Supernatural events are merely a façade; the most terrifying scenes lie within the human heart. The world is unpredictable, and human nature is inscrutable. Some people possess such unfathomable cunning that they can use a radio to control eerie corpses with wings growing from their backs. Others possess such unparalleled intellect that they can use electrical currents to infiltrate others' minds. Magic? Technology? Who can tell the difference? The most powerful mind never relies on its own memories; it only manipulates the memories of others. Only the heart can unravel the mystery.
