Shinidamachū

Shinidamachu (死魂虫 Shinidamachū, "Dead Soul Insects", English dub; "Soul Collectors") are long snake and insect-creatures. These creatures are a type of shikigami.

Point in Story
The Shinidamachu's first appearance is in Kikyō's second appearance after she was resurrected. The Shinidamachu's goal is to collects souls and bring them to Kikyō. They gather lost souls of the dead, and give them to Kikyō, so that she may continue her existence in the world of the living.

Creation & Powers
They do not serve for fighting as they were never seen fighting. Despite this, they seem to be strong, as five of them can lift a person up and fly away with the person. They also can steal the souls of the living, making them the controllers' mindless slave. Additionally, they were seen to be able to bind and immobilize people. At one point in the series, Naraku attempts to kill Kikyō by summoning his own giant Shinidamachu and sends it flying across the sky, collecting all the dead souls, including Kikyō's. They are also shown to have the power of intangibilty as they one passed through the wooden walls of the hut to come to Inuyasha. They also have the power to enchance Kikyō's spiritual powers greatly by delivering souls to aid her

They behave somewhat emotionless, collecting souls for Kikyō and obeying her pleas anytime without hesitation, but they had already displayed some kind of defensive manner, when the giant Shinidamachuu attacked Kikyō, several of her own started attacking the giant Shinidamachu by slamming themselves into it, still, useless due the size and power of the giant Shinidamachu.They also follow Kikyō even inside a barrier that killed them, needing Kikyō to dismiss them for their own safety.
