Byakuya's Betrayal: Revealed

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 Hitsugaya's reiatsu weakining, as they proceed to go to the scene.

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.

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
