Gotei 13 Invading Army arc (anime only)
Note: Events occurring in this arc are only in the anime and do not constitute canon material.

In the Shinigami Research and Development Institute, Akon requests a record of traffic through the Dangai from Inaba. He brings a book into the area where Akon is discussing Nanao Ise and Rangiku Matsumoto's whereabouts with Captains Hitsugaya and Kyōraku. Inaba reveals that there is no confirmation of the pair returning through the Dangai. Later, while Akon and Hiyosu are reading the message sent by Rukia, Inaba enters the room and Akon tells him that Byakuya Kuchiki and the others are about to enter the Dangai to conduct a survey. He instructs Inaba to show them the way. Before he leaves, he sees Rukia's message and the image of an unconscious Nozomi Kujō and grins.

In a room with a large number of Reigai piled up on one wall, he takes off his glasses and puts a new set of gloves and a cloak on and takes a cane with him. Immediately after, he uses his cane to move two figures with the exact same appearance of Izuru Kira and Nanao Ise away from the door. He thanks them for waiting and asks if they shall go. With his two companions, Inaba arrives at Ichigo Kurosaki's house, where Kon has been guarding Nozomi in Ichigo's body. They pursue the girl when she escapes out the window and Inaba injures her gut when he catches up with her, requesting that his allies kill Kon to finish the job. However, Uryū Ishida shows up at the scene.

Inaba evades Uryū's attacks and defeats the Quincy by using his Shikai. Turning his attention back to Kon, he realizes that Uryū is still alive and prepares to kill him. However, Orihime Inoue shields him and he is attacked by Yasutora Sado, whom he quickly defeats. Ichigo Kurosaki then arrives and fights Inaba until the Gotei 13 arrive. Inaba decides to retreat via a Senkaimon. When he returns to his lair, he announces that he will retrieve Nozomi via the use of his invading army.

The next day, Inaba once again addresses the Reigai, outlining their plans. Captain Hitsugaya asks him what their next move is, to which he states that they must formulate a new plan before the Gotei 13 attempts to reform and return to Soul Society. He also explains that the Dangai has henceforth been sealed off, rendering communications impossible. Nanao Ise asks him what they shall do with the Captain-Commander, to which he states that he has something special in store for him.

As Inaba leaves their presence, he tells them that their desires will become revealed once Nozomi Kujō is within their possession. Later, Inaba is walking through a dimly lit corridor, in a structure similar to that of a prison. He comes across a specific cell, and opens it up, approaching the green-haired man imprisoned within it. As he rests his lamp gently on the side table, he grasps the man's head, telling him that it is useless to run from him. He then laughs wildly.

He appears before Retsu Unohana and her lieutenant, eavesdropping on their conversation for several moments, before she calls out to him. Kageroza applauds Unohana's deductive reasoning, admitting that her visit to the Daireishōkairo was unprecedented. Isane Kotetsu charges at him, but he disappears from that spot, appearing behind Unohana. Kageroza then confirms to the captain that his abilities came about due to his Dangai. She questions why he separated the Soul Society from the planes of existence, to which Kageroza states that they will understand his motives in due time. As he senses the presence of the captains entering the Dangai, Unohana questions whether his plans will be destroyed due to their intervention. However, Kageroza asks her whether she thought he would sit idly and allow them to enter. As Isane senses the captains successfully entering Soul Society, she notes the absence of Captain Komamura, to which Kageroza comments that his technology is still incomplete as of this stage. He moves forwards, prompting Isane to release a Shakkahō spell at him. Kageroza's voice echoes, commenting that she doesn't need to rush, as they pursue him.

Kageroza appears inside the underground storage chamber, flanked by the two Shinigami. Unohana tells him to stop this madness, as his plans will become fleeting, claiming that the death of the Captain-Commander is impossible. Inaba is told by her that he has underestimated the originals' strength, to which he refutes this. He claims that he merely cannot understand their objectives, primarily due to the fact that the affairs of others didn't interest him. Inaba asks whether the same could be said of her, prompting Unohana to ask what he means. He tells her that she will understand it in time, as Isane raises her sword against her.

Kageroza comments that he would not have dreamed of facing off against a captain of her stature without proper planning. He explains to her that various Shinigami have been entering and leaving through the Senkaimon in Soul Society, stating that he modified it to allow for his plans to transpire. He explains further, claiming that he took Reishi samples from each Shinigami who entered the Senkaimon, thus creating Mod Souls identical in respect to their original counterparts.He states that that is how he created the Reigai invasion force, as Inaba asks whether Unohana is able to understand. The blast door opens, revealing a Reigai counterpart of herself, as Kageroza claims that he has already sampled her Reishi, all thanks to Lieutenant Kotetsu. Unohana turns to face him, as Kageroza Inaba asks tauntingly what her next move is.
