That girl is a poor excuse for a "kami-sama"── Fujisaki Touka receives a request to investigate a strange case. It is a bizarre case of human karma that can only be solved by someone with the power of the "kami-sama." With her human form, she has the unique ability to touch things in the ethereal world, which allows her to trace the path towards solving the case. Her companion is the young man Saku Fujisaki, who was supposed to protect her as a follower of the "kami-sama." This is the story of a girl caught between dream and reality, and the companion who watches over her. (Source: Shogakukan, translated)
