Haineko

灰猫

Haineko is the manifested spirit of Rangiku Matsumoto's Zanpakutō, appearing during the Zanpakutō Unknown Tales arc.
Haineko's spirit appears as a werecat. Although she looks mostly humanoid, she has a tail, cat ears, and pink fur covering her body. Her most notable traits are her large hips and rear, which contrast with Rangiku Matsumoto's large breasts. She is very mischievous and gets bored quite easily. She also seems to enjoy teasing Matsumoto.
