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

Character Outline
The spirit of Kazeshini takes the form a dark man that almost resembles 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, prone to rampages and enjoys slashing his opponents.

Synopsis
He first appears when several Zanpakutō 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 Zanpakutō spirits appearing before the Shinigami that have gathered at the Sōkyoku Hill. He tries to attack Shūhei Hisagi and Tetsuzaemon Iba, who are carrying an unconscious Sajin Komamura, but Soifon blocks the attack. He is then seen ambushing Rukia Kuchiki and Renji Abarai, focusing on the latter.

The following day, he encounters Shūhei and severely injures the two Shinigami that are with him at the time while in a black tornado. Identifying the swiftness of the attack as Kazeshini, Shūhei questions why he's attacking, and he says that he heard a voice saying to "follow his instincts," which is to kill.

Trivia

 * Because of his long hair, pointed ears, and destructive personality, Kazeshini somewhat resembles the Espada Grimmjow Jaegerjaquez in his released state. His battle-loving, lunatic nature is also greatly reminiscent of the inner Hollow of Ichigo.
