Kashou no Tsuki: Aki Kyougen

Near the end of the Kamakura era, the gifted ritualist Arimasa Tsuchimikado serves the military government while enduring suspicion over his part-fox ancestry. Beside him is Kagetsu, a being able to take both human and feline form, whose connection to Arimasa reaches back into their past.

When Regent Houjou Takatoki's double is attacked and Arimasa's fan is found at the scene, prejudice hardens into an accusation. The incident conceals a scheme within the struggle between the imperial court and the shogunate, entangling his bond with Kagetsu in a threat larger than either of their lives.
