Saiminjutsu Nyuumon

Tatsuhiko frequently visits his former high school friend Hayashi, now a university professor, during the Taisho era in Japan. During one visit, Tatsuhiko brings up the growing popularity of hypnosis in society. Skeptical of its power, Hayashi proposes a test. Tatsuhiko then applies a hypnosis technique on Hayashi, after which his friend begins to act oddly.
