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

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, she 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 cause 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 became of the Reigai. She states that mere impostors would never get the better of her, as Ichigo comments upon her superior speed.

Rukia informs Yoruichi that the Reigai have probably took 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 she reiterates that Yoruichi told them that the imposters have strengths 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 imposters.

Battle
Ichigo, Yoruichi and Rukia land upon a rooftop, and the Reigai are instantly alerted to their presence. The other Reigai appear in the courtyard, as Ichigo realises that more of them have arrived. Yoruichi states that they 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 continues, stating that they have no need to fight back, and that all they need to do is punch through their defensive wall.

The three of them jump towards the courtyard, as Reigai-Shūhei Hisagi notes that they are preparing to attack. Reigai-Tōshirō Hitsugaya states that all they need to do is prevent them from going through the Senkaimon, drawing his katana. He explains that in order to do so, they must hinder their advance, as Rukia blocks a direct strike from Reigai-Renji Abarai's Zanpakutō. At the same time, Reigai-Ikkaku Madarame attacks Ichigo, as Rukia is thrown back towards the ground. The Reigai appears in front of her, but as she moves in to attack him, her Zanpakutō is coiled by Reigai-Shūhei's Zanpakutō.



Ichigo calls out to her, but Reigai-Ikkaku tells him not to get distracted, moving in for another attack. He gets knocked to the ground by the Reigai's attack, but before he can regain his senses, Reigai-Tetsuzaemon Iba charges behind him, slamming his Zanpakutō down. However, Ichigo uses Shunpo to evade the attack, the ground crumbling where he previously stood. He regroups beside Rukia, as the three Reigai proceed to surround them. As Yoruichi travels along the ground, Reigai-Sajin Komamura strikes directly at her, causing her to double back.

As she jumps back, Reigai-Tōshirō Hitsugaya intervenes, using Hyōrusenbi. However, as she goes on the defensive once again, Reigai-Sajin strikes down with his Shikai, resulting in her inflatable Gigai detonating before their eyes. On cue, both Rukia and Ichigo's portable Gigai detonate, moments before the Reigai can strike them down. Reigai-Renji is surprised, as Reigai-Ikkaku states that he didn't do anything. Reigai-Hitsugaya and Komamura look around uneasily, wondering what transpired. Suddenly, Ichigo fires a Getsuga Tenshō, which proceeds to travel along the courtyard, before destroying a large portion of the Senkaimon gate.



Reigai-Tōshirō Hitsugaya flinches, as the three fugitives run across the ruined courtyard, using Ichigo's attack as a diversion. Rukia berates Ichigo for letting her lose control of the timing, but Ichigo states that the devices are very difficult to control. As they run, Yoruichi makes a mental note to get Kisuke Urahara to invent something easier to operate. However, as Yoruichi proclaims that they will break through the Senkaimon, she is knocked backwards. Rukia and Ichigo stop in their tracks, as Reigai-Byakuya Kuchiki appears before the Senkaimon, asking whether they thought he would be oblivious to their plans.

However, Yoruichi smirks, and knocks Byakuya off the rock face. She then repeats his taunting statement, as Reigai-Byakuya asks whether she is sacrificing herself for the sakes of her comrades. Yoruichi then hurls him across the courtyard, turning to face the three captain-class Reigai. Ichigo calls out to her, asking what she is doing, but Yoruichi tells him to go on ahead. Yoruichi states that she isn't about to get killed by mere imposters, telling Ichigo to protect the people in the Human World. He realises her motives, and apologises, heading out into the Senkaimon.



Reigai-Tōshirō Hitsugaya calls out to the other Reigai, telling them to prevent them from leaving. As Ichigo and Rukia enter the Senkaimon, the lieutenant-class Reigai attempt to move past Yoruichi. However, Yoruichi valiantly states that none of them will make it past her, releasing her Shunkō. She proceeds to defeat the Reigai of Renji Abarai, Tetsuzaemon Iba and Ikkaku Madarame through the use of her Shunkō, leaving only the captain-class Reigai left. She approaches Reigai-Byakuya, commenting that their situations have been reversed. Yoruichi states that, since they weren't hesitant to attack the three of them, their strategy was effective.

She reiterates that none of them will pass this point, taking up a defensive stance. Byakuya refutes this statement, explaining that all they merely need to do is eliminate her. Yoruichi commends their abilities, and that even for mere copies of the originals, their powers are impressive. She states that, even though they are Reigai, they are copies of several captains of the Gotei 13, asking whether that is all their combined strength amounts to. Reigai-Byakuya asks whether Yoruichi understands the situation she is in, to which he releases his Shikai, his katana disintegrating into petals.

Yoruichi comments that his refusal to admit defeat is akin to that of the real Byakuya, moving to dodge the swarming petals. However, as she jumps into the air, the petals intercept her movements, heading directly for her.

Aftermath
Ichigo Kurosaki and the Gotei 13 face off against Kageroza Inaba in the Human World, leaving the remainder of this fight unknown.
