Mai is an orphan girl who joins the Shibuya Psychic Research (SPR) after accidently breaking a camera (the camera turned out to be insured). As a member of the SPR she discovers that she has ESP and is capable of Post-cognitive dreams allowing her to see into the past, as well as clairvoyance and astral projection. Mai develops feelings for Kazuya Shibuya who she initially nicknamed "Naru" for his seemingly narcistic personality.
