Supervision: Kyoto University Mystery-Solving Production Group 'Hardnuts'
A mystery-solving production group centered around Kyoto University students. Formed in 2015 by members of the medical faculty, they debuted with the performance 'Escape from the Human Body'. Since then, they have hosted numerous independent mystery-solving events and corporate collaborations not only in the Kansai region but nationwide. The name 'Hardnuts' originates from the English term for a difficult problem. It reflects the idea that even for a tough, hard-to-crack problem, once you break the shell and solve it, a delicious and fascinating experience awaits.
