Story
Janis is a student who had transferred from the United States, living in Japan for the second time (explaining how she can speak Japanese right away). First, she has a strange dream from the memories of the past in the Heian period. She was forced to move back after her father had yet another job transfer. It is in present-day Japan where she meets Kagome Higurashi. The two become fast friends. One day, Kagome is absent from school and Janis goes to check on her. Soon after she reaches the Higurashi Shrine, she is attacked by a demon and is almost killed. Janis is rescued, however, by a dark magical mask -wearing priest named Sen (or Monk Sen). He tells her that her destiny lies on the other side of the Bone Eater's Well. In the Sengoku period, she is reunited with Kagome and the others.

Something strange happens though. She touches a Shikon Jewel fragment and it melts into her body. According to Monk Sen, Janis possesses a divine spiritual power called Kamuitama, and says that she is the daughter of Kamui. The fragment inside Janis is even undetectable by Kagome. Janis joins the others in a quest to return the Kamuitama to the one who previously possessed it, a god known as Datara. Only then will she be able to remove the fragment and rid herself of the great power that makes her a target for demons.
