Dr. Torataro Shima leads the research team at the Institute of Psychiatric Research, shepherding development of the revolutionary DC Mini device for dream therapy. He is a respected, influential figure known for his progressive psychiatric methods and strong commitment to patient welfare. His leadership requires navigating institutional administrative and political hurdles, sometimes causing frustration despite his dedication to ethical technological advancement. An elderly man of slight stature, Shima has white hair and brown eyes. His most distinctive feature is exceptionally thick eyeglasses that dramatically enlarge his eyes, rendering him nearly unrecognizable without them. He often wears sandals, reflecting his practical, unorthodox demeanor. Shima exhibits a cheerful, bubbly personality and is generally supportive of his team, particularly Dr. Atsuko Chiba and DC Mini inventor Dr. Kosaku Tokita. He facilitates early practical tests of the device, demonstrating trust in their work. A personal dimension exists with Chiba, as her dream alter ego Paprika once helped him overcome depression, fostering deep loyalty. When multiple DC Mini prototypes are stolen, Shima becomes an early victim of their malicious use. He succumbs to a mental breakdown, speaking nonsensical gibberish before attempting suicide by leaping through a window. This near-fatal event leaves him comatose and trapped in a recurring dream—a surreal, chaotic parade—where his psyche assimilates into the collective unconsciousness of other infected victims. Within this dream, he manifests as a grotesque figure composed of dolls. Paprika intervenes to rescue Shima from the dream's control. Following recovery, he collaborates closely with her and Detective Konakawa to confront the escalating crisis. During the climax, as dreams merge with reality and the chaotic parade engulfs the city, Shima is nearly killed by a giant Japanese doll but saved by Paprika. He subsequently participates in efforts to contain the disaster, demonstrating resilience despite his trauma.
