In the near future, a groundbreaking psychotherapy method known as PT has been developed. Using a device called the "DC Mini," it functions as a "dream detective," entering people's dreams to explore their unconscious minds. Before the government can pass legislation authorizing this advanced psychiatric technology, a prototype is stolen, causing chaos at the research facility. If it falls into the wrong hands, the device could be devastatingly misused, allowing a user to completely erase a dreamer's personality while they sleep. Renowned scientist Dr. Chiba Atsuko enters the dream world under her exotic alter ego, code name "PAPRIKA," to uncover who is behind the plot to sabotage the new invention.
