Dr. Torataro Shima leads the psychiatric research team developing the DC Mini, a device designed for dream exploration and therapeutic use. A middle-aged man with white hair and thick, eye-magnifying glasses, he balances a cheerful, approachable presence with the demands of overseeing the project’s ethical implementation amid bureaucratic pressures. When stolen prototypes trigger a crisis, his mental unraveling culminates in a delusional leap through a window during a tense meeting with the institute’s chairman—an act that nearly kills him and traps him in a recurring dreamscape shaped by a former patient’s fractured psyche. This chaotic parade of cultural icons and animated objects demands Paprika’s intervention to break its hold. Rescued but marked by vulnerability, he aids the investigation into the theft, uncovering colleague’s assistant Kei Himuro’s involvement. As dream and reality collapse under the DC Mini’s misuse, he confronts mortal peril within a destabilized dream world, narrowly surviving a giant doll’s attack through Paprika’s aid. His administrative authority contrasts with subtle defiance of corporate norms, exemplified by sandals worn in formal settings—a quirk underscoring his unorthodox streak. Though initially projecting stability, his psychological fragility surfaces post-breakdown, exposing reliance on external saviors. His recovery and ongoing collaboration with the team reflect resilience, yet his arc remains secondary to broader narrative currents. Across documented accounts, his role endures as a supportive but flawed figure navigating the ethical labyrinth of dream technology.
