The manifested spirit of Rangiku Matsumoto's zanpakutou.
Haineko is the manifested spirit of Matsumoto's zanpakutou. She was first introduced during the Zanpakuto Spirit anime-only arc. She's a very mischievous, flirtatious and slightly sadistic spirit, and enjoys openly taunting her owner, often calling her an "old hag". She's also surprisingly caring when it comes to her fellow zanpakutou.
During her first appearance, she was under Muramasa's control, and, as such, openly opposed the Gotei 13 and helped to facilitate the Zanpakutou Rebellion. After being released from Muramasa's control, she became more amiable to her owner, although still arguing with Matsumoto at times. She also took an active part during the Beast Swords arc, where she harbors a crush on Narunosuke.
