However, the true Gotei 13 arrives, having escaped their earlier conflict and offers to hold off the Regai while Ichigo and company carry on. As they run though, Ichigo passes out, only to wake up inside a building. Urahara regretfully informs him that in his weakened state, he is a danger to everyone and that they need to leave him behind. To be safe, Urahara binds Ichigo to the floor with a high level Bakudō spell. Left alone and with nothing to keep him in check, Ichigo's Hollow takes over and Ichigo assumes a fully hollowfied state, breaking out of his bindings and escaping into the streets. As the Hollowfied Ichigo burst on to the streets, several Shinigami are drawn to the area. As they panic after seeing Ichigo. Reigai Nanao Ise arrives and tells the Shinigami to deal with the Hollow.

However, his rampage is suddenly stopped by the arrival of the newly reformed Ōko Yushima in mod soul form.

Battle
As Yushima walks past him, Ichigo temporarily regains control, wondering who he is. He quickly loses control again and fires a cero at Yushima who stands before him. Yushima quickly dodges and Ichigo follows, firing another cero. Yushima dodges as Ichigo charges at him. In response, Yushima fires a Shitotsu Sansen, binding Ichigo to a rock. However, as Yushima begins to walk away, through sheer power, the Hollowfied Ichigo breaks through the spell and leaps into the air to attack Yushima. Yushima responds with Hadō 58. Tenran. As Ichigo is blown back, Yushima hits him with Bakudō 99 part 1 Kin, slamming him to the ground and binding him to it. Yushima prepares to finish Ichigo off but hesitates as Nozomi Kujō's feeling come to the surface for a moment. As this happens, Rukia Kuchiki charges Yushima as Renji Abarai knocks him back with his released Zanpakutō.

Arriving along with them Uryū Ishida notices that the man before them's reiatsu feels like Kagerōza Inaba's, prompting Yasutora Sado to realize that Inaba got a hold of Nozomi. Orihime Inoue becomes saddened by this as everyone readies themselves. Yushima tells the group that they must know by now that they stand no chance against him and asks what they came for. Rukia tells him that they came to save their friends. The mention of the word friends reminds Yushima of moments in his life in which he felt the loneliness of not having friends. He tells them that if their lives mean so little that they are willing to throw them away for others, they can die there then. Yushima quickly gets behind the group but Uryū fires an arrow at him. Yushima easily cuts through the arrow and Uryū explains to everyone how Yushima's Zanpakutō works. Yushima apologizes then for underestimating Uryū and says he will show them his true power. Renji attacks but is thrown back and wounded as his Zanpakuto strikes Yushima's. Sado and Rukia attack but Yushima dodges. Uryū then fires a volley of arrows at Yushima who manages to absorb and fire them back. Everyone is thrown back except Orihime, who shields herself and the bound Ichigo.

As everyone lays on the ground, wounded, Yushima reveals that this is the power of his true Zanpakutō, Sumitsukigasa. He explains that Sumitsukigasa has the power of both Inaba and Nozomi's Zanpakutō and that his Zanpakutō now has no downsides and continue to absorb and return attacks infinitely. Renji stands up and prepares to attack. Uryū tries to tell him not to but he activates his Bankai and attacks but his attack is quickly thrown back at him. Sado says that any attack they send at Yushima will be sent right back at them. Standing up, Uryū says that their only option is to mount an attack that Yushima cannot absorb. Everyone gets up and Uryū fires his Licht Regen at Yushima as Rukia fires her Tsugi no mai: Hakuren at him from the other side. Renji attacks with his Bankai but Yushima knocks it apart before appearing in front of Renji. Yushima says that he will take them all down one by one so they cannot coordinate their attacks and goes to stab Renji but Sado appears and defends Renji. Uryū yells to Rukia who then unleashes another Hakuren. However, Yushima, greatly angered, manages to knock away the attack barehanded. He then stabs through Sado's armored arm and slashes Renji's chest, cutting them both down. Uryū fires another volley at Yushima but once more it is fired right back at him. The resulting force is enough to rip the chains the bind the hollowfied Ichigo up from the ground and send him flying back. Yushima says that now that he has absorbed Nozomi, his power far surpasses everyone else's. Rukia asks if this was why Inaba was after Nozomi and Yushima says that this was the original power of his Zanpakutō but he was too weak to wield it before. Rukia asks if he plans to use this power to rule the Soul Society. Yushima laughs and says no, he plans to destroy the Soul Society. Raising his Zanpakutō, he goes to kill Rukia, but as he goes to stab her, the hollowfied Ichigo steps in and takes the attack for her.

Nozomi and Ichigo both regain momentary control and Nozomi calls out to him, causing his Hollow form to crack away, but his Shinigami powers to once again fade. He falls to the ground and Rukia asks if he is okay. Rukia tries to attack Yushima while he is distracted but Yushima dodges easily. Orihime rushes to Ichigo and Rukia tells her to take Ichigo and run. Ichigo however, says he cannot leave and tells everyone how when he touched Yushima's blade, he felt Nozomi inside. Yushima recounts to himself that his consciousness went blank for a moment and calls over to his lab for Reigai Nemu to bring him more fusion stabilizer. Overhearing this, Rukia makes note that his fusion is not permanent yet. Yushima calls out to Ichigo, saying ignoring him was a mistake and goes to finish him but all of Ichigo's friends come to his side to support him. Yushima tells them all to step aside but Uryū says they are not obedient enough to do as their enemy says. Renji says they will never hand their friend over, prompting Yushima to go into a tirade about friends, saying that they are uselessly spilling their blood for others. He then prepares an attack.
