Rangiku Matsumoto & Momo Hinamori vs. Haineko & Tobiume

Rangiku Matsumoto & Momo Hinamori vs. Haineko & Tobiume is a fight that takes place during the Zanpakutō Rebellion. It involves the 5th Division & 10th Division Lieutenants battling against their respective Zanpakutō spirits.

Prologue
Lieutenant Isane Kotetsu walks through the 4th Division barracks with Captain Retsu Unohana when they are informed that many more injured are arriving and that they need more medical personnel in order to deal with the increase in patients. Unohana requests that her lieutenant does what she can, to which Isane agrees. However, at first, she turns back to her superior, as if about to say something worrisome about the situation, before apologizing and moving on. In Unohana’s office, Captains Jūshirō Ukitake and Shunsui Kyōraku discuss how close they were to catching mulitple Zanpakutō spirits and what a shame it was that they had failed. Ukitake worries that Captain-level Zanpakutō spirits are bound to start attacking as well, but Kyōraku tells him to relax since everyone is trying so hard. They wonder how the 6th Division is doing without their Captain and just what Captain Byakuya Kuchiki is doing at this moment.

Lieutenant Momo Hinamori waits outside the barracks as Lieutenant Rangiku Matsumoto rushes towards her, apologizing for being so late. Having let the guards go, the two lieutenants decide it is their turn to go on duty. In another area, Ichigo Kurosaki pursues Byakuya, whom he had just seen on top of a nearby building, although Ichigo expresses doubt over why Byakuya would help the Zanpakutō spirits or if it really was Byakuya he’d seen.

Muramasa is walking through what appears to be the Forest of Menos, seemingly in a weakened state, although he does manage to destroy an attacking Hollow without much effort.

In the forests of Soul Society, Haineko and Tobiume walk about in search of Hyōrinmaru, whom they soon begin to argue over. Senbonzakura shows up as they argue, surprising the two of them. He asks where Muramasa is, but both deny having seen him. Haineko asks why he is looking for him, as Senbonzakura merely leaves without speaking another word. The two of the begin arguing again before spotting Ichigo running through the woods and, recognizing him, waste little time in confronting him. However, the both of them argue over who gets to fight him, confusing Ichigo and causing him to run away, not having time to deal with them. They refuse to let him get away, but Momo and Rangiku appear before they have a chance to engage in battle.

Battle
Haineko becomes upset that she both lost the chance to play with her new toy and was now being confronted by Rangiku, calling her an Old Hag, expressing how happy she is to be free of her. Rangiku expresses regret at ever talking to her Zanpakutō as if she were her equal and the two quickly engage in combat, with Haineko materializing her sword to clash with Rangiku’s own. Momo is glad that she found her Zanpakutō, letting Tobiume know how much she has missed her company. Tobiume declares that she doesn’t share this sentiment and that she is tired of sharing her life with somebody so weak and mocks Momo for her naïvety, reasoning this aspect of her personality as to why everyone always betrays her. Enraged, Momo attacks the spirit of her Zanpakutō, but Tobiume evades the attack and lands behind her calmly.

Rangiku and Haineko continue to trade blows, with Haineko managing to cut some of Rangiku’s hair. Haineko threatens to make her bald but Rangiku simply replies that she’d still look good, wondering if her Zanpakutō was always this talkative. Annoyed, Haineko unleashes her power and sends her ash cloud towards Rangiku, who runs out of the way. The ash cloud continues to chase Rangiku; Haineko is almost able to catch her until she is knocked over by Tobiume, who was sent flying when Momo used '''Bakudō #37. Tsuriboshi''' to block her attack. Haineko and Tobiume immediately begin to argue over whose fault the interruption was as Momo and Rangiku observe that their Zanpakutō don’t seen to get along; they become more perplexed when both of them confirm their hatred for each other.

Tobiume chases Momo through the forest, telling her to wait, letting her former master know how much her betrayal at the hands of Sōsuke Aizen had infuriated her as she had been unable to do anything. Now, Tobiume can barely look at Momo anymore and has decided to put her out of her misery, attacking her with fire balls, the force of which throws Momo against a tree. Haineko and Rangiku continue their conflict, and Haineko gains an upper hand when Rangiku is distracted by Momo getting hurt behind her. Haineko punches Rangiku across the face and starts to insult her again, which irritates Rangiku enough to physically retaliate by grabbing Haineko by the hair and the two of them continue their scrabble.

As Momo gets to her feet, Tobiume tries to manipulate her emotions by pretending that nobody cares about Momo, as not even Rangiku is looking her way to see if she is alright. In reality, Rangiku is busy fighting her own Zanpakutō, who unleashes her powers again, unleashing her ash cloud to surrounded her former master. Rangiku begins to recite a Kidō incantation just as Momo begins to do the same. Momo unleashes Bakudō #9. Hōrin that misses Tobiume, much to the Zanpakutō’s amusement. Rangiku shoots a Hadō #31. Shakkahō, which also misses Haineko and again the Zanpakutō makes fun of her. Suddenly, Haineko is captured by Momo’s attack, having not expected it. Tobiume is forced to dodge Rangiku’s blast which distracts her enough to allow Momo to capture her as well, allowing her to end the fight.

Aftermath
Tobiume and Haineko argue about being placed so close together as Momo and Rangiku reveal that it was their plan all along to distract their opponents in order to surprise them in that manner. Momo also reveals that she can’t wait to grow older like Rangiku so that she wasn’t as naïve as she was now. The two spirits still don’t understand and continue to antagonize one another, much to their masters’ aggravation.

Elsewhere, Muramasa consumes a strong Hollow in the forest after killing some other Gillian-class Menos. Ichigo and Captain Tōshirō Hitsugaya also meet up with and confront Hyōrinmaru, who has lost his memory and is not aware of who his master is.
