Conspiracy Revealed: End Game

During the Ryoka Invasion Captain Sosuke Aizen is murdered and the whole of Seireitei is in utter turmoil. However, in Conspiracy Revealed: End Game the truth about Aizen is revealed. It is shown that Aizen, 3rd Division Captain Gin Ichimaru and 9th Division Captain Kaname Tōsen are traitors and have been manipulating the various people and organizations of Soul Society to attain a forbidden and powerful item. The culmination of the events that lead to this point would only be the beginning of what would eventually turn into a war to save the world.

Ichigo Kurosaki who with his companions, Orihime Inoue, Yasutora Sado, Uryū Ishida, Ganju Shiba and Yoruichi Shihōin is able to save Rukia Kuchiki a Shinigami in the Gotei 13. But the apparent murder of Captain Sosuke Aizen of the Fifth Division makes all of Soul Society suspect the Ryokas. Hoever it is later revealed that Aizen is very much alive and had faked his death but was the mastermind behind the whole affair along with his accomplices, Captain Ichimaru Gin of the 3rd Division and Kaname Tōsen of the 9th Division. It is Hitsugaya Tōshirō who suspicious of Gin all along is attacked by Momo Hinamori  lieutenant of the fifth division under Aizen believing that it was Hitsugaya who had murdered Aizen, unravels the truth.

Prelude
Tōshirō Hitsugaya and his Lieutenant Rangiku Matsumoto head towards the Central 46 Chambers and finds the area locked and barred. He breaks into the chambers but to his surprise finds the Central 46 massacred and comes to the opinion that they had been dead for quite some time. He is interrupted by the arrival of Izuru Kira the lieutenant of the 3rd Division and the two follow him out. However as they are following him Kira tells Tōshirō that he should be protecting Momo Hinamori instead as she had broken out of his barrier and had been following Tōshirō ever since. He leaves Kira to Rangiku and goes back to the Chambers searching for Momo.

Betrayal
At the same time Momo reaches the Central 46 Chambers and she too sees the horrid sight. She senses that Tōshirō had been there and Kira too. She wonders that if Tōshirō had been taken by surprise then could it have been Kira's doing. As she is lost in thought Ichimaru Gin Captain of the Third Division appears behind her and orders her to follow him. They proceed to the residential area for the Central 46 and he tells her that there was a certain someone who wished to meet her. She turns back and the person who wished to see her is none other than Sōsuke Aizen her beloved Captain whom she had believed to be dead. Momo forgives Aizen instantaneously believing that he must have some reason behind his actions. However she is betrayed once more as she stabbed by her captain Aizen whom she had admired all her life. As the two are leaving, Hitsugaya reaches the spot only to find a fatally wounded Momo. He asks Aizen why he took her life to which the latter answers that he did it out of sympathy for Momo would not have been able to live without him. An enraged Tōshirō releases his Bankai, Daiguren Hyōurinmaru and he charges towards Aizen but is wounded instead for he is caught in Aizen's Kyōka Suigetsu's Complete Hypnosis.

Conspiracy Revealed
However, Captain Retsu Unohana of the Fourth Division arrives along with her lieutenant Isane Kotetsu. She inquires about Aizen's fake death. He then tells her about his Zanpakutō's special ability, that is complete hypnosis and how anyone who sees his sword being released just once would be completely hypnotized. After he explains his Zanpakutō's abilities, he and Gin escape. Elsewhere Kaname Tōsen is seen abducting Abarai Renji and Rukia Kuchiki. As the two disappear Captain Unohana orders Isane to track the defectors and also to inform all the Captains, the Captain Commander, all other seated officers of the Gotei 13 as well as the Ryoka about the defection of Sōsuke Aizen, Ichimaru Gin and Kaname Tōsen. She then proceeds to heal Hitsugaya Tōshirō and Momo Hinamori. Isane uses Kidō to track traitors and to inform the others. The Gotei 13 is seen in a state of shock and disbelief. Elsewhere, Kaname Tōsen brings Renji and Rukia to Sōkyoku Hill where Aizen and Gin join them. Aizen orders Renji to hand over Rukia and to leave but Renji refuses and tries to fight back but is no match against the powerful foe. However just as he is about to be killed at Aizen's hands Kurosaki Ichigo saves them. The two of them then join forces to fight off Aizen. Renji uses his Shikai Special Ability, Higa Zekkō where he uses the broken segments of his Zanpakutō to surround the opponent in order to give Ichigo an opening. But this plan proves futile for Aizen is able to deflect Ichigo's sword with his finger and instead slashes him across the midriff just by flicking his finger. As Ichigo falls to the ground in a state of shock, Aizen slashes Renji. He then takes Rukia by the collar but is interrupted by Ichigo who surprises him as he is still alive. Aizen then begins to tell Ichigo how he had planned every move from the beginning for his goal, to obtain the Hogyoku with the help of which he would be able to surpass the powers of normal Shinigami by merging the thin line between that of Shinigami and Hollows. However their conversation is interrupted by Sajin Komamura captain of the 7th division who tells Aizen that he would never forgive his betrayal to Soul Society and demands an explanation from Tōsen. He proceeds to hit Aizen with his Shikai but Aizen stops it with his bare hands and gets away quickly and moves up close to him.He then tries to release his Bankai but is unable to for Komamura is caught in Aizen's hypnosis. Aizen then defeats him singlehandedly and easily using a Level 90 Kidō spell. Ichigo looks on dumbstruck, wondering about the vast difference between the power of two Captains. With Komamura out of the way Aizen continues his conversation with Ichigo and tells him that Urahara Kisuke had planted the Hogyoku inside Rukia Kuchiki in order to hide it's very existence as Rukia was inhabiting a Gigai that would ultimately reduce her to a normal human. Thus concealing the Hogyoku for ever. Just then Ichigo's comrades, Orihime Inoue, Sado Yasutora, Uryū Ishida and Ganju Shiba arrive at the scene but are rendered helpless as Ichimaru Gin releases an enormous amount of spirit power. Aizen then proceeds to extract the Hogyoku from within Rukia using an item that was made by Urahara Kisuke that could forcibly take the Hogyku from within a soul. One other way that Aizen had thought of by using the Sōkyoku on Rukia had been proved to be a failure because of Ichigo Kurosaki.

End Game
He then takes the Hogyoku out of Rukia and then orders Gin to kill her for she was of no use now. As Gin releases his Shikai Shinsou and aims for Rukia, her brother, Byakuya Kuchiki appears and saves her by shielding her against Gin's attack with himself. Aizen then steps forward to kill them but is stopped by the arrival of Jidanbō Ikkanzaka and Kūkaku Shiba. Yoruichi Shihōin and Soifon incapacitate him as Soifon holds her katana to his throat. Ichimaru Gin is captured by Rangiku Matsumoto. The Captain Commander, Genryūsai Shigekuni Yamamoto, Shunsui Kyōraku and Jūshirō Ukitake also arrive along with Chōjirō Sasakibe and Tetsuzaemon Iba.

However as the defectors are cornered Menos Grande appear and use Negaciόn to save them. They leave and the Shinigami are unable to stop them. As they leave Komamura asks Tōsen where his justice had disappeared to but Tōsen answers that the path that he walks was justice. Ukitake asks Aizen how he could stoop so low but he tells Ukitake that he was always too proud and that heaven was always empty but now he would fill the emptiness. He leaves bidding farewell to the "Ryoka-boy," Ichigo. After their departure the 4th division takes over the healing procedure for the wounded. As Byakuya lies, undergoing the treatment, he calls for Rukia and tells her that he had adopted her on behalf of his wife, whose dying wish who was for him to protect her sister, who she had abandoned when she was very young. By adopting her, as well as marrying Hisana, both of whom were from Rukongai, he had defied the rules of his family. He then made a promise to his dead parents that he would never break the laws again. Hence, when Rukia's sentence had been announced, he was not sure if he should keep his promise to his parents or the one to his wife and he apologizes to Rukia. He thanks Ichigo for opening his eyes that he should have fought the laws of Soul Society, as Ichigo would have done if he had been in Byakuya's position.

Aftermath
Aizen, Gin and Tōsen escape. Byakuya, Ichigo, Renji and Sajin Komamura are severely injured. Rukia is safe but the Hogyoku is in Aizen's hands and would be possibly dangerous for Soul Society as well as the real world. Ichigo and his companions' efforts are acknowledged by the Gotei 13.
