Uryū Ishida & Yasutora Sado vs. Muramasa & Senbonzakura

Uryū Ishida & Yasutora Sado vs. Muramasa & Senbonzakura is a fight taking place in the Zanpakutō Rebellion. It focuses upon the conflict with Muramasa, Senbonzakura, Uryū and Sado after the former's arrival in the Real World.

Prologue
As Muramasa appears in Karakura Town, he lands in a forest area. He comments that Kōga is here, a faint smile appearing upon his face. He tells Kōga to wait a little while longer, wiping streaks of blood off his face. As he proceeds through the trees, he senses the presence of Orihime Inoue. Muramasa turns to face her direction, as she appears before him. He questions who she is, materializing his sword, preparing to cut her down.

However, Orihime activates her Santen Kesshun ability, blocking his strike. He moves back, and is surprised by her ability. She states that this is their town, but is stopped in mid-sentence by Muramasa, who activates his powers, preventing her body from moving. He is suddenly overcome by a coughing fit, freeing Orihime from his powers. He states that he is so close, and staggers toward the resting place of his Shinigami master, Kōga Kuchiki, shortly before collapsing.

As he lapses from unconsciousness, he realizes that he is being healed by the woman. However, she insists that he stay down, as she is not yet finished. Muramasa asks her what sort of being is she, to which she informs him that she was notified of his presence by Kisuke Urahara. He instantly presumes that she is allied with the Substitute Shinigami, wondering why she is helping him. She states that she cannot look away whilst someone is hurt, friend or foe.

He states that he is the enemy of Ichigo Kurosaki, which confirms Orihime's suspicions. However, she persists stating that he was truly suffering, as he dispels her protective barrier. Muramasa stands up, as Orihime senses his malignant reiatsu, likening it to that of an Arrancar's. He senses the presence of other individuals, using Shunpo to avoid a volley of arrows from Uryū's Ginrei Kojaku. Yasutora Sado appears alongside him, as Muramasa asks Orihime whether she lured him out here.

Uryū asks Muramasa whether he is their surprise visitor from Soul Society, as Sado inquires whether Orihime was injured by him. She reassures her comrades, stating that she wasn't harmed. Uryū senses his reiatsu, and observes that it is different from that of a Shinigami or an Arrancar, and asks who he is. Muramasa counters, asking him whether he is a friend of the Shinigami. He denies this, stating that he is in fact a Quincy, but Muramasa states that he has never heard of such a race.

Battle
He charges at the two, quickly dodging several of Uryū's arrows. Sado joins in the fight, preparing to attack Muramasa, who dodges. As they engage against the Zanpakutō spirit, they find themselves increasingly unable to land a hit upon him. Sado rushes up to him, releasing an El Directo attack, which Muramasa is able to evade through the use of Shunpo. The resultant aftershock causes a disturbance in the water, prompting Uryūto call out to him.

Muramasa states that he does not have enough time to fight them, resorting to the use of his illusionary abilities. His powers proceed to distort the surrounding area, as Uryū is caught off guard by the illusions. Muramasa charges at the oblivious Quincy, preparing to cut him down. However, Sado intervenes, emerging from the lake. He fires another El Directo attack, causing Muramasa to fall back. He curses their tenacity, stating that he is so close, yet so far.

Uryū instructs Sado to split up, as they converge upon Muramasa from opposite sides. Sado fires another blast from his hand, forcing him to seek refuge in the air. Uryūappears in front of Muramasa, stating that he has fallen directly into his trap, firing off an array of arrows at the defenceless Zanpakutō spirit. However, Senbonzakura intervenes, preventing the arrows from reaching him. The two of them are surprised at this, as Sado recognizes the attack as that of Byakuya Kuchiki's Zanpakutō, Senbonzakura.

Senbonzakura tells them to halt, stating that he should be the one to fight them, and not Muramasa. Uryū realizes that he is also a part of the Rebellion, as Senbonzakura releases his Shikai, forcing the Quincy on the move. Sado calls out to him, as Muramasa releases his powers on Sado, stating that he is in no position to be concerned about anyone but himself. He is then drawn into the vortex, appearing in downtown Mexico. He wonders where he is, as Oscar Joaquín de la Rosa appears before him.

He addresses his grandfather appropriately, before being punched in the stomach by him. Sado coughs out saliva, promptly collapsing to the ground. Muramasa then appears, as Sado struggles for breath on the ground. He comments that Sado is definitely not a Shinigami, and that he is no longer of any interest to him. As Muramasa walks away, he grabs his arm firmly, as he wonders how Sado can still move. He forces Sado into submission, who clutches his neck, as if he cannot breathe.

Then, Sado collapses onto the ground unconscious, as Orihime immediately rushes to his aid. Muramasa states that she is wasting his time, and that he is in no position to fight. Muramasa and Orihime are alerted to the ongoing battle between Uryū and Senbonzakura. Uryū fires another volley of arrows at Senbonzakura, who counters with his swarming petals. As the attack makes little headway, he fires several arrows into the air, which turn to attack Senbonzakura.

He resorts to Bankai, immersing his body in a protective shield composed of the petals, which is able to deflect all of Uryū's arrows. The petals proceed to swarm after Uryū, who once again appears before Muramasa. Senbonzakura appears at Muramasa's side once more, as the Zanpakutō spirit once again releases his powers upon Uryū. However, this time Orihime intervenes, protecting Uryū with her Santen Kesshun. Orihime questions why he is doing this, stating that she is aware of the sadness within Muramasa.

She repeats her question, as Muramasa berates her for thinking she knows all about him. He reveals his name to the two of them, stating that he has the power to change the world. He releases an abhorrent tide of dark reiatsu, as Rukia Kuchiki intervenes, utilising Hado #33 Sokatsui. Muramasa turns to face her, slicing her Kidō spell in half with his sword. She appears before the others, asking whether they are alright. They inform her of the current situation, as Senbonzakura inquires as to how she was able to find them.

She states that she merely needed to trace her brother's reiatsu, telling the others to stay on guard, as the man standing before them is directly responsible for the materialization of the Zanpakutō in Seireitei. Uryū then wonders what brought him to the Real World, asking where Ichigo is. Muramasa informs the group that he has probably been burned alive by Ryūjin Jakka's inferno. Rukia disputes this, stating that it would be impossible for him to take control of the Captain-Commander's Zanpakutō, but Muramasa informs her that this is the case.

Orihime states that she believes in Ichigo's abilities, and that he will most definitely come back. Muramasa collapses once more in a coughing fit, as Senbonzakura asks him if everything is going to plan. He states that it is, but he needs to hurry, releasing his malignant reiatsu once again. Numerous Hollow emerge from the writhing mass, as Orihime now understands why his reiatsu was akin to that of an Arrancar's. Rukia questions why he kept Hollows inside his body, to which Muramasa states his true purpose.

Kōga's Revival
As he leaves their company, Uryū attempts to prevent him from leaving, but Senbonzakura blocks his attack. The Hollow approach them, as Rukia tells Orihime to take the injured Sado away from their location. Rukia fires another Sokatsui spell, attacking the approaching Hollows. As Muramasa stumbles upon the central island, he reassures himself, stating that he is nearly there. He reaches the tree in the center of the island, stating that he has finally made it.

He groans momentarily, before uttering the release chant, as Sado is propped up against a tree by Orihime. She tells Rukia that they shall be alright, telling her to go after Muramasa. Before she can move, a Hollow catch up to them, but is quickly dispatched by the injured Sado. He tells Rukia to move ahead, as Uryū notices the tree crackling with energy, amidst his battle against Byakuya Kuchiki's Zanpakutō. He states that they have to do something soon, as Senbonzakura takes advantage of his distraction.

He swings his blade down upon Uryū, who blocks his strike with Seele Schneider. Senbonzakura is surprised at this, as Muramasa finishes the chant. The tree shatters into fragments of glass, as Rukia wonders whether the tree was in fact a seal. As Uryū uses Seele Schneider to clash with Senbonzakura, he comments that he didn't expect a Quincy to use a sword in battle. He states that he will never be able to defeat him with a weapon he is unfamiliar with, as he pushes Uryū backwards.

As Senbonzakura releases his Shikai, the petals disperse into small fragments, much to his surprise. Uryū explains that his weapon is not a sword, but in fact an object that is designed to weaken reishi bonds, and convert it into usable energy. He proceeds to absorb this energy into his Ginrei Kojaku, firing his Seele Schneider at a surprised Senbonzakura, knocking him backwards. He then uses Hirenkyaku to leave the scene.

Muramasa stands before Kōga's seal, commenting that he has waited so long for this opportunity. However, Rukia uses Hado #33 Sokatsui, interrupting the ceremony. Muramasa cuts through her attack effortlessly, proceeding to subdue her before she is able to fire off another shot. He tells her not to interfere, as Uryū prepares to come to her aid. However, Senbonzakura intervenes, attacking with his Shikai once more, the lower half of his mask shattered clean off.

Rukia asks him what that coffin is, to which Muramasa explains that it holds his Shinigami master, Kō﻿ga Kuchiki, who was once a powerful Shinigami who attempted to take over Soul Society. He states his goal to be Kō﻿ga's revival, and that all his plans have been leading up to this very moment. Muramasa's eyes glow with a purple tint, as the coffin proceeds to crackle with electricity. As a result of this, the bonds and chains shackling the coffin break off, as it radiates an amethyst hue.

It proceeds to dissolve before their eyes, exploding in a bright column of light. Kōga's wizened body appears before them, as Muramasa tosses Rukia aside; fixated with the release of his master. As Muramasa prepares to greet his master, Ichigo intervenes, clashing swords with him, before being pushed away. The others are alerted to his arrival, as he apologizes to Rukia for his lateness. Muramasa wonders how he escaped the clutches of Ryūjin Jakka, but states that it doesn't matter, because he is too late.

As Kōga's body crackles with static, Muramasa laughs loudly, proclaiming that his dream has come true.

Aftemath
After Muramasa released Kōga's body from his seal, he approaches his former master, who promptly stabs him in the gut. Muramasa wonders why his own master did this to him, as Kōga breaks his katana, causing his reiatsu to go out of control. Senbonzakura then explains to the Shinigami that Byakuya's motive was to find and kill Kōga, for having tainted the vestige of the Kuchiki Clan several hundreds of years ago.
