Character Profile: Soul Piper

The Soul Piper is a round, white-ish demon that has a yellow pipe that it plays, and it plays with the souls of dead children until they can accept their death. Each time a certain soul does wrong, the Soul Piper's eyes open a bit more. When its eyes have opened completely, the Soul Piper wraps the soul of the child in chains and takes it to the place of its death, where a vortex opens and the soul is pulled by the chains into the depths of hell.

Kagome calls it a poltergeist, or ghost. She goes in it to save a child, Mayu, who thanks her. She almost went to hell herself! Only humans can enter this vortex, thus Inuyasha couldn't go near the portal to hell because he is half demon.
