Gotei 13 vs. The Reigai

The Gotei 13 vs. The Reigai is the final battle between the Reigai and the Gotei 13 during the Reigai Uprising. The Gotei 13 take on the Reigai Invasion force created by Kagerōza Inaba as Ichigo Kurosaki and his friends fight against the newly resurrected Ōko Yushima

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 assume 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 taunts 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.

Each captain continues in their battle against the Reigai captains. Captain Zaraki is locking blades with his Reigai double, Hitsugaya and Reigai-Hitsugaya are unleashing their Shikai at each other, which cancel each other out. Byakuya and Reigai-Byakuya keep using Shunpo to cross blades each other. As the two briefly pause to lock swords, Reigai-Byakuya again asserts that he is the true head of the Kuchiki clan. He then breaks the deadlock and Byakuya is repelled back. Byakuya comes back to back with Kenpachi, as Kenpachi casually asks if Byakuya needs some help as it appeared that Reigai-Byakuya is giving him trouble. Byakuya rejects the offers and tells Kenpachi to not interfere. He then counters with his own offer to help if Kenpachi has having trouble. Kenpachi only chuckles and heads out to fight again. As Reigai-Kenpachi and Kenpachi exchange sword strikes once more, the Reigai comments on how he is having too much fun. Kenpachi then asserts that he will be the one to  kill Reigai-Kenpachi and for Byakuya to not interfere in his fight. Over at Kyōraku's and Ukitake's end, the two exchange attacks with their Reigai before using Shunpo to be back to back with each other. As the Reigai face them from atop nearby roofs, Kyōraku notes to Ukitake that he thinks the Reigai have the edge in this battle. Ukitake agrees, stating that the Reigai's capabilities have significantly improved and curses Kagerōza Inaba for doing so. Kyōraku suggests that they kill one Reigai per person, but then jokes that maybe it is two per person Ukitake scolds Kyōraku to stop fooling around and prepare as the Reigai are about to attack. Reigai-Shunsui Kyōraku proceeds to use Bushōgoma. Both immediately dodge as the wind blades destroy the surface that the two were just at. Kyōraku, who had jumped into the air to dodge, compliments the Reigai on using a nice imitation of his Bushōgoma technique. He then uses his own Bushōgoma against the Reigai. However, Reigai-Jūshirō Ukitake intervenes by using his Sōgyo no Kotowari to absorb and redirect the attack back at Kyōraku. Kyōraku is slightly surprised and as he lands, he braces himself for the attack. But, Ukitake intervenes in a similar manner and returns the redirected attack back at the two Reigai with his Shikai. Both Reigai dodge with Shunpo and Kyōraku compliments Ukitake on an excellent move with a Sōgyo no Kotowari return fire. Ukitake once again scolds Kyōraku, saying that this is no time for jokes. Kyōraku agrees, stating joking in this battle does seem inappropriate. As the two watch the other battles, they see that their fellow captains are not having an easy time. Kenpachi and Byakuya are both on the defensive, and Captain Komamura is finding himself fighting against five Reigai versions of the lieutenants (Lieutenants Abarai, Kira, Iba, Matsumoto and Hisagi). Yoruichi appears at Kyōraku and Ukitake side, saying that she believes that they ought to pull back for the moment. Ukitake understands, and calls for Hitsugaya, Byakuya, and Komamura to pull back. But, Hitsugaya appears nearby the three and tells them that he is not backing down. While both Captain Kuchiki and his Reigai double look on at this development, the Reigai quickly asserts that it is futile trying to escape. Byakuya re-assumes his battle position as the Reigai prepares to use Bankai, asserting that he will defeat the original. The Reigai unleashes the Gōkei technique of his Bankai. The other Reigai also attack with Reigai-Shunsui Kyōraku using Bushōgoma, Reigai-Tōshirō Hitsugaya using Guncho Tsurara, Reigai-Kenpachi Zaraki using a slash attack with his Zanpakutō, and Reigai-Retsu Unohana firing Hadō #88  Hiryūgekizokushintenraihō. The resultant effect is large explosion, generating a massive cloud of smoke and debris.

As the smoke clears away, Yoruichi and Hitsugaya are both revealed to be relatively unharmed. Yoruichi is seen kneeling down and tells Hitsugaya that it unfortunately appears that they are at a disadvantage. Hitsugaya points his blade at Reigai-Hitsugaya and states they cannot afford to lose as the two glare at the Reigai, who is on the roof of a building. Reigai-Hitsugaya tells the two that the originals simply do not know when to give up and that they cannot win against the Reigai as his allies join him. Reigai-Shunsui Kyōraku states that the time has come for the Reigai to take the place of the originals, while Reigai-Ukitake tells them to give up already. Hitsugaya refuses to do so. His Reigai double asks why does he keep on fighting. Hitsugaya's responds back by telling the Reigai to not make him repeat himself as the other originals come by his side. He states that the captains of the Gotei 13 protect what must be protected, and that there is nothing else to it. Reigai-Hitsugaya notes this, but tells the originals that reasoning is also true for them. Reigai-Kenpachi scoffs at Reigai-Hitsugaya's claim. Reigai-Byakuya Kuchiki agrees that their reason for fighting is not quite the same as the originals and tells the Shinigami that they will show what sets the Reigai apart from them. The Reigai then assume battle positions again and make their charge. The Gotei 13 captains and Yoruichi ready themselves, as Hitsugaya takes the lead in taking on the Reigai. He reminds himself that he had swore an oath to protect and a burst of energy occurs as the Reigai and Shinigami rush at each other.
