Kagura (lit. Music of the gods) is a wind sorceress created from Naraku's own body. Despite this, she has her own mind and is willing to fight desperately for freedom.
Her first appearance involves Kagura's use of the "Shikabane Mai," or "Dance of the Dead," to lure out Koga's companions and slaughter them. Following this, she splattered Inuyasha in the blood, causing Koga to arrive to "avenge his companions." Unbeknownst to Koga, he has a false Shikon no Tama shard rather than the real one-and upon severly injuring Inuyasha, he is immobilized by Kagura's fake. Assured that she has won the battle, Kagura steps forward to take the real shikon shards as well as Koga's life.
This is interrupted by Inuyasha, who proceeds to fight Kagura and is on the verge of being killed when he is finally able to interrupt Kagura's winds to unleash a Kaze no Kizu. Surprised, Kagura flees, briefly showing a spider-shaped burn scar on her back similar to Naraku's. She realizes that Naraku has been using her and proceeds to attack him, being stopped when he squeezes her heart and tells him that he holds her life in his hands. Since then, Kagura has worked to kill him, often using others.
