did the same thing with every other captain too other then Unohana and Yamamoto.

Keiko also started working on his bankai and started making a list of things he should collect before making one himself. Gunbai was a good weapon but he ever hardly ever used it in any world other than to deflect an upcoming attack thus he wanted to create a new weapon for himself. He had decided on creating a sword based on either a claymore blade model or a Nandao blade which he had used a lot in SAO world.

Aizen's original plan was to integrate Keiko into Division 12 which Urahara was in charge of before being outed out as a traitor in the human world. He wanted to use the same method he used with Urahara, he would first let Keiko work and develop himself before he introduces his bankai to him thus trapping him under his illusion, thus making him under his control. After Keiko had come under his control he would introduce the topic of Hollow and Shinigami power combination to Keiko and then watch him dance around his palm while he would observe all his development and progress as he did with Urahara, after realizing that he was slowly losing power from Hogyoku.

But everything went to hell on the very first step, the rumored Swordless titan outdid everyone and chose to enter division 4 and going even further by sealing his very own eyes. Aizen seeing this started forming new plan about how to get Keiko thrown out of the division on ground of not being suitable for it but then again failed when he started hearing stories from people from his division along with others about how amazing and flawless Keiko's work is, more and more rumors about his friendly behavior and work ethics started to come. Seeing this Aizen decided to visit the division 4 relief squad under the pretense of visiting his injured division members to look closely at the rumored Swordless titan and get familiar with him but then again failed as the rumored individual only smiled at him and completely ignored him. Pissed and completely angry Aizen knew this time he had bitten more than he could chew, decided to follow his second plan about looking into Urahara's Hogyoku while also starting a plan to send back this useless titan back to the royal palace to lessen the number of people who could interfere with his plan.

His plans worked like a charm, he using manipulation used Center 46 to renquilish the order against Keiko by painting Hollows as the party behind all this.

Keiko from time to time sends reports back to Ichibe and others informing them regarding the degrading conditions of the soul society and how they are becoming weak and weak by each passing year. In one of the reports he received back from Ichibe, the news of Renjiro Kimura resigning from his duties as the royal guard came, due to his extream old age and instability with the space element his body, couldn't process more Reiatsu thus making him insufficient to fight for a longer time thus this decision was taken by Ichibe being the head of the Royal guard unit meanwhile, Keiko was selected to take his as a head of a division after he completed his time in the soul society which was already approved by the Soul King.

A few months went back when the news of Hollows being the real parties being responsible for the missing Shinigami's and village residence started circulating throughout the Soul society. Soon a meeting of Gotei 13 was called in action and the verdict of freeing Keiko from his punishment was announced to the entire soul society, Many people were sad, while Aizen was happy as one can be something was finally going his way. Keiko along with his division captain was invited by the Captain-commander Yamamoto to meet him where he would be freed, official.

Yamamoto: So what do you want to do now?

Keiko smiling removed his blindfold seal and looked at Urahara: What can old monsters like us want other then somethings to play with?

Urahara: Seems like they have told you who I am huh?

Keiko laughing out loud replied: Nope, But I could smell death over you that's why I chose you.

Urahara with an ever-smiling face replied: Don't you ever feared I could kill you?

Keiko laughed more loudly and replied: You, that old bag of bones and all the other captain's combined can't even make me sweat. If you feel like I'm exaggerating asked the old man himself.

Keiko without waiting for Urahara to reply looked at Yamamoto and asked: So what do you want?

Yamamoto: You're free to go now, so leave.

Keiko: You know, old man just because I enjoyed my time here I will tell you two things, more than one of your captains has already betrayed soul society and were responsible for this whole fiasco of missing people and second, he, your greatest enemy is not dead but is accumulating his powers and if you ask me right now, he can single hand destroy the soul society completely, of course, that is after you fall which I think will happen soon. Don't worry I will kill him after soul society falls and he returns home.

Without waiting for their questions or reply, Keiko started walking away but stopped in front of the gate and said: Oh, I will be staying in soul society for some time of course, not in division 4 but just here and there. Now that I'm here I might as well enjoy myself a little bit don't you agree?
