Kazeshini is the manifested spirit of Shūhei Hisagi Zanpakuto that is seen during the Zanpakutō Unknown Tales arc.

Character Outline
The spirit of Kazeshini takes the form a dark man almost resembling a shadow. He has long black hair and carries a weapon similar to that of Shūhei's Shikai. Just as his image suggests he is violent and prone to rampages, and enjoys slashing his opponents. His behaviour may be why Hisagi does not like his zanpakutō.

Synopsis
He first appears when several Zanpakuto spirits are in a cave waiting for Muramasa's return. He is later seen in Soul Society taking on multiple Shinigami at the same time and dispatching them within seconds. He is last seen along with the rest of the Zanpakuto spirits appearing before the Shinigami that have gathered at the Sōkyoku Hill.
