Kyōka Suigetsu (spirit)

"The best thing about dreams is that fleeting moment, when you are between asleep and awake, when you don't know the difference between reality and fantasy, when for just that one moment you feel with your entire soul that the dream is reality, and it really happened."

- Kyōka Suigetsu

Kyōka Suigetsu (鏡花水月, Mirror Flower, Water Moon) is the freed Zanpakutō of Sōsuke Aizen, and now works along with Hollow Ichigo in Bleach Shikkyakuhoshi. Similar to Hollow Ichigo's case, it is unknown how he was freed from Aizen, or how he teamed up with Hollow Ichigo.
