Rangiku Matsumoto vs. Izuru Kira

Rangiku Matsumoto vs. Izuru Kira takes place during the Ryoka Invasion when all of Soul Society is in turmoil over the intrusion by the Ryoka namely Kurosaki Ichigo, Uryū Ishida, Orihime Inoue, Ganju Shiba and Yoruichi Shihōin. However, Tōshirō Hitsugaya, the Tenth Division Captain suspecting something off with the murder of Sosuke Aizen goes to the Central 46 Chambers to investigate with his Lieutenant, Rangiku Matsumoto. He finds the Central 46 massacred but is interrupted by the arrival of Izuru Kira, lieutenant of the 3rd Division. They follow him out but Kira asks him if he should be follwing him instead of protecting Hinamori Momo lieutenant of the 5th Division whom he had left in the 10th division's barracks safe within a barrier. But Kira tells him that his barrier though strong against outside attacks is easy to break from within and that Momo had been following Hitsugaya all along. Hearing this Hitsugaya leaves Rangiku Matsumoto to deal with Izuru Kira and goes back looking for Momo Hinamori.

Battle
After Tōshirō Hitsugaya leaves Kira stops running and confronts Rangiku. She asks him what is Ichimaru Gin involving him in. Kira then asks if she knows the special ability of his Zanpakutō, Wabisuke and she tells him that he does not talk about such things but he tells her that Momo Hinamori and Renji Abarai both know. Then he tells her that he would let her know too. Kira releases his Zanpakutō, Wabisuke and proceeds to attack Rangiku but she blocks his attacks with her sword. However, she is left unable to lift her own sword. Kira tells her that his Wabisuke is able to double the weight of whatever it strikes and therefore if he strikes twice then the weight is doubled once again and with a third it is doubled yet again. The opponent is bent down due to the weight of his sword sticking his head out, hence the name, Wabisuke, the Apologizer. Rangiku then tells him that if her sword is too heavy to be carried then she would not hold it at all and releases her Zanpakutō, Haineko, Ash Cat. Her Haineko turns into ash and is able to slice anything that comes into contact with it. They begin to fight.

Aftermath
After the Conspiracy of Sosuke Aizen and his accomplices, Ichimaru Gin and Kaname Tousen is revealed, Rangiku Matsumoto is seen pondering about her Captain Tōshirō Hitsugaya having lost. Izuru Kira is seen suffering from slight scratches and in a state of shock after hearing that Hinamori Momo had been apparently killed although his Captain Ichimaru Gin had promised that she would not be harmed.
