Ghost in the Closet

The Ghost in the Closet is a mysterious ghost girl who lives in Max's closet.

Despite being visible to the viewer, few individuals in the realm are able to actually see her. Neither Max, Maou nor Zenia can sense her, but Fred could, causing him to flee Max's apartment in fear when they first reunited after Maou's defeat.

She bears a strong resemblance to Sadako from the Ring movie series.
