The Crane Couple’s Guest Quarters are located within a castle in the guest area designated for dignitaries. The quarters are occupied by Doji Masato and Doji Miho, a married couple who bear a slight family resemblance to Doji Setsuna. The quarters feature a ceiling panel that can be shifted for access to roof spaces and a floorboard that can be pried up, suggesting potential hidden compartments.
During a tea gathering, Kakita Kazumi and Bayushi Monban entered the guest quarters under the pretense of an investigation. Kakita Kazumi discovered a shifted ceiling panel containing a rope and a Thick Black Hemp Bag slick with oily residue, later identified as containing Firebiter Poison. The bag was hidden above the ceiling, and the rope would allow covert access across the guest quarters. Following this discovery, the Governor Miya Tetsuya was informed, and the Crane couple was placed under guard pending further investigation. The leather bag containing the poisoned bag was left in the sun and ignited, destroying its contents.
