Byakuya Kuchiki vs. Reigai-Tōshirō Hitsugaya

Byakuya Kuchiki vs. Reigai-Tōshirō Hitsugaya is a fight taking place in the Reigai Uprising. It focuses on the conflict between 6th Division Captain Byakuya Kuchiki and the Reigai counterpart of Captain Tōshirō Hitsugaya.

Prologue
Captain Byakuya Kuchiki walks across an archway of pillars, stopping briefly in his tracks. Reigai-Tōshirō Hitsugaya appears from behind one of the pillars, proclaiming that he was awaiting his presence. He outlines that his objective is to prevent anybody from moving past this point, stating that he will not give chase if Byakuya leaves. However, Byakuya stands his ground, explaining that he will eliminate anyone who stands in his way.

Hitsugaya grips his katana, stating that that will make his job easier. Byakuya follows suit, as Reigai-Hitsugaya releases his Bankai, the two opponents charging at one another.

Battle
Reigai-Hitsugaya roars, releasing an ice dragon from the tip of his Zanpakutō, as Byakuya counters this attack with his Shikai's petals. The two forces crash together in an explosion, conjuring up a cloud of smoke. Byakuya jumps to the ground, observing the scene. As the smoke clears, Reigai-Hitsugaya is nowhere to be seen. However, Byakuya simply glances above him, as the Reigai takes him by surprise. Reigai-Hitsugaya releases Sennen Hyōrō, promptly sealing Byakuya within it. As the Reigai lands safely upon the ground, Byakuya emerges behind him, slashing his chest.

Byakuya tells him to end his trickery, stating that the real Hitsugaya would never go down so easily. His form disintegrates into ice, as the real Reigai appears behind him. Reigai-Hitsugaya states that the same could be said of him, and that his tactic was woefully inadequate to capture someone of his caliber. He points his Zanpakutō at Byakuya, summoning a multitude of ice pillars beneath his feet. Byakuya manages to dodge them all, proceeding to lunge at Reigai-Hitsugaya. He clashes with him, before locking blades with the Reigai. As they struggle, Byakuya asks him why he follows Kageroza Inaba, to which Reigai-Hitsugaya reveals his surprise at Byakuya's attitude.

The Reigai asks how Byakuya would benefit from hearing the answer, to which he remains silent. The two then break off, as Reigai-Hitsugaya states that he wishes to protect something at all costs. He leaps into the air, utilising Sennen Hyōrō. Byakuya is instantly surrounded by ice pillars, wondering why Reigai-Hitsugaya is resorting to the same attack again. The Reigai charges at Byakuya once more, knocking him back to the ground. As he stands before the ice pillars, he realises Reigai-Hitsugaya's strategy, in which their sole purpose is to restrict his movement.

Reigai-Hitsugaya apologises to Byakuya from atop one of the pillars. He explains that he will fight his final battle against the original Hitsugaya, and that they both share what they wish to protect. However, Reigai-Hitsugaya claims that the original's power is insufficient to do so; stating that only their enhanced abilities as Reigai will make it possible. He resolves that he musn't lose to anyone until his destined battle with the original, releasing Hyōryūsenbi, much to Byakuya's surprise.
