Ichigo Kurosaki, Rukia Kuchiki & Yoruichi Shihōin vs. The Reigai

 is a fight taking place within the Reigai Uprising. It focuses upon the conflict between the three Shinigami and the Reigai army, who proceed to stop them from entering the Senkaimon and returning to the Human World.

Prologue
As Ichigo Kurosaki and Rukia Kuchiki stare despondently at the frozen image of Nozomi Kujō, Rukia asks him what their next move is. He states that they will attempt to return to the Human World, but Rukia berates him for thinking that their enemies will just sit idly and let them leave. Ichigo asks what she believes is the right course of action, but she is unable to come up with anything. However, Yoruichi Shihōin arrives at the Shinigami Research and Development Institute, as Rukia asks what had become of the Reigai. Yoruichi states that mere impostors would never get the better of her. Ichigo comments upon her superior speed.

Rukia informs Yoruichi that the Reigai have probably taken up guard outside the Senkaimon, and that getting there will be no easy feat. Yoruichi agrees, and states that their only option is to break through head-on. Both Rukia and Ichigo are surprised at this statement, as Rukia reiterates that Yoruichi had told them that the impostors have strength paralleling that of a Gotei 13 captain. However, Yoruichi states that the reason that they will be attacking head-on is due to the fact that they are impostors.

Battle
Ichigo, Yoruichi and Rukia land upon a rooftop close to the Senkaimon, their target. As Rukia and Yoruichi previously thought, the Reigai clones are standing guard over the single route to the Human World. The clone of Shūhei Hisagi notes their arrival and other clones soon arrive in the area. Yoruichi states that the clones were planning on intercepting them, but explains that they cannot hold off the Senkaimon wall for a long time, and that that is their window of opportunity to enter the Dangai. She maintains that they do not need to fight a prolonged battle and that their aim is to merely punch through their defensive wall to get to the Senkaimon.

The three of them then leap towards the courtyard being defended and Hisagi's clone alerts the others to the movements of their targets as he spins his Shikai in preparation. Tōshirō Hitsuaya's Reigai draws his blade, reminding the others that their only goal is to stop them from getting through the Senkaimon and that first, they must slow them down. Advancing forward, Ichigo engages Ikkaku Madarame's copy while Rukia blocks an attack made by the duplicate of Renji Abarai, being forced to the ground. He taunts her while he lands in front of her. Rukia moves to attack the clone of her friend when she realizes that her blade has been tangled in the chain of Reigai-Hisagi's Zanpakutō.

Still battling Reigai-Ikkaku, Ichigo calls out to her, but his opponent warns him not to be distracted as they continue to skirmish. The Reigai forces Ichigo to the ground before the Reigai copy of Tetsuzaemon Iba attacks him from behind, forcing Ichigo to quickly evade the blow using Shunpo. The Reigai's Zanpakutō ends up smashing into the grounds and it destroys much of the tiles Ichigo had previously been standing on. Ichigo then retreats to Rukia's position and, outnumbered, the friends are forced to stand to the back to back as they face down their many opponents.

Meanwhile, Yoruichi is confronted by the Reigai clone of Sajin Komamura, who charges at her and swipes his blade in her direction. Yoruichi is able to use her superior mastery of Shunpo to easily avoid the blade, landing a good distance away from the captain clone. She is soon confronted by the replica of Hitsugaya who attacks using Hyōrusenbi which the former captain is also able to avoid without much difficulty. Despite this, she is soon taken by surprise by Komamura's copy, who uses his Shikai to bring the giant sword down upon her.

However, just when she as she is about to be defeated, she is revealed to be a Portable Gigai, like those created by Kisuke Urahara. Right after Yoruichi's Gigai is popped, both Ichigo and Rukia's also pop, confusing their attackers, who pause in a startled fashion. Reigai-Renji wonders what happened before Ikkaku's clone insists that he had yet to touch them before they vanished. The captain clones also look about themselves in a confused manner, clearly fooled by the diversion as well.

From seemingly out of nowhere, Ichigo fires a Getsuga Tenshō that causes the Reigai to shield themselves as it passes them and hits the Senkaimon, destroying part of the wall protecting it. Yoruichi, Ichigo and Rukia use their distraction to race towards the gate unhindered. Rukia admonishes Ichigo for letting his Gigai burst first because then she had to pop hers because they were caught out then. Ichigo maintains that it was not his fault as the Gigai were difficult to control. Mentally, Yoruichi curses Urahara for not developing better equipment for them to use.

The trio close in on the Senkaimon and Yoruichi insists they will soon break through it. However, they are soon surprised when Yoruichi is knocked backwards, causing Ichigo and Rukia to stop when they realize that the Reigai clone of Byakuya Kuchiki is physically blocking the entrance. Byakuya's replica arrogantly asks them whether they actually thought he would be oblivious to their plan. Despite this, Yoruichi fools the Reigai, appearing behind him and easily slamming into his back. She maintains that she was aware of his own plan to intercept them the entire time.

Byakuya's copy demands to know if Yoruichi is now going to sacrifice herself for the sake of Ichigo and Rukia. She responds by kicking him to the ground and landing between her comrades and the Reigai, making her stand. Ichigo is reluctant to leave her but she insists she will be fine and that he needs to protect those in the Human World. Ichigo and Rukia pass through the Senkaimon and the other Reigai move to make chase. However, declaring that she will not let them pass, Yoruichi soon activates Shunkō and easily knocks all the lieutenant clones back.

Left facing the captains, Yoruichi explains that because the Reigai were made to battle, they are more aggressive that the originals and that's how her plan worked, because they so readily attacked the Gigai without holding back. Yoruichi goes on to declare once more that she will let none of them pass. Byakuya's clone refutes this insisting they only have to eliminate her. When she still holds them back, Yoruichi mocks their abilities and insists they should be able to do better. Byakuya's copy decides to release his Shikai and Yoruichi comments that his refusal to give up is quite like the real Byakuya's stubbornness. She then tries to avoid the Reigai's multiple petal blades, but the seem to intercept and encompass her before she can get away.

Aftermath
Ichigo and Rukia manage to arrive in the Human World in time to stop Kagerōza Inaba from harming Orihime Inoue. Ichigo faces off against Inaba before the real Gotei 13 reveal themselves. Inaba then retreats to the Soul Society, unworried about the current situation, assembling his massive Reigai army to plan their next move in a meeting.
