Byakuya's Betrayal: Revealed

Byakuya's Betrayal: Revealed is an event taking place in the Zanpakutō Rebellion, focusing upon the pivotal incident in which the 6th Division captain, Byakuya Kuchiki, reveals his allegiance to the Zanpakutō's cause.

Prologue
After Lieutenants Rangiku Matsumoto and Momo Hinamori defeat their Zanpakutō, they are immediately secured inside a carriage, as they attempt to reason with their Shinigami masters. However, they ignore them, telling the Shinigami operating the carriage to take Haineko and Tobiume immediately to the 4th Division barracks, as they proceed to leave the area. In their wake, another figure leaves in pursuit of the carriage. As the two Shinigami run, Momo senses Tōshirō Hitsugaya's reiatsu weakening, as they proceed to go to the scene.

Muramasa's Return
Ichigo Kurosaki crosses their path, as Rangiku crashes into him, promptly crushing him. She realizes that she accidentally sat upon Ichigo, and berates him for commenting upon her weight. Later, Rangiku asks whether he knows if Captain Hitsugaya is alright, to which Ichigo relays the aftermath of the fight to her. However, the three of them realize something is wrong, as Muramasa emerges from a Garganta, panting heavily. He states that he hasn't fully calibrated to his new body, sensing the presence of Ichigo and the others.

Muramasa states that he foresaw their meeting here, to which he assumes fate is somehow implicated. Ichigo merely states that he is going to defeat him, and that is the only thing that brings them together. Muramasa raises his hand to Ichigo, who wonders whether he will try and subjugate his Zanpakutō from him, to which Zangetsu reassures him, stating that the same trick does not work twice. Muramasa coughs repeatedly, as Momo senses his unstable reiatsu, to which he sends out an energy wave, proceeding to bind them with his spiritual threads.

Senbonzakura's Intervention
However, they are freed from his attack when Muramasa enters another coughing fit, as blood emerges in thin streaks from his eyes. Ichigo uses this temporary distraction, charging at Muramasa, attempting to cut him down, but is blocked by the sudden appearance of Senbonzakura. As he pushes Ichigo back, Muramasa smiles to himself, as Ichigo asks who his master is. Senbonzakura states that he will figure it out in time, releasing his Bankai, as Ichigo realizes that it is Byakuya Kuchiki's Zanpakutō. As the blades turn into the miniscule pink petals, Momo intervenes, releasing Bakudo #39 Enkosen, which she uses to shield herself and Rangiku from the attack.

However, it is unsuccessful, as Rangiku pushes her out of the way. Ichigo dispels the attack with a Getsuga Tenshō, commenting upon Senbonzakura's strength. He correctly identifies him as the Zanpakutō of Byakuya Kuchiki, which surprises him that he remembered. Meanwhile, the prison carriage moves slowly along, as the Shinigami guards sense a massive amount of reiatsu being released. One of them comments that it is the 6th Division captain's reiatsu, as an unknown figure proceeds to subdue the guards.

Haineko and Tobiume ask the figure what he means by doing this, as Momo and Rangiku back off, allowing Ichigo to fight Senbonzakura alone. Ichigo realizes why he has the same reiatsu as Byakuya, as he asks the Zanpakutō spirit whether he was the culprit behind the attack last night, to which Senbonzakura remains silent. Ichigo charges at Senbonzakura, who releases a swarm of pink petals, which he is able to dodge. As Senbonzakura walks into the clearing, Ichigo has vanished, as he predicts his next movement to come from above him.

However, Senbonzakura intercepts his attack, appearing behind him. He asks Ichigo whether he believed such an attack would prove successful against him, as he is pushed back, in close pursuit from the pink petals. Ichigo evades all of his attacks, appearing behind Senbonzakura. Senbonzakura intercepts his attack again, forcing Ichigo upon the defensive, blocking his attacks. He observes Ichigo's movements closely, as he uses Shunpo to create a multitude of clones. Ichigo appears above Senbonzakura, who blocks Ichigo's attack with his petals.

Ichigo tells Sebonzakura to think back to his original fight with Byakuya, releasing a black Getsuga Tenshō, which is able to destroy Senbonzakura's attack, hurtling him into the nearby structure forthwith. Senbonzakura pants heavily, trapping Ichigo inside his Gōkei, who explains the physiology behind the attack, as the writhing mass contracts slightly, before exploding. Senbonzakura states that he is finished, as Rangiku calls out to him. However, Ichigo is unscathed, as he dons his Hollow mask, with Senbonzakura commending his abilities.



Ichigo ponders whether it is corrrect to kill Byakuya's Zanpakutō, stating that he has no choice but to do so. Senbonzakura asks why he is hesitating, and releases Shūkei, which deflects Ichigo's point-blank black Getsuga. The two attacks collide together, beofre imploding, sending a shockwave hurtling throughout the area. Ichigo's Hollow mask dissipates, as Senbonzakura claims that his reiatsu claimed victory over him. Ichigo asks why he thinks so, as a fragment of Senbonzakura's mask shatters promptly.

The Betrayal
Senbonzakura clutches his left eye, wondering what occurred. Ichigo apologizes, stating that he has no chance of defeating him without the assistance of his Shinigami master. They argue briefly, as Senbonzakura prepares to attack Ichigo once more. However, Senbonzakura is stopped by that of Byakuya Kuchiki, who tells him to stop. The Shinigami are surprised by his sudden appearance, as Rangiku wonders what he is doing here. Byakuya faces Ichigo, and tells him to pull back, as Ichigo asks whether he is preparing to fight him.

However, Byakuya states that that is not the case, releasing Hado #33 Sōkatsui at Ichigo. He asks why Byakuya did that, who states that he will not allow him to attack Muramasa. Ichigo asks him why he is protecting Muramasa, to which he states that he is doing this of his own free will. Muramasa laughs, stating that he finds Byakuya to be an interesting Shinigami. Byakuya repeats his warning, stating that Ichigo will die if he persists to impede Muramasa's objectives.
