Method Validation of SF Prototyping – Toppema Case

This activity used the story of Toppema as material, but the main focus was on verifying the methodology of SF prototyping.
Instead of providing a detailed narrative, we decomposed it into reproducible steps — worldbuilding, scenario work, and ELSI design — and organized a framework that can be transferred to future social implementation, exhibitions, and dialogues.

Workflow

• Step 1: Survey existing research, institutions, and market trends to draft a hypothetical timeline
• Step 2: Move between micro daily-life scenes and macro societal contexts to synthesize narratives
• Step 3: Review from ELSI, inclusivity, and feasibility perspectives

Story Summary

Born from a failed genetic modification experiment, the cat Toppema awakens as a special being connected to a quantum network and encounters Noriko in the city.
As the device DreamSphere that manipulates dreams threatens Noriko’s memory and sleep, Toppema struggles to save her through quantum entanglement.
Told from the perspective of a cat, this narrative questions how quantum technologies impact human intelligence, dreams, and views of life and death.

Future Development

Going forward, we aim not only to explore the Toppema case, but also to further systematize SF prototyping as a methodology.
