Prologue
During their previous engagement with Kagerōza Inaba and his Reigai Invasion Force, the Gotei 13 had found themselves being pushed back by the overwhelming force of the Reigai. However, Yoruichi Shihōin had taken the precaution of informing Kūkaku Shiba about the situation and so Kūkaku arrived with Jidanbō Ikkanzaka and Ganju Shiba to assist the captains. Thanks to Kūkaku's intervention, the Gotei 13 were able to retreat. They then treated their injuries at Kūkaku Shiba's home and awaited their next opportunity to strike. As Ichigo Kurosaki ventured into Soul Society with Kisuke Urahara and Kon in order to regain his lost Shinigami powers by converting the reishi he collected in the Dangai into a Mod Soul. Ichigo Kurosaki was able regain his lost power, but found his restored reiatsu highly unstable and so his Hollow powers could go out of control and take over him because he took an incomplete Mod Soul. Ichigo, Urahara and Kon then go to find Inaba's second lab, due to Inaba rigging his "official" equipment to destroy itself in anticipation of an intruder's attempt to use it. They quickly move out due to the explosion attracting attention from nearby Shinigami. As they rush outside, the three find themselves confronted by the Reigai army. Urahara tells Ichigo and Kon to flee as he tries to hold them off, but then Yoruichi Shihōin and the Gotei 13 captains arrive ready to fight the Reigai.

Relieved that Yoruichi and the Gotei 13 are all alive, Ichigo asks Yoruichi where they were all hiding. Yoruichi explains the details on how they managed to escape with the help of Kūkaku Shiba. Kenpachi Zaraki then attacks the Reigai and tells Ichigo, Urahara and Kon to get out of the way. Yoruichi tells the trio to leave the Reigai to them and they leave. The captains proceed to take on the Reigai.

Battle
The battle between the original Gotei 13 and their Reigai doubles gets under way at the S.R.D.I. Captain Byakuya Kuchiki faces off against his Reigai double. The blades from the Reigai's Shikai surrounds them as he tells Reigai-Byakuya Kuchiki that it is futile no matter how many times they fight as there is only one true head to the Kuchiki clan. The Reigai agrees and asserts that it is he who is the true head. He then sends his Shikai at Byakuya. As this happens, Kenpachi Zaraki and Reigai-Kenpachi Zaraki charge at each other. They both jump high into air and cut each other, both generating small craters and debris upon landing on the group. The Reigai tells his original that he is not bad while Kenpachi replies that he likes that his opponent still wants to fight. Both simultaneously state that the "fun starts now." Suì-Fēng and Yoruichi Shihōin make their charge against Reigai-Retsu Unohana. They attempt to strike her from her left and right side, but the Reigai generates Bakudō # 73. Tozanshō to block their attacks. Both are surprised to to see the Kidō barrier stopping them. The two desist in their attacks and move back. Yoruichi comments on how the Reigai has good reflexes, which Suì-Fēng notes as being a little too good. Yoruichi observes that the Reigai have improved their capabilities and thus they will have some difficulty defeating their opponents. The two adjust themselves into battle positions for their next move. Reigai-Sajin Komamura then uses his Shikai against Captains Shunsui Kyōraku and Jūshirō Ukitake, forcing the pair to quickly dodge the ferocious Reigai's giant sword strike. At Captain Tōshirō Hitsugaya's end, he is finding himself pushed back as the Reigai double sends him flying into a wall. The Reigai comments on how the original is no challenge at all, and how he supposes the original won't turn away from a Reigai and run due to his pride. Hitsugaya emerges from the debris, stating that this is not the case as it is simply the duty of the Gotei 13 to protect Soul Society.
