Byakuya Kuchiki vs. Reigai-Byakuya Kuchiki

Byakuya Kuchiki vs. Reigai-Byakuya Kuchiki is a fight taking place in the Reigai Uprising. It is the conflict between Captain Byakuya Kuchiki and his Reigai copy, as Captains Kuchiki, Hitsugaya, Zaraki, and Komamura return to Soul Society in an attempt to stop Kageroza Inaba's plans.

Prologue
After returning to Soul Society, Captains Kuchiki, Hitsugaya, and Zaraki split up to deal with the enemy Reigai on their way towards Kageroza Inaba at the 12th Division barracks. As Captain Kuchiki made his way to Kageroza, he encountered the Reigai copy of Tōshirō Hitsugaya. The battle between the two was fierce, but Captain Kuchiki would be victorious, who once again continues to go towards Kageroza's location. Before he can get very far, he encounters his Reigai copy. He then states to the Reigai that he knew that he would be fighting his Reigai copy sooner or later. Reigai-Byakuya Kuchiki comments that his original counterpart is wounded, which Byakuya quickly disregards as being an issue. Reigai-Byakuya Kuchiki then tells him that he supposes it truly is not an issue, since he would never run, regardless of the situation. Byakuya Kuchiki tells his Reigai copy that he is going ahead, which prompts the Reigai to tell the original that he cannot allow that. Both then draw their blades and state that there can only be one Byakuya Kuchiki.

Aftermath
Byakuya Kuchiki is able to defeat his Reigai copy, after both of them released Bankai and exchanged one last attack with each other. Byakuya Kuchiki then finally is able to arrive at Kageroza's compound to confront the scientist, appearing along with other Gotei 13 captains and Yoruichi Shihōin as Kageroza is about to finish off Tōshirō Hitsugaya
