According to Shūhei, Kazeshini is by nature loves to kill and once he finds a target, he will continue to hunt it until he kills it.

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. As Kazeshini seemed ready to claim victory, Kira appeared in time to restrain him and escape with Shuhei.

Later, he appears in the cave arguing with Gegetsuburi. He than receives new orders to capture Ichigo Kurosaki.

When Byakuya Kuchiki is brought to the hideout, Kazeshini is against it, saying that he is probably there to stop Muramasa. However, after he defeats Sode no Shirayuki, he is convinced.

Afterward, he appears at the 6th Division barracks with the other Zanpakutō spirits. He suggests that they kill Renji and Rukia but before they can do so, they are surrounded by the Onmitsukidō. Kazeshini, nonplussed by the numerically superior forces, decided to kill everyone. He rips through several Shinigami easily but then, he is countered by Kira, who takes him away from the others to fight. After a brief exchange of words, the two fight. Kira, after using Kidō to counter the spirit's Kusarigama, is able to make a small cut in Kazeshini's scarf.

As the fight progresses, Kazeshini applauds Kira for dodging all of his strikes. Kira then warns Kazeshini not to continue fighting or be faced against his Zanpakutō's weight-enhancing power. Unsure if this was a bluff or not, Kazeshini decided to attack. Unfortunately for him, his uncertainly gave Kira the opening to subdue Kazeshini, slashing him across the chest and trapping him with Bakudō #63, Sajō Sabaku. However, Kira is interrupted by the spirit of his own Zanpakutō, Wabisuke, who defeats him. .

After the fight at the 6th Division barracks, Kazeshini is seen to have escaped back to the Zanpakutōs' hideout. He is collapses from a grievous injury on his back and questions Muramasa on why they were allowing a Shinigami (Byakuya) in their midst. Muramasa answers that Byakuya is "an important guest" to achieve their greater objective. When Yoruichi Shihōin leads Jūshirō Ukitake, Kenpachi Zaraki, Shunsui Kyōraku, and Ichigo Kurosaki to the Zanpakutōs' hideout, Minazuki leads Ichigo to a still injured Kazeshini. Kazeshini then briefly battles Ichigo but is soon defeated when Ichigo releases his Bankai and uses Getsuga Tenshō on the Zanpakutō, reverting Kazeshini to a broken Shikai state.

Later, Kazeshini is restored to normal by Captain Mayuri analyzing and removing Muramasa's influence on the Zanpakutō.

Unlike the other Zanpakutō spirits that are restored by Captain Mayuri, Kazeshini continues to go rogue with a strong desire to kill Hisagi. As Hisagi continues his job to take care of the Tōjū attacking the Soul Society, Kazeshini continues to attack Hisagi, each time ending with him being defeated. Despite his constant loses, Hisagi refuses to strike down Kazeshini until he fights him head on. During another attempt, Hisagi is injured by Kazeshini due to him protecting some civilians. After Kazeshini is again defeated, and wondering why Hisagi is so concerned about others' well-being, Kazeshini comes across a Toju who has just cut down someone. The rogue Zanpakuto asks him if he is a Shinigami, but before Kazeshini can give an answer, he is attacked by the former. But, he is able to cut down the Toju with little effort. Upon exiting the hut, Kazeshini notices a baby staring at him. Before dying of his injuries, the Toju's victim begs Kazeshini to watch over his child, this leads the latter to initially ignore his pleas. As the child continues to latch on to him in joy, Kazeshini finds himself unable to abandon the child. During his reluctant decision to take care of the child, the other Zanpakutō spirits laugh at seeing the blood-lusting spirit care for a child. Kazeshini also attempts to fight Hisagi again, but keeps getting sidetracked by the infant. Despite his annoyance, Kazeshini soon finds himself warming up to the child. Eventually Kazeshini finds a hut to leave the kid while he goes after Hisagi, but when hears the child crying, he returns to see a woman wishing to care for the child. While distracted, a Tōjū attacks. Rather then evading, Kazeshini finds himself shielding the child with his body. After striking down the Tōjū, Kazeshini begins to understand why Hisagi follows his beliefs of protecting others. Deciding it would be best for the child, he gives it to the woman and finally decides to face Hisagi head on. During their fight, Hisagi reveals he knows about the child, but Kazeshini denies such an involvement. After Hisagi finally strikes down Kazeshini, Kazeshini calls out to the child, currently crying from his departure, not to cry. Kazeshini then asks Hisagi what they will do once he changes back to normal. Hisgai says they will protect people together, which Kazeshini halfheartedly says he won't like.

The blades are connected to a spiked rod tethered together by a long chain. These blades can be swung by their chain in large circles, allowing the bladed portion to spin like a fan.
