What are dreams, really? For Shin, it turns out, they are manifestations of his Persona, an ethereal being designed to protect Shin and fight other Personas. And Shin's not alone: his two brothers and several of his schoolmates have them as well. After learning of these entities and their abilities, Shin and his friends must be on their guard. Someone in Ayanagi city is stealing Personas and leaving their owners in a vegetative state or even dead, and the danger is closer to home than Shin knows.
