The psychic investigators are going back to school - this time to solve a baffling mystery. Every student who sits at one particular desk is later caught in a train door and dragged away to who knows where. And when Naru and Mai find themselves stalked by their own evil spirits, the case becomes even more bizarre. Could this dastardly desk be the revenge of a quiet young girl named Chiaki? Or is there another unhappy soul to reckon with? One thing is certain: voodoo dolls, bad vibes, and sinister curses won't stop the psychic pals from solving their most difficult and dangerous case yet!
