One night in Edo, a mysterious woman in a palanquin appeared at the moneylender Yamashiroya, revealing herself to a beautiful woman. She told the owner, Shigebē, that she had come to collect a life he owed from twenty years ago and then left. The same night, Maruiya Genbē also received a visit from the woman's palanquin, and nearby, a man named Manbē was murdered. The detective Hayanawa Gohē concluded the murder was the work of a fox spirit, but another detective, Den Shichi, skeptical of this theory, noticed footprints on the tatami and decided to investigate further.
