Когда лейтенант 5-ого отряда, Момо Хинамори имеет короткий разговор с лейтенантом 6-ого отряда, Ренджи Абараем, Рангику прерывает их. Она объясняет, что причина того, что так мало людей пришло на экстренное собрание лейтенантов из-за того, что очень много капитанов и лейтенантов в это время разбросаны по всему Обществу Душ на своих миссиях. Она отмечает, что займет по крайней мере половину дня, чтобы собрать всех вместе. Рангику также упоминает, что она не может найти своего капитана в любом месте, и Ренджи спрашивает, кто является ее капитаном. When the report is made that intruders have invaded the Seireitei Rangiku is among the others gathered at the meeting who are informed of those missing in action. When 7th Division Lieutenant Tetsuzaemon Iba notes that the 4th seat of his division is also missing in action, Rangiku asks him if that is Jirōbō the Kamaitachi, to which Iba states that it most likely is.
Rangiku and all of the other lieutenants are alerted when Momo lets out a scream, causing them all to rush to the scene. She then bears witness to the dead body of 5th Division Captain Sōsuke Aizen impaled to the wall of a building with his own sword. She is also the one who restrains Momo after her brief fight with Izuru Kira, when her captain, Tōshirō Hitsugaya orders them arrested.
She later comes and gives a letter from Captain Aizen to Momo while the latter is being kept in a 5th Division cell. Rangiku makes note that had her captain not found it the letter would have been taken in as evidence and Momo would have never seen it. Rangiku explains that she doesn't know what is in the letter but as a lieutenant she thinks it is a great honor to be a receiver of a captain's final words.
Later, when Hitsugaya faces off with 3rd Division Captain Gin Ichimaru, she stops Ichimaru’s blade from killing an unconscious Momo, thus saving her life. Rangiku apologizes, stating she was going to head back as Hitsugaya had instructed, but she felt the spiritual release of Hyōrinmaru and turned back around. She then tells Gin to put away his sword, as if he doesn't, she will be his opponent. After Gin retreats, she wonders where Ichimaru will go from there. While thus occupied with their own thoughts, a message comes via a Jigokuchō for them stating that the execution of Rukia Kuchiki was being pushed forward. Hitsugaya, determined to get to the bottom of the matter, realizes that the only way to do so would be to stop the execution.
Upon arriving at the Central Underground Assembly Hall Hitsugaya and Matsumoto discover all 46 members are dead. Hitsugaya surmises they have been dead for at least 2 days, but he is concerned about when as Soul Society has been under martial law and their Headquarters had been locked down since Renji's defeat. Further than that, the 13 seals of protection were still active and there were no signs of intrusion. Then Hitsugaya realizes the only possible scenario is that they were killed before they were sealed in and that all the recent orders have been in fact false. It is then that he realizes that such a plot would be far too elaborate for Gin to carry out by himself. He then is interrupted by Izuru and he and Matsumoto give chase. Asking Izuru if he was behind the Central 46's death, Izuru tells him no and that he arrived just after he did. He also informs Hitsugaya that instead of chasing him, he should be protecting Momo. He then goes on to explain that she escaped the 10th Division Barracks and how she accomplished it. Realizing now that Hinamori has been following him and Matsumoto the entire time he turns back and orders Matsumoto to handle Izuru.
When Izuru realizes that Rangiku is now after him and Hitsugaya has gone he stops running. When Rangiku asks him if he was done running, he explains that he has a mission to keep her there. When she asks who gave him that mission he tells her that Gin did. Rangiku tries to reason with him, but Izuru refuses to answer her further. He then tells her that the reason he refuses to answer her is because she is about to die. He then releases his Shikai. He asks Rangiku if she knows about his Zanpakutō's special ability. Rangiku plainly tells him that she doesn't and she assumes no one does as he has never spoken about it. Izuru explains that in fact his former classmates Renji and Momo know of it, but he assures her she will now know it as well. The two face off and Rangiku realizes that her Zanpakutō has become too heavy for her to hold up. Izuru explains the power of his Zanpakutō and tells her how it has affected hers. He notes that she can't carry around that weight. Rangiku explains that if her Zanpakutō is too heavy she just won't carry it. Rangiku then reveals that his weight-affecting Zanpakutō is rendered useless by her Zanpakutō's ability to dissolve into ash. After their fight, Rangiku hears from 4th Division Lieutenant Isane Kotetsu via Bakudō #77 "Tenteikūra" that Aizen, Gin, and Kaname Tōsen are traitors. Rangiku then runs off to find Hitsugaya.
When she arrives at the Sōkyoku, Aizen is captured. Before Gin can act, Rangiku appears behind him and grabs hold of his arm and places her Zanpakutō at his neck, asking him not to move and effectively placing him under arrest. When the Gillian’s Negación field comes down to save Ichimaru, however, she releases her hold upon him. Ichimaru then expresses his regret that she could have held onto him a little longer. He then bids her farewell and apologizes.
One week later, Izuru visits Rangiku in the 10th Division barracks to apologize. The two get drunk and comment on how they don't need Gin in an effort to remove the feeling of betrayal that they both felt, the events of the week before most likely forgiven.
