Summary
Hikagemachi, a town where many yokai live in human form. To oversee the yokai inhabitants, the imperial capital formed a top secret group of agents called the Katanashu. The newest member is a young man known as Momiji.

Despite his bewiderment at the the unique aspects of a world populated by non-humans, Momiji feels a strange sense of nostalgia. In the midst of his arrival, an incident occurs in Hikagemachi. A case, not of manslaughter, but of yokai-slaughter.

The town's yokai point to the obvious sword wounds, asking how it could be anything, but a human's doing. The Katanashu agree to undertake a certain suggestion made by the great yokai Karasutengu to prove their innocence.

Elsewhere, the Kemonotsuki are attempting to get their hands on the "Kaleidoscope that Reveals Sins", an item owned by the yokai Ungaikyo. What could their purpose be...?
