Plot Ritsu is a young man who has inherited the ability to see spirits and demons from his late grandfather, a renowned novelist and spiritualist. This "sixth sense" makes Ritsu visible to entities from the spirit world, leaving him vulnerable to good and evil forces. After his grandfather's death, Ritsu loses the protection he once had under his care and forms a contract with a demon guardian known as Blue Storm, whose motives are not always aligned with Ritsu's well-being. The series is structured as a collection of largely self-contained stories, centered on supernatural incidents that arise around Ritsu and Blue Storm.
