The Ghost in the Closet
A mysterious ghost girl who inhabits Max's closet. While viewers can see her clearly, she remains invisible to almost everyone in her world—Max, Maou, and Zenia can't perceive her at all. Fred is one of the rare exceptions; he could actually sense her presence, which freaked him out enough to bail from Max's apartment when they ran into each other again after Maou's defeat.
Interestingly, even though Maou generally can't see her, she sometimes picks up on the ghost's existence anyway. Occasionally Maou will hear what she's saying, creating these odd moments where she's reacting to something no one else can detect.
