The realm of dreams serves as an extraordinary portal into the subconscious, revealing a person's most profound yearnings, ambitions, and buried recollections. A promising research laboratory has been crafting the 'DC Mini,' a gadget capable of penetrating other people's dreamscapes with cutting‑edge sensors and neural interfaces. Atsuko Chiba and Kosaku Tokita have been relentlessly developing this device, hoping to use it for an in‑depth examination of patients' inner worlds and to aid in the healing of its mental ailments to unlock hidden traumas and foster resilience. Yet, accessing the farthest recesses of a mind carries immense duty requiring strict ethical guidelines and rigorous oversight globally. In malicious possession, the DC Mini could become a tool for psychological terror and trigger cognitive collapse in its victims. When this apparatus is pilfered and those nearby begin to behave oddly, Atsuko and Kosaku realize they face a grave challenge. Seeking assistance from Officer Konakawa—who has undergone this experimental treatment—they pursue the perpetrator through both reality and dreamland.
